WASHINGTON, May 23 (Reuters) – U.S. schools need to boost
efforts to get students moving, and make gym class as critical
as other core subjects if they want to increase test scores as
well as students’ general well-being, a leading group of health
advisers said on Thursday.

The Institute of Medicine called for younger students to get
at least 30 minutes of physical activity per day in school and
older students 45 minutes, with at least half that time spent
moving vigorously.
