Abstract
Post activation potential is a relatively well-known topic in the field of strengthening and fitness training across many sports activities, where an immediate increase in maximum performance for a specific muscle group is expected based on the previous load. In our project, we assume the mentioned positive effect also in exercises focused on the development of strength skills in the area of the shoulder joint, in exercises supporting its stability.
The use of exercises is diverse in terms of the nature of external resistance, such as the weight of the body or its parts or various forms of external resistance. In the case of dynamic stabilizers, the stability of the shoulder joint is ensured primarily by the muscles of the rotator cuff during all movements and positions that are implemented in the shoulder girdle.
The condition of the rotator cuff muscles and their mutual cohesiveness is essential for the stability of the glenohumeral connection of the shoulder girdle. In the event of asymmetry or disturbance of the interaction of the individual muscles of the rotator cuff during the movement, destabilization may occur, and thus a glocation of the glenohumeral connection.
The aim of the project is to evaluate the effect of post-activation potential on the stability of the glenohumeral connection.
