Brief summary
It has been shown that 90% of swimmers experience shoulder pain at some point in their career. During the macrocycle, swimmers present significant alterations in the muscular balance between external and internal rotators of the shoulder: the IR assumes much prominence in strength levels and RE goes progressively weaker. furthermore, all overhead athletes (such as swimmers) present a glenohumeral Internal Rotation Deficit and an increase in External Rotation. The objective of this study is to propose an exercise with an elastic band aimed to strengthening the RE of the shoulder to analyze the effects on the muscular balance between IR and RE. In addition, the effect caused in the limitation of internal rotation is going to be studied
