Blisters form when the skin is exposed for extended periods of friction and pressure. For tennis players, the handle of the racquet is a common cause of blisters on the hands and fingers. The rackets generate blisters mainly by the rubbing that occurs with the hand. A classic match includes hundreds of punches and even small turns of the racquet in the hand can cause blisters.
Select the size of the correct grip when you choose a tennis racquet. The sizes of the handles are measured from the center of the palm of the hand to the tip of the ring finger. This distance, in inches, is equal to the size of the correct grip. If you are choosing the size of a grip, choose the smallest you can adjust using “over grips” or a tape on the grip.
Use a new over grip for each game. As you play, the tackiness of the grip deteriorates, due to this it will be more complicated to cling to the racket and avoid slipping. When sliding the handle generates friction and eventually blisters. An over grip placed on top of the grip of a tennis racquet provides a sticky grip that is lost little by little.
Dry the grip and your hands with a towel between play and game. A wet grip is more difficult to retain and stimulates sliding and friction.
Use a band that stops the sweat on your forearm to prevent it from wetting your arm and your hand during the game.
Put on a padded bandage on areas that start to get irritated.
Try different types of over grips to identify which one is most appropriate for you.
Do not leave an injured blister during the game. A sore blister is like an open wound and is prone to infections.
