Swing Analysis

Without a high-speed video, all coaches and instructors see only the backswing and then follow-through of any stroke. That’s also the extent of what they end up teaching you, because all they know about any stroke this: „take your racket back like this“ and „finish like this“. And where is the rest of the stroke? Is there anyone with knowledge about the rest of the stroke in today's tennis world, who is able to explain often the huge differences in players's performance?

If we use this view and this way of learning, forehands from all ATP players and forehands of the majority of elite juniors would be almost identical.

If they are almost identical to each other, how is it possible that Rafael Nadal and Roger Federer are able to generate up to 5 000 revolutions per minute in their forehands? How is it possible that Nadal is playing his forehands in average 3 200 RPM and players like Sampras played their forehands in average 1 700 RPM. Are the reason modern materials and equipment or an extreme western grips? These and other questions will be answered by SwingAnalyst.

THE DIFFERENCE BETWEEN OUR AND CONVENTIONAL STROKE ANALYSIS

The majority of conventional analyzes presented in today's media, whether websites, magazines, books or coaching manuals, are presented in the form of sequences showing the important body positions that are achieved by the player in the execution of the stroke.

Thanks to high-speed video, we work in our analyzes with at least 200 images, not 5 or 6 images. Compare 6 and 200 images. Because of this limitation, a conventional analysis gives you a very limited view. High-speed video allows us to see precisely the whole movement and we don't need guess what movements precede.

For example, when using a high-speed video, there is no need for debate about how the hand and wrist worked at the time between images in sequence (between the backswing and contact point). We see exactly all movements on the screen. Furthermore, we are regularly able to capture the moments which were random event before high-speed video - the ball in contact with a racket (3-5 miliseconds).

We set for our stroke analysis total of 10 stages. The number of images almost doubled compared to the conventional analysis. With today’s high-speed video many more positions at many more stages during the execution of a stroke can be clearly captured and integrated into the resulting analysis. SwingAnalyst has access to far more information about the body movements involved in any stroke today.

A number of conventional analyzes have already expanded their number of images, but most of them fail to capture the ball in contact with the racket. In addition, the images of these multiple-image sequences are shoot from angles and positions that are unusable for obtaining measurable information.
