A simple way to analyze the tennis movement and footwork quality of a player is to record parts of their training session using Swingvision. https://swing.vision/r/feeltennis
The green dots on the diagram represent the positions from where the player played the forehand, while the orange dots show the positions from where the player played the backhand.
If there are too many orange dots on the right side of the diagram, it indicates that the player was not moving around the ball and being lazy. To improve footwork, it is important to push the orange dots to the left and have more green dots on the right side of the diagram.
This is just one simple example of how you can use SwingVision to track the quality of your tennis practice sessions. You can use your creativity to come up with more ideas on how to best measure the quality of training with SwingVision tracking ability.
