Myofascial Induction and Eccentric Exercises in Volleyball Players

The intervention by myofascial induction will consist of the application of two techniques: global technique of myofascial induction of the pectoralis major muscle (once the tissue is placed in tension, the direction of fascia release in that region should be followed and as a result of the release, the caudal hand can move to the pelvis in any direction, to the right or to the left) and telescopic technique for the upper extremity of the subject's dominant arm (gently tractioning the upper limb of the subject, making a slight external rotation, so slow and progressive). The subjects will then perform the eccentric exercises, which will also be done by control group subjects

The intervention by eccentric exercises will consist of two exercises using an elastic band. In the supine position, with the elastic band on the contralateral side attached to a fixed body perpendicular to the subject's hand performing a slow and constant movement of external rotation against resistance in an approximately 45 degree arc; holding for 5 seconds and relaxing slowly (perform 3 sets of 12 repetitions). The second exercise, with the elbow in 90 degrees of flexion and a shoulder abduction also of 90 degrees, with the elastic band in front of the subject, executing a movement against resistance performing an external rotation.
