TENNIS GAME – THE GAME OF MOMENTUMS

Momentum measures the ‘motion content’ of an object and is based on the product of an object’s mass and velocity. For players to perform accurate strokes with high velocity, there should be an optimal combination of linear and angular momentum. The optimal combination depends on the urgency of movement, level of balance, perception of the situation and even level of confidence. With a creation of a larger momentum, greater forces and abilities are required from a hitter to decelerate to set up and execute a successful stroke

I would like to use the scientific approach to tennis and bring it in the easiest form to the tennis coaches around the world.

Understanding the movement patterns of the expert players can provide many data which we should use when developing tennis players.

These data showed that the more expert player is skilled in disguising his stroke intentions the more he places opponent to the disadvantageous position. Something worth to think about when talking about technical-tactical aspect of the tennis teaching

SPLIT STEP AIR PHASE

One of the greatest challenges of the dynamic tennis environment is a creation of a quick and accurate decision of the physical response (movement) corresponding to the technical-tactical intentions of the opponents’ striking actions. By prioritizing the needs of high-speed reactions, expert tennis players tend to decide of the movement direction and intensity while still being above the ground, at the air phase of the split step, as proposed by Uzu et al. (2009). From there the decision of the movement intensity and direction corresponds to receiver gathering information while increasing the much-needed muscle spindle sensitivity of the leg muscles before the ground contact, moving their center of mass away towards the edges of their support base.

ストロークのバイオメカニクス：位置エネルギーから運動エネルギーへの移行

テニスでは、プレーヤーはテニスラケットを使って体からボールにエネルギーを伝達し、ボールのスピードとスピンを生み出します。負荷されたエネルギーは、潜在的なエネルギー（蓄積されたエネルギー）であり、運動連鎖を介して、体節の移動エネルギー（運動のエネルギー）に、インパクトゾーン全体でタイムリーに、望む方向に伝達されます。
