O tênis de campo como conteúdo de ensino: a percepção de professores de Educação Física / Field tennis as a teaching content: the perception of Physical Education teachers / El tenis de campo como contenido didáctico: la percepción de los profesores de Educación Física

RESUMO Investigou-se a percepção de professores de Educação Física da Rede Municipal de Ensino de Florianópolis (RMEF) acerca da inserção do tênis de campo como conteúdo de ensino. Por meio de uma abordagem quanti-qualitativa e descritiva, elaborou-se o Instrumento de Percepção do Ensino do Tênis de Campo (IPET), respondido por 23 professores. Os resultados revelaram que as estratégias e as possibilidades de inserção do conteúdo sobre o tênis de campo referem-se à formação inicial, às experiências e aos conhecimentos específicos dos professores. Verificou-se um baixo quantitativo de docentes que ensinam a modalidade, relacionado ao pouco conhecimento e aos recursos materiais disponíveis.

ABSTRACT The perception of Physical Education teachers from the Rede Municipal de Ensino de Florianópolis/Brazil (Municipal Education Network of Florianópolis) about the inclusion of field tennis as a teaching content was investigated. Through a quantitative-qualitative and descriptive approach, the Field Tennis Teaching Perception Instrument (Instrumento de Percepção do Ensino do Tênis de Campo - IPET) was elaborated, validated and answered by 23 teachers. The results revealed that the strategies and possibilities for inserting content about field tennis refer to initial training, experiences and specific knowledge of teachers. There was a low number of professors who teach the modality, related to the little knowledge and material resources available.

Efeitos agudos da ingestão de cafeína no desempenho em teste específico de pádel / Acute effects of caffeine consumption on performance in specific test paddle / Efectos agudos del consumo de cafeína en el rendimiento de una prueba específica de pádel

Resumo Objetivou-se mensurar os efeitos da cafeína em teste de precisão de voleio específico (TPVE). Após 30 min da ingesta de 6mg•kg-1 de cafeína (CAF) ou placebo (PLA), 12 atletas fizeram duas sessões de treino de 45 min. Mediu-se resistência de preensão manual (RPM), foram registradas frequência cardíaca (FC) e percepção subjetiva de esforço (PSE) e foi conduzido TPVE. Não foram observadas diferenças na FC máxima, PSE e RPM entre condições. No TPVE, feito após a sessão de treino, registraram-se 31 ± 3,2 e 34,4 ± 4,6 pontos para PLA e CAF, respectivamente (p < 0,05; d = 1,06). Indica-se 94% de provável efeito positivo com a ingestão de CAF e se conclui que CAF pode aumentar a eficiência em gestos específicos após treino de pádel.

Abstract The study aimed to investigate the effects of caffeine on performance of specific precision paddle test. Twelve paddle athletes performed two specific training sessions of 45 minutes, preceded by 6mg•kg-1 of caffeine (CAF) or placebo (PLA) 30 min before. Pre and post-workout was measured handgrip endurance, recorded heart rate (HR) and rating of perceived exertion (RPE) and conducted specific volleying test. The % of maximal HR in CAF and PLA post-training were 93.6±3.3 and 92.1±4.4 respectively. There were similar responses of RPE and handgrip endurance. In the specific test was reached 31±3.2 and 34.4±4.6 points in PLA and CAF, respectively, was evidenced a 94% probable positive effect of CAF. Therefore, the CAF seems to increase efficiency in specific actions after an intense paddle workout.

Resumen El objetivo del estudio fue medir los efectos de la cafeína en el rendimiento de una prueba de precisión específica de pádel. Doce jugadores de pádel llevaron a cabo dos sesiones de entrenamiento específicas de 45 minutos, precedidas por la ingesta de 6mg•kg-1 de cafeína (CAF) o placebo (PLA) 30 minutos antes. Se midió la fuerza de prensión manual previa y posterior al entrenamiento, la frecuencia cardíaca (FC) registrada y el esfuerzo percibido (EP), y también se realizó una prueba específica de pádel. El porcentaje de FC máxima en CAF y PLA después del entrenamiento fue 93,6±3,3 y 92,1±4,4, respectivamente. Fueron similares el EP y la prensión manual. En la prueba específica se registraron 31±3,2 y 34,4±4,6 puntos en PLA y CAF, respectivamente, y el 94% del efecto positivo sobre la probable ingesta de CAF. Por tanto, la CAF parece aumentar la eficiencia en gestos concretos después de una intensa sesión de ejercicios de pádel.

Família dos jogos esportivos com raquetes: metodologia e procedimentos pedagógicos / Family of racket sports games: methodology and procedures educational

Objetivou apresentar os procedimentos pedagógicos para o ensino dos esportes com raquetes pautando-se na família de jogos esportivos. Os resultados indicam que embora os jogos esportivos com raquetes apresentem características específicas e auto afirmativas que os constituem como únicos, elementos estruturais (regras, implemento, jogadores e alvo), elementos funcionais operacionais de ataque (lançar a bola/implemento para o espaço adversário com o objetivo de marcar pontos) e de defesa (controlar a bola devolvendo para o espaço adversário) e regras de ação de ataque (tentar marcar o ponto, tentar lançar a bola com maior nível de dificuldade e controlar a bola para devolver ao campo adversário) e defesa (antecipar a trajetória do ataque, persuadir o erro do adversário, impedir o ponto) são similares em todos, os integrando a família de jogos esportivos com raquetes. Foi possível explorar diferentes manifestações de jogos esportivos com raquetes, ampliando as possibilidades desta manifestação esportiva....(AU)

The theoretical and practical, the study aims to present pedagogical methods for teaching racquet sports basing on family sports games. Although sports games with rackets show their special features and self statements that constitute the structural elements (rules, implement, players and target), operating functional attack elements (e.g. throw the ball/attachment to the opponents' space in order to score points) and defense (e.g control the ball returning to the opponent's space) and attack action rules (e.g mark the spot, trying to throw the ball with the highest level of difficulty and control the ball to return the opponent's field) and defense (e.g..anticipate the trajectory of attack, persuade the pponent's error, stop point) are similar in all, integrating into a family of sports games with rackets. It was possible to explore different manifestations of sport games with rackets, expanding the possibilities to live with this sporting event....(AU)

Morfología del jugador de élite de pádel - comparación con otros deportes de raqueta / Morphology of the elite paddle player - comparison with other racket sports

El rendimiento deportivo se encuentra asociado a una óptima morfología del deportista. El pádel que es un deporte que posee gran número de adeptos, necesita de mayor información acerca de los jugadores que lo practican. El objetivo del presente estudio fue describir el somatotipo antropométrico de 48 jugadores de alto rendimiento en pádel. Un análisis de la varianza fue aplicado para hallar diferencias entre categorías de juego y la pruena T-Student para aquellas en función del sexo y el rendimiento deportivo (ganadores y perdedores). Las variables de peso, talla e Índice de Masa Corporal son similares entre las diferentes categorías de jugadores analizados, excepto entre hombres y mujeres. El somatotipo dominante de los jugadores fue meso-endomórfico (3,6 - 6,9 - 1,9 y 4,1 - 5,4 - 3,0; en hombres y mujeres, respectivamente). Las distancias de dispersión del somatotipo muestran diferencias significativas con otros deportes como el squash, bádminton y tenis. Los resultados aportan información relevante para determinar la morfología ideal de los jugadores de pádel, hasta la fecha desconocido.

Athletic performance is associated to an optimal morphology of the athlete. Paddle-tennis is a sport with a large number of followers needing more information about the players who practice it. The aim of this study was to describe the anthropometric somatotype of 48 high-level paddle-tennis players. ANOVA was applied to find differences between categories of the game and a T-Student test for those based on sex and athletic performance (winners and losers). The variables of weight, height and BMI are similar between players of different categories, except between males and females. Dominant somatotype of players was Meso-Endomorphic (3.6 - 6.9 - 1.9 and 4.1 - 5.4 - 3.0; in males and females, respectively). The somatotype dispersion distances show significant differences with other sports such as squash, badminton and tennis. The results provide important information to determine the ideal morphology of paddle-tennis players, so far unknown.

The Analysis of Physical Fitness and Performance Level Depending on Play Style in Female Table Tennis Players / 대한스포츠의학회지

The purpose of this study was to analyze the physical fitness and performance level depending on play style in female table tennis players. Thirty-one female players participated in this study. The measurement factors for physical fitness were body composition, cardiopulmonary function and fitness, balance, power, flexibility, agility, isotonic and isokinetic strength, muscle endurance and anaerobic. Kruskal-Wallis test, Mann-Whitney test, and Spearman correlation were used to analyze the data. The results were as follows; in cardiopulmonary function and fitness, FEV1/FVC was significantly higher in defensive style than drive style. Also, Harvard step test was significantly higher in drive style than attack style. In agility, cross run was significantly slower in attack style than the other styles. In isokinetic strength, left flexion strength of knee was significantly higher in driver style than defensive style. Also, in correlations, performance level had association with Harvard step test in defensive and attack style, 20 m run in attack style, cross run in defensive and drive style, push-ups in drive style. As different physical fitness factors were correlated on performance and scientific training program should be applied according to the play styles.
