To be successful in the game of tennis is dependent on the player’s technique as well as biomechanics which play a vital role in stroke production. A fundamental mechanical structure is founds in all tennis strokes.11 The backswing provides the distance. Tennis players need to be able to control the direction of the racket and the timing of the entire movement. The skill level of the tennis player depends largely on the mechanics of their forehand swing. The force of impact is determined by the racket speed at the moment it comes in contact with the ball. When maximum distance is used for accelerating that is when maximum velocity can be obtained. Body weight support is necessary for the forehand drive because shifting weight when striking the ball will increase ground reaction force to the body and the ball. A player wants to be balanced to direct power and energy without losing control. Forward momentum will carry the racket through the ball after contact. The follow through helps prepare the player for the next stroke. It should be long and the arm and racket should wrap around the body. It dissipates kinetic energy off the racket and that is when the player wants to arrive at the right point and balanced to be ready for the next stroke and to be able to play the ball back. The player’s body must absorb the remaining energy of the racket and the …show more content…
If the angle of rebound equals the angle of incidence, it will be realized that firmness of grip is an important factor in the direction taken by the struck ball.3 The firmness of the grip is a technical point for increasing the speed of the ball as it rebounds of the racket.4 When considering the inefficient motions and positions of various joints from a biomechanical aspect, the outcome can be detrimental to the speed and spin of the ball and may also be a cause of increased injury.12 Repetitive eccentric forearm muscle actions may be the primary cause of tennis elbow. Elbow kinetics of the forehand stroke has a pattern for player to produce a flexion torque throughout the swing. The rapid rotation of the trunk and upper arm makes the elbow joint extend causing the flexor muscles to contract as they try to control and maintain the position of the arm with the elbow slightly fixed. The torque is generated largest at the elbow. The upper arm is both horizontally adducted and externally rotated which causes the forearm and racket hand segments to lag behind. The combination of torques produces large forces on the medial side of the elbow and later side of the elbow joint. Tennis elbow is greater in players who play with a more bent elbow technique. Medial elbow tendinous is a condition that many tennis
