If you're a lover of squash and all things data related, then Racketware is the gadget for you! This handy little device clips on to the end of your racket and uploads all the data you could dream of onto the app via bluetooth.
Specifically looking into the details of your swing? Here's what it all means...
This value is about your racket preparation - getting you racket in position (generally up and back) before you swing. It's given as a percentage: 0% is poor prep with too much prep incorporated into the swing or performed late; 100% is great prep with the racket all set to go in advance of the swing.
Before the swing proper, players often do a loading up motion. This is where the racket head is tipped forward towards the front wall, which helps to create a larger head drop and swing. This value gives you the angle the racket turns through during loading, with 0 degrees meaning that you did not make a loading motion at all.
The head drop is a key part of the swing and is essential for generating good racket head speed. This value gives you the maximum speed you achieved for the head drop.
If your head drop timing is too long, then you are likely to be performing the head drop as part of the racket preparation - too late. Good swings tend to have a nice compact head drop time.
After the head drop the racket should be flat with the elbow leading the swing. The down swing speed is the speed of the racket head during this critical phase.
This is a measure of the speed of the racket head at the point of impact. It is this speed that transfers momentum to the ball.
This tells you if the racket head is speeding up (positive values), is stable (values close to zero), or is slowing down (negative values), at the point of impact. Generally stable values mean that all the energy you have put into moving the racket is being brought to bear on the ball. If the racket is slowing down, then you have wasted energy speeding it up above the speed you eventually hit the ball with. If the racket is speeding up then you are hitting through the ball which is generally good practice. Note that whilst this value is not directly related to the position of the ball at the strike, there may be a correlation.
If the ball strikes the racket away from the line of symmetry that runs down the stem, then the racket will twist when the ball is struck. This value shows how much the racket has twisted on impact, and therefore how far from the centre line the ball was struck. Most players will naturally have some variation here, but if you have a consistent value then you should look at your positioning relative to the ball. Positive values indicate an anticlockwise rotation looking up from the handle of the racket towards the head, and negative values indicate a clockwise rotation.
Many shot are played with a degree of cut in squash (or even topspin occasionally). This value tells you the degree of cut you obtain.
This value represent how quickly you were rotating the racket face around at the point of strike. Good players tend to have a flat approach and a high degree of roll in.
This value is the angle of rotation in the plane of the shot that you get after the strike. The larger the angle, the more you have rotated the racket head around after the strike.
This value tells you the degree of rotation out of the plane of the shot that you get after the strike. If the racket is lifted significantly for example. This value will tell you if you are following through straight through the line of the shot, as opposed to rolling the racket head over and up.
This value gives you the time to the end of the follow through from the strike. If it is too long, you are possibly continuing the follow through into your motion back to the tee, rather than holding for the shot, then moving once complete.
This value is simply the number of shots you are playing per minute.
