Comparison of Muscle Energy Technique vs Static Stretch in Vertical Jump of Basketball and Volleyball Player

In experimental group, post-isometric relaxation technique has given to the athletes. The position of athlete was prone and the involved group of muscle was quadriceps. Firstly end range of the quadriceps muscle group assess and guide the athlete to put 20% of their maximum voluntary contraction and physiotherapist resist the athlete and isometric contraction of quadriceps remain for 6-10 seconds
