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

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

Body segments must be coordinated and synchronized in such a way that a highest racquet speed is generated at the impact point.

Linear momentum in the serve motion is achieved when the whole body has reached the height from where the player can produce the perfect upper body turn (angular momentum) and create the most efficient follow through movement. For this to happen, the legs should create such a powerful drive that can transfer the energy through […]

As spin is more and more introduced into the game of tennis, there was a lot of confusion how to create a spin in  a most efficient way. By confusion I mean teaching kids to create a lot of spin using their arms solely, seeing lots of kids in a very early age having problems […]
