Resumo: | The aim of this study was to analyze the effect of Basketball match work simulation on peak torque (PT) of ankle evertor and invertor muscles and on eccentric evertor/concentric invertor torque ratio (EVEECC/INVCON). Ten healthy college basketball players, without mechanics or functional ankle instability performed a laboratory-based protocol representative of work rates observed during basketball match-play. The test was composed of a succession of intermittent physical effort equally distributed in four periods of 10 minutes each, considering the mechanical and physiological demands of a basketball match-play. Prior to the start of the trial (Evaluation 1) and after 2° (Evaluation 2) and 4° (Evaluation 3) period, the subjects performed five maximal isokinetic concentric and eccentric contractions of ankle invertors and evertors muscles, separated by two minutes rest, at 60 °/s and 120 °/s. After testing for normality of data distribution with the Shapiro-Wilk test, was used the ANOVA repeated measures and post-hoc Bonferroni test for comparison of variables between assessments. Was adopted p < 0.05. There was no significant difference for EVEECC/INVCON torque ratio between assessments. However, there was a decrease in PT EVEECC at 60º/s and 120º/s for the Evaluation 2 when compared to Evaluation 1. There was a reduction of PT INVCON values in relation to Evaluation 1, compared to Evaluation 2 at 60°/s and to Evaluation 3 at 120°/s. Given these results, we conclude that the progress of simulation basketball match-play lead a reduction on PT of the ankle evertors and invertors muscles. Key words: Sprains and Strains; Muscle Strength; Joint Instability; Isokinetic Dynamometer. |

Dez basquetebolistas universitários saudáveis, sem instabilidades mecânicas ou funcionais no tornozelo realizaram uma simulação do jogo de basquetebol a partir de um teste laboratorial. O teste foi composto por uma sucessão de esforços físicos intensos e breves distribuídos igualmente em quatro períodos de 10 minutos cada, considerando demandas mecânicas e fisiológicas de um jogo de basquetebol. Previamente ao início do teste (Avaliação 1) e após o 2º (Avaliação 2) e o 4º (Avaliação 3) período, foram realizadas cinco contrações isocinéticas máximas concêntricas e excêntricas dos grupos musculares eversores e inversores do tornozelo, separados por dois minutos de intervalo, nas velocidades de 60º/s e 120°/s. Após a verificação da normalidade de distribuição dos dados com o teste Shapiro-Wilk, utilizou-se o teste ANOVA medidas repetidas e o teste post-hoc de Bonferroni para a comparação das variáveis entre as avaliações. Adotou-se p < 0.05. Não houve diferença significativa para a razão EVEEXC/INVCON entre as avaliações realizadas. Entretanto, verificou-se declínio do PT EVEEXC a 60º/s e 120º/s para a Avaliação 2 quando comparada à Avaliação 1. Para o PT INVCON observou-se redução dos valores em relação à Avaliação 1, quando comparados à Avaliação 2 a 60º/s e à Avaliação 3 a 120º/s. Diante destes resultados, conclui-se que o progresso da simulação do jogo de basquetebol promove redução do PT dos músculos eversores e inversores do tornozelo.
