Comparison of hip muscle strength profiles with healthy sedanter in adolescent tennis players according to tennis playing year

In the studies with tennis players, upper extremity injuries and shoulder muscle strength were examined, while normal range of motion of the lower extremity and muscle strength around the knee were examined. No studies have examined the muscle strength and femoral anteversion angle of the hip in these individuals. Therefore, the aim of this study is to evaluate the muscle strength and muscle strength ratios of the tennis players according to the year of playing tennis and to compare them with healthy controls. It is planned to take 40 athletes who play active tennis for at least three years and 20 healthy sedentary in the age range of 10-18. Isometric muscle strength of external rotation in abduction which is used to determine hip stabilization by hip abductor-adductor extensor-flexor, external and internal rotator isometric muscle strength test will be evaluated for the athletes included in the study. In addition, the femoral anteversion angle will be measured. The data obtained will be compared between groups.
