[4] Another seldom used shot is a behind-the-back shot, which, as its name suggests, is hit by crossing the preferred arm across his/her back without swinging. These swing patterns allow players to hit the ball from a more open stance, particularly when hitting forehands, but also when hitting two-handed backhands. The RMSSD values indicated a small intrasubject variability, and the recorded scapulothoracic joint angle patterns seemed reliable because the measurements errors were adequately smaller when compared to the scapulothoracic joint angle amplitudes observed in the present study. Example of humerothoracic and scapulothoracic joint angle patterns () as a function of time (s) for the three serves of one player, with. A passing shot is a groundstroke that is hit out of reach of an opponent at the net far to his left or right.

The scapula moves along the thoracic wall in coordination with the humeral motion to ensure the congruence of the humeral head into the glenoid cavity, with minimal stress on the glenohumeral passive structures (12). For more information, please refer to our Privacy Policy. Therefore, exercises preparing the body for these stresses are vitally important. It can be executed with either one or both hands. The tennis serve is a potentially injurious motion because of the repetitive nature of this overhead mechanics, the power, the acceleration required in a very short time, and the great loads applied onto the dominant upper limb, especially at the shoulder joint (9). may email you for journal alerts and information, but is committed The tennis serve was divided into four phases based on five key events. Both arms are used, increasing the power of the stroke, and fewer body segments are involved, which helps learning players co-ordinate the movement.
