ENGLISH ABSTRACT: The purpose of this study was to explore the knowledge of tennis tactics of a group of South African tennis coaches. A secondary purpose was to gather their perceptions about where they believe they learned about tactics. A mixed methodology approach was used. The first was a quantitative knowledge test administered to 37 coaches. The second was a qualitative semi-structured interview with five coaches. The results of the study showed that there was a significant difference in the choices of tactical options in 43 game scenarios between the less experienced and the more experienced coaches. No differences were found between coaches who were coaching at the top level compared to the lower levels. No differences were found between coaches who had been top tennis players and those who had not. The majority of the coaches in this study reported that they had learned tactics through trial and error. Problems facing the development of top level tennis coaches in South Africa are discussed in relation to their knowledge of tactics and the priorities for the development of mass participation supported by national sport policy.
AFRIKAANSE OPSOMMING: Die hoofdoel van hierdie studie was om ŉ groep Suid-Afrikaanse tennisafrigters se kennis van tennistaktiek te ondersoek. ŉ Sekondêre doel was om uit te vind waar die afrigters glo hulle sodanige kennis opgedoen het. Die navorsingsbenadering het uit gemengde metodologieë bestaan. Die eerste was ŉ kwantitatiewe kennistoets wat onder 37 afrigters afgeneem is. Die tweede was ŉ kwalitatiewe semigestruktureerde onderhoud met vyf afrigters. Die resultate van die studie dui daarop dat die minder ervare en meer ervare afrigters geen beduidende verskil getoon het in hul taktiese keuses in 43 wedstrydscenario’s nie. Geen verskil is opgemerk tussen afrigters op die topvlak en dié op laer vlakke nie. Boonop was daar geen verskil tussen afrigters wat eens topspelers was en diegene wat nié was nie. Volgens die meeste van die afrigters in die studie het hulle hul kennis van tennistaktiek deur die metode van leer en probeer opgedoen. Die studie bespreek die uitdagings in die ontwikkeling van topvlaktennisafrigters in Suid-Afrika wat betref hul kennis van taktiek en die prioriteite vir die bevordering van massadeelname ingevolge nasionale sportbeleid.

Abstract:

Despite the considerable body of literature describing the demands of tennis, little is known about the accumulated physiological and mechanical loads associated with collegiate tennis tournament play. While microsensors have been used extensively to quantify demands in a variety of sports, particularly accelerometry and GPS sensors, limited data exists describing the demands of tennis match play using such microsensors (1,2). Aim. The purpose of this study was to use heart rate sensors and triaxial accelerometers to investigate the physiological and mechanical loads associated singles and doubles' tennis play during a single elimination collegiate tennis tournament.

Resumo: Esse estudo promove, no primeiro momento, uma discussão teórica acerca da Pedagogia do Esporte e da iniciação esportiva ao Tênis de Campo. As reflexões basearam-se a partir dos autores que defendem a proposta pedagógica do Teaching Games For Understanding (TGFU). No decorrer das discussões teóricas, foi realizado um diálogo entre as propostas desses autores e as reflexões de autores brasileiros que abordam o tema da Pedagogia do Esporte. É importante ressaltar que, a partir do encontro e da comparação das propostas de dois grupos de autores, é possível contribuir de maneira significativa para avanços da produção teórica no tema da Pedagogia do Esporte e Iniciação Esportiva. Além de contribuir com a construção de um referencial teórico, este estudo teve como objetivo verificar quais as características da Iniciação Esportiva nos 4 principais clubes do Estado de São Paulo. Para isso, foi realizada uma pesquisa de campo dividida em dois momentos: realização de entrevistas semi-estruturadas com os professores envolvidos com as aulas de iniciação esportiva nos clubes e a realização de observações não-participantes das aulas ministradas por esses professores. O objetivo das entrevistas foi o de verificar o perfil do profissional que trabalha com a iniciação esportiva à modalidade: sua formação escolar, sua experiência com a modalidade e, principalmente o de constatar quais os principais conteúdos que eles consideram que devem ser trabalhados em aulas de iniciação esportiva ao Tênis de Campo. O objetivo da observação das aulas foi o de constatar quais os conteúdos trabalhados nas aulas e quais os procedimentos pedagógicos utilizados pelo professores. A partir da pesquisa de campo, constatou-se que a maioria dos professores entrevistados não possui formação acadêmica em Educação Física, todos eles possuíam vivência na modalidade antes de se tornarem professores, e acreditavam que o ensino dos elementos técnicos da modalidade corresponde ao principal conteúdo a ser ensinado nas aulas de iniciação esportiva. Em relação aos conteúdos trabalhados durante as aulas, foi possível constatar que a preocupação central da maioria das aulas ainda é a de ensinar as habilidades técnicas da modalidade. Nesse sentido, verificamos uma disparidade entre as propostas pedagógicas de ensino do Tênis de Campo e o contexto da iniciação esportiva à modalidade constatado a partir da pesquisa de campo.
Abstract: This study promotes, initially, a theoretical discussion about Sport Pedagogy and sport initiation to Tennis. The reflections were based upon the Teaching Games For Understanding (TGFU) proposal. During the theoretical discussions, we proposed an dialogue between the TGFU ideas and the reflections of Brazilian authors that discuss Sport Pedagogy. It is important to point out that through these comparisons of two different proposals it is possible to contribute to the development of the theoretical productions of Sport Pedagogy. Besides these theoretical contributions, this study aims to verify the characteristics of sport initiation to Tennis in the 4 biggest sport clubs in the state of São Paulo. In order to do that, a field research took place in these clubs. This research was divided in two moments: first we interviewed the teachers responsible for the Tennis classes and, afterwards, we observed the classes. The purpose of the interviews was to get to know the profile of this professional involved in the process of sport initiation: the scholar level, the professional experience and, most importantly, verify what are the aspects of sport initiation classes that they consider to be more relevant in the classes. The purpose of the observation was to verify what activities are proposed during the classes. The field research showed that most of the teachers do not have a graduation degree in Physical Education, and all of them had some experience in Tennis before becoming teachers, also most of them believed that teaching the techniques should be the main purpose of the classes. Through the classes observation, it is possible to establish that most of the classes are based upon the goal of teaching technique skills. Thus, it is possible to see a disparity between the pedagogical proposals researched in the literature and the characteristics verified through the field research.

ENGLISH ABSTRACT: Feedback is critical for motor skill learning. Knowledge of performance (KP) In the form of verbal feedback is the most commonly used type of augmented feedback. Advances in technology have made it possible for coaches to utilise video-supported feedback with athletes with the intention of accelerating the learning process. The use of videotape replay has been an effective aid under some circumstances. Recent commercially available products offer digital analysis that may be even more successful than ordinary video replay in this regard. The purpose of this study was to determine the effectiveness of knowledge of results (KR) and verbal KP with video-support in improving the learning of the tennis serve, when compared to KR with verbal KP only. A total of 18 adults (lOwomen and 8 men) were assessed on their serving technique (6 kinematic variables), accuracy (2 variables) and speed (1 variable). Technique analysis was completed using a commercially available analysis programme. For a short intervention period, one group (n = 10) received KR with verbal feedback only, while the other group (n = 8) received KR plus verbal feedback with video support. The subjects were tested after the intervention to see what changes had occurred with regards to the speed, accuracy and technique of their serves. No significant differences were found for any of the variables, leading to the conclusion that the amount oftime spent in the intervention programme must be extended in order to possibly achieve significant effects on performances.
AFRIKAANSE OPSOMMING: By die aanleer van motoriese vaardighede is terugvoer van kritiese belang. Verbale terugvoering is die mees algemene vorm van kennis oordraging aan die uitvoerder. Verbetering in tegnologie het dit nou moontlik gemaak vir afrigters om videoondersteunde terugvoer met atlete te gebruik, met die doelom die leerproses te versnel. Die gebruik hiervan is in sekere situasies 'n effektiewe hulpmiddel. Kommersiële produkte wat tans beskikbaar is bied die moontlikheid van digitale ontledings, wat dalk meer suksesvol kan wees as slegs die terugspeel van 'n video aan die uitvoerder. Die doel van hierdie studie was om die doeltreffendheid van kennis van resultate (knowledge of results) en verbale terugvoering met video-ondersteuning in die verbetering van die tennis afslaan te meet, en dit dan te vergelyk met kennis van resultate waar net verbale terugvoering verskaf is. 'n Totaal van 18 volwassenes (It) vroue en 8 mans) se afslaantegniek (6 kinematiese verandelikes), akkuraatheid van afslaan (2 verandelikes) en die spoed van die afslaan (1 verandelike) is nagegaan. Tegniekontleding is met die gebruik van 'n komersieël beskikbare analise-program gedoen. Een groep (n = l O) het kennis van resultate en verbale terugvoer gekry vir 'n kort intervensie periode. Die ander groep (n = 8) het kennis van resultate en video-ondersteunde verbale terugvoer, ook vir 'n kort intervensie tydperk ontvang. Die deelnemers is na afloop van die intervensie tydperk getoets om te bepaal watter veranderinge met betrekking tot spoed, akkuraatheid en afslaantegniek plaasgevind het. Geen beduidende verskille is in enige van die verandelikes gevind nie. Dit gee aanleiding tot 'n gevolgtrekking dat die duur van die intervensieprogram verleng moet word om 'n beduidende effek op uitvoering te kry.

Abstract:

The purpose of the present study was to examine the role of timeouts in competitive elite table tennis in relation to psychological momentum (PM). To that end, archival data from elite top-international matches (N= 48) was firstly examined to gather information on when timeouts are most taken, and whether these have any objective influence on subsequent performance (set outcome and ultimately match outcome). Secondly, similar archival data for Swedish League matches (N= 36) was examined and interviews with elite coaches from the highest Swedish league (N= 6) at these given matches were carried out to gain further knowledge and understanding on the role and use of timeouts in competitive elite table tennis. Findings showed that timeouts were mostly called following a sequence of three consecutive lost points; that is, coaches used timeouts to break negative PM. However, findings also showed that these given timeouts had no objective impact on neither set nor match outcomes; that is, sets and matches were ultimately lost. Future research examining the subjective coach-player experience revolving around timeouts is needed to comprehend potential ‘secondary’ purposes when calling timeouts and, subsequently, understand timeouts role in table tennis fully.

Abstract:

Although there currently exists an in-depth empirical understanding of parents experiences and involvement in youth sport, there is an absence of published field-based intervention research specifically with sport parents (Harwood & Knight, 2015). In order to address this gap in the literature, this thesis developed a psychosocial parent education programme for British Tennis. The first study identified the education and support needs of tennis parents operating within British high performance centres (study one). Adopting a grounded theory design, data were collected through informal chats, observations, and formal interviews with parents, coaches, and ex-youth players (n=29) during a six-month period of fieldwork. Findings revealed how parents education and support needs occur across multiple levels of functioning (i.e., social, organisational, developmental, and intra-interpersonal) and are influenced by the developmental stage that parents operate in. This theoretical framework was then used as the basis for a group-based tennis parent education programme (study two). Using a qualitative organisational action research framework seven workshops were run over a 12-week period for parents with children between the ages of 5 and 10 years. Participant diaries, social validation feedback forms, and post programme focus groups (n=19) revealed perceived improvements in parents knowledge, affect, and skills across a range of learning objectives. In an attempt to improve accessibility and extend participation, the final study utilised a convergent parallel mixed methods design to examine the effectiveness of an online education programme for British tennis parents (n=38) and their perceptions of engaging in the programme (study three). Quantitative findings revealed positive directional changes in tennis parent efficacy, general parent efficacy, emotional experiences, and achievement goal orientations after completing the programme. Qualitative data provided complementary and unique insights into what worked, how, and why. Taken together, the studies within this thesis are the first to demonstrate the effectiveness of face-to-face and online sport parent education programmes. Findings also extend and advance existing recommendations and guidelines in relation to the design, development, implementation, and evaluation of education programmes for sport parents. In particular, studies illustrate the importance and value of providing sport parents with accessible, proactive, structured, and developmentally appropriate education and support which addresses their stage-specific needs.

ENGLISH ABSTRACT: The purpose of this study is to investigate the role of sport psychology injunior tennis and to determine: • whether coaches make use of psychological interventions, • whether coaches consider psychological interventions in junior tennis to be important, • what kind of psychological interventions coaches make use of, and • what kind of problems coaches encounter while teaching psychological interventions to junior tennis players. Questionnaires were mailed off to all professional tennis coaches who are registered with Tennis South Africa. The questionnaire which the coaches voluntarily answered, was an abbreviated, revised version of the questionnaire used by Gould et al. (1999a) for their study. \ The results of this study show that coaches: • regard the teaching of psychological interventions to junior tennis players as very important. • perceived the following as the most important psychological dimensions for junior tennis players: motivation, concentration, enjoyment, self-confidence and goal setting. • find the teaching process of psychological interventions to junior tennis players difficult. • encounter practical problems in the teaching of psychological interventions to junior tennis players. Lack of time is mentioned most often. Based on these outcomes, it is concluded that sport psychology has an important role to play in junior tennis. More research is needed to develop techniques and methods to effectively teach psychological interventions to junior tennis players.
AFRIKAANSE OPSOMMING: Die doel van die studie is om die rol van sportsielkunde in junior tennis te ondersoek deur die volgende te bepaal: • of afrigters van sielkundige intervensies gebruik maak, • of afrigters dink dat sielkundige intervensies belangrik is in junior tennis, • van watter sielkundige intervensies afrigters gebruik maak, en • watter probleme afrigters ondervind gedurende die onderrig van sielkundige intervensies aan junior tennisspelers. Vraelyste is gestuur aan aIle professionele tennisafrigters wat by Tennis Suid-Afrika geregistreer is. Die vraelys wat die afrigters vrywillig beantwoord het, was 'n verkorte, hersiene weergawe van die vraelys wat deur Gould et al. (1999a) in hulle studie gebruik is. Die resultate van die studie toon dat afrigters: • die onderrig van sielkundige intervensies aan junior tennisspelers as belangrik beskou. • die volgende sielkundige dimensies in junior tennis as die belangrikste beskou: motivering, konsentrasie, genot, selfvertroue en doelwitstelling. • die onderrigproses verbonde aan sielkundige intervensies moeilik vind. • praktiese probleme ondervind met die onderrig van sielkundige intervensies aan junior tennisspelers. 'n Gebrek aan tyd is uitgesonder as die probleem wat die meeste voorkom. Gebaseer op die resuitate, is daar tot die gevolgtrekking gekom dat sportsieikunde 'n belangrike rol te speel het in junior tennis. Verdere navorsing word benodig am tegnieke en metodes daar te stel om die sieikundige intervensies effektief aan junior tennisspelers te onderrig .

Syfte och frågeställningar Syftet med detta arbete var att undersöka tennistränarens användning av mental träning. - Hur viktigt är det med mental träning? - Vad är tränarens upplevelse av självprat och mentala föreställningar? - Hur tillämpar tränarna självprat på sina spelare? - Hur tillämpar tränarna mentala föreställningar på sina spelare? Metod Studiens ansats var kvalitativ där intervjuer användes. Det genomfördes fyra intervjuer med tennistränare för elitspelare i åldrarna 13-17 i olika klubbar i Stockholm. Intervjuerna spelades in och transkriberades. Därefter analyserades och tolkades intervjuerna på ett induktivt sätt där tanken alltid var att fokusera på att hitta kategorier som kopplar till studiens syfte och frågeställningar. Resultat Resultaten som presenteras i studien är baserade på gemensamma kategorier som hittades i intervjuerna. Resultaten visar hur viktigt det är med mental träning samt tränarnas egna erfarenheter och upplevelser kring mental träning inom tennis med fokus på självprat och mentala föreställningar. Slutsats Tränarna i denna studie arbetar oorganiserat med mental träning. De anser att mental träningär viktigt och skulle vilja ha mer tid för att utföra det på ett mer konkret sätt. De menar att man ska lära spelarna att acceptera känslorna som kan ta över en situation och hitta rätt verktyg

Abstract:

Tennis är en sport som ständigt förändras. Nya data som analytikern Craig O'Shannessy tagit fram visar att en klar majoritet av alla poäng är korta, det vill säga poäng som innehåller fyra eller färre slag. Den spelare som vinner flest av dessa tenderar även att stå som segrare i slutet av matchen. Målet med det här arbetet är att undersöka WTA-turneringen Sydney International 2018 för att se om samma mönster går att hitta där och, om så är fallet undersöka om det finns några skillnader mellan hur olika grupper presterar. Ett par exempel på grupper är matchvinnare mot förlorare och seedade mot oseedade spelare. Det visade sig att poänglängderna nästan var identiska med O'Shannessys resultat och de hade påverkan på utgången av matcherna. Vidare så låg matchvinnarna högre i de flesta kategorierna som exempelvis andelen servar och returer in och andelen vunna. Gällande serve+1 så höll de en jämn nivå både på forehand- och backhandsidan, jämfört med de förlorande spelarna som hade problem med backhanden. Däremot gick det inte att se några tydliga skillnader i serve- och returmönster, bortsett från andraservar till deuce court. Utifrån resultaten så verkar kvaliteten på slagen vara mer avgörande än var i banan som de landar.
Tennis is an everchanging sport. New data from tennis analyst Craig O'Shannessy show that a vast majority of points are short, i.e. points decided in four or fewer shots. The player who wins most of them also tends to be the winner. The purpose of this paper is to examine the WTA tournament Sydney International 2018 to see if the same pattern occurs there and if that is the case investigate if there is any difference between how different groups are performing. A few examples of groups are match-winners against losers and seeded against unseeded players. It turns out that the lengths of the points were almost identical to O'Shannessy’s results and they influenced the matches outcome. Furthermore, match winners performed better in most categories, for example, the ratio of serves and returns in play and won. Regarding serve+1 they were able to keep an even level on both forehand and backhand side, while the losing players had some problems with their backhands. With that said, there were no clear differences in serve and return patterns, apart from second serves to the deuce court. From the results, it seems like the quality of the shots is more important than where they are landing.

Abstract:

L'objectif de ce travail est d'atteindre à une meilleure connaissance du comportement dynamique d'une raquette de tennis. La première partie de cette étude propose la modélisation par éléments finis du cadre. Pour tenir compte de la réalité des réalisations industrielles on a construit un élément fini équivalent de poutre qui peut représenter n'importe quelle section composite hétérogène de forme quelconque. Les performances de cet élément sont testées sur plusieurs exemples. Dans la deuxième partie, on s'intéresse à la représentation du tamis qui est faite plus classiquement par des éléments de corde en grandes dé format ions. L'ensemble tamis + cadre est ensuite analysé en tenant compte des contraintes initiales introduites par la mise en tension des cordes. L'accord expérience - calcul au niveau des fréquences et modes de vibration de divers types de raquettes est très bon que cela soit pour des raquettes métal ou composite. Dans une troisième partie on aborde le problème de l'impact en étudiant diverses modélisations sans cependant vouloir représenter la balle. On étudie par ailleurs un dispositif expérimental destiné à simuler le choc dans des conditions reproductibles. Les premiers résultats obtenus avec ce dispositif sont analysés ainsi que les difficultés rencontrées pour aller plus loin dans ces expérimentations et leur interprétation.

Abstract:

All athletes dream of competing to their full potential. Experimenters have shown that mental preparation can enhance performance. Self-efficacy and self-confidence have also been shown to have a direct relationship with performance. The purpose of this study was to investigate the potential of team highlight videotapes as mental preparation tools designed to enhance feelings of self-efficacy and sport-confidence, which in turn might lead to enhanced performance. Three-minute video montages of successful shot-making were set to music, with key words (words chosen to encourage or to emphasize a good shot) added throughout. Forty-seven competitive female tennis players were randomly assigned to one of two groups. The highlight videotape group was shown the team highlight videotape, while the control group was shown a neutral videotape. All participants completed Vealey's (1986) State Sport-Confidence Inventory (SSCI) and the Tennis Self-Efficacy Scale for Doubles (TSESD), watched their assigned videotape and then retook the SSCI and TSESD. Participants then completed a set of open-ended questions about the procedure.
The data was analyzed with a Group (2) x Level of skill (4) repeated measures design. The analysis of variance of the TSESD and SSCI scores did not reveal any significant differences between the scores of the treatment and control groups. But comments to the open-ended questions seemed to reveal increased feelings of sport confidence, motivation and arousal associated with the videotapes, suggesting that the team highlight videotapes may have potential as mental preparation tools. Additional research is warranted to further explore the potential uses of this new mental preparation tool.

It is well understood that multiple video cameras and computer vision (CV) technology can be used in sport for match officiating, statistics and player performance analysis. A review of the literature reveals a number of existing solutions, both commercial and theoretical, within this domain. However, these solutions are expensive and often complex in their installation. The hypothesis for this research states that by considering only changes in ball motion, automatic event classification is achievable with low-cost monocular video recording devices, without the need for 3-dimensional (3D) positional ball data and representation. The focus of this research is a rigorous empirical study of low cost single consumer-grade video camera solutions applied to table tennis, confirming that monocular CV based detected ball location data contains sufficient information to enable key match-play events to be recognised and measured. In total a library of 276 event-based video sequences, using a range of recording hardware, were produced for this research. The research has four key considerations: i) an investigation into an effective recording environment with minimum configuration and calibration, ii) the selection and optimisation of a CV algorithm to detect the ball from the resulting single source video data, iii) validation of the accuracy of the 2-dimensional (2D) CV data for motion change detection, and iv) the data requirements and processing techniques necessary to automatically detect changes in ball motion and match those to match-play events. Throughout the thesis, table tennis has been chosen as the example sport for observational and experimental analysis since it offers a number of specific CV challenges due to the relatively high ball speed (in excess of 100kph) and small ball size (40mm in diameter). Furthermore, the inherent rules of table tennis show potential for a monocular based event classification vision system. As the initial stage, a proposed optimum location and configuration of the single camera is defined. Next, the selection of a CV algorithm is critical in obtaining usable ball motion data. It is shown in this research that segmentation processes vary in their ball detection capabilities and location out-puts, which ultimately affects the ability of automated event detection and decision making solutions. Therefore, a comparison of CV algorithms is necessary to establish confidence in the accuracy of the derived location of the ball. As part of the research, a CV software environment has been developed to allow robust, repeatable and direct comparisons between different CV algorithms. An event based method of evaluating the success of a CV algorithm is proposed. Comparison of CV algorithms is made against the novel Efficacy Metric Set (EMS), producing a measurable Relative Efficacy Index (REI). Within the context of this low cost, single camera ball trajectory and event investigation, experimental results provided show that the Horn-Schunck Optical Flow algorithm, with a REI of 163.5 is the most successful method when compared to a discrete selection of CV detection and extraction techniques gathered from the literature review. Furthermore, evidence based data from the REI also suggests switching to the Canny edge detector (a REI of 186.4) for segmentation of the ball when in close proximity to the net. In addition to and in support of the data generated from the CV software environment, a novel method is presented for producing simultaneous data from 3D marker based recordings, reduced to 2D and compared directly to the CV output to establish comparative time-resolved data for the ball location. It is proposed here that a continuous scale factor, based on the known dimensions of the ball, is incorporated at every frame. Using this method, comparison results show a mean accuracy of 3.01mm when applied to a selection of nineteen video sequences and events. This tolerance is within 10% of the diameter of the ball and accountable by the limits of image resolution. Further experimental results demonstrate the ability to identify a number of match-play events from a monocular image sequence using a combination of the suggested optimum algorithm and ball motion analysis methods. The results show a promising application of 2D based CV processing to match-play event classification with an overall success rate of 95.9%. The majority of failures occur when the ball, during returns and services, is partially occluded by either the player or racket, due to the inherent problem of using a monocular recording device. Finally, the thesis proposes further research and extensions for developing and implementing monocular based CV processing of motion based event analysis and classification in a wider range of applications.

Abstract:

The study was initiated by Swedish Tennis Syd in collaboration with Halmstad University with the intention to examine the existing tennis talent development environments for 13-16 years of age players. The purpose of the study was to (1) examine the retrospective experiences of the talent de- velopment environments among players who already passed the focal age, (2) examine the retro- spective and concurrent experiences of the talent development environments among tennis coaches, and (3) examine the concurrent experience of the talent development environments among parents whose kids were active in tennis in the focal age. The study involved 14 participants whom had connection to tennis clubs within Swedish Tennis Syd’s working region. Data were collected through three focus groups interviews consisting of players, coaches, and parents. Eight major themes emerged from the data analysis: atmosphere in the clubs, organization of the training groups, amount of training, quality of the training, access to expert assistance, amount of competi- tion, combination of school and tennis, and, parental involvement. Each theme was analyzed within the group and across the three groups. The results revealed perceptions of the clubs environments and future recommendation to improve the talent development environments for tennis players of 13-16 years old.

Abstract:

The purpose of this research is to analyse the process of South Korean nationalism and national identity construction through studying Chinese table tennis players that have become naturalised citizens of South Korea. Based on an Eliasian theoretical and methodological prospective, this research employs three different methods of analysis. First, it employs archival analysis in the historical context chapter to determine the origins of table tennis and its spread to Northeast Asia, the political and societal role of table tennis in China and South Korea, and the appearance of the first naturalised player in South Korea. Second, this study employs newspaper text analysis to investigate newspaper reports of the South Korean and Chinese table tennis matches from the 1988 Seoul Olympics Games to the 2012 Games in London. This section first examines the flow of Korean nationalism through the table tennis matches between Korea and China, and then explores how the newspaper reports expressed nationalism in regard to the Korean players and naturalised players. Third, this study employs an interview method to gather data from 17 interviewees who have been associated directly or indirectly associated with the Chinese naturalised table tennis players in order to further examine the process of the formation of South Korean national identity. The first analysis regarding historical findings identifies that table tennis has evolved precisely alongside Elias s sportisation theory. In South Korea and China, table tennis has played the role of a national sport. Especially in South Korea, table tennis was a nationalistic sport that opposed anti-colonialism and anti-communism. It was in table tennis that the first naturalised athlete in the history of South Korean sport was selected for the Olympics. In the second analysis, through examining news reports of the Olympic table tennis matches between China and South Korea, this research identifies that South Korean newspapers continue to generate a strong image of nationalism. Moreover, the newspaper reports do not use the same nationalistic sentiments and personal pronouns for South Korean players and naturalised players. Finally, the interview analysis investigates the formation of South Korean identity through the naturalised table tennis players in South Korea. Three national identities groups have arisen in South Korea in response to the emergence of naturalised athletes. The first group approves of globalisation and naturalisation. The second group opposes globalisation and naturalisation. The third group, which comprises the media, has no specific interest in globalisation and naturalisation, but has an identity that changes based on the interests of the media company. In other words, the evidence from the interviews carried out for this thesis shows that South Korean national identity in regard to naturalised athletes remains diversified and not unified.

Abstract Titel: Svenska tennisgymnasium vs. Akademin ”Good to Great” Nivå: C-uppsats inom Idrottsvetenskap Författare: Andreas Moberg & Gabbi Tepic Handledare: Marie Hedberg Datum: Maj 2013 Syfte/Metod Syftet med denna uppsats är att identifiera två stora tennisgymnasium kontra tennisakademin i Stockholm. Hur ser de olika verksamheterna ut och vilken typ av ledarskap förespråkar tränarna på respektive plats. Vi valde att fokusera på vad tränarna förordar för bakgrund och utbildning för att leda elitspelare. Vid genomförandet av vår studie valde vi att använda en kvalitativ metod, eftersom vi ansåg att det var den som passade absolut bäst för vår studie. Slutsats Respondenterna hade väldigt olika uppfattningar om en duktig tränares bakgrund. Tränarna vid akademin kände att en tidigare spelarkarriär var viktig när det gällde coaching för spelare på hög nivå. I Båstad var det mer att man ansåg det vara viktigt att ha en mix som ledare och i Malmö pekades det på att en egen spelarkarriär inte betydde så mycket. Det skilde sig åt en del i planering, vid akademin, är det mycket resor och tävlingar och på tennisgymnasierna är det en blandning av god utbildning i kombination med tennis som gäller. Bidrag Det finns i dagsläget inga uppsatser om just detta ämne tidigare, bara rapporter angående Sveriges storhetstid i tennis. Därför hoppas vi att denna studie kan ge viktig och intressant information om Svensk tennis och vårt ledarskap idag. Varför tränarna föredrar det dem genomför har vi undersökt en hel del. Det finns tydliga skillnader idag jämfört med när den Svensk tennis var en ledande nation, som vi också har diskuterat och analyserat kring. Nyckelord: Ledarskap, träningsfilosofi, utbildning & faktorer för framgång.

Abstract:

Sedan många år tillbaka har elitsatsning på barn- och ungdomar fått stor uppmärksamhet i media. Rapporteringen från media om tennisspelande juniorer som elitsatsar har skapat stora och hätska reaktioner inom både tennissverige, men även idrottssverige. Med avstamp i medias debatt om elitsatsning, ämnar följande arbete undersöka på vilket sätt tennisklubbar i Sverige möjliggör elitsatsning för juniorer upp till 18 år. För att studiens syfte skulle uppnås använde sig studien utav en ”mixed method”. En enkätundersökning skickades ut till de 40 största tennisklubbarna i Sverige, till antalet medlemmar sett. För att vidare kunna få en djupare förståelse och för att kunna fånga upp tankar, känslor och upplevelser så genomfördes semi-strukturerade intervjuer med 9 olika tennisklubbar som i någon form bedriver en elitverksamhet. Resultatet visade att tennisklubbar möjliggör elitsatsning för juniorer på en rad olika sätt, beroende på tennisklubbens verksamhet, storlek, resurser i form av faciliteter och ekonomiska resurser. Tennisklubbarna har påverkats i olika stor utsträckning utav medias debatt om elitsatsning. Några tennisklubbar har påverkats mycket och därav fått ändra i sin verksamhet, medans några andra tennisklubbar enbart har påverkats lite eller ingenting alls. Vidare så visade resultatet att elit och elitverksamhet är ett svårdefinierat och problematiskt begrepp för många av tennisklubbarna.

Mestrado em Gestão de Recursos Humanos
Devido ao mundo global e às mudanças que este tem vindo a assinalar, um dos elementos chave para a vantagem competitiva das organizações que nele actuam é a criatividade, bem como o improviso. Nos últimos anos desenvolveram-se vários estudos sobre este mesmo tema, na área da gestão, que demonstram que essa vantagem competitiva ocorre quando a criatividade é abordada em função do seu contexto. Contudo, sendo a criatividade e o improviso inerentes ao ser humano, ambos também acabam por se manifestar em outras áreas da vida humana, como a música, a dança, o teatro e nomeadamente o desporto. Este trabalho visou perceber de que forma é que a criatividade e o improviso estão presentes no ténis de alta competição, como se manifestam, se é importante e sua existência, e que tipo de vantagens trazem para os jogadores. Teve como campo de estudo pessoas relacionadas com o ténis: jogadores, treinadores, árbitros e adeptos. Para a concretização dos objectivos previamente propostos, foram realizadas entrevistas de tipo semi-estruturadas, dirigidas presencialmente a 15 pessoas - 6 treinadores, 4 jogadores, 1 árbitro e 4 adeptos, tendo-se obtido uma taxa de 100% de participação. Estas entrevistas foram analisadas com base à técnica de análise de conteúdo temática (Bardin, 1977). Os resultados obtidos indicam que tanto a criatividade como o improviso estão presentes no ténis - talvez mais o improviso - sendo melhores descritos como identitários do ser jogador, ou seja, é necessário e importante que estas capacidades existam pois trazem vantagens aos jogadores.
Due to all the changes that happened on global world one of the key elements to have competitive advantage on organizations that act in it is: creativity and improvisation. In recent years we have developed several studies on this subject demonstrating that this competitive advantage occurs when creativity is addressed according to their context. However, with the creativity and improvisation inherent in the human being, eventually manifest itself in other áreas of human life, such as music, dance, theater and particulary sport. This study aim to understand how creativity and improvisation are present in top-level tennis, how are manifested, its importance and its existence, and what kind of benefits they bring to the players. It had as studie field people related to tennis: players, coaches, referees and fans. To meet the previously proposed objectives semi-structured type of interviews weres conducted in person addressed to 15 people - 6 coaches, 4 players, 1 referee and 4 fans, having obtained a rate of 100% stake. These interviews were analyzed using the thematic content analysis (Bardin, 1977). The results show that both creativity and improvisation are present in tennis - perhaps more improvisation - is best described as the identity of a player, and i tis necessary and important that these capabilities exist because they bring advantages to players.

Abstract:

The asymmetries detected in the different multi-directional sports vary in magnitude depending on the test selected. Furthermore, in the individual analysis of the different tests administered, it was observed that athlete’s lower limb preferences depended on the test. Greater asymmetries were detected in the vertical jump test, the CODD variable, and the change of direction with inertial resistance test in multidirectional sports. The change of direction with inertial resistance test also enabled us to detect asymmetries in actions that approximate the actual sport. Moreover, the results showed that asymmetries have a negative impact on performance of the jump and the change of direction, and on speed in the linear sprint and the capacity to repeat the change of direction. Last, we were able to observe that iso-inertial training results in greater adaptations in performance and larger reductions in asymmetries than conventional cable-resistance training. We can also affirm that positive adaptations in performance caused by resistance training are not necessarily associated with reduced asymmetries
Com a síntesis d’aquest procés d’investigació, les asimetries detectades en els diferents esports multidireccionals mostren variabilitat en les magnituds segons la prova seleccionada. A més, en l’anàlisis individuals les proves realitzades, s’ha pogut observar que els esportistes mostren preferències en l’habilitat de la cama en funció de la prova. El test de salt vertical, la variable del COD i canvi de direcció amb resistència iso-inercial mostra majors magnituds en la detecció d’asimetries en esports multidireccionals. El canvi de direcció amb resistència iso-inercial permet, detectar les asimetries en accions pròximes a l’esport. Per un altre costat, els nostres resultats també mostren que les asimetries influeixen negativament en el rendiment de salt, canvi de direcció, capacitat de repetir canvis de direcció i velocitat en esprint lineal. Per a finalitzar, hem pogut observar que l’entrenament iso-inercial provoca majors adaptacions en el rendiment i majors reduccions d’asimetries que l’entrenament de força convencional de cable gravitacional

Abstract:

Duale Prozessmodelle unterscheiden implizite und explizite Formen der Informations-verarbeitung (Strack & Deutsch, 2004). Implizite Verarbeitung erfolgt schnell und un-bewusst und basiert auf affektiv-assoziativen Netzwerken. Explizite Verarbeitung geschieht überlegt und langsam und beinhaltet bewusste, kognitive Entscheidungsprozesse. In dualen Prozessmodellen der Motivation sagen implizite Motive langfristiges Verhalten und explizite Motive bewusste Entscheidungen vorher (McClelland, et al., 1989). Hoher positiver Affekt sowie geringer negativer Affekt aktivieren implizite kognitive Systeme während eine entgegen gesetzte Ausprägung explizite Informationsverarbeitung bahnt (J. Kuhl, 2000a). Drei Feldstudien untersuchen die diskriminante Validität impliziter vs. expliziter motivationaler Prozesse für das Verhalten in unbewussten vs. bewussten kritischen Situatio-nen im Hochleistungssport. In Studie 1 und 2 wird bei Tennis- (N = 60) und Basketballspielern (N = 56) die Fähigkeit erhoben, positiven und negativen Affekt zu regulieren (ACS-90; J. Kuhl, 1994). In Studie 3 (N = 86) werden zusätzlich implizite (OMT; J. Kuhl & Scheffer, 1999) und explizite Motive (PRF; D. N. Jackson, 1999) sowie die Fähigkeit zur bewussten Selbstregulation (VCQ; J. Kuhl & Fuhrmann, 1998) gemessen. In Studie 1 sagen explizite Formen der Verarbeitung (niedrige positive Affektregulation) die Tennisleistung in objektiv kritischen (wie Tie Breaks) aber nicht in bewusst kritischen Situationen vorher. In Studie 2 führt implizite Verarbeitung (hohe negative Af-fektregulation) zu besseren Basketballleistungen in objektiv kritischen Spielen. In Studie 3 unterstützt explizite Verarbeitung Leistungen in bewusst kritischen Situationen im Rückschlagsport. In unbewusst kritischen Situationen erzielen dagegen Sportler mit ausgeprägten impliziten Motiven bessere Ergebnisse. Die Befunde werden hinsichtlich der Sportartenspezifik, dem Grad der Bewusstheit sowie Persönlichkeitsunterschiede diskutiert.
Dual-process models distinguish implicit and explicit ways of information processing (Strack & Deutsch, 2004). Implicit processes are based on associative affective networks and operate fast and unconsciously. Explicit processing is a cognitive, usually slow, deliberate, and conscious way of decision-making. Dual-process models of motivation propose that implicit motives predict long-term behavior and explicit motives predict deliberate decisions (McClelland, Koestner, & Weinberger, 1989). Up-regulation of positive affect and down-regulation of negative affect activate implicit cognitive systems while regulation in the opposite direction triggers explicit information processing (J. Kuhl, 2000a). Within three field studies it is investigated whether implicit vs. explicit motivational processes are of discriminant validity for professional athletic behavior in unconsciously vs. consciously critical situations. In study one and two, tennis (N = 60) and basketball professionals’ (N = 56) abilities to regulate positive and negative affect (ACS-90; J. Kuhl, 1994) are assessed. In study three (N = 86) the additional measures of implicit (OMT; J. Kuhl & Scheffer, 1999) and explicit motives (PRF; D. N. Jackson, 1999) as well as conscious self-regulation (VCQ; J. Kuhl & Fuhrmann, 1998) are used. Study one proposes that explicit processing supports performance in objective critical situations (tie breaks) in tennis. However, in consciously critical situations no advantage for explicitly processing athletes could be found. In study two implicitly processing basketball players perform better in objectively critical games. In the final study racquet sportsmen who process explicitly perform better in consciously critical situations. In contrast, in unconsciously critical situations athletes with high implicit motives gain better results. Findings are discussed from the perspective of task specificity, degree of awareness, and individual differences.

Abstract:

En aquesta Tesi Doctoral, s'ha fet una recerca sobre les instal·lacions dels clubs de tennis de Catalunya, amb la intenció de poder determinar-ne unes pautes de disseny. Atesa la particularitat d'aquest tipus d'instal·lació, que per la no poliesportivitat de l'espai de joc ha quedat fora de la Xarxa Bàsica especificada i estudiada per la Generalitat de Catalunya, s'ha cregut convenient endegar aquest estudi i aportar algunes consideracions per a la seva concepció i disseny. Cal remarcar la intenció d'estudiar la instal·lació en la complexitat amb la que ens la trobem habitualment, és a dir, distribuïda heterogèniament en el territori i constituïda per espais esportius, complementaris i auxiliars.
La fonamentació teòrica ha aportat la revisió de conceptes entorn l'espai esportiu i que fan referència a l'evolució històrica, la concepció urbanística i de planificació territorial, i la vessant sociològica. Posteriorment, i entrant en la fonamentació metodològica, s'ha fet una recerca aplicada en la mesura que s'han traslladat els conceptes recollits i revisats en el marc teòric dins de la realitat pròpia dels espais esportius de tennis, i a Catalunya. Per a dur a terme aquesta part, s'han desenvolupat propostes d'anàlisi geogràfica i territorial, esbrinant els motius de l'heterogènia distribució actual de pistes de tennis i determinant els dèficits territorials a través de l'aplicació de les eines existents del planejament.
La utilització d'aquestes eines ha facilitat la revisió dels paràmetres descriptius i classificatoris de les instal·lacions esportives, i ha permès determinar quins d'aquests paràmetres són definibles des del disseny i aplicables en el cas de les pistes de tennis. Aquest ha estat el punt de partida per a l'elaboració d'un instrument d'observació i estudi de l'espai esportiu concret (pista de tennis) en la realitat organitzativa en què sol trobar-se al nostre país (clubs).
A través de l'aplicació sobre una mostra representativa de clubs s'han cercat aquells valors del model d'anàlisi que han fet possible, per una banda acostar-se a la comprensió de l'objecte d'estudi i per altra esbrinar, amb la interrelació dels seus indicadors, els valors que proporcionen major idoneïtat quant al disseny en cada nivell d'observació.
En esta Tesis Doctoral, se ha planteado una investigación sobre las instalaciones de los clubes de tenis de Cataluña, con la intención de poder determinar unas pautas de diseño. Dada la particularidad de este tipo de instalación, que por la no poli deportividad del espacio de juego ha quedado fuera de la Xarxa Bàsica (Red Básica) especificada y estudiada por la Generalitat de Catalunya, se ha considerado conveniente realizar este estudio y aportar algunas consideraciones para su concepción y diseño. Es preciso remarcar la intención de analizar la instalación con la complejidad que nos la encontramos habitualmente, es decir, distribuida heterogéneamente en el territorio y constituida por espacios deportivos, complementarios y auxiliares.
La fundamentación teórica ha aportado la revisión de conceptos alrededor del espacio deportivo y que hacen referencia a la evolución histórica, la concepción urbanística y de planificación territorial, y la vertiente sociológica. Posteriormente, y entrando en la fundamentación metodológica, se ha realizado una investigación aplicada en la que los conceptos recogidos y revisados en el marco teórico han sido trasladados a la realidad concreta de los espacios deportivos de tenis, y a Cataluña. Para desarrollar esta parte, se han realizado propuestas de análisis geográfico y territorial, buscando los motivos de la heterogeneidad en la distribución actual de pistas de tenis y determinando el déficit territorial a través de la aplicación de los instrumentos existentes de planificación.
El uso de estas herramientas ha facilitado la revisión de parámetros descriptivos y clasificatorios de las instalaciones deportivas, y ha hecho posible la determinación de aquellos parámetros que son definibles desde el diseño y aplicables en el caso de las pistas de tenis. Este ha sido el punto de inicio para la elaboración de un instrumento de observación y estudio del espacio deportivo concreto (pista de tenis) según la forma organizativa que suele encontrarse en nuestro país (clubes).
A través de la aplicación sobre una muestra representativa de clubes se han buscado aquellos valores del modelo de análisis que han hecho posible, por un lado acercarse a la comprensión del objeto de estudio, y por otro concretar, con la interrelación de sus indicadores, los valores que proporcionan mayor idoneidad en cuanto al diseño de cada nivel de observación.
In this Doctoral Thesis, research has been conducted on tennis club facilities in Catalonia, with the aim of determining some design guidelines. Given the peculiarity of this type of sports facility, which due to its non-multisport character has been left out of the Xarxa Bàsica (Basic Network) specified and studied by the Generalitat de Catalunya, then we believe it is necessary to begin this study and provide some considerations for their conception and design. It is important to point out that we intend to study these facilities with the complexity with which we usually find them, that is to say, with a heterogeneous distribution in the territory and made up of sports, complementary and auxiliary spaces.
The theoretical base has provided a review of concepts surrounding the sports space and their historical evolution, their urban planning and the sociological aspects. Later, and going into the methodological foundations, applied research has been carried out because the concepts, collected and reviewed in the theoretical framework have been applied in the specific reality of the tennis courts, and in Catalonia. To carry out this part, we have developed proposals for geographical and territorial analysis, searching for the reasons for the current heterogeneous distribution of tennis courts and determining territorial deficits through the implementation of existing planning tools.
The use of these tools has facilitated the review of the descriptive and classifying parameters of sports facilities and it has allowed us to determine which of these parameters are definable from design and to be applied in the case of tennis courts. This was the starting point for the creation of an instrument to observe and study specific sports spaces (tennis courts) in the organisational reality that we normally find in our country (clubs).
Applying this to a representative sample of clubs, we search for the values of the analysis model which on the one hand make possible the approach to understanding the object of study, and on the other hand, to know, with the interrelation of its indicators, the values that provide greater suitability for the design in each level of observation.

Abstract:

Du jeu de société dans les salons mondains au début du XXe siècle au sport couru des années 1932 et 1933, ce jeu de balle casse une représentation réductrice et vestimentaire de la mode. Le ping-pong, qui est à l’origine une simple boîte de jeu, connaît deux forts engouements au cours de la première moitié du XXe siècle. En 1902, la mode est au divertissement de salon prétexte à la distinction sociale. Prenant place après les dîners de la Haute bourgeoisie, la droiture du corps est de rigueur. Le jeu respecte un code de galanterie qui en fait un jeu lent. Sa mode s’estompe dès 1903 lorsque le jeu se démocratise à la petite et moyenne bourgeoisies. Vivotant en tant que jeu de salon anodin, le ping-pong réapparaîtcomme une nouveauté en 1932 et 1933. Il est décrit comme un spectacle sportif à l’image de ses champions, de leurs prouesses techniques et des efforts physiques. Il prend également la forme d’une mode populaire en gonflant les rangs du sport ouvrier. Cette reconnaissance sportive dans les représentations sociales est effective quelques années après soninstitutionnalisation. Discours monolithique, la mode cache et relance aussi d’autres vogues. Une réminiscence bourgeoise en fait un jeu prisé des lieux de villégiature. Il se développe également au travers des cafés. L’apogée passée, le ping-pong « sport » perd des effectifs dans les fédérations au milieu des années 1930. Son image sportive chancelle. Elle s’explique par la place difficilement mesurable du jeu informel qui contente les pratiquants. Ce divertissement est alors autant perçu comme un jeu de détente qu’il constitue une manière informelle de faire du sport en dehors des institutions
From the board game in the worldly salons in the beginning of the 20th century to the sought-after sport in 1932 and 1933, this ball game breaks a reductive representation of fashion, mostly about clothing. Ping-pong, which is originally a simple game box, knows two major popular movements during the first half of the 20th century. In 1902, the trend is about salon entertainment, a pretext for social distinction. Taking place after diners in the wealthy bourgeoisie, straightness of the body is required. This game respects the gallantry code, which makes is a slow game. Its popularity is the upper class fades from 1903 when the game knows a democratisation in the petty bourgeoisie and the middle class. Eking out as a trivialsalon game, ping-pong reappears as a novelty in 1932 and 1933. It is described as a sporting show magnified by its champions, their technical feats and physical efforts. It also gains in popularity as it enters the habits of the working class. This sporty recognition in social representations is effective a few years after its institutionalisation. Monolithic vision, fashionalso hides and revives other tendencies. A bourgeois reminiscence makes it a popular game in the holiday destinations. It also expands in the coffee shops. Once passed its height, pingpong as a « sport » loses members in the federations in the middle of the 1930s. Its sporty image falters. This phenomenom explains itself by the hardly mesurable place of the informalgame, which satisfies the players. This entertainment is perceived as a relaxing game, as an informal way to practice sport out of the institutions

Abstract:

Background: Joint injuries are a complex matter. Due to the low blood flow to the tendons and ligaments, they take months or even years to heal; some fail to heal. This can be devastating for the elite athlete as well as for the labour worker or everyday person. Today, the devices that can detect an upcoming inflammation or injury, cost 15 000 US dollars and more. A cheaper technology would increase the access. This project is investigating the possibility to detect an upcoming inflammation through measuring the local skin temperature. Method: A model of an arm was built in Comsol Multiphysics, where a tennis elbow (lateral epicondylitis) was simulated through local temperature increase. Clinical tests were pursued on two healthy subjects, in order to gain knowledge on how the skin temperature behaves on healthy subjects. Results: At an internal temperature increase in the LE of 0.25 K, a temperature difference on the skin of 0.18 K was detected in the model. The clinical tests on healthy subjects indicated a correlation between the temperatures on and around the elbow joint. Discussion: The model results does not include any error sources, such as deviation in room temperature and factors affecting the subject´s body temperature, such as time of day, eating and exercising routines. The clinical tests show a pattern of the temperature distribution on and around the elbow joint, in healthy subjects. The fact that a pattern is present, is a presumption enabling to find deviations, caused by upcoming inflammation. Conclusion: The model is indicating that a local temperature increase in the LE is detectable at the skin surface. The clinical test indicates that the noise in the temperature data of a healthy person, is small enough to enable to detect a local temperature deviation. At a local skin temperature increase of more than 0.5 K, the results are indicating that the deviation is detectable. Analysing the model data, 0.5 K in skin temperature increase would mean a local temperature increase at the LE of approximately 0.7 K. This is before the stage of inflammation according to literature, which occurs at an increase of 1.5 to 2.2 K. Further studies would be interesting to make, in purpose of developing an affordable device that can detect if an inflammation is about to occur, and thereby enable the subject to stop the course. A prototype should be developed in order to make tests on more subjects. The equine industry is also a target group – the prototype may therefore be developed to fit both humans and horses.
Bakgrund: Ledskador är komplicerade. På grund av det låga blodflödet till senor och ligament, tar de månader eller år att läka; visa skador läker aldrig helt. Det här kan vara förödande för såväl elitatleter som arbetande och gemene man. Tekniker idag som kan detektera uppkommande inflammation eller skada, kostar 15 000 US dollar och mer. En billigare teknik skulle ha en större tillgänglighet. Det här projektet undersöker möjligheten att detektera en uppkommande inflammation genom att mäta den lokala skintemperaturen. Metod: En modell av en arm byggdes i Comsol Multiphysics, där en tennisarmbåge (lateral epikondylit) simulerades genom en lokal temperaturökning. Kliniska tester utfördes på två friska subjekt, för att skapa en bil av hur skintemperaturen varierar på friska personer. Resultat: Vid en inner temperaturökning om 0,25 K i LE, uppmättes en temperaturökning på huden om 0,18 K i modellen. De kliniska testerna på friska subjekt indikerade att en korrelation finns mellan temperaturerna på och runt armbågsleden. Diskussion: Resultat från modellen saknar felkällor, som exempelvis variation av rumstemperatur och andra faktorer som påverkar subjektets kroppstemperatur, som tid på dagen, mat- och träningsrutiner.De kliniska testerna uppvisar ett mönster av temperaturdistributionen hos friska subjekt på och runt armbågsleden. Att ett mönster finns, banar väg för att hitta avvikelser, som orsakas av uppkommande inflammation. Slutsats: Modellen indikerar att en lokal temperaturökning i LE är mätbar på huden. Det kliniska testet indikerar att bruset i temperaturdistributionen hos ett friskt subjekt, är litet nog för att möjliggöra detektion av en lokal temperaturavvikelse. Vid en lokal ökning av hudtemperatur med mer än 0,5 K, indikerar resultaten att avvikelsen är detekterbar. Vid analys av modellresultaten, innebär 0,5 K hudtemperatursökning en temperaturökningi LE om ungefär 0,7 K. Det är innan inflammation har brutit ut, som sker vid en ökning om 1,5 till 2,2 K. Vidare studier är intresssant att göra, i ändamål att utveckla en prisvärd produkt som kan detektera om en inflammation är på väg, och därigenom göra det möjligt för subjektet att stoppa förloppet. En prototyp behöver utvecklas för att kunna utföra tester på fler subjekt. Utöver människor, är hästindustrin en målgrupp – prototypen bör därför utvecklas för att passa båda grupperna.

Abstract:

Bakgrund: Agility är en egenskap som är avgörande för tennisspelares prestation. Det är således en egenskap som regelbundet bör tränas och utvärderas. Till detta projekt presenteras ett nyutvecklat och tennisspecifikt test som kan användas för att utvärdera tennisspelares reaktiva agilityförmåga. Syftet med studien var att utvärdera testets reliabilitet och validitet för att fastställa dess övergripande kvalitet. Ett andra syfte var att undersöka vilka fysiska egenskaper som korrelerade med prestationen på agilitytestet. Metod: Deltagare till studien var 18 tennisspelare (9 flickor och 9 pojkar; ålder 14.5 ± 1.5) med erfarenhet av matchspel på regional samt nationell nivå. Under ett testtillfälle på deltagarnas respektive tennisklubb genomfördes kroppsmätningar, fysiska tester samt agilitytester med en reaktiv komponent (RAG: reactive agility) och utan en reaktiv komponent (CODS: change of direction speed). Resultaten visade på en hög absolut reliabilitet (CV%: 2.69–4.28%) samt hög relativ reliabilitet (ICC:0.802–0.943). Fysiska egenskaper som korrelerade med agilityförmåga var spänst, sprintsnabbhet samt reaktiv styrka. Konklusion: Slutsatsen som kan dras är att det nyutvecklade tennisspecifika agilitytestet är ett reliabelt test som tennisspelare kan använda för att utvärdera sin agilityförmåga men där validiteten inte gick att uttala sig om i några mätbara termer och mer forskning är nödvändig.
Background: Agility is an important ability in tennis and should be trained and evaluated on a regular basis. In this project a newly developed tennis specific reactive agility test is presented. Aim: The aim of the study was to evaluate the reliability and validity of the agility test. A second aim was to analyze correlations between agility performance and physical abilities. Method: The sample consisted of 18 tennis players (9 males and 9 females; age 14.5 ± 1.5) who competed at regional and national level. The variables comprised body dimensions, sprint speed, jump height measures, single leg balance, change of direction speed (CODS) and reactive agility (RAG). Results: The results showed a high absolute reliability (CV%: 2.69–4.28%) and high relative reliability (ICC:0.802–0.943). Physical abilities that correlated with agility performance was jump height, sprint speed and reactive strength. Conclusion: The conclusion is that the newly developed reactive agility test is reliable and can be used by tennis players to evaluate agility. The test´s validity is not possible to determine, and more studies are needed.

Abstract:

De nos jours, la plupart des fabriquants de chaussures proposent des chaussures pour les jeunes joueurs de tennis qui sont des modèles réduits de celles des adultes. Cependant, les enfants ne sont pas des adultes-miniatures et ont des besoins spécifiques. Entre 8 et 12 ans, les enfants sont sujets à des poussées de croissance qui diminuent la flexibilité du membre inférieur et augmentent les forces de tension sur les sites d’insertions des tendons sur les os. De plus, la pratique du tennis à haute intensité, avec la répétition d’accélérations et décélérations, place d’importantes forces de tension au niveau de l’insertion du tendon d’Achille sur le calcaneus et d’importantes forces de compression sous le calcaneus. La combinaison de ces 2 facteurs augmente le risque de subir l’une des principales blessures de sursollicitaton chez les enfants : la maladie de Sever. Par conséquent, l’objectif de ce travail de thèse était de définir les caractéristiques d’un chaussant adapté au joueur de tennis enfant en terme de volume chaussant confortable et de limitation des blessures. Premièrement, une chaussette équipée de capteurs de pressions textiles a été conçue et la fiabilité de sa mesure a été validée. Ensuite, cet outil innovant a été utilisé afin de corréler la mesure de pression et la perception du confort sur 8 zones du pied, permettant ainsi de déterminer le volume intérieur de la chaussure optimal pour le joueur de tennis enfant. Deuxièmement, les effets aigus du drop de la chaussure sur la biomécanique des joueurs de tennis enfants ont été examinés et il a été montré que la réduction de 12 mm à 6 mm permettait de réduire les forces de réaction du sol et donc potentiellement les blessures liées à l’impact. Enfin, l’influence à long-terme de la réduction du drop de la chaussure sur la biomécanique et les douleurs au talon reportées par les jeunes joueurs de tennis a été investiguée. La réduction progressive du drop de la chaussure a induit un changement de patron de pose du pied, arrière vers avant-pied, pour la moitié des participants et a permis de supprimer leurs douleurs au talon. De futures études sont nécessaires pour examiner les adaptations structurelles du membre inférieur liées à l’utilisation de chaussures partiellement minimalistes
Nowadays, most of tennis footwear manufacturers propose children tennis shoes that are scaled-down from adult shoes. However, children are not adult-miniature and have specific needs. Between 8 and 12 years old, children experience growth spurts that decrease the lower limb flexibility and increase the tensile forces on tendons insertion sites onto bones. In addition, the practice of tennis in high-intensity, with the repetition of accelerations and decelerations, places high tensile forces at the Achilles tendon insertion site onto the calcaneus and large compressive forces under the calcaneus. The combination of these 2 factors increase the risk to experience one of the main overuse injuries in children: Sever’s disease. Therefore, the aim of this thesis work was to define the features of a suitable footwear for children tennis players in terms of fitting comfort and limitation of injuries. Firstly, a sock equipped with textile pressure sensors was designed and its measurement reliability was validated. Then, this innovative device was used to correlate pressure measurement and comfort perception on 8 foot locations, allowing to determine the optimal inner-shoe volume for children tennis players. Secondly, the acute effects of shoe drop on the biomechanics of children tennis players were examined and it was shown that reducing from 12 mm to 6 mm allowed to reduce ground reaction forces and thus potentially impact-related injuries. Finally, the long-term influence of shoe drop reduction on the biomechanics and heel pain reported by children tennis players was investigated. The gradual reduction in shoe drop induced a switch from a rear- to forefoot strike pattern in half of the participants and allowed to remove heel pain for them. Future studies are needed to examine the lower-limb structural adaptations linked to the use of partial minimalist shoes

Abstract:

Im Leistungssport wird Techniktraining täglich geplant und bewertet. Gerade die Änderungen in Regeln oder Technikentwicklungen machen Tischtennis zu einem interessanten Anwendungsfeld, wie ein Techniktraining verbessert werden kann. Der Fokus der vorliegenden Arbeit lag nicht nur auf den einzelnen Techniken, sondern ebenfalls darauf wie Übergänge zwischen den Techniken selbst optimiert werden können. Dazu wurde eine Diagnostik für die Techniken und Übergänge (Tischtennis Technikwechsel Leistungsdiagnostik) entwickelt, geprüft und verbessert. Aus den Ergebnissen der Diagnostik wurde eine Intervention der Techniken konzipiert (Phase I), die anschließend selbst- und fremdevaluiert wurde (Phase II). Die Erfahrungen der Intervention der Techniken und deren Evaluation wurden benutzt, um in einer Phase III eine zielgerichtete Trainingsmaßnahme zur Optimierung der Technikübergänge zu gestalten und zu evaluieren. Die Verbesserungen der Interventionsstichprobe gegenüber einer ebenfalls trainierenden Evaluationsstichprobe in kinematischen Analysen der Bewegungen und Trefferleistungen bestätigten die Hypothesen zu einer verbesserten Erreichung der Sollwertvorstellung. Trainingswettkämpfe sowie kurz- und langfristige videobasierte Wettkampfanalysen kamen zu dem Ergebnis, dass die Trainingseffekte auch die Wettkampfleistungen langfristig beeinflussen. Über die konkreten Fragestellungen des Forschungsprojektes hinaus konnten das theoretische Verständnis für sensomotorische Kontrollprozesse bei schnellen Bewegungen sowie methodologische Konsequenzen von langfristigen Evaluationsstudien erarbeitet werden. Ein Praxisteil mit Empfehlungen für die Planung von konkreten Trainingsinhalten schließt die Arbeit ab.
In high level sports is the training of techniques is an everyday event. Table tennis seems an appropriate game based on recent rule changes and developments in techniques, to evaluate how to improve technical training. The focus of this work lies on the training of techniques itself as well as the training of transitions between techniques. To test that a diagnostic (table tennis performance diagnostic for technique transitions) was developed and evaluated. The results from the diagnostic lead to conceptualize an intervention and its evaluation of techniques (phase 1) that was evaluated by inside- group and outside-group evaluators (phase 2). The experience with this intervention and evaluation was used in phase 3 to development trainings and evaluations for the transitions between techniques. The improved performance of the trainings group was superior to an evaluation group with the same training amount in respect of kinematical changes of the movements as well as with accuracy of the ball locations in respect to the assumed changes. Analyses of training competitions as well as videobased evaluations of short-term and long-term performances in real competitions demonstrated that these changes influence positively the overall performance. In addition to these results, the work helped to understand sensorimotor control processes of fast movements and methodological issues of long-term evaluation studies in high level sports. Finally consequences of this research were build in proposed training sessions.

Abstract:

Im Rahmen zweier Studien im Leistungssport werden die Effekte bewusster und unbewusster Faktoren auf implizite und explizite Motive untersucht. Es kann die Distinktheit der Vorhersagebereiche impliziter und expliziter Motivdiagnostik repliziert werden. Dabei wird aufgezeigt, dass die handlungsführenden Effekte impliziter und expliziter Motive jeweils exklusiv durch unbewusste Impulskontrolle und bewusste Selbststeuerungskompetenzen moderiert werden. Allein implizite Prozesse (implizite Motive, Impulskontrolle) besitzen prognostischen Wert für sportliches Leisten in Situationen die unbewusst verarbeitet werden. Explizite Prozesse (explizite Motive, bewusste Selbststeuerung) hingegen sagen sportliches Leisten in bewusst verarbeiteten Situationen des sportlichen Wettkampfs vorher. Die differentielle Prognostizität direkter und indirekter Motivdiagnostik in der Sportpsychologie kann durch die Berücksichtigung adäquater Faktoren verbessert werden. Aufgrund der Ergebnisse dieser Arbeit ist bei der Auswahl adäquater Persönlichkeitsvariablen darauf zu achten, dass das zu prognostizierende Kriterium und die Erhebungsmethodik bezüglich ihres Grades an bewusster Bearbeitung miteinander übereinstimmen.
The effects of conscious and unconscious factors on implicit and explicit motives were examined in the context of two studies. The distinct array of prediction by implicit and explicit motive diagnostic can be replicated. Though it was possible to provide evidence for the exclusive moderation of implicit motives by unconscious activity inhibition while explicit motives were moderated by conscious skills of self-regulation. Only the implicit processes (implicit motives and activity inhibition) proof a value to predicting human activity in situations coped without consciousness. In contrast only explicit processes (explicit motives and conscious skills of self-regulation) can predict the outcome of behaviour in situations coped with consciousness. The results of that paper can improve the differential prediction of direct and indirect motive diagnostic by regarding the adequate moderator factors. Further investigations will have the ability to improve the value of motivational predictors if they consider, that the level of consciousness is consistent within the situation of ascertainment the motivational predictor and the situation the criteria is imposed.

For tennis video analysis, the technology of player detection and tracking is a very important issue. We can obtain the important features such as the location of the court, and the position, the trajectory and the velocity of players, etc. By these features, the semantics of tennis video can be further extracted. The necessary processing is to separate the foreground (the players) and background (the court), then the algorithm of player detection and tracking can be developed accordingly. In this thesis, we employ the Edge Detection to eliminate the noise, then we exploit the method “Kalman-Filter based player tracking” to tracking the up-court players, moreover correcting the trajectory of player to correct the interference of up-court player trajectory. We developed a more robust, accuracy, automatic event analyze system for tennis video. We extract all events of one GAME from tennis video sequences, and analyze the features of all events. We use the relative location of players to define events in a video game. Simulation results show that the new method can effectively identify the event in a tennis game video.

Nowadays, Technological advance facilitates monitoring of human life for themselves through a set of sensors embedded in a smartphone. We can utilize these sensors for health care, monitoring the elderly health, sports expert and entertainment. In many previous investigations, they try to perform accelerometer data for off-line recognition, but in this thesis, we try to propose the use of a activity recognition of tennis activities in real-time. The values of the 3-axis accelerometer sensor are tested in a real time in a way by sending these values to the server for processing. A software application is designed to show and evaluate the best model for designing the tennis activities recognition. The results shows that the SVM algorithm using one second with window size of 20 samples achieve highest accuracy until 96.25%. To measure the level of classification accuracy in the training data, the 10 fold cross validation is performed automatically on feature matrices using machine learning algorithm which is provided by WEKA software.

In recent years, due to the popularity of sport activities, general masses or sport professionals can utilize various video recording tools to record, produce, pick and fetch useful information or interesting programs. Sport video analyses have attracted attention gradually. Sport video has an inherent structure as defined in rules of the game and field production. In addition, some highlights in the sports game such as homerun in the baseball, shot in the football and ace in the tennis make the sport video more suitable for further investigation than other types of video such as the films and news. Tennis sport video is selected as the primary domain due to its content richness and popularity. With an ongoing rapid growth of sport video information, there is an emerging demand for a sophisticated tennis content-based video indexing system. However, current video indexing solutions are still immature and lack of any standard. Artificial intelligent strategies are proposed to combine characteristics in the audio and image domain and knowledge to find the highlight. Moreover, broadcasted sports videos generally last several hours with many redundant advertisements and the key segments are not easy to find. The proposed model can be extended to different application domains, such as tennis acrobatics training, exciting news editing, and program preview in the future. Based on the experimental results, both the average of precision and recall rates are higher than 89%. This verifies that the proposed model is effective in extracting the highlights of tennis sport.
