Studies show almost one-third of all injuries incurred in childhood are sports-related. The most common are sprains and strains.
Doctors at Children's Hospital of Philadelphia say they still see anything from concussions to overuse injuries, like stress fractures.
Dr. Michael Beasley, a pediatric sports medicine specialist, says it's important to have a gradual return to an active fall from a low-key summer.
Stretching before sports and other activities warms your muscles up, and stretching after a practice helps build strength and endurance, Beasley adds.
It's also important to avoid unhealthy comparisons between other student-athletes.
Beasley says rest days are just as important in making sure student-athletes hit peak performance.
