Resumo

Nesse estudo, comparamos os parâmetros de força do joelho testados em jogadores profissionais de futebol nas temporadas preparatória e competitiva, separados por 12 semanas. Pico de torque dos extensores e flexores do joelho, razão convencional isquiotibiais/quadríceps (I/Qcon) e índice de assimetria bilateral (IA) nos membros dominante e não dominante de 10 jogadores de futebol foram avaliados em um dinamômetro isocinético. O teste t pareado foi usado para comparar todas as variáveis ​​entre as temporadas preparatória e competitiva. Um teste t de uma amostra foi usado para comparar a I/Qcon e o IA com médias teóricas definidas como 0,6 e 10%, respectivamente. Os resultados mostraram melhora significativa do pico de torque no lado dominante tanto para extensores de joelho (p=0,013) quanto para flexores (p=0,003), enquanto no membro não dominante não houve diferença significativa. Em relação à I/Qcon, os lados dominante e não dominante ficaram abaixo de 0,6 durante as temporadas preparatória e competitiva (p<0,001). O IA foi significativamente menor que 10% para os extensores do joelho durante a temporada competitiva (p=0,001) e para os flexores do joelho durante a temporada preparatória (p=0,005), sem diferença entre as temporadas preparatória e competitiva para os extensores e flexores do joelho. Esses resultados indicam que a prática profissional de futebol aumenta potencialmente as assimetrias de força entre os membros inferiores, portanto, a dominância dos membros inferiores deve ser considerada na elaboração de programas de treinamento de resistência e prevenção de lesões para jogadores profissionais de futebol, bem como atenção especial deve ser dada ao fortalecimento dos músculos flexores do joelho.
