Brief Summary

Introduction. Shoulder injury is the pathology that causes the longest downtime in rugby players, representing 66% of upper limb injuries in this discipline. The lack of strength, and instability are factors that predispose the athlete to suffer this type of dysfunction. The intervention of the study consists of a training program that counteract these dysfunctions. Aim. Assess the effectiveness of a program using plyometric, proprioceptive and strength exercises on 18-45-year-old rugby players to improve strength and stability. Study design. Clinical randomized, prospective, single-blind and trackable. Methods. The subjects included in two study groups, experimental and control, will be attributed a random order. The treatment will last 4 weeks, with 2 weekly sessions, of approximately 25 minutes each. The study variables will be strength, stability and functionality. A descriptive statistical analysis will be carried out calculating the main statistical characteristics. Through of a Kolmogorov analysis the normality of the sample will be assessed. A t-Student test for paired samples will be performed for the difference between the means of the dependent and independent variables. An analysis if variance (ANOVA) for repeated measures will be used to compare the means and checked to what extent the intra-subjects factors influence the dependent variables. Expected results. Improved shoulder strength, stability and functionality for the subjects on which the study is carried out.

Outcome Measures

Primary Outcomes (1)

• Change from baseline strength after treatment and at 1 month

  The strength assessment will be carried out with a dynamometer. The subject will stand up and the examiner will indicate when the movement should begin. The dynamometer will be positioned to measure the strength of the shoulder abductors and rotators in the position of 90º of abduction and 90º of external rotation. The unit of measure is the Newton

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Secondary Outcomes (2)

• Change from baseline stability after treatment and at 1 month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

• Change from baseline functionality after treatment and at 1 month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Study Arms (2)

Experimental group

EXPERIMENTAL

Exercise 1 with medicine ball. Standing player with 90º shoulder abduction and elbow flexion. He will receive the ball with an external rotation returning it with internal rotation. Exercise 2 with elastic band. From standing, he will fix the elastic band with his foot and perform a shoulder flexion with his contralateral limb. Exercise 3 of iron with support of the hands on the floor and shoulder, elbow and wrist aligned. You should perform a scapula approach and separation without altering its initial position. Exercise 4 BodyBlade ©. From standing with 90º of 90 ° shoulder abduction and elbow flexion. It will perform an anteroposterior thrust, causing a wave effect to stabilize the shoulder joint for 30 seconds. Athletes will do 15 repetitions of each exercise.
