Sports injuries are physical injuries that occur during sports or exercise. They can range from minor to severe, and include sprains, strains, fractures, dislocations, contusions, abrasions, ligament tears and concussions. Treatment of sports injuries depends on the severity of the injury, but typically includes rest and rehabilitation exercises. Prevention of sports injuries is important in order to reduce the risk of further damage or re-injury. Protective gear such as helmets and pads should be worn when playing contact sports or engaging in activities with a high risk of injury.
