Dissertations / Theses on the topic 'Tenis'

Full Tenis Perú nace en la Universidad de Lima en el curso de Proyecto de Especialidad el cual les permite a los alumnos llevar a cabo algún proyecto que tengan en mente, además de asesoramiento en el proceso a realizar. Nos dimos cuenta que la situación del tenis necesitaba apoyo. La idea nace con el propósito de crear una web integral ya que existía la carencia de una plataforma que esté al alcance de todos y sea completa; que incluya contenido tanto de tenis nacional como internacional, que brinde todo tipo de consejos relacionados a este deporte, información sobre academias nacionales y, sobre todo, que reconozca a los tenistas más destacados para así brindarles apoyo, darles valor y de cierta manera promover este deporte.

This diploma thesis deals with designing and manipulating a robot for training table tennis. Robot's mechanical construction is based on aluminium profiles supported by various standardized assembly units, such as rotating bearings, plain bearings, threaded rods... The front-end part of the robot, which requires better deformation property and lighter weight, was made from ABS material using 3D rapid prototyping technology. The design of the robot allows its body to rotate around three axises. Thanks to the high dynamical ability, robot can be set to throw balls to various places on the playing table, with different types of ball spin. Balls will be shot out by two rubber wheels, which are attached to two electrical DC motors. By driving the speed of the two motors, we can control the speed of the ball, as well as speed of its spin. All robot's activities are driven by an embedded system designed using microcontroller ATMega128. A firmware for controlling robot's function was writen and flashed into the microcontroller. End-users might communicate with the robot via a system of buttons and a text LCD display. The built robot was tested and it has shown its ability to throw balls to 6 different places of the playing table, at different speeds, with different types of ball spin, and different spin speed, according to the parameters set by user.

Chile a nivel mundial ha sabido destacar y desarrollarse para insertarse con gran éxito en el mundo, especialmente en cuanto a lo económico, instalándose como una de las economías emergentes más sólidas y prósperas de la región; logrando importantes acuerdos comerciales con los bloques comerciales más grandes del mundo, (tratados de libre comercio con la Unión Europea, Estados Unidos, Corea, en vías de estudio con China, la participación de Chile en MERCOSUR, APEC, entre otros). Y de esta manera participar cada vez de un mundo más globalizado. Personalmente, siempre me han gustado los deportes, por el esfuerzo, la superación y la pasión que estos generan. Por otro lado está la arquitectura de la cual siempre me he sorprendido por su potencial para activar y generar EVENTOS, (entendiendo eventos como actividades espontáneas). Eventos que difícilmente podemos controlar, a los cuales, creo sólo podemos programar y generar un soporte especial y mental, siendo imposible definir y acotar de antemano la envergadura, las emociones y todas las situaciones que ahí ocurrirán. La arquitectura en este caso y especialmente la arquitectura contemporánea, se asemeja a una plataforma que da soporte y proyección a los eventos.

El Estadio Nacional de Tenis nace por la adjudicación de Chile de los Juegos ODESUR, Santiago 2014. Su objetivo principal es entregar la infraestructura y equipamiento para llevar a cabo las distintas fases de las eliminatorias de la modalidad del Tenis. A partir de eso se proyecta un Conjunto Deportivo destinado para potenciar el tenis en nuestro país, esto se logra incorporando a la Federación de Tenis de Chile, organismo máximo del tenis en nuestro país. La presente memoria busca entregar el fundamento y marco de mi Proyecto de Titulación. En éste documento se encuentran las bases que me guiaron al momento de proyectar y diseñar el Estadio Nacional del Tenis + su conjunto. Está dividida en 6 Capítulos. Primeramente se presenta la elección del tema y su respectiva problemática. Posterior a ello se entregan los antecedentes necesarios para poder enfrentar y resolver la problemática identificada previamente. Para comenzar a proyectar concretamente se estudió el terreno, el capítulo de Lugaridad da a conocer el emplazamiento del proyecto. La idea arquitectónica y partido general, que nacen desde la etapa anterior, son presentados en el Capitulo 4: Proyecto, donde se encuentra la justificación de las decisiones tomadas como arquitecta aspirante. La memoria en si misma finaliza con el resultado del último proceso académico dentro de nuestra carrera, Planimetría e imágenes del proyecto, que son nuestro lenguaje, medio principal por el cual expresamos nuestro quehacer. Además se presenta la respectiva bibliografía y profesionales asesores que se consultaron para desarrollar el Estadio Nacional de Tenis.

Memoria para optar al título de periodista
Para poder hablar con conocimiento de causa sobre el desarrollo del tenis de menores en Chile fue necesario narrar el contexto de este deporte en el mundo y en el país. Preguntas como, ¿dónde se inventó el tenis? ¿Por qué llegó a Chile? ¿Quiénes lo jugaban en sus comienzos? ¿Cómo se organizaba y administraba la actividad?, entre otras, tienen respuestas justificadas en este trabajo. Por su parte, en esta investigación se estableció un marco legal del deporte en general por parte del Estado chileno, al igual que los beneficios que tiene este, y en específico el tenis, para la población. Por otro lado, también se examinó el funcionamiento de la Federación de Tenis de Chile (FTCH) a nivel administrativo, regional y económico. Esto último, en tanto, fue acuciosamente revisado a través de las opciones de financiamiento que el Estado, por medio del Instituto Nacional del Deporte (IND), le entregó al tenis gracias a los documentos solicitados vía ley de transparencia. Asimismo, y de manera inédita, se consultó, recabó y analizó la infraestructura tenística con la que cuenta Chile por intermedio de solicitud de transparencia a las 345 5 comunas del país. Además, esta información fue complementada y corroborada con profesores de tenis y departamentos de deportes y Direcciones de Desarrollo Comunitarios (Dideco) de municipalidades. En cuanto al tenis de menores como tal, en el trabajo se distinguió y dividió en tres aristas de investigación la progresión que un niño o niña puede tener el deporte: masificación (llegada), desarrollo y alto rendimiento. En esta línea, cada una fue abordada desde un punto de vista histórico, haciendo un repaso cronológico desde los inicios del tenis en Chile hasta la actualidad. Una de las mayores trabas para la realización de este reportaje fue la desconexión existente entre los organismos y entidades representantes del tenis, liderados por una federación que poco y nada puede aportar en términos de información histórica y estadística. Sin embargo, se revisó y recopiló todo el material bibliográfico de fuentes documentales ubicado en: bibliotecas, tales como la Biblioteca Nacional de Chile y la biblioteca del Comité Olímpico de Chile; así como libros, revistas, artículos de prensa, estatutos; y en internet, es decir, tesis, memorias, notas de prensa, sitios webs sobre tenis, leyes, etc. De igual forma, para fines de esta investigación se realizaron 40 entrevistas, en su gran mayoría presenciales y en caso de lejanía geográfica se usaron herramientas como llamadas telefónicas y correos electrónicos. Las fuentes consultadas fueron seleccionadas en base a sus antecedentes ligados al tenis y pertinencia con los temas a desarrollar, recibiendo una buena acogida por parte de una amplia diversidad de entrevistados/as como dirigentes, exdirigentes, entrenadores/as, árbitros, jugadores/as, exjugadores/as, organizadores/as de torneos y periodistas. Por último, para la redacción de este reportaje se consideró relevante hacer la distinción entre hombres y mujeres a través de sus artículos y terminaciones gramaticales respectivas. Plasmar la diferencia de sexo a través del lenguaje ayuda a construir un relato 6 más igualitario en cuanto a las perspectivas de los hombres y las mujeres, sobre todo considerando la contienda desigual que existe en todos los estamentos del tenis.

Resumo: A síndrome de burnout, conhecida como síndrome do esgotamento físico, psíquico e emocional, acomete pessoas de diversas áreas profissionais. No esporte, é comum constatar tanto profissionais quanto atletas em esgotamento. A síndrome de burnout é o eixo central desta pesquisa realizada com técnicos de tênis de campo sobre sua percepção com atletas acometidos pela síndrome. Para o presente estudo adotou-se a tradução do termo burnout para esgotamento. O objetivo do estudo foi pesquisar as opiniões dos técnicos de tênis de campo, a respeito da síndrome de burnout em atletas infanto-juvenis e profissionais na referida modalidade. Utilizou-se como método a pesquisa qualitativa, optando pela análise de conteúdo para a categorização dos dados obtidos com os questionários. Para isso, foi elaborado um questionário com onze questões fechadas (caracterização dos sujeitos) e nove questões abertas. Trinta e quatro técnicos foram contatados e apenas dois deles não participaram do estudo. Após o contato prévio com os sujeitos, marcou-se um encontro para aplicação dos questionários. De posse dos questionários, após uma análise qualitativa, pode ser verificado que 81% dos técnicos já tiveram atletas que apresentaram sinais de esgotamento. Um outro dado obtido com as respostas foi que sinais fisiológicos para o esgotamento tiveram 96% das menções dos técnicos. Foram vinte e quatro menções para a categoria Treinos como precursores para a síndrome de burnout no tênis de campo. É importante que técnicos de tênis de campo conheçam o fenômeno da síndrome de burnout para que sejam capazes de orientar seus atletas, garantindo-lhes uma boa qualidade de vida em suas carreiras esportivas
Abstract: The syndrome of burnout, known as syndrome of the physical, psychic and emotional exhaustion, acomete people of diverse professional areas. In the sport, it is common to evidence in such a way professional how much athlete in exhaustion. Burnout syndrome is the central axel from this research conducted with Tennis coaches about their perception over athletes with this syndrome. The adopted translation for burnout within this study was ¿esgotamento¿. The main goal of this study was researching tennis coaches opinions about burnout syndrome in juveniles athletes and professionals within the same sports modality. Qualitative method of research was used, where the option for content analyzes was made for categorizing data obtained from questionnaires. To be used as an instrument it was elaborated a questionnaire made by 11 closed items (individual characterization) and nine open items. There were contacted thirty four (34) coaches, and only two (2) of them did not participate on the study. After the previous contact a meeting was scheduled for answering the questionnaire. It was verified that 81% of the coaches have already had athletes presenting signs of burnout. Another data obtained from the answers was that physiological signs for acknowledging the syndrome had 96% of the times mentioned by the coaches. Twenty four times ¿Practicing¿ was quoted as precursor for Tennis burnout syndrome. Results lead to a conclusion that it is very important for tennis coaches to recognize the burnout syndrome to be always able to guide their athletes

Resumo: O presente estudo teve os seguintes objetivos: caracterizar as demandas fisiológicas de diferentes rotinas de treinamento e, avaliar o efeito da suplementação de citrato de sódio sobre o desempenho de habilidades específicas do Tênis após uma simulação de partida. Dez jogadores de Tênis juvenis, do sexo masculino (17,0 ± 1,2 anos; estatura: 176,7 ± 5,2 cm; peso: 68,4 ± 7,9 kg; gordura corporal: 11,7 ± 1,4%) participaram dos estudos. No primeiro estudo foram realizadas quatro rotinas de treinamento, cada qual com seis pontos. As rotinas se diferiram entre si pelo número de rebatidas por ponto (duas, quatro, sete e dez rebatidas por ponto). Foram avaliados frequência cardíaca (FC), percepção subjetiva de esforço (PSE) e concentração de lactato ([La]) após o primeiro, terceiro e sexto ponto de cada rotina. O segundo estudo consistiu na suplementação de citrato de sódio (0,5 g.kg-1 de peso) ou placebo - NaCl (0,1 g.kg-1 de peso). Após 120 minutos da ingestão do suplemento, foram realizados testes de habilidades específicas no Tênis (Loughborough Tennis Skill Test ¿ LTST e Repeated Sprint Ability Shuttle Test ¿ RSA) antes e após a simulação de uma partida de 60 minutos. Observou-se que todos os parâmetros avaliados no primeiro estudo (FC, PSE e [La]) aumentaram progressivamente durante as rotinas de treinamento, à medida que se aumentava o número de rebatidas por ponto, indicando que rotinas de treinamento com sete e dez rebatidas por ponto induziram respostas maiores associadas ao nível de estresse do que observado nas rotinas mais curtas. No segundo estudo observou-se aumento significante (p<0,05) da [HCO3-] e do excesso de base no grupo suplementado com citrato de sódio comparado ao placebo. Após a simulação de partida houve aumento da [La] e de pH no grupo suplementado com citrato de sódio ([La]: 5,46 mmol.L-1; pH: 7,48) comparado ao grupo placebo ([La]: 2,28 mmol.L-1; pH: 7,34). A capacidade de sprints repetidos avaliada pelo RSA não apresentou diferença (p>0,05) entre os testes pré e pós simulação de partida. Apesar do total de golpes desenvolvidos pelos jogadores não apresentarem diferença significante (p>0,05) antes e após a simulação de partida, observou-se declínio (p<0,05) na consistência dos golpes para o grupo placebo (pré: 53,5%; pós: 40,4%) quando comparado ao grupo suplementado com citrato de sódio (pré: 50,2%; pós: 58,5%). Portanto, sugere-se que a suplementação de citrato de sódio pode prevenir o declínio do desempenho das habilidades específicas do Tênis, após uma simulação de partida
Abstract: This study had the following objectives: To characterize the physiological demands of different training routines and evaluate the effect of sodium citrate supplementation on the performance of specific tennis skills after a simulated match. Ten young male tennis players (17,0 ± 1,2 years old; height: 176,7 ± 5,2 cm; weight: 68,4 ± 7,9 kg; body fat: 11,7 ± 1,4%) participated in the studies. In the first study, four training routines were performed, each with six points. The routines differed according to the number of hits per point (two, four, seven and ten hits per point). Heart rate (HR), rating of perceived exertion (RPE) and blood lactate concentration ([La]) were assessed after the first, third and sixth points of each routine. The second study consisted of supplementing with sodium citrate (0,5 g.kg-1 body weight) or placebo - NaCl (0,1 g.kg-1 wt). One-hundred and twenty minutes after taking the supplement, tests were performed for specific tennis skills (Loughborough Tennis Skill Test - LTST and Repeated Sprint Ability Test Shuttle - RSA) before and after simulating a match of 60 minutes. All parameters evaluated in the first study (HR, RPE and [La]) were found to increase progressively during training routines, as the number of hits per point increased, indicating that training routines with seven and ten hits per point were associated with higher levels of stress than for the shorter routines. The second study demonstrated a significant increase (p <0,05) in [HCO3-] and base excess in the group supplemented with sodium citrate, compared with placebo. After the match simulation, increases were observed in [La] and pH in the group supplemented with sodium citrate ([La]: 5,46 mmol.L-1; pH: 7,4), compared to the placebo group ([La]: 2,28 mmol.L-1; pH: 7,34). The ability to repeat sprints, as evaluated by RSA, did not differ (p > 0,05) between the pre and post match simulation. Although the total number of hits performed by the players was not significantly different (p>0,05) before and after starting the simulation, we observed a decrease (p<0,05) in the consistency of the hits in the placebo group (pre: 53,5%; post: 40,4%), when compared to the group supplemented with sodium citrate (pre: 50,2%; post: 58,5%). Therefore, we suggest that supplementation of sodium citrate may prevent the decline in performance of specific tennis skills after a simulated match

Resumo: O propósito deste trabalho foi de realizar um estudo eletromiográfico para comparar a atividade elétrica entre tenistas e não tenistas nos músculos trapézio (porção superior), deltóide (porção anterior), deltóide (porção posterior), bíceps do braço (cabeça longa), peitoral maior (porção esterna1) e grande dorsal nos movimentos básicos do tênis, que são o forehand, backhand e saque. Cada movimento foi dividido em três fases: início, aceleração e término. Vinte voluntários (10 tenistas e 10 não tenistas), com idade entre 20 e 30 anos, destros, foram analisados através de um eletromiógrafo (VIKING TI) de 8 canais utilizando-se de mini- eletrodos de superficie tipo Beckman, onde cada voluntário realizou três vezes o mesmo movimento. A análise dos resultados foi efetuada através de software específico, o SISDIN, que forneceu os dados numéricos em RMS (Raiz Quadrada da Média), expressos em microvolts (p. V). Foi utilizado um metrônomo para indicar com precisão o tempo exato das três fases de cada movimento. O método estatístico utilizado foi a Análise de Variância (ANOVA). Os resultados mostraram que independentemente dos movimentos e das fases os tenistas apresentaram atividade elétrica maior do que os não tenistas nos músculos trapézio (porção superior), deltóide (porção posterior), bíceps do braço (cabeça longa), peitoral maior (porção esternal) e grande dorsal. Não houve diferença estatisticamente significativa entre os tenistas e não tenistas no músculo deltóide (porção anterior). O músculo que apresentou maior atividade elétrica foi o músculo trapézio (porção superior) e o músculo que apresentou menor atividade elétrica foi o músculo grande dorsal. O músculo que apresentou a maior diferença de atividade elétrica entre tenistas e não tenistas foi o músculo peitoral maior (porção esternal). A maior atividade elétrica apresentada pelos tenistas em relação aos não tenistas, é devido à melhor adaptação e maior intensidade aplicada aos movimentos realizados
Abstract: The purpose of this work was to study by electromyography, the electric activity between tennis players and non-tennis players in the trapezius (upper fibers), pectoralis major (sternocostal portion), deltoide (anterior and.posterior portion), biceps branchii (long head) and teres major muscles in the basic movements of tennis which are: the forehand, the backhand and the serve. Each movement was divided in three phases: beginning, acceleration and end. Twenty young volunteers (10 tennis players and 10 non-tennis players), aged 20 to 30 years dextrous, were studied by using a electromyographyc equipment with eight channels. The electromyographyc signals were captured by surface minielectrodes (Beckman Type), where each volunteer has performed the same movement three times. The signals were analysed by a specific software the SISDIN, which supplied the numerical data in RMS (Root Mean Square), expressed in microvolts (J.! V). A was used to indicate the accuracy of the exact time of the three phases of each movement. The statistic method used was the variance analysis (ANOVA). The results revealed that regardless of the movements and the phases, the tennis players have presented greater electric activity than the non-tennis players in the trapezius (upper fibers), pectoralis major (stemocostal portion), deltoide (anterior and posterior portion), bíceps branchii (long head) and teres major muscles. There was no significant statistic difference between the tennis players and non-tennis players in the muscle deltoide (anterior portion). The muscle which has presented the greater difference in the electric activity was the muscle trapezius (upper fibers), and the muscle which has presented the lowest electric activity was the teres major. The muscle which has presented the greater difference in the electric activity between tennis players and non-tennis players was the muscle pectoralis major (stemocostal portion). The greater electric activity presented by tennis players, compared to the non-tennis players is due to the best adaptation and greater intensity applied to the movements

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.

Resumo: Após verificarmos a não existência de dados sobre os procedimentos de ensino do tênis de campo para portadores de comprometimento mental, pensamos na hipótese de um trabalho específico com alunos portadores da Síndrome de Down. O objetivo desta pesquisa foi proporcionar a aprendizagem desta modalidade através de procedimentos adequados e adaptados, respeitando as características individuais dessa população. Participam desta pesquisa 8 sujeitos cujas idades variam entre 9 e 15 anos, divididos em grupos de acordo com seu grau de desenvolvimento e faixa etária, tendo aulas uma vez por semana, com duração de 45 minutos cada. Como procedimento metodológico utilizamos a análise de tarefas, as observações assistemática e participativa, bem como filmagens, fotos e diário de campo, tendo em vista subsídios que complementem a avaliação do trabalho. Podemos concluir, após a sugestão dos procedimentos, que os alunos podem aprender os fundamentos básicos da modalidade, bem como apresentar melhoras em alguns itens relativos ao comportamento adaptativo tais como, autonomia, aptidões sociais, participação comunitária, saúde e segurança e o lazer. A partir deste estudo, novos procedimentos poderão ser investigados, visando favorecer a aprendizagem desta modalidade ainda pouco acessível às minorias
Abstract: After verifying the lack of data regarding procedures for teaching field tennis to mentally-handicapped people, we haveplanned a specific work with students with Down's syndrome. The purpose of the present research was to provide a learning of this sport through adequate adapted procedures which take into account the special characteristics of the subjects. This research was carried out with 8 subjects ages 9 to 15, divided into groups according to their degree of development and age. They all had 45-minute classes once a week. As methodology procedure we have used task analysis, asystematic and participative observations, as well as videotapes, photographs and notes to gather data to complement the evaluation of the work. After the suggestion of the procedures, we can conclude that the students are capable of learnng the basics of the sport, as well as improving some aspects regarding adaptive behavior such as autonomy, social aptitude, community participation, health and safety, and leisure. This research may be used as a starting point to the investigation of new procedures, aiming at supporting the learning of tennis, which is still somewhat inaccessible to minorities

Resumo: O presente estudo, caracterizado como um delineamento descritivo correlacional, teve como objetivo verificar o grau de associacao entre a Percepcao de Competencia Pessoal de tenistas da Categoria 12 Anos Masculino, as posicoes por eles ocupadas no Ranking Brasileiro, a Experiencia Geral e o Aproveitamento Esportivo dos atletas. A amostra selecionada de forma voluntaria nao probabilistica foi constituida por 29 atletas de tenis da Categoria 12 Anos Masculino, participantes do Ranking Brasileiro. Para a coleta de dados utilizou-se um Questionario de Anamnese, o Ranking Brasileiro, a Ficha Tecnica da Confederacao Brasileira de Tenis e a Escala de Percepcao de Competencia (EPC). Para a analise dos dados foi utilizado o teste de regressao linear simples, adotando-se como intervalo de confianca p.0.05. Os resultados revelaram uma correlacao positiva entre o Ranking e a PC Atletica, embora nao tenham permitido determinar a relacao entre a Percepcao de Competencia Pessoal dos tenistas com as posicoes por eles ocupadas no Ranking Brasileiro. Altas correlacoes foram encontradas entre o Ranking e o Aproveitamento Esportivo (p<0,01 e r=0,88) e entre o Ranking e a Experiencia Geral (p<0,01 e r=0,82). Com o presente estudo, pode-se concluir que os tenistas da Categoria 12M, independentemente das posicoes ocupadas no Ranking Brasileiro, apresentam uma alta PC Atletica e que a relacao entre o ranking, o aproveitamento esportivo e a experiencia geral dos atletas parece estar associada as regras estabelecidas pela CBT, que atribui pontos proporcionais as rodadas alcancadas pelos atletas, alem de premiar com pontos os jogadores que participam de torneios oficiais mesmo perdendo na primeira rodada.
Abstract: The purpose of this correlacional descriptive design research was to investigate the association of perceived competence of male tennis players; aged under 12 years old with their Brazilian fs ranking positions, their general experience and their success sport rate. The study fs sample was composed of 29 boys under 12 years old from national Brazilian Ranking. Were used as instruments the Perceived Competence Scale (Harter, 1985, adapted to Portuguese by Fiorese, 1993), the Brazilian Ranking, the player fs technical sheet of Brazilian Tennis Confederation (CBT) and a questionnaire made by author. All the variables were tested with normality test Kolmogorov-Smirnov and the variable general experience was also tested through bivariate normality test with all the others variables. Multiple regression and Linear regression was conduct with all variables and the adopted interval confidence was p.0,05. The results showed that athletic perceive competence and Ranking was significant but weak (p=0,44 and r=0,38) therefore the H1 could be partially accept. It was not possible to confirm that the players on the best positions of the Brazilian Ranking has better perceived competence than the players on the lower positions of the Brazilian ranking. The results showed also that tennis players under 12 has high perceived competence (3,17 }0,44). The high correlations between Ranking, success sport rate (p<0,01 e r=0,88), and their General Experience (p<0,01 e r=0,84), allowed to accept that these results are due the rules of Brazilian ranking imposed by CBT that give points not only for player who wins but also for the ones who loses in the first round of the officials tournaments.

Los antecedentes que a continuación se exponen, justifican este trabajo, cuyo objetivo es la elaboración de un plan de negocios para la instalación de un club de tenis en la comuna de La Reina. Este tema nace del interés de inversionistas que ya poseen un club deportivo en la comuna, de crear nuevas instalaciones, debido al sostenido crecimiento que han presentado las ocupaciones de canchas de tenis en los últimos 10 años, que se explica en parte por la creciente adhesión en este deporte, luego de los éxitos obtenidos en esa disciplina por sus exponentes de elite. Lo anterior, además, coincide con la oportunidad de arrendar un terreno a bajo costo, a un costado del parque Padre Hurtado, ex parque Intercomunal de La Reina. La metodología utilizada para el desarrollo del trabajo es la de plan de negocios, con especial énfasis en la investigación de mercado y el desarrollo del plan de marketing, elementos claves para una buena evaluación y posterior operación del negocio. Así, se realizó una estimación cuantitativa de la demanda por este servicio, la que se materializó en una encuesta practicada a residentes de las inmediaciones del club. A continuación se identificaron los elementos necesarios para poder caracterizarla. Para la determinación de la oferta, se utilizó la observación directa de la competencia, lo que permitió obtener su cuantificación y caracterización. Se estimó además una demanda para el club, planteado a partir de contrastar la demanda potencial estimada y contrastarla con la oferta disponible. Como parte del plan de negocios, se desarrollaron los diversos elementos que lo componen: marketing, recursos humanos, operaciones, ventas y finanzas. La evaluación indica que para el desarrollo del negocio es necesario invertir cerca de 140 millones de pesos. Con los flujos y proyecciones consideradas, se obtiene un VPN de 54 millones de pesos en un horizonte de planificación de 8 años con una tasa de descuento del 20%, La TIR para el proyecto es de 32,6%. Todo lo anterior indica que el proyecto es atractivo en las condiciones planteadas y estimadas.

Abstract: The general aim of this thesis was to apply the critical power model for the table tennis specific test as a procedure to estimate aerobic and anaerobic capacities. The study included thirty-two male table tennis players from five teams affiliated to the Brazilian Table Tennis Federation (CBTM). The thesis was divided into four experiments to: 1) Verify the physiological profile and characteristics of table tennis measured in official tournaments; 2) Compare maximal and submaximal physiological responses measured in the table tennis specific test with those measured on a cycloergometer, arm crank, and treadmill (conventional ergometers); 3) Investigate applying the Critical Power model to table tennis as an aerobic capacity predictor, verify the effects of exhaustion criteria (voluntary and technical exhaustion) and mathematical modeling of this parameter, and also to compare results from maximal and submaximal respiratory parameters measured during the specific incremental test; and 4) Correlate the curvature constant parameter (W') from the Power and time hyperbolic relationship, where W' was estimated using four mathematical models; and to correlate each W' estimated with maximal accumulated oxygen deficit (MAOD) and total anaerobic work at supramaximal intensities. Results showed that table tennis presented higher aerobic system predominance during a match, where the phosphagenic energy source was the main mechanism resynthesizing energy during effort periods. This was based on match duration, rally time, low blood lactate response, and sub-threshold heart rate response. Thus, knowing the table tennis physiological profile, experiments 2 and 3 investigated the application of aerobic and anaerobic procedures using specific and conventional ergometers. Experiment 2 revealed different maximal and submaximal physiological responses when comparing the specific test with results... (Complete abstract click electronic access below)

En el Capítulo 1 se hace una breve referencia al deporte profesional y un análisis de la situación actual de los tenistas en relación a la calificación jurídica de deportistas profesionales. Luego en el Capítulo 2 se presenta una descripción de los principales mecanismos de financiamiento del deporte en Chile, llegando finalmente al contrato de patrocinio o esponsorización. En el Capítulo 3, se realiza un análisis teórico-jurídico de esta figura contractual, dando cuenta de cuál es su realidad en el derecho comparado y en nuestro país. Posteriormente, en el Capítulo 4 se describe la estructura organizativa del tenis profesional, pasando desde el ámbito internacional al ámbito nacional. En el Capítulo 5 se contrasta la teoría con la aplicación práctica, a la luz de patrocinios celebrados entre tenistas y/o organizadores de torneos con las empresas patrocinadoras. Finalmente, se presentan las conclusiones

INTRODUCCIÓN. Un alto volumen de entrenamiento, en posiciones concretas y específicas al deporte, con acciones articulares repetitivas, podría generar adaptaciones en el sistema músculo-esquelético. En este sentido, varios estudios han valorado el morfotipo raquídeo en deportistas de diferentes disciplinas deportivas, encontrando adaptaciones específicas del morfotipo raquídeo al deporte practicado. No obstante, la influencia de la práctica del tenis no ha sido suficientemente analizada. Además, solo algún estudio ha analizado qué influencia tienen los entrenamientos realizados o la competición. OBJETIVO. Determinar la disposición sagital del raquis torácico, lumbar e inclinación pélvica de tenistas adolescentes en posiciones habituales (bipedestación y sedentación) y en posturas de máxima flexión y extensión del tronco, así como su extensibilidad isquiosural, antes y después de un entrenamiento. MUESTRA. Participaron en el estudio 40 tenistas varones entre 14 y 18 años (media de edad: 16,35 ± 1,82). Los criterios de inclusión de los tenistas fueron: seguir un entrenamiento sistematizado, al menos, durante cuatro años, no haber sido operado de la columna vertebral o de la musculatura isquiosural, ni tener algún tipo de lesión o alteración raquídea estructurada diagnosticada en el momento de la valoración que impidiera la realización de las mediciones. PROCEDIMIENTOS. Se valoró la disposición sagital del raquis y pelvis en las posiciones de bipedestación, bipedestación en autocorrección, máxima extensión en bipedestación, sedentación relajada, máxima flexión de tronco en sedentación, decúbito prono, así como la extensibilidad isquiosural mediante los test de distancia dedos-suelo, test de distancia dedos-planta y test de elevación de pierna recta activo y pasivo. Se realizó una primera medición antes de un entrenamiento estándar, y justo al finalizar el mismo. Para determinar la disposición angular del raquis y el ángulo de inclinación de la pelvis se utilizó un Spinal Mouse®. Para obtener dichos valores, una vez que el deportista adoptaba la posición a medir, se desplazaba el Spinal Mouse® por las apófisis espinosas desde T1 hasta S1. El entrenamiento específico de tenis que se realizó tuvo una duración total de 2 horas, con la siguiente estructura: 1) Calentamiento general, con una duración total de 10 minutos. 2) Calentamiento específico, con una duración de 10 minutos. 3) Trabajo específico de técnica en el que se realizaban correcciones de todos los gestos técnicos (30 minutos). 4) Trabajo de táctica: situaciones de juego reales controladas (30 minutos). 5) Situaciones reales de juego: se realizaron partidos y minicompeticiones entre los jugadores (40 minutos). CONCLUSIONES. 1) En la bipedestación, la gran mayoría de los tenistas presentan valores angulares normales tanto en la curva torácica como en la curva lumbar. En la sedentación relajada, casi la mitad de los tenistas presentan valores de normalidad tanto en la curva torácica como en la lumbar, siendo más frecuentes valores de hipercifosis torácica leve e inversiones moderadas en la zona lumbar. En la flexión máxima del tronco, los tenistas evidencian una gran movilidad de la zona lumbar en el plano sagital, mostrando una cifosis funcional tanto en la zona torácica como en la lumbar, ya que en bipedestación la mayoría de los tenistas presentan curvas normales. 2) Un entrenamiento tipo de tenis genera ligeros cambios en la disposición sagital del raquis y en la extensibilidad isquiosural. La fatiga podría ser la causa de la disminución de los casos de normalidad y el aumento de las hipercifosis en el raquis torácico y un aumento de casos de rectificación lumbar. Estos cambios no están asociados a cambios significativos en la inclinación pélvica. Las modificaciones en los valores angulares después del entrenamiento en la postura de autocorrección evidencian un menor control postural, el cual reduce la capacidad del tenista de modular su disposición sagital del raquis, probablemente debido a la fatiga muscular. El entrenamiento no parece tener una influencia significativa en la sedentación. Aunque, el entrenamiento provoca una limitación en la flexión pélvica asociada a un aumento de la cifosis torácica. En cuanto al efecto del entrenamiento en la extensibilidad de la musculatura isquiosural, se produce una mejora de la misma en todos los test utilizados para su valoración. 3) Dos tercios de los tenistas presentan valores considerados normales en la extensibilidad isquiosural. Al valorar la extensibilidad con test lineales, se observa un aumento de casos de cortedad isquiosural que evidencia una alteración del ritmo lumbo-pélvico. Por este motivo, test lineales no son adecuados para valorar la extensibilidad isquiosural en tenistas adolescentes.
INTRODUCTION A high volume of training in specific postures and repetitive movements could generate specific adaptations. For this reason, several studies have assessed the spinal curvatures in different sport disciplines, finding specific morphological spine adaptations depending on the sport practiced. However, the influence of tennis practice has not been sufficiently analyzed. Furthermore, few studies have examined the acute influence of training or competition. OBJECTIVE To determine the sagittal thoracic and lumbar curvatures as well as pelvic tilt of tennis players in several positions (standing, sitting and during trunk flexion and extension). Furthermore, the hamstring extensibility was evaluated with angular and linear tests. All measures were taken before and after a tennis training session. METHODS Forty adolescent tennis players from 14 to 18 years old (mean age: 16.35 ± 1.82 years) participated in this study. The inclusion criteria were: having played tennis for at least four years. The exclusion criteria were: a history of spinal and hamstring surgery, a medically diagnosed spinal disorder or having hamstring or spinal pain at the moment of the assessment. PROCEDURES Sagittal spinal curvatures and pelvic tilt were assessed in standing position, standing in self-correction, maximum trunk extension in standing, slumped sitting, maximum trunk flexion in seated position and prone lying. Hamstring extensibility was measured by the sit-and-reach test, toe-touch test and straight leg raise test (passive and active). The measurement was performed before (pre-test) and after a training session (post-test). Spinal Mouse® was used to determine the angular values of the spinal curvatures and pelvic inclination. The specific tennis session lasted for two hours and had the following structure: 1) General warm up, with a total duration of 10 minutes. 2) Specific warm up, lasting for 10 minutes. 3) Specific technical training in which technical corrections to all technical skills were made (30 minutes). 4) Tactical training in controlled real game situations (30 minutes). 5) Real game situations: matches and modified competitions (40 minutes). CONCLUSION 1) In standing position, most of the players have normal angular values in the thoracic and lumbar curvatures. In relaxed sitting, almost half of the tennis players have normal values in the thoracic and lumbar curves, being more frequent values of mild thoracic kyphosis and moderate lumbar kyphosis. In the position of maximum trunk flexion, the players show a great mobility of the lumbar spine in the sagittal plane, showing a functional kyphosis in both thoracic and lumbar spinal curvatures, as in standing position most of the tennis players presented normal curves. 2) Standard tennis training generates slight changes in the sagittal plane of the spine and hamstring extensibility. Fatigue could be the cause of the decline in cases of normal values and increased hyperkyphotic positions in the thoracic spine and more cases of lumbar hypolordosis. These changes are not associated with significant changes in the pelvic tilt. The changes in the angular values after training in self-corrected posture show less postural control, which reduces the ability of the tennis player to modulate their sagittal spinal curvatures, probably due to muscle fatigue. Training does not seem to have a significant influence the seated positions. However, training causes a limitation of the pelvic bending movement associated with increased thoracic kyphosis. As for the effect of training on the extensibility of the hamstring muscles, a improvement of it occurs in all tests used for its assessment. 3) Two thirds of the players have normal values on the hamstring muscle extensibility. In assessing the hamstring extensibility with lineal test, an increase in cases of hamstring shortness is observed,which shows an alteration in lumbopelvic rhythm. For this reason, lineal tests are not suitable to assess hamstring extensibility in adolescent tennis players.

O Homem em busca da sobrevivência interage com diversos elementos do ambiente, elementos estes inseridos num contexto genético, cultural e espiritual. Um desses elementos é a competição, estereotipada principalmente nas práticas esportivas, mas entendida de maneira Ecológica, passa a representar um elemento importante para a Mobilidade Sustentável na vida. Este estudo teve como objetivo principal, investigar a competição como elemento inerente da prática esportiva em adultos jovens do sexo masculino e feminino praticantes de tênis de campo da Universidade Federal de Santa Catarina (UFSC). A fundamentação teórica abordou temas norteadores, tais como a Teoria Ecológica sobre Competição (Donald Pierson, 1953); a Competição no Esporte e nas Relações Sociais; A Importância da Mobilidade Cotidiana na Sustentabilidade da Saúde e, a Teoria da Ação Racional - (Azjem & Fishbein, 1980). Esta investigação teve como população os praticantes de tênis de campo da Cidade Universitária em Florianópolis - SC e foi realizada em duas etapas; a primeira etapa, com característica descritivo-exploratória utilizando para coleta de dados o Questionário Internacional de Atividade Física Habitual (Soares, 2003); a segunda etapa, caracterizou-se como descritiva do tipo estudo de caso, utilizando-se como instrumento para coleta de dados uma entrevista semi-estruturada. Os resultados obtidos constataram uma população situada entre a faixa etária de 15 e 34 anos, solteiros, cursando nível superior e pertencentes a classe econômica "B" e "C". A maioria (82,1%) realizavam atividades físicas regulares e se consideravam mais ativos (56%) que outras pessoas da mesma idade. O principal fator evidenciado na dificuldade em realizar a prática de atividades físicas foi a falta de tempo (51,2%) e o que mais facilitou foi a vontade (45,2%) em realizar esta prática. Grande parte (70%) apresentou consumo acima de 3500 kcal/mets/semana e preferem como local para a prática de suas atividades físicas as ruas, os parques (53,9%), os clubes e as academias, respectivamente. A competição se constituiu no elemento essencial para a realização da prática esportiva em questão, possuindo estreita relação com os elementos norteadores da Mobilidade Sustentável.Ocorreu o aparecimento do elemento "vontade" vislumbrado como inerente aos praticantes de tênis aproximando-se do conceito de competição da Teoria Ecológica de Pierson (1953), fazendo emergir uma nova vertente da Mobilidade Sustentável a qual chamamos de Mobilidade Continuada voltada as características pessoais de cada indivíduo.

La siguiente investigación determina la factibilidad de una academia de tenis para menores de 4 a 14 años en la ciudad de Chiclayo. Para alcanzar dicho objetivo, el trabajo evalúa la demanda del servicio en la mencionada ciudad, o más específicamente dentro del Jockey club de Chiclayo. La investigación plantea un plan de marketing de acorde a las estrategias del proyecto, determina los requerimientos organizacionales y operativos para poner en marcha la empresa y analizar la rentabilidad del proyecto. Para lograr lo antes mencionado se planteó en la investigación un problema, del cual se derivó todo el proyecto y en base al cual se establecieron los objetivos. Posteriormente se diseñó la metodología del proyecto, donde se estableció como se alcanzaran dichos objetivos. Para ello antes de desarrollar los objetivos planteados sobre el plan de negocio en sí, se analizó el entorno en el cual se desarrollara; tales como la ciudad de Chiclayo, su gente, el sector recreación y deporte del Perú y de esta ciudad; para luego estudiar al público objetivo conociéndolo y entendiéndolo en base a observación e indagación.

A prática regular de atividade física está associada com redução no risco de desenvolver doenças crônicas, incluindo entre elas as doenças cardiovasculares (DCV). Entretanto, a inclusão de atividades esportivas no processo de prevenção e/ou de reabilitação de DCV ainda está pouco documentada. Desta forma, o objetivo principal deste trabalho foi avaliar os efeitos de um programa de tênis de campo adaptado para prevenção de DCV com duração de oito semanas, em indivíduos sedentários e com acúmulo de fatores de risco para desenvolver DCV. A amostra de estudo foi composta por quinze homens (idade média 44,9±4,9 anos) com moderado risco de desenvolverem DCV. As sessões de exercícios físicos seguiram uma metodologia adaptada de aulas de tênis de campo, praticada com intensidade constante e controlada entre 70% e 85% da frequência cardíaca máxima. No início e no final do programa foram avaliados o desempenho nos golpes específicos da modalidade, bem como variáveis fisiológicas, antropométricas, motoras, comportamentais, bioquímicas, e o risco de desenvolver DCV. Após aplicar o programa de exercícios foram observadas melhoras significativas no que se refere a: i) desempenho dos golpes específicos do tênis de campo (forehand, backhand, voleio de forehand e backhand, smash e saque), assim como para a regularidade em trocas de bola; ii) aumento no consumo máximo de oxigênio, velocidade pico, velocidades dos limiares ventilatórios 1 e 2, e no consumo de oxigênio do segundo limiar ventilatório; iii) redução da massa corporal, massa gorda, índice de massa corporal, percentual de gordura corporal, circunferência da cintura, e acúmulo de gordura abdominal; iv) melhoras nos parâmetros de flexibilidade, força, potência, velocidade e agilidade; v) qualidade de vida, hábitos alimentares e redução dos níveis de ansiedade; vi) redução das concentrações plasmáticas de colesterol total e colesterol-LDL, neopterina, e proteínas carboniladas; vii) aumentos nas concentrações de óxido nítrico plasmático e da atividade do complexo I da cadeia respiratória em isolado linfocitário, sendo que este parâmetro correlacionou positivamente com índices de aptidão cardiorrespiratória referentes ao primeiro limiar de transição fisiológica; viii) redução do escore de risco de Framingham. De acordo com estes resultados, podemos concluir que o programa adaptado de tênis de campo foi efetivo na melhora de parâmetros relacionados ao risco de morte por DCV

Abstract: The regular practice of physical activity has been associated to reduced risk of chronic disease development, including cardiovascular diseases (CVD). Although, little information is available in the literature on the practice of sports activities on primary and secondary prevention of CVD. In this scenario, the main objective of this study was to investigate, whether eight weeks of an adapted tennis lesson would induce health benefits in physically inactive subjects presenting, at least, two CVD risk factors. Participants were fifteen sedentary men (44.9 ± 4.9 years) with moderate risk for CVD development. Exercise training sessions were based on an adapted tennis lesson, which was taken under constant and controlled intensity between 70% and 85% of the maximum heart rate. The following parameters namely, tennis strokes efficacy, physiological, anthropometric, motor skills, behavior and biochemical variables, as well as, the Framingham risk score were assessed at baseline and at the end of the exercise program. After eight weeks of the program for health promotion, it was observed significant improvements as follows: i) tennis strokes efficacy (forehand, backhand, forehand and backhand volley, smash and serve), and the length of a rally; ii) maximum oxygen uptake, peak speed on the stress test, speed on ventilatory thresholds 1 and 2, oxygen consumption on second ventilatory threshold; iii) body mass, fat mass, body mass index, fat percentage, waist circumference and abdominal fat; iv) flexibility, muscular strength and power, speed and agility; v) quality of life, diet and anxiety levels; vi) plasmatic levels of total cholesterol, LDLcholesterol, neopterin and carbonylated proteins; vii) increased plasmatic nitric oxide, and lymphocyte respiratory chain complex I activity, which significantly correlated with the first ventilatory threshold; and viii) reduced Framingham risk score. These data show that the adapted tennis lesson improved parameters linked to CVD.
