Strains - A strain is a partial or complete tear of a muscle or tendon. Muscle tissue is made up of cells that contract and make the body move. A tendon consists of tough connective tissue that attaches muscles to bones. Contusions - The most common sports injury is a contusion or bruise.
Bruises result when a blunt injury causes underlying bleeding in a muscle or other soft tissues.
Skeletal Injuries Skeletal injuries - A sudden, violent collision with another player, an accident with sports equipment, or a severe fall can cause skeletal injuries in the growing athlete, including fractures. Fractures constitute a low 5 to 6 percent of all sports injuries. Most of these breaks occur in the arms and legs. Rarely are the spine and skull fractured. Stress fractures occur frequently because of continuing overuse of a joint.
