Este estudo teve como objetivo analisar a força isocinética do joelho da perna preferida (PLs) e da perna não preferida (NPLs), as razões de assimetria lateral e examinar a sua correlação com o equilíbrio estático. Dezesseis mulheres atletas de taekwondo (TKD) participaram voluntariamente no estudo. A força de extensão (Ex) e flexão (Flx) isocinética do joelho foram medidas em contrações concêntricas / concêntricas (Con/Con) em velocidades angulares de 60°/s, 180°/s e 240°/s. Foram calculadas as rácios isquiotibiais / quadríceps ipsilaterais (H/Q) e bilaterais (H/H e Q/Q). Os equilíbrios estáticos foram determinados tomando o centro de pressão corporal nos eixos X (COPX) e Y (COPY). O teste t de amostra emparelhada e os testes de correlação de Pearson foram usados na análise estatística. Quando a força isocinética do joelho foi examinada, verificou-se que o parâmetro de velocidade angular de 60°/s foi significativamente diferente na fase Flx, enquanto as velocidades angulares de 180°/s e 240°/s foram significativamente diferentes na fase Ex em favor de PLs. Não houve significância nas rácios de força bilateral e ipsilateral de todas as velocidades angulares. Houve uma correlação significativa entre HQ de 240°/s e COPX, em termos de rácios de assimetria ipsilateral, enquanto uma correlação significativa foi encontrada entre HH de 60°/s e COPX em termos de rácios de assimetria bilateral. Verificou-se que havia diferenças de força entre PL e NPLs, mas nenhuma assimetria foi observada. Não houve um alto nível de correlação entre as rácios de assimetria lateral e equilíbrio em mulheres praticantes de TKD.
