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.
Interventions
OTHERexercises
Those subjects included in the experimental group will receive an intervention through a program with plyometric, proprioceptive and strength exercises. The subjects included in the control group will not receive any intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline strength after treatment and at 1 month | Screening visit, within the first seven days after treatment and after one month follow-up visit | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 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 | It will be assessed with the Closed Kinetic Chain Upper Extremity Stability Test. The initial position of the test is a push-up position with the upper extremities perpendicular to the ground. We will use two strips of 3.80 cm tape stuck on the floor and separated 91.44cm apart. The subjects will carry one of the hands until they touch the other strip of tape and return to the initial position. The touches will be counted every time one of the tape strips is touched in a total time of 15 seconds. Each subject will perform a warm-up, followed by 3 attempts with a break between attempts, of 45 seconds, averaging the 3 data obtained. |
| 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 | The assessment will be carried out with the Simple Shoulder Test. This test is a questionnaire of 12 questions, with two answer options: yes (when the subject is able to perform the task) and no (when he is not able to do it). The results obtained have a scoring range from 0 to 12, with 0 being the lowest functionality and 12 being the highest. |
