| The purpose of this study was to investigate the effect of a period of corrective exercises on balance and performance of volleyball girls players with knee dynamic valgus defect. The statistical population of this study was all female volleyball players in East Azarbaijan who had knee dynamic valgus defect. Based on sample size formula, A sample of 30 subjects were selected from volleyball players with knee dynamic valgus defect. Subjects were randomly divided into experimental and control groups after completing the personal profile form and screening by squat test to diagnose knee dynamic valgus defects. Dynamic balance through Y balance test and upper extremity function by using Y test for upper limb were measured in both groups. Also explosive power was measured by the Sargent jump test in both groups. The experimental group then performed the corrective exercises for 10 sessions, three sessions a week, while the control group only did their specific exercises in volleyball. After the end of the training, subjects from both groups had a post test. The normality of the data was evaluated through Shapiro–Wilk test. To determine the effect of corrective exercise program on the dependent variables, the data were analyzed using covariance analysis and dependent T-test at the confidence level of (P ≤ 0.05). the Overall results indicated that corrective exercises had a positive effect on dynamic balance and upper limb function of volleyball players with knee dynamic Valgus defect. | ||
