More Time in Gym Class Equals Stronger Kids

Spending more time in physical education classes helps students develop muscle strength and doesn't increase their risk of broken bones, a new study finds. The study included more than 900 girls and boys at a school in Sweden who had up to 200 minutes of physical education a week for two years. A control group of students continued with the standard amount of 60 minutes of physical education each week. The children who had more physical education time developed greater muscle mass and strength than those in the control group, according to the study, published in the May issue of the journal Medicine & Science in Sports and Exercise. http://www.nlm.nih.gov/medlineplus/news/fullstory_136748.html
