Physical Activity Program

Physical Activity Trends

Physical activity is a healthy practice that strengthens muscles and bones, improves the pumping ability of the heart, boosts the immune system, and strengthens nearly every other system of the body. Physical activity may include brisk walking, running, playing basketball, and even activities like pushing a stroller, housecleaning, and gardening.

The following chart shows data obtained from the Youth Risk Behavior Surveillance Survey (YRBSS) on the percentage of children (grades 9-12) in the United States and Arizona who met physical activity recommendations in 2005 and 2007.
