Creating the mental projections of future movement, before the physical response is initiated, is always dependable on the dynamic changes of the environment to which we have to be attentive constantly in order to adapt efficiently

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
In tennis, the player transfers the energy from the body to the ball through a tennis racket to generate speed and spin of the ball. The loaded energy is the potential (stored energy) is transferred through the kinetic chain into the moving energy (the energy of movement) of the body segments in the timely manner through the ball into the wanted direction
In the game of tennis the beginning of the stroke and the end of it are not that obvious, as many players are thinking only on about taking the racquet back and hitting the ball
The hip musculature generates the majority of power for the successful stroke. In simple words, if the player uses the wrong sources of power, most likely that she/he will lose the stability and balance during the acceleration phase. As mentioned in previous blogs, the source of the power comes from the ground, and its forces. These forces are transferred from the ground to the hip muscles and core, and at this point is where rotational and linear forces work together. The transfer of energy in linear and rotational mode wouldn’t be possible without a“stiffened” core and serape musculature
