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
Creating a feeling of proper loading and unloading the body parts is first step in creating the awareness of the power source
After the contact phase, it is all about directing the ball and deceleration of the whole movement in the way that the muscles, tendons and ligaments are protected from the chronic injuries.
It’s amazing that we can have the real time feedback about the ratio of the proper to unproper muscles used during the stroke execution using Athos equipment.
Contact point is the peak of the acceleration phase. The energy created through the kinetic chain is finally transferred into the distal wrist joint directing the energy of the leg drive, trunk rotation, shoulder internal rotation, forearm pronation and finally the wrist flexion into one special point of time and space
In the cocking phase, the elastic energy is stored in the major slow moving muscle groups, and through the acceleration phase, this energy is released through the faster moving muscle groups to the ball. How?
