physical exercise

Even though adolescents spend less than 5 percent of their time at school engaging in physical activity, according to a new study, such time accounts for almost half of their overall exercise, and was still 20 minutes than the amount experts recommend.

Parents who believe that their kids are getting enough physical exercise just from playing organized sports may be in for a surprise.  A new study finds that, though participation in youth sports contributes to overall physical activity, fewer than one fourth of youth soccer, baseball and softball players studied obtained the sixty minutes a day of moderate to vigorous physical exercise (MVPA) during sports practices that U.S. guidelines recommend.
