Overuse injuries develop from repetitive stress and are common in sports such as running and tennis. Unlike traumatic injuries (for example, a sprained ankle), overuse injuries cannot often be pinpointed to a single event. Research shows that psychosocial factors play a role in the development of overuse injuries. Individual factors such as competitive drive, perfectionism, and dependence on one’s athletic identity influence risk for overuse injury, as do interpersonal factors, such as coach-athlete relationship.
