Brief Summary

Introduction. Myofascial therapy aims to improve fascial restrictions through the application of mechanical stimuli. The eccentric exercises involve the recruitment of fast fibers and help increase muscle volume.

Aim. Compare the effectiveness of myofascial induction intervention in the improvement of the range of motion of glenohumeral rotation and the pain perception, with respect to the use of eccentric exercises in volleyball players from 18 to 35 years of age.

Study design. Multicenter and single-blind randomized clinical study with follow-up period.

Methods. A random assignment of the 40 subjects recruited to the different study groups will be carried out: experimental (myofascial induction technique and eccentric exercises) and control (eccentric exercises). The intervention will last 4 weeks, with a weekly session of 17 and 7 minutes (in the experimental and control group, respectively). The dependent variables and measurement instruments will be: internal and external shoulder rotation (goniometry) and pain perception (visual analog scale). The Kolmogorov-Smirnov test will calculate the distribution of the sample, using parametric tests (t-student to calculate the difference of means between the evaluations in each group and ANOVA of repeated measures to calculate the intra- and intersubject effect) in case of normal.

Expected results. To improve the range of motion of glenohumeral joint global rotation and of the perception of pain of the subject.

• Intervention Model: PARALLEL
• Primary Study Purpose: PREVENTION
• Blinding Strategy: SINGLE

Study Groups

Myofascial

Each session will last 17 minutes, taking place for 1 day a week, in a period of 4 weeks. The intervention will be carried out at the end of the training session. After the training, the technique of myofascial induction and eccentric exercises will be performed.

Group Type: EXPERIMENTAL

Experimental

Intervention Type: OTHER

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

Eccentric

Each session will have a duration of 9 minutes, taking place during 1 day a week, in a period of 4 weeks. The intervention will be carried out at the end of the training session. After the training, the eccentric exercises will be performed.

Group Type: ACTIVE_COMPARATOR

Control

Intervention Type: OTHER

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.
