Rest to Avoid Overuse
An estimated 50 percent of pediatric sports injuries are related to overuse. These types of injuries are more common in children who take part in two or more sports that put strain on the same body part. Overuse injuries usually cause tendonitis—of the knee or elbow, for example.
Kids should have about two days off from sports per week, as well as a 10-week hiatus from any particular sport each year. In addition, they should get a rest break during practices and games.
