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

What my Doctoral Thesis Taught me: Tennis Training for the Future Champions

Coaches teach tennis from the point of “racquet-ball” rather than movement and timing. Interception has two aspects, movement towards the ball to intercept it and create an impact point. This can differ from the concept of the hitting in which player can wait for the ball to approach before the impact. Even with the perfect contact point in which the ball lands at the string bed at the sweet spot, if the momentum of the hitter’s racquet movement does not match the movement momentum of the incoming ball, the stroke will not be satisfactory in intensity and direction

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

打撃姿勢がフォアハンドのメカニックに与える影響

脚と体幹の質量が大きい低速筋群は、前進する腰へのエネルギー伝達の主要な源であるレッグドライブとして、直線的な運動量に大きく寄与しています。大きな筋肉群が前方への運動量に大きく寄与するという概念から、効率的なレッグドライブを生み出すバッターの能力に関する観察者の認識は、ストロークの意図を予測する上で重要な情報を提供することができます。体幹の回転は、外旋負荷の角度によって、ボールの方向とペースについて非常に有益な情報を提供することができます。オープンスタンスに比べ、スクウェアスタンスでのストロークでは、腕の内旋とトルクの値が著しく高くなり、ボールの攻撃性と貫通性に寄与することが研究により明らかになった
