ABSTRACT

The purpose of this study was to diagnose balance ratio of the dominant (extensor) and antagonist (flexor) muscles, and balance the ratio between the left and right sides in collegiate women's hockey players, and to provide strength training prescriptions for individual athletes who were evaluated as having an imbalance. The subjects of this study were six female hockey players from K-University who had an imbalance in knee strength assessment in Seoul. After measuring their body composition, isokinetic muscle function of the knee joint was measured at an angular velocity of 180°/sec. The results for each athlete were as follows. First, the balance of the ipsilateral flexion-extension ratio (H/Q) was evaluated in lower; in the right leg of athlete A, in the left leg of athlete B, in the left leg of athlete C, in the left leg of athlete D, in the left leg of athlete E, and as normal leg of athlete F, respectively. Second, the balance of bilateral left-right strength ratio (L/R) was evaluated in lower; in flexor of Player A, as normal of Player B, in flexor of Player C, in flexor of Player E, and as normal of Player D and Player F, respectively. Considering the above overall individual cases, as previously mentioned in this study, regular isokinetic muscle function tests should be performed to evaluate whether there is an imbalance of ipsilateral and bilateral balance ratio or not, and then appropriate strength training, especially hamstring muscle strengthening training, is thoroughly required for each individual cases.
