Probably the most neglected area of the pre game preparation is the warm up. It is recommended to warm-up using the bike, stairmaster or a brisk walk on the track or treadmill for about 5 minutes at a moderate rate. The reasoning behind this is to get the blood circulating to the muscles. This warms the muscles up, allowing you to stretch them.
Injuries often occur from attempts to stretch cold muscles.
Next comes the stretching phase. Since Racquetball uses every muscle in your body, you need a total body stretch before starting your match. Spend extra time on the legs. The reasoning behind the pre-game stretch is to prevent pulling, straining or tearing of muscles, tendons or tissues on the Racquetball court. It is just as important to stretch after playing as before.
