Short-term effects of combined training on the performance of the Brazilian women's basketball team / Efeitos de curto prazo do treinamento combinado da seleção brasileira de basquetebol feminino

Abstract Competitions are considered of paramount importance for high-performancesports because they determine the entire orientation of the training process. When analyzing the calendar of the International Basketball Federation, it can be observed that international competitions occur in short periods of time. In this sense, the aim of this study was to verify the effects of the application of combined training in the short-term preparation period on the speed of athletes of the Brazilian women's basketball team. Thirteen athletes participated in this study, who took part of the preparation for the 2015 Pan American Games. Athletes were submitted to anthropometric measures and biomotor capacity evaluation at cyclic speed -20m run, and acyclic speed - T test at the beginning (M0) and end of a 27 - day preparation period (M1). Considering the period available for training, the total duration percentage was:technical / tactical 73.7%, strength and conditioning: 5.7%, preventive: 10.5% and general and special warm up: 10.1%. After data collection, the Shapiro-Wilk test was used to verify normality and then, the Student's T test was also applied. The main results indicate that the best time to evaluate cyclic speed (M0 and M1, respectively) was 3.34 ± 0.22s and 3.39 ± 0.21s and acyclic speed (M0 and M1, respectively), 9.30 ± 0.49s and 9.52 ± 0.57s.The results of the current study suggest that short-term intervention was not efficient to improve the cyclic and acyclic speed of female basketball athletes.

Resumo As competições são consideradas o elemento central para o desporto de rendimento, pois determinam toda a orientação do processo de treinamento. Ao observar o calendário da Federação Internacional de Basquetebol, percebe-se que as competições internacionais acontecem em curtos períodosde tempo. Neste sentido, o objetivo deste trabalho foi verificar os efeitos da aplicação do treinamento combinado na preparação de curto prazo, sobre a capacidade biomotora velocidade, em atletas adultas da seleção brasileira de basquetebol feminino. Participaram deste estudo 13 atletas da seleção brasileirade basquetebol feminino da categoria adulta, que fizeram parte da preparação para a disputa dos Jogos Pan Americanos em 2015. As atletas foram submetidas a medidas antropométricas e avaliação da capacidade biomotora velocidade cíclica - corrida de 20m, e acíclica - teste T, no início (M0) e ao final de um período de preparação de 27 dias (M1). Considerando o período disponível para treinamento o % da duração total foi de: técnico/tático 73,7%, físico: 5,7%, preventivo: 10,5% e aquecimento geral e especial: 10,1%. Após a coleta dos dados utilizou-se o teste de Shapiro-Wilk para verificar a normalidade e, a seguir, o teste T de Student. Os principais resultados apontam que o melhor tempo para avaliar a velocidade cíclica (M0 e M1, respectivamente), foi de 3,34±0,22s e 3,39±0,21s e, na acíclica (M0 e M1, respectivamente), foi de 9,30±0,49s e 9,52±0,57s. Conclui-se que durante um curto período de intervenção, com grande concentração de estímulos, não foi eficiente para melhorar a capacidade biomotora velocidade cíclica e acíclica.

Shoulder isokinetic profile of male handball players of the Brazilian National Team

BACKGROUND: Data obtained on an isokinetic dynamometer are useful to characterize muscle status and have been reported in muscle imbalance studies in different types of sport. However, few studies have assessed elite handball players to establish reference values. OBJECTIVE: The purpose of this study was to compare, for the dominant (D) and non-dominant (ND) side, the isokinetic profile of shoulder rotator muscle strength between male handball players (H) and asymptomatic non-athletes (NA). METHOD: Isokinetic concentric and eccentric strength tests for D upper limbs were performed by the H group (n=20) and the NA group (n=12). Internal and external rotator muscle peak torque in concentric action was assessed at 60°/s and 300°/s and in eccentric action at 300°/s. We also calculated conventional balance (the ratio of external rotator peak torque to internal rotator peak torque in concentric action) and functional balance (the ratio of external rotator peak torque in eccentric action to internal rotator peak torque in concentric action). RESULTS: In the H group, dominant limbs were stronger in concentric action for external rotation at 60 and 300°/s. The conventional balance ratio for the D side was significantly lower at 60 and 300°/s for H compared to NA. The functional ratio for the D side was significantly lower at 300º/s for H compared to NA. CONCLUSIONS: Compared to asymptomatic non-athletes, handball players presented significant muscular imbalance resulting from daily sports practice, a known risk factor for shoulder injuries. .
