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.
