Evidence of Effectiveness of School Programs for PA
School-based PA interventions•Increases duration of PA for 5 - 45’/day•Decreases TV time from 5 – 60’/day
•Increases VO2 max
•Participants 3 times more likely to engage in MVPA

Strategies to Increase Physical Activity in Youth
• Implement the Physical Activity Guidelines Midcourse Report
• Mobilize parents• Convene all relevant groups to develop and
implement a strategic plan• Improve the research base that links PA to
behavior and academic performance• Use QRIS, state, and local policies to
implement PA standards in ECE• Engage health providers at all levels in

Parental Support for Physical Education
• A majority believe that PE is as important as other subjects (CDC 2010)
• Over 90% believe there should be more PE in schools (HSPH 2003)
• Over 75% think more PE could help prevent or control childhood obesity (NASPE 2009)
• 95% believe that daily PA helps children do better academically and should be part of K-12 curriculum (NASPE 2003)

National Physical Activity Plan – Strategy 2Tactics
• Binding requirements for Pre K-12 standards-based PE that address curriculum time, class size and employment of certified PE teachers
• Local, state and national standards for high levels of PA in PE
• Federal legislation to require school accountability for the quality and quantity of PE programs
![Page 29: William H. Dietz, M.D., Ph.D. - Keynote - "What Can We Do To Increase Physical Activity in Youth?"](https://reader036.fdocuments.net/reader036/viewer/2022062312/556c7220d8b42ad85e8b5191/html5/thumbnails/29.jpg)
National Physical Activity Plan – Strategy 2Tactics
• Local state and federal funding to assure that schools have the necessary resources, especially for under-resourced schools
• State-level policies to monitor quality and quantity of PA and PE programs
• Require school districts to collect, monitor and track fitness data including BMI

PA Counseling by Pediatricians
• Over 60% of pediatricians and family practitioners ask specific questions about the dose of PA1
• Overweight and obese patients more likely to receive PA counseling2
• Physician’s BMI predicts likelihood of counseling3
