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

Unit turn, loading, unloading, stretch shortening momentum and finishing of the stroke
The center of the mass of the body is directly connected with the centering of the athlete’s mind. As centering of the mind makes the athlete more grounded, calm and relaxed, it lowers the levels of anxiety. Centering the thoughts, the athlete can be fully aware of the body’s position and to be exact – it’s center of mass and transfer of weight around it
