Why doesn't my squash ball bounce
All information about the squash ball
Every squash player knows that you have to warm up the squash ball first so that it has the full squash ball bounce. But why is that so? Why doesn't the ball just bounce like a tennis ball or other balls? The answers to these and other really justified questions can be found in the following article.
Where does the bounce of a squash ball come from?
The squash ball is made entirely of rubber, has a diameter of 39.0 to 40.5 mm (comparable to a table tennis or golf ball) and weighs between 23.5 and 24.5 g. Inside it has a cavity that is filled with a drop of liquid gas. Basically, the squash balls are always black, the ball is only white when it is played on a glass court. Before a squash ball is played in, its temperature is also very cool and without internal pressure. When you start to play a squash ball warm, kinetic energy is transferred to the squash ball through the blows. This energy deforms the ball very strongly, which also heats up the ball. As soon as the rubber becomes warmer, the liquid gas that is located in the cavity inside the ball naturally also heats up. As the temperature rises, the liquid gas expands and therefore the pressure inside the ball increases until an overpressure is created and the squash ball bounce increases more and more. The warm-up is not only important for the jumping power, but also for the speed of the ball, the better the ball is warm-up, the faster it will fly. This is so because the increased bounce makes the ball bounce more strongly on your own racket, which allows you to fly faster and more precisely. A squash ball can reach speeds of up to 200 km / h in games between professional players.
Types of squash balls
Of course, every squash ball has its advantages and disadvantages and is more suitable for one type of player than for the other. For example, the blue squash ball is very suitable for beginners and the professionals prefer to use the blacks with two yellow dots in tournaments, but more detailed information on this topic can be found in another article on our site: Which squash ball is right for me?
How do I play a warm squash ball?
The ideal way to warm up a squash ball is to first stand on one side of the playing field and then hit the ball against the side wall with powerful blows. The greater the force with which the ball is played against the wall, the faster it is warmed up to the optimum temperature. However, you shouldn't just stand in one spot, because you should also get warm yourself. It is best if you hit a few balls against the wall, but not only. You should definitely move in all directions while warming up. It would also be important that you warm yourself up a little before doing this with the ball, as a cold ball is heavier on the arm and shoulder joints. Please also note that you play different balls, not just against the wall or the floor, but maybe with a partner, then different hits in the opponent's service court and so on.
Durability of squash balls
As a consumer item, there is of course a loss of playing properties after a while, for example the pressure inside the ball may be reduced or it may be completely damaged. In general, it can also be said that balls with a smaller rebound, for example a ball with two yellow dots, show signs of wear more quickly than a ball with a larger rebound. On average, a squash ball lasts 2 to 3 months (if you play it 3 times a week). However, it also depends on the style of play, with an offensive player the ball usually doesn't last as long as with a technical player. However, the ball should be changed in any case if there are clear cracks on the surface.
We hope we were able to explain clearly and understandably to you where the squash ball jumping power comes from. Now you know why it is so important to warm up the squash ball before the game, how to do it, what types of squash balls there are and how long they last.
