  • In 2013, only 29% percent of high school students had participated in at least 60 minutes per day of physical activity on each of the 7 days before the survey.3 
  • 15.2% percent of high school students had not participated in 60 or more minutes of any kind of physical activity on any day during the 7 days before the survey.3
  • Participation in physical activity declines as young people age.3
