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
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.

ANTICIPATION IN TENNIS AND WHY TENNIS CHAMPIONS ARE CHAMPIONS
Through the course of tennis history, players’ performance enhancement evolved around the strokes and its effective application for the purpose of winning points in the competitive environment. Players’ stroke execution is surely one of the most researched field in the game of tennis as all tennis players, no matter of the level of their game or competitive involvement, are mostly attentive to the stroke mechanics and consistency of their body parts movement in space and time. Players usually try to be mostly aware of their own hitting space, with a tendency to underestimate the fact that tennis is a game of movements and interactions.
BRAIN FUNCTIONS and OUR PERFORMANCE
To be able to produce consistent level of performance at the physical (visible to eye) level, athletes are in need of the rested and productive brain, prepared to create mental images and connect them to the muscle fibers producing the most optimal movement
PERCEPTION IN TENNIS AS AN EARLIEST ASPECT OF THE TENNIS MOVEMENT
Visual system is the dominant sensory system and critical for detecting relevant cues for an appropriate motor response. As such, for successful performance, an athlete, especially in tennis, must identify and attend to relevant visual cues as early as possible
HOW HITTING STANCE INFLUENCE THE MECHANICS OF YOUR FOREHAND
Direction of the stroke is related to the timing and angle of the impact point. The unwritten rule is that the ball will be following the direction to which strings of the racquet are directed to at the point when racquet intercepts the ball. Usually, in order to perform at their best, the players change timing of torso rotation to the ball while changing direction of the stroke
SPECIFIC TENNIS MOVEMENT TRAINING
The movement as a task and its outcome can be influenced by multiple factors as players interact with environment adjusting, creating and coordinating their own psycho-physical responses and body movements depending on the task in hand (perception) and spatio-temporal constraints (action potentials)
OUR HIGH PERFORMANCE PROGRAM
OUR HIGH PERFORMANCE PROGRAM DESCRIPTION.
WE ARE PROUD OF OUR WORK WITH NATIONAL PLAYERS, KANTO PLAYERS and HIGH SCHOOL CHAMPIONS in JAPAN
Counter attacking movement
Initiating preparation for the stroke that is considered defensive not only influences the stroke mechanics but decreases the levels of forces used in the stroke production. By changing the perception from defensive to counter attacking, the player can neutralize the attacking intentions of the opponent, placing him/her to the unfavorable position at the court
LATERAL MOVEMENT IN TENNIS
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
Attention in tennis.Transition from external to internal focus of attention
Creating the mental projections of future movement, before the physical response is initiated, is always dependable on the dynamic changes of the environment to which we have to be attentive constantly in order to adapt efficiently

Quantifying training load series – Importance of understanding the concept of an individualization
Quantifying the training load and measuring it helps the coaches and athletes to understand the process progression at the practice and during or after the tournament. Information about the progression is crucial as the coach can understand which of the practice elements the athlete has already implemented successfully into the game. Systematically monitoring the physiological and psychological changes of the athletes’ performances, helps to determine the effectiveness of the practice and based on that to analyze the efficiency of the training program
Tennis Skill Acquisition and Long Term Development
We are not teaching tennis players to be automative machines but intelligent athletes that can recognize and adapt to the constantly changing environment. From acquisition to stabilization phase, we can not teach technical skills separately from the tactical skills
