It would be very useful after training tennis shots to immediately see the results. Also I would like to see how my shots are developing over time.

Helper questions

  1. What kind of services are available to provide feedback about tennis shots?

  2. What kind of tools are coaches using?

  3. Is there some tool that could be used alone?

  4. Does there exist any training management program that stores and helps manage the recordings?

For more technical questions, please read Apple-oriented question here and more photography-oriented question here.


1 Answer 1


I haven't found any technical tool under "indepedent training management" rather mechanical innovations. Firstly, soft ball slows down the features of the ball such as spinning so easier to analyse. Secondly, different field materials help you to understand the behaviour of ball such as spin. Thirdly, a hit wall makes it far faster to trial-and-error different shots because you get an immediate feedback after the rebound.

I tested the stroke-analysis iPhone app but it is far too slow. I haven't found any technical tool to help me here but below the mechanical ways to get feedback about the shots independently.

I. Soft ball

I have used a soft Wilson ball by which you can see profile of the ball easier. This is because the soft ball reacts slower to all hits so you have time to analyse it.

II. Different field materials

Spins have different behaviour in different fields such as Matta (Finnish) and Hiekkanurmi (Finnish). Matta, the red clay mixture, reacts the most for spins so a good way of seeing how much each shot has spin.

III. Hit Wall with different angles

  • A ball with topspin after the 180 degrees deflection will act as a ball with backspin after collision.

  • A ball with backspin after the 180 degrees deflection will act as a ball with topspin after collision.

And about the recordings to better see the technique

Whenever possible, ask your subjects to wear as little as possible, or in the least, have them wear tight clothing that will not mask the true motion of the body. It can be very difficult to analyse motion if athletes are wearing baggy clothes. Another way of improving the repeatability of measures taken from video is to use markers attached to various anatomical landmarks on the body. Even using a permanent marker to draw on subjects’ skin can improve the repeatability of measures taken from a video analysis.
