In order to keep lateral momentum as a source of power, the player needs to keep the inertia (lateral direction) without pulling the breaks before the stroke transferring the linear momentum into the forward momentum

PRINCIPLES OF THE EFFICIENT MOVEMENT and PERFORMANCE
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
