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

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
