TENNIS GAME – THE GAME OF MOMENTUMS

Momentum measures the ‘motion content’ of an object and is based on the product of an object’s mass and velocity. For players to perform accurate strokes with high velocity, there should be an optimal combination of linear and angular momentum. The optimal combination depends on the urgency of movement, level of balance, perception of the situation and even level of confidence. With a creation of a larger momentum, greater forces and abilities are required from a hitter to decelerate to set up and execute a successful stroke

Attention in tennis. Transition from an external to the internal focus

Tennis game relates to the changes from external to internal focus. Incoming ball with all the changes in intensity and pace should be recognized as soon as possible so the prediction of the ball bounce would quicken the preparation for the technical-tactical execution. 

Players focus externally to determine the properties of the incoming ball and make a decision of the preparation and timing of their set-up for the stroke. As the ball is external object to which trajectory and intensity a player responds, players are in need of the recognizing the external stimulus – ball. As soon as the spatio-temporal characteristics (intensity, pace and court area where the ball will bounce) of the incoming balls are recognized, player can transition the attention to creating internal (own) responses. Internal responses are determined by the decision of the movement response and the technical-tactical execution

PRINCIPLES OF THE EFFICIENT MOVEMENT and PERFORMANCE

For a player to move the body segments efficiently, there should be optimal combination of the stability and mobility through lowering the center of gravity created by loading the major muscle groups of the lower extremities.

Upper body force creation depends of the elastic capabilities of the muscles of the trunk. The reason the players create a larger upper trunk rotation beyond the hips is to pre stretch the trunk rotator muscles and create a powerful separation angle
