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?
Category: Serve
PREPARATION PHASE
What is preparation phase? Placing the ball in the air while the body is getting ready to store the energy (cocking phase) in the most efficient way for the throwing motion (acceleration and follow through phase).
Significance of the LEG DRIVE in the efficiency of the serve motion
What is leg drive?
The first link in the kinetic chain motion of the serve, using the ground reaction forces as the player push off the ground and its efficiency depends on the coordinated and synchronized extension of three joints (starting from the ankles to the knee joints and then to the hip joints)
Linear and Angular momentum in the serve motion
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
