Full textAbstract:
Track and field is a traditional instructional unit often taught in secondary physical education settings due to its history, variety of events, and potential for student interest. This article provides an approach to teaching this unit using the sport education model (SEM) of instruction, which has traditionally been presented as a model for team and dual sports. The application of the SEM to this individual sport provides teachers with an opportunity to provide their students with an authentic, engaging and festive environment in which to learn a sport that has been around for centuries.

"Strength Gains: Block Vs DUP Weight-Training among Track and Field Athletes." Digital Commons @ East Tennessee State University, 2012. https://dc.etsu.edu/etsu-works/4132.
Full textAbstract:
Recently, the comparison of “periodized” strength training methods has been a focus of both exercise and sport science. Daily undulating periodization (DUP), using daily alterations in repetitions, has been developed and touted as a superior method of training, while block forms of programming for periodization have been questioned. Therefore, the purpose of this study is to compare block to DUP in Division I track and field athletes. Thirty-one athletes were assigned to either a 10-wk block or DUP training group in which sex, year, and event were matched. Over the course of the study, there were 4 testing sessions, which were used to evaluate a variety of strength characteristics. Although performance trends favored the block group for strength and rate of force development, no statistically significant differences were found between the 2 training groups. However, statistically different (P ≤ .05) values were found for estimated volume of work (volume load) and the amount of improvement per volume load between block and DUP groups. Based on calculated training efficiency scores, these data indicate that a block training model is more efficient than a DUP model in producing strength gains.

Full textAbstract:
The biggest question in astrophysics and cosmology today is identifying the composition of the Universe. Approximately 25% is thought to be comprised of dark matter, particles that lie outside of the standard model of particle physics and have such a low cross section that they have to date evaded detection despite the substantial indirect observational evidence. DRIFT-II is one of about two dozen experiments designed to directly detect dark matter in the laboratory. Dark matter particles, through an elastic nuclear recoil, should create ionisation tracks in the detector. A positive signal would be the identification of a number of dark matter events that have an anisotropic distribution of recoil directions peaked in the direction of solar motion. The work presented here is a detailed analysis of the data from the DRIFT-lIb experiment and includes event discrimination and techniques for two and three dimensional track reconstruction. The expected dark matter event rate given the latest experimental results is calculated for this particular experiment with a result of 8.6 . 10-3 events per kg·day. The lower energy resolution limit of the detector is measured as 1.23 keV for an electron recoil and 3.46 keV for a sulphur nucleus recoil. Simulations of the particle interactions expected in the detector are performed and applied to experimental data. A full analysis of the directional sensitivity of the detector is also presented. Finally, a dark matter exclusion limit is calculated from experimental data to be 6.9 10-2 pb for a WIMP mass of 100 GeV/c2

Thesis (MScSportSc)--Stellenbosch University, 2013.ENGLISH ABSTRACT: The purpose of this study was to compile a sport psychological skills profile of track and field athletes and to determine whether a purposefully-developed psychological-skills training (PST) programme would affect this profile and athletic performance. The study was conducted in two phases. During the first phase 143 student athletes completed sport psychological skills questionnaires before competing in the 2011 University Sport South Africa (USSA) Athletics Championship. The athletes’ perceived importance of psychological skills, psychologically preparedness, and need for psychological skills training were investigated. The athletes’ best performances at the championship were recorded and their IAAF performance points calculated. The majority of the athletes perceived PST as important. However, in contrast, a large percentage was uncertain about their need for PST programmes and, alarmingly, most of the athletes under-utilized the services of sport psychologists. This could possibly indicate a resistance to PST. Overall, the results revealed poor sport psychological skill levels. Only the achievement motivation and goal directedness dimensions showed satisfactory results. Effect sizes were used to compare the sport psychological skill levels of more and less successful athletes. This revealed significant differences between the respective groups. The within-group comparisons showed that the more successful sprinters outscored the less successful sprinters in the subscales of stress control and achievement motivation. Achievement motivation was the only aspect that differed significantly between the more and less successful middle and long-distance athletes. Among the jumpers, confidence and stress control distinguished between the top and bottom athletes. The more successful throwers recorded higher imagery and achievement motivation scores than the less successful throwers. The results from the first phase were used to develop a PST programme aimed at improving the sport psychological skill levels and performance of student track and field athletes. In Phase Two, athletes from Stellenbosch University were divided into an experimental (n = 24) and control group (n = 18). Both groups underwent pre and post-testing of the same psychological skills questionnaires used in the first phase, whilst their athletic performances were recorded on both occasions. The experimental group participated in a PST programme consisting of seven sessions which covered the following topics: achievement motivation, goal-directedness, managing somatic anxiety, managing cognitive anxiety, self-confidence, concentration, and imagery. In addition to these sessions daily activities and assignments were completed in a workbook. The effectiveness of the PST programme in improving the athletes’ sport psychological skills levels is evident from the improvements observed in nine of the eleven subscales among the experimental group opposed to four skills among the control group. Inexplicably, the control group’s athletic performance improved significantly more than that of the experimental group. Further research into the role and effectiveness of PST in track and field is recommended.
AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om ’n sportsielkundige vaardigheidsprofiel vir baan- en veldatlete saam te stel en om te bepaal tot watter mate ’n sportsielkundige vaardigheidsprogram (SVP) hierdie profiel en atletiekprestasie sal beïnvloed. Die navorsing het uit twee fases bestaan. Gedurende fase een het 143 studente-atlete verskeie sportsielkundige vraelyste voltooi voor deelname aan die 2011 Suid-Afrikaanse Studente-Atletiekkampioenskappe (USSA). Die atlete se persepsie oor die belangrikheid van sielkundige vaardighede, sielkundige voorbereiding en behoefte aan onderrig in sielkundige vaardighede is ondersoek. Die atlete se beste vertonings tydens die kampioenskappe is gemonitor en hul IAAF- prestasiepunte bereken. Die meerderheid van hierdie atlete het aangedui dat sportsielkundige vaardigheidsontwikkeling belangrik is, maar in teensteling hiermee het ’n groot persentasie aangedui dat hulle onseker is oor hul behoefte aan sportsielkundige vaardigheidsontwikkeling. Die bevinding dat die meerderheid van die atlete nie genoegsaam van sportsielkundige dienste gebruik maak nie, is kommerwekkend. Hierdie verskynsel kan op ’n weerstand teen sportsielkundige vaardigheids-ontwikkeling dui. In geheel het die sportsielkundige profiel van hierdie baan- en veldatlete swak vertoon, behalwe vir prestasiemotivering en doelgerigtheid wat bevredigende resultate opgelewer het. Effekgroottes is gebruik om die sportsielkundige vaardighede van minder en meer suksesvolle atlete met mekaar vergelyk. Dit het beduidende verskille tussen die groepe opgelewer. Die binnegroepvergelykings het getoon dat meer suksesvolle naellopers hoër tellings as minder suksesvolle naellopers in die volgende subskale behaal het: stresbeheer en prestasiemotivering. Prestasiemotivering was ook die enigste subskaal wat tussen meer en minder suksesvolle middel- en langafstandatlete kon onderskei. Selfvertroue en stresbeheer was twee aspekte wat tussen meer en minder suksesvolle springers gediskrimineer het. Prestasiemotivering en beelding was die enigste sportsielkundige dimensies wat tussen meer en minder suksesvolle gooiers kon onderskei. Die meer suksesvolle gooiers het beter vlakke met betrekking tot hierdie twee subskale getoon. Die resultate van die eerste fase is gebruik om ’n sportsielkundige intervensieprogram te ontwikkel waardeur sielkundige vaardighede en prestasie van tersiêre baan- en veldatlete verbeter kan word. In die tweede fase is atlete van die Stellenbosch Universiteit in ’n eksperimentele- (n = 24) en kontrolegroep (n = 18) verdeel. Beide groepe het dieselfde sportsielkundige vraelyste as in die eerste fase, voor en na afloop van die intervensieprogram, waaraan die eksperimentele groep meegedoen het, voltooi. Alle deelnemers se atletiekprestasies is voor en na afloop van die intervensieprogram genoteer. Die eksperimentele groep het aan die ontwikkelde sportsielkundige vaardigheidsprogram deelgeneem wat uit die volgende sewe sessies bestaan het: prestasiemotivering, doelgerigtheid, somatiese angsbeheer, kognitiewe angsbeheer, selfvertroue, konsentrasie en beelding. Hierdie sessies is deur daaglikse aktiwiteite aangevul en opdragte wat in ’n werkboek voltooi moes word. Die effektiwiteit van die program in die ontwikkeling van sielkundige vaardighede blyk duidelik uit die bevinding dat die eksperimentele groep betekenisvolle verbeteringe getoon het in nege uit elf sportsielkundige vaardighede teenoor die vier vaardighede wat by die kontrolegroep verbeter het. ’n Onverklaarbare bevinding was egter dat die kontrolegroep se atletiekprestasies betekenisvol meer verbeter het as die eksperimentele groep s’n. Verdere navorsing oor die rol en effektiwiteit van sportsielkundige vaardigheidsontwikkeling in atletiek word aanbeveel.

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2005.Includes bibliographical references (leaf 54).
The objective of this thesis is the design and implementation of a multi-axis force transducer to be integrated into a set of track and field starting blocks. The feedback from this transducer can be used by athletes and coaches to analyze race starts, with the intention of maximizing the runner's speed and power while decreasing wasted side loads and torques. This thesis describes the design of the transducer itself and the supporting infrastructure that connects it to an existing pair of track starting blocks. The transducer is tested in several field trials and generates a measurable voltage output that varies linearly with applied load and loading position. Data collected from the field trials is further analyzed to give insight into the starting mechanics of a collegiate sprinter.

Full textAbstract:
Track stiffness is the one of the most critical parameters of the track structure. Its evaluation is important to assess track quality, component performance, localised faults and optimise maintenance periods and activities. Keeping the track stiffness within acceptable range of values is connected with keeping the railway network in a satisfactorily performing condition, allowing thereby upgrade of its capacity (speed, load, intensity). Current railway standards are changing to define loading and stiffness requirements for improved ballasted and ballastless performance under high speed train traffic. In recent years various techniques have been used to measure track deflection which have been also used to validate numerical models to assess various problems within the railway network. Based on recent introduction of the Video Gauge for its application in the civil engineering industry this project provides the proof of effective applicability of this DIC (Digital image correlation) tool for the accurate assessment of track deflection and the calculation of track stiffness through its effective applicability in various track conditions for assessing the stiffness of various track forms including track irregularities where abrupt change in track stiffness occur such as transition zones and rail joints. Attention is given in validation of numerical modelling of the response of insulated rail joints under the passage of wheel load within the goal to improve track performance adjacent to rail joints and contribute to the sponsoring company s product offering. This project shows a means of improving the rail joint behaviour by using external structural reinforcement, and this is presented through numerical modelling validated by laboratory and field measurements. The structural response of insulated rail joints (IRJs) under the wheel vertical load passage is presented to enhance industry understanding of the effect of critical factors of IRJ response for various IRJ types that was served as a parametric FE model template for commercial studies for product optimisation.

Full textAbstract:
Thesis (MA (Political Science))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: The climate of the Great Lakes Region fostered desperate sources of insecurity which fed each other in a conflict-system which was also largely fuelled by the surrounding war economy. Consequently, the focus of this study was narrowed to providing only a descriptive analysis of the Democratic Republic of the Congo’s peace processes of 1998-2002. Subsequently, the surrounding climate served to aggravate the DRC’s ethnic cleavages and the conflict grew so complex that the issues could no longer be clearly divided. The motivation for conducting a study of this nature was that amidst the twenty-three failed attempts for peace, the conflict persisted with no signs of abating, which suggests that a historical and discourse analysis of the peace processes is justified. This study found that during these peace processes, far greater prominence was given to Track I diplomacy than to the unofficial Track II diplomacy. This was due to various limitations that existed. This distinction is fundamental because even though unofficial diplomacy has a different function to official diplomacy, their values are equal and more effective in a peace process when there is a collaborative effort between the two. This is called a Multi-Track approach (Diamond and McDonald, 1996). Thus this study proposes that by giving Track II diplomacy a greater prominence in a peace process, the Multi-Track approach would be fully utilized. It suggests that governmental, informal, and unofficial contact in civil society is fundamental in trust-building between parties in negotiation. Overall, there is value in providing a critical descriptive analysis of both Track I and Track II diplomatic initiatives that were undertaken during the 1998-2002 peace process, in order to expose the shortcomings. In doing so, this study presents the Multi-Track approach in order to emphasize its potential efficacy in addressing similar future cases of intractable conflict.
AFRIKAANSE OPSOMMING: Die omstandighede in die Groot Merestreek het onsekerheid gekweek, wat mekaar versterk het in die konteks van ’n konflik-sisteem wat ook deur die omliggende oorlog-ekonomie aangevuur was. Gevolglik is hierdie studie se fokus beperk tot ‘n beskrywende analise van die vredesprosesse wat tydens 1998-2002 op die tweede rebellie in die Demokratiese Republiek van die Kongo gevolg het. Die omstandighede in die omliggende omgewing het die DRK se etniese splitsings vererger, en die konflik het so kompleks geword dat daar nie meer duidelik tussen die verskillende geskilpunte onderskei kon word nie. Die motivering vir hierdie studie is dat daar te midde van die drie-en-twintig mislukte vredespogings geen teken was dat die konflik aan die afneem was nie, wat suggereer dat ’n historiese diskoers analise van die vredesproses geregverdig is. Hierdie studie het gevind dat daar gedurende hierdie vredesprosesse ’n veel meer prominente rol aan die amptelike Track I-diplomasie as aan die nie-amptelike Track II-diplomasie toegeken was, as gevolg van verskeie beperkinge wat bestaan het. Hierdie onderskeid is van kardinale belang; ten spyte van die feit dat nie-amptelike diplomasie ’n ander funksie as amptelike diplomasie vervul, dra dit ewe veel waarde en behoort vredesprosesse waar daar samewerking tussen die twee inisiatiewe plaasvind dus meer effektief te wees. Hierdie redenasie word ’n Multi-Track benadering genoem. Hierdie studie stel voor dat die Multi- Track benadering meer effektief geïmplementeer kan word deurdat daar aan Track IIdiplomasie ’n meer prominente rol in die vredesproses toegeken word; dit stel dus ook voor dat regeringskontak, informele en nie-amptelike kontak tussen gewone burgers van kardinale belang in die bou van vetroue tussen bemiddelingspartye is. Daar lê dus waarde daarin om ’n krities-beskrywende analise van beide Track I- en Track II inisiatiewe wat tydens die 1998-2002 vredesprosesse onderneem is weer te gee, ten einde die tekortkominge daarvan uit te wys. Op hierdie manier hou hierdie studie die Multi-Track benadering voor om uiteindelik die potensiële bruikbaarheid van hierdie benadering in soortgelyke toekomstige gevalle van konflik te beklemtoon.

Full textAbstract:
Abstract Aim: The aim of this study was to examine junior and first year senior athletes’ experiences and perceived effects of flotation-REST, including both the immediate response and experiences over time. Method: Semi-structured interviews were conducted with six elite track and field athletes (five female and one male), aged 17-23 years, who were purposefully sampled and had used flotation-REST two to six times. They were each interviewed on two occasions; once directly following a floating session and later a second interview concerning the overall experience. The interview transcripts were analyzed using Interpretative Phenomenological Analysis (Smith, 1996). Results: From the analysis four themes emerged: Meaning of Flotation-REST, Experiences during Flotation-REST, Perceived Effects of Flotation-REST, and Views on Flotation-REST. Flotation-REST became a learning opportunity concerning relaxation for all athletes and three of them reported that it raised their awareness of the importance of relaxation and psychological skills training. For five athletes the floating sessions also became a breather in the daily life. The floating sessions were perceived as pleasant and relaxing. Three athletes experienced a lot of thoughts in the tank and five of them fell asleep at least twice. After flotation-REST five athletes reported experiencing less stress and an overall increase in well-being as well as feeling calmer and more energized for one or two days, although they were physically tired at practice immediately following a floating session. Being in a better mood and placing fewer demands on themselves as well as feeling more optimistic and present were also mentioned as perceived effects. The results showed more and longer-lasting psychological effects than physiological. The sixth athlete did not experience any special effects, nor did he experience stress in his daily life and sport performance, as opposed to the others. Conclusions: The study shows the potential of flotation-REST as a technique for health promotion and also as a method for stress management. Further, as the results revealed raised awareness, flotation-REST could be valuable together with other psychological skills training techniques, mindfulness and the physical training. However, considering the differences in the athletes’ perceived effects of flotation-REST, it indicates the importance of further research on the topic.

The aim of this study was to examine how athletes and coaches, in Sweden and Portugal, perceive and experience success and failure in relation to sport. Moreover, study if there were cultural differences in coping. The main objectives of the study consisted of examining differences based on culture and coaches vs. athletes in the following research questions; how athletes and coaches define, react and cope with success and failure, how they perceive consequences and how coaches help athletes to cope with success and failure. Fifteen (n=15) individual semi structured interviews was carried out with ten (n=10) Swedish and five (n=5) Portuguese sportsmen. An interview guide based on the objectives of the study was developed. 1226 raw data units were identified and categorised using categorization, tagging and regrouping of relevant concepts. The results are discussed according to several stress-coping theories. Moreover, the result showed some differences based on both culture and on coaches vs. athletes. Furthermore success was mainly defined as reaching goals and failure as performance related mistakes. Reactions on both success and failure were mainly emotional. Negative consequences of both success and failure were most common and problem- focused coping were adopted to cope with those situations. The coaches supported the athletes by adopting emotion- and problem-focused coping.

Full textAbstract:
Although the “self” has generally been conceptualized as relatively stable in sport-specific research, events such as deselection, injury, and career termination have been found to negatively affect athletes’ levels of identification with the athlete role. Additionally, there has been limited research regarding competitive failure and its ability to negatively affect athletes’ levels of identification with the athlete role. The purpose of the present investigation was to provide additional evidence regarding the influence poor competitive seasons have on the malleability of athletes’ self-identity. Athletes were followed throughout the course of their season to determine whether athletes who encountered a poor competitive season reported lowered levels of athletic identity. Specifically, male and female NCAA Division I track and field athletes completed pre-indoor, post-indoor, and post-outdoor assessments of athletic identity. Contrary to previous research, the current study’s results indicated no identifiable relationship between male and female athletes’ season performance satisfaction and their level of post-indoor and post-outdoor athletic identity. Thus, the greatest predictor of athletes’ post-season level of athletic identity was their pre-season level of athletic identity, regardless of season performance. Given these results, future research should assess self-esteem as well as other potential coping strategies athletes might use in order to gain a better understanding of the effect encountering a poor competitive season may have on athletes’ self-identity.

Adequate stores of iron are necessary for optimal athletic performance and severe iron depletion resulting in iron-deficiency anemia may depress performance. This is important for athletes, particularly females, to address because they can be prone to iron deficiency anemia. This review examines research data that has shown oral iron supplementation in doses of at least 45 mg ferrous sulfate or 106 mg ferrous fumarate improves iron status and may improve measures of athletic performance. It is recommended that female athletes most at risk of iron deficiency be screened at the beginning of and during training seasons using ferritin measures. Appropriate dietary and/or supplementation recommendations should be made to those with compromised iron status.

Problem: Track and field athletes, along with cross-country athletes have multiple and back to back seasons, creating overuse injuries. Stress fractures or stress reactions to the bone are the overuse injuries focused on in this study and literature review. There is a lack of information in the literature regarding stress reactions. Purpose: The goal of the study is to understand more information about stress reactions to bone and possibly increase the knowledge of health care professionals. Methods: Three case studies were examined through pre-existing medical chart notes and athletic trainer's notes regarding the stress reactions. A literature review was also performed to provide further information about stress fractures and stress reactions. Conclusions: There are multiple risk factors for stress injuries. All three of the athletes in the case studies are female, which is found to be a risk factor. Many risk factors need more studies to provide support. Magnetic Resonance Imaging (MRI) was obtained in all three case studies where there was found to be a stress reaction. These three females also had a recent increase in activity level and had similar symptoms to each other and what is found in the literature.

Objectives of the study consist of examining how athletes and coaches define, react and cope with success and failure, how they perceive consequences and how coaches help athletes to cope with success and failure. Ten (n=10) individual semi structured interviews was carried out with seven (n=7) elite athletes and three (n=3) coaches in track and field. An interview guide based on the objectives of the study was developed. 385 raw data
units were identified. These were categorised according to the objectives. The analysis showed that athletes and coaches defined success as achieving goals and a typical reaction to success was to feel happy. A typical consequence that follows success was increased self
confidence and athletes cope with this by setting new goals. The analysis of coaches showed that coaches create an understanding for the athletes, what they want and what they need. Failure was most frequently defined as injury. The most common reaction to failure was increased negative thinking and athletes coped with that by “clenching the fist”. Coaches help athletes to cope with failure by adapting the training. Development was considered to be a
significant consequence of failure.

"Relationship of Peak Isometric Strength to Rate of Force Development Among Collegiate Track and Field Athletes." Digital Commons @ East Tennessee State University, 2008. https://dc.etsu.edu/etsu-works/4096.
Full textAbstract:
Explosive strength, a function of rate of force development (RFD), is a primary determinant for the amount of peak force that can be produced in critical sport performance time periods ( e.g. foot contact time). Evidence indicates that maximum strength and RFD are correlated. However, the characteristics of this relationship are not well established among athletes. This study examined the relationship of peak isometric force (IPF) and RFD from a mid-thigh pull, among male and female track and field athletes. Athletes were 12 sprinters (S), 10 jumpers (JP) and 12 cross-country runners (XC). Force-time curve analysis was conducted for each (2 trials) isometric pull and averaged for analyses. IPF and RFD from 0 - 200 ms were determined from appropriate curves. IPFs were normalized using an allometric (IPFa) scaling equation: absolute force/ (body mass (kg)0.67). ICCs were previously shown to be > 0.9. Relationships were established with Pearson's r; statistical differences with a Bonferroni adjusted t-Test. IPF, IPFa and RFD were greater in males than females for S and JP but not for XC. IPF, IPFa and RFD were greater for S and JP compared to XC. Similar relationships of IPF to RFD were noted among groups S(r = 0.85), JP (r = 0.87), XC (r = 0.88). Among males, n = 19, the relationship ofIPF to RFD was r = 0.89 and was somewhat higher compared to females, n = 15, (r = 0.78). Overall (n = 34) relationship between IPF and RFD was r = 0.90. These data indicate a strong relationship between maximum strength and "explosiveness" that is independent.

Full textAbstract:
The process of strength–power training and the subsequent adaptation is a multi-factorial process. These factors range from the genetics and morphological characteristics of the athlete to how a coach selects, orders, and doses exercises and loading patterns. Consequently, adaptation from these training factors may largely relate to the mode of delivery, in other words, programming tactics. There is strong evidence that the manner and phases in which training is presented to the athlete can make a profound difference in performance outcome. This discussion deals primarily with block periodization concepts and associated methods of programming for strength–power training within track and field.

Full textAbstract:
Correct formation during starting block execution is important for injury prevention and obtaining maximum velocity during the sprint. Researchers in applied behavior analysis have evaluated several procedures to improve performance in sports such as gymnastics, football, and, golf. A promising method to improve sports performance is expert modeling plus video feedback. However, there is little research on this method and it has yet to be evaluated with sprinters in track and field. Therefore, the purpose of this study was to evaluate the effectiveness of expert modeling and video feedback to improve form during block starts with track and field sprinters. Results revealed marked improvement from baseline to intervention across all four participants that was maintained at follow-up.

Full textAbstract:
This thesis addresses enhancement technologies and their ethical permissibility through a contextual, bottom up approach based on case studies. The first chapter presents various definitions of 'enhancement', arguments for and against, and discusses the therapy/enhancement distinction. The second chapter discusses applying genetic technologies from bendh to bedside, analysing: the objections to reprogenetics grounded in 'eugenics'; and, how pre-implantation genetic diagnosis (PGD) and other embryonic genetic screening techniques, as well as genetic tests sold online directly-to-the-consumer (DTC) to measure children's athletic potential raise a conflict between parental reproductive freedom and children's rights to an open future and capacity for self-determination. Chapter 3 turns to how genetic technologies are translated directly from the molecular medicine laboratory to "track & field," analysing: the scientific and regulatory context of gene enhancement, and on which basis it is classified as doping; how the International Olympic Committee and the International Association for Athletics Federation incorrectly consider hyperandrogenism an unfair advantage; and, the World Anti Doping Agency Code and its current revisions. Chapter 4 discusses enhancements in a democratic society, and addresses the neglected issue of justifying enhancement research (ER). I propose: a model in which cognitive enhancements, currently prescribed under a 'disease' model, could instead be prescribed under an 'enhancement' model; and, a possible justification for ER that translates the ethical criteria justifying clinical research to the enhancement context. I then consider possible changes society would need to implement to accommodate ER. The last chapter attempts to advance the discussion of enhancement by shifting the debate from ethics to policymaking, arguing for a deliberative democracy approach. Throughout, I adopt a casuistic approach to ethics, deploying tools from consequentialist, principled and virtue ethics. I try to break the stalemate between enhancement's proponents and opponents, and discuss the ethical permissibility of technologies in ways that could inform policymaking.

Athletic career is very limited. Athletes one day must encounter to retirement eventually. The researcher myself has years of experience in athletics. Through in-depth interviews with track and field athletes and collection of relevant information and documents, the factors of their retirement are learned. The research also covered the course of education, training regiments and career planning of these track and field athletes. The results are: First, track and field athletes may do so through sports skills education, but not the final factor to consider decommissioning; secondly, to improve our athletes' lack of career planning, which led to a lack of a second expertise. So the (lack of) second expertise is an important factor in weighing upon these athletes’ retirement. When there is a career-switching opportunity relying upon their second expertise, they will seize it and alter their original career planning; finally, the lack of established professionalized track and field competitions in Taiwan causes insecurity of these athletes and eventually lead them into early retirement.

High Energy Accelerator Research Organization (KEK) is located in Tsukuba city, Japan. An accelerator KEKB and a detector Belle are located in a tunnel inside KEK. Belle experiment is operated for ~11 years. It is stopped for upgrade in 2010 July. The upgrade accelerator is named SuperKEKB, and the upgrade detector is named Belle-II. The Fu Jen Catholic University high energy lab joins the Central Drift Chamber(CDC) trigger system group. The main purpose of CDC chamber is to measure the trajectory and momentum of charged particles. CDC is an important tool to identify charged particles. This thesis describes two dimensional track finding method in CDC trigger system. We use the Hough transform algorithm to find the trajectory equation of charged particle in Hough plane and translate back to CDC x-y plane. We simulate a single charged particle which pass through the CDC chamber. We classify cluster cases and optimize the mesh size for a better cluster cell gathering. We use the trajectory function to trace back the momentum of the input single charged particle. The results between the input and output values are consistent.

Since ancient times, the mentoring is the most widely used system when teaching technical ability in all sorts of trades. The role of the master is not only teaching professional knowledge and skill, but also in charge of apprentices’ morality. Therefore, the role of master can become a teacher, father and friend.The major objective of this research is to study the relationship between female track and field coaches and athletes. This research adopts narrative inquiry as the primary research method and uses in-depth interviewing as the main method of data collection. The participants in this research is a female track and field coaches teaching over twenty years,black coaches and her student ,hippo. The research results have shown that hippo and black coaches in some chance, set up a as well friend as well mentor of relationship. When hippo ended the identity of athlete, the mentoring relationship collapsed. However, depend on each other deep emotion ,communication and understanding, they established a sisterhood relationship. Someday every athlete will leave their coaches , someone may leave with resentment or thanksgiving. The relationship among coaches and athletes, sometimes as enemies, sometimes like a friend, sometimes like a lover, sometimes more like a family. This emotion should be difficult to forget. Development of mentoring relationship finally test the wisdom of coaches and players to each other.

ABSTRACT
Title: Relative Energy Deficiency in Female Collegiate Track & Field Athletes.
Background: Energy deficiency and its consequences have long been studied in female athletes because of it’s potential for increasing risks of illness and injury. Sustaining an energy deficient diet while training and during competition may result in muscle loss and reduction in performance. Studies suggest that athletes competing in sports focusing on appearance or a lean physique are at high risk for energy deficiency. In 2014, the IOC developed the concept of ‘Relative Energy Deficiency in Sport’ (RED-S) to include new components not previously included in the Female Athlete Triad. A study has not yet been completed applying the RED-S paradigm in collegiate track and field athletes.
Objective: The purpose of this study was to examine the prevalence of RED-S in female collegiate track and field athletes. It was hypothesized that the majority of collegiate track and field athletes experience RED-S. It was also hypothesized that a greater percentage of distance runners experience RED-S than other track and field athletes, including throwers, jumpers, and sprinters. The components of RED-S assessed were menstrual function, bone health, and energy expenditure.
Methods: This study was a descriptive cross-sectional study, obtaining data through the use of a questionnaire and a relative energy expenditure index on a population of 12 female collegiate track and field athletes. Data were obtained through the use of a LEAF-Q questionnaire, a three-day food and exercise recall, and body composition analysis.
Results: The 12 athletes were a combination of distance runners (n=5), throwers (n=2), and sprinters (n=5). Average subject characteristics were: age (20.6 ±1. 44 years), height (165.6 ±7.5cm), weight (63.58 ± 16.97kg), and body fat percentage (20.9± 7.2). Average energy intake over three days was 2146 kcal (±627), and the average predicted energy expenditure was 2380 kcal (±458). Average hours spent in a catabolic (52.8 ± 24.0), highly catabolic (37.5 ± 25.0), anabolic (19.2 ± 24.0), and highly anabolic state (12.4 ± 21.0). Subjects were in a negative energy balance state the majority of the days analyzed, and 75% of the population had at least one day of dietary recall below 45 kcal/kg FFM/day. Spearman’s rho analysis found a significant inverse correlation between Day 1 hours spent in optimal energy balance (± 400 kcal) and body fat percent (p=0.024, rs= -0.643), and significant positive correlation between Day 1 hours spent in optimal energy balance (± 400 kcal) and fat free mass percentage (p=0.03, rs=0.625). Spearman’s rho analysis also found an inverse correlation between Day 1 hours spent in an energy deficit (s= -0.626), and a positive correlation between Day 1 hours spent in an energy deficit and body fat percentage (p=0.026, rs=0.636). Seven out of twelve participants scored ≥ 8 on the LEAF-Q putting them at risk for RED-S.
Conclusion: The study highlights the misleading effect of averaging multiple days of dietary recall on energy balance. When participant’s dietary recalls were assessed day by day the majority of hours were spent in a catabolic state, however when the three days of the recall were averaged the severity of the hours spent in a catabolic state lessened. The associations in this study are consistent with previous studies evaluating the relationships between energy balance deficits and body composition, indicating that longer duration spent in an energy deficit is associated with lower lean and higher fat mass. The findings from the LEAF-Q show that 58% of participants were at risk for RED-S, and half of all participants had or were experiencing menstrual dysfunction.

International M.Sc. in Performance Analysis of Sport (IMPAS)The aim of this study was to investigate changes in training load, neuromuscular readiness, perceptual fatigue and competition performance in junior track and field athletes during an outdoor season. To fulfil this purpose, data from six athletes (age 17.5 ± 1.7 years; height 172.6 ± 9.9cm; body mass 62.1 ± 6.4kg) were collected from both training sessions and athletics competitions during a 16-week period, divided into a preparation (week 1 to 8) and a competitive period (week 9 to 16). Training load was computed through training diaries, the countermovement jump and the repeated jump test were executed on a weekly-basis, and perceptual fatigue measures were collected using a wellness questionnaire. At the end, a hierarchical cluster analysis was conducted to identify similarities and differences between the two periods. The results showed a substantial reduction in training load during the competitive phase. The countermovement jump and sleep quantity were associated with the best competition performance of the competitive season and indicated a positive development during the outdoor season. The others variables showed different patterns between athletes. This outcomes can be used as framework for implementing athlete monitoring system with young athletes involved in track and field sprint-power events.

This study is aimed to investigate the type of track and field running track material, the application of current status and future trends. Interviews and document analysis were the methods used to discover the following findings： 1.The formation and development Of track and field runway material usage. Track and field runway surface materials was used to overcome natural factors of climate and to create a fair competition venue; its historical background factors were： Firstly, during The ancient Egyptian times in 2600 BC and The ancient Greece in 776 BC, running was a behavior to worship or to celebrate, therefore, they ran on mud. Secondly, during 146 BC Roman times to 1400 AD Renaissance movement, people were running on natural sediment and grass to exercise. Thirdly, cinder material were used during the European Industrial Revolution era, and red clay (brick clay) material were used in 1928 Amsterdam Olympic Games. Finally, synthetic plastic material were used during 1968 Mexico Olympics. At the same time, International Olympic Committee designated it as the official material of the Olympic track and field runway. 2.Planning and design of track and field runway surface Synthetic track and field runway surface material can be divided into three，First, laying system for on-site polyurethane material, the surface layer is made on scene from modulation into 4 type. Full plastic, particles, composite and breathable. Second, The prefabricated membrane of synthetic rubber from the surface layer is made of factory prefabricated, emphasizing the complete reunification of the properties and thickness of surface layer. Third, Prefabricated membrane PP / PE artificial grass. The grass of the surface layer are free to adjust the length on the use of the venues so it is more diverse. 3.Current status and trends of the development of track and field runway material Currently, the use of track and field runway material can be divided into two. First, the use of PU runway surface material is now more commonly used in track and field. Second, synthetic rubber material is widely used in a variety of international track and field events. Development trends can be divided into two parts. The growing popularity of synthetic plastic track and the environmental friendly red clay. Key words：Track and field,Runway material

Abstract On the red-studded track tells the story of a track-and-field trainer at school who went from establishing a running team of only six students to leading the team in winning national track-and-field champion, and to finally stepping onto the world stage as a coach representing the country. This research focuses on Mr. Chang, Sheng-Hui, who has devoted himself to track-and-field for decades. It aims to investigate the faith and global perspective Mr. Chang holds toward this sport, and to acknowledge how he fulfills his philosophy through physical education. The author has discovered that, through interviews and close observations, Mr. Chang led his students to finding their suitable talents with his expertise, to setting new records constantly, and finally to becoming parts of the world stage. “Indebted reciprocation” is the creed of Mr. Chang that will be discussed throughout the current paper. His selfless contributions to students are seen beyond races for golds but stretch afar to the field, in which stories of joys and pains intertwine with that of insights and disciplines. Hence, the author hopes to convey, through this written study, the deep understandings of Mr. Chang’s philosophy to all on the same land.

Full textAbstract:
Tese de doutoramento em Engenharia Civil (área do conhecimento em Geotecnia)The analysis of ballasted railway structures still demands many improvements towards preceding an accurate estimate of its global behavior, i.e, towards reproducing the real performance of the materials and the structure. Furthermore, in the design process, ultimate/serviceability limit states and life cycle costs should be attended. As a result, a wide range of research works are being introduced. This work contributes to the improvement of these processes throughout laboratory and numerical experiments aiming to investigate (with particular emphasis) on the dynamic stress field analysis, particularly the characteristic stress paths followed by granular elements below a typical track structure under the passage of a High-Speed Train (HST). The experimental laboratory work allowed, by means of a high-precision cyclic triaxial stress-path apparatus, the definition of the elastic domain of a foundation soil. The numerical experiments were carried out using an elastic frequency domain model and an elastoplastic time domain model, validated with in situ data obtained by vibration measurements in a HST railway line. These numerical models were used to analyze the influence of stiffness of the foundation (elastic domain) and structural layers of railway granular materials (elastic or elastoplastic domains) in the stress field, clearly showing that the stress response is a function of the selected constitutive law. Furthermore, the linear elastic assumption for the foundation soil was found to be questionable, suggesting that further investigation is required.
A análise de estruturas ferroviárias balastradas exige melhorias que a tornem capaz de reproduzir o comportamento global, i.e., que seja possível a reprodução do desempenho real dos materiais e da estrutura. Além disso, no processo de dimensionamento, os estados limite de utilização/últimos e os custos de manutenção devem ser considerados. Como resultado, uma ampla gama de trabalhos de investigação está actualmente em curso. Este estudo contribui para a melhoria destes processos, através de experiências laboratoriais e numéricas que focam com particular ênfase o campo dinâmico de tensões induzido nas camadas granulares das estruturas ferroviárias, quando submetidas à passagem de um comboio de alta velocidade. O trabalho experimental laboratorial permitiu, por meio de um sistema triaxial cíclico de precisão capaz de aplicar qualquer trajectória de tensões, a definição do domínio elástico de um solo de fundação. Os trabalhos experimentais numéricos foram realizados utilizando um modelo elástico no domínio da frequência e um modelo elasto-plástico no domínio do tempo, validados com medições in situ de vibrações numa linha ferroviária de alta velocidade. Estes modelos numéricos foram usados para analisar a influência da rigidez da fundação (domínio elástico) e das camadas granulares estruturais da via ferroviária (domínios elástico ou elasto-plástico) no campo de tensões, mostrando claramente que a resposta é função da lei constitutiva seleccionada. Além disso, a assumpção de comportamento elástico linear para o solo de fundação é questionável, requerendo-se investigação adicional.

In the sports team, coach occupies a pivotal position, so the coach''s leading behavior decisively influenced the team to be successful or not. So, this study tries to investigate the relationship between the leading behavior of track and field coaches and leadership effectiveness for track and field team members in Taichung junior high school, and then make specific recommendations. The study subjects were the junior high school students in Taichung who participated in the school''s track and field team in 102 academic year, 294 questionnaires were collected out of 300. The results show that most members of junior high school track and field team are male and second grade. The weekly training hours are mostly 11 to 15 hours. And most of them participated in training for 1-2 years. The perception ranking for coaches’ leading behavior was as follow: “Training and leading behavior” was the highest; “dominating behavior” was the lowest. The perception ranking for coaches’ leadership effectiveness was as follow: “The cohesion” was the highest, and “the performance” was the lowest. There were significant differences among some dimensions in terms of coaches’ leading behaviors and leadership effectiveness on different background variables. The results indicated that there is a significant positive correlation in the relationship of the coaches’ leading behaviors and the leadership effectiveness, except the dimension“dominating behavior”. Based on results of this study, track and field coaches in junior high school should do more training and leading behavior to replace the traditional dominating behavior. They have to absorb more relevant expertise and techniques, and do team teaching with other coaches to help athletes focus on this movement.
