Introduction
Plyometric training is generally expected to enhance performances during stretch–shortening cycle (SSC) exercises. Among the mechanisms of plyometric training, it is possible to mention the potential of the electric currents of the muscle (neural adaptations), biochemical-mechanical potential, and restoring the elastic energy of the musclesThe most important factor in controlling movement in the knee is the responsibility of the quadriceps and hamstring muscles, and due to the importance of the flexion mechanism, the function of the quadriceps muscles is very important in the movement control process with concentric and eccentric contractionsThe increased homogeneity in muscle activity at the moment of landing begins before the foot contact and provides greater protection and stability of the joint against damage
