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
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
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.
IN THE NEXT TWO POSTS WE WILL EXPLAIN WHY SPLIT STEP IS NOT SIMPLY MUSCULAR REACTION. AS ITS A PREPARATORY STEP, THE NEUROLOGICAL ASPECT IS OF HIGHEST IMPORTANCE IN PREPARING THE MUSCULAR SYSTEM TO CREATE TIMELY AND ACCURATE RESPONSE
