This movement was applied as a means of improving Samuel's shoulder relaxation and shoulder/scapular stability...Relaxation refers to the ability to stay calm during repeated motion or high-intensity movements. Tension in the wrong areas of the body can impede the elastic response of the muscle, ultimately reducing the level of power that can be developed...Shoulder/scapular stability refers to the ability of the shoulder complex to maintain the position of the upper extremity and safely conduct the demanding overhead movements of an attacking volleyball player.
