These can be divided into acute injuries or overuse injuries.
Acute, which can be caused by a direct blow through a collision with another player or equipment, or an injury such as a ligament sprain or muscle tear.
Injuries can involve bone, cartilage, joint, ligament, muscle, tendon, bursa, nerve or skin.
Over use injuries often occur simply by increasing training too quickly. However they may occur due to muscle imbalance, weakness or lack of flexibility.
Treatment needs careful consideration of the onset of injury and a treatment program made suitable to you as an individual.
Once the injury has settled with treatment, rehabilitation should help you gain the confidence and strength to return to your sport.
