Tennis movement & biomechanics
Real data- Real results.
Instead of a long speech, let’s look at real facts.
A simple power test of the glutes and hamstrings (posterior chain) detected a 14% power deficit in a young player. With this exact data, we immediately rebalanced their physical training program to prevent injuries and unlock maximum speed.

Overview of Tests Used in Injury Prevention
78%
Of injuries are caused by overuse.
What we test ?
- Hand & Forearm Power
- Shoulder Strenght
- Shoulder Mobility & Rotation
How it protects player ?
- Measures grip strength to protect the wrist and elbow from intense training and heavy racket vibration.
- Checks the strength of the rotator cuff and upper back muscles. This balances the shoulder to prevent pain during fast serves.
- Measures how well the shoulder joint moves. Good mobility prevents the shoulder from “pinching” during high overhead hits.
What we test ?
- Hip & Upper Back Flexibility
- Jump Pushing & Landing Balance
- Nervous System Fatigue
How it protects player ?
- Stops the lower back from twisting too much.
- Stops dangerous shockwaves from hitting the spine unevenly.
- Tells us when to rest the player before the core muscles stop protecting the back.

Single-Leg Reactive Split Step (SL-RSS)
As experts in tennis movement, we want to improve our ability to understand and train players.
We all know how important the first two steps are in high-level tennis. It all starts with the split step. That’s why we developed this test.
It can be measured during all types of footwork—forward, backward, and lateral—whether at the start of a point or after 8 or 9 shots, to understand how effort affects the quality of movement.
Track the performance of each shot
When we talk about taking player analysis to the next level—and very few of us do that today—we can combine the two tests. That’s why we need equipment that can be used on the court.
This intelligent system helps us understand how the player moves and, above all, the quality of their shots.
