Desequilíbrio muscular dos flexores e extensores do joelho associado ao surgimento de lesão musculoesquelética relacionada à corrida: um estudo de coorte prospectivo

Abstract

The aim of this study was to determine whether a muscle imbalance of the knee is associated with running injuries. Twenty runners were evaluated by an isokinetic dynamometer at 60, 180 and 300 degrees/second. Runners were followed for three months to determine the incidence of injuries. We used the chi-square test to verify the association between muscular imbalance and the appearance of injury. Four athletes experienced injuries (21%), all registered in the knee. Muscle imbalance was associated with running-related injuries for the three tested velocities (p < 0.05). To conclude, a muscle imbalance may be associated with running injuries.
