To validate both the Athletic Shoulder (ASH) test, conducted on rugby players, and its inverse, the Inverse Athletic Shoulder (IASH) test, for swimmers. This involves assessing the strength relationship between shoulder flexion and extension at three different adduction angles (180º, 135º, 90º) to identify potential injuries associated with these imbalances.
