Sports medicine specialist Dr. Neeru Jayanthi examined the health status of 891 children, including 618 athletes who were being treated for sports injuries and 273 healthy athletes who were getting sports physicals.
Comparing the kids who participated in some form of physical activity for a similar number of hours, the kids involved in more free play were less likely to be injured.
â€œOur findings suggest that more participation in a variety of unorganized sports and free play may be protective of injury, particularly among tennis players,â€ Jayanthi said in a press release. Jayanthi is an associate professor at the Loyola University Chicago Stritch School of Medicine.
Hereâ€™s how it broke down: The 74 kids who played tennis exclusively and got injured spent 12.6 hours per week playing organized tennis and 2.4 hours per week in free play. The tennis players who didnâ€™t get hurt spent 9.7 hours on organized tennis and 4.3 hours in free play.
