Theoretical Model to Improve Health & Academic Achievement

Schools are Sedentary
• Bus ride can be > 60 min each way• Recess and physical education has declined to
levels that cannot provide adequate stimulus (energy expenditure) for fitness or to protect against fatness
• Motor time off task is discouraged and disciplined
• Traditional teaching paradigm- sit down and be quiet
![Page 6: Joseph E. Donnelly - "Physical Activity and Academic Achievement in Elementary School Children"](https://reader035.vdocument.in/reader035/viewer/2022062303/55620bccd8b42a00138b495c/html5/thumbnails/6.jpg)
Physical Education by Itself is not Adequate to Provide Fitness or Prevent Fatness in the
Current Environment• PE and recess have diminished, frequently
offered 2-3 X week• PE duration as little as 20 minutes• MET value frequently just at or below the
definition of moderately vigorous• Inadequate facilities & equipment• PE teacher shared among schools, poor
training/no training

Physical Activity Across the Curriculum (PAAC)
A 3-year, randomized controlled trial of physical activity and academic
achievement for elementary school children in grades 2 & 3
Donnelly et al., Physical Activity Across the Curriculum (PAAC): A randomized controlled trial to promote physical activity and diminish obesity in elementary school children.Prev. Med. 2009, 49:336-41 (DK61489)

Major Aims of PAAC
• Increase physical activity by using classroom teachers to teach existing lessons with using physical activity
• Primary aim-Diminish increases in BMI
• Secondary aims-Determine association between physically active
lessons and academic achievementCharacterize metabolic syndrome
![Page 9: Joseph E. Donnelly - "Physical Activity and Academic Achievement in Elementary School Children"](https://reader035.vdocument.in/reader035/viewer/2022062303/55620bccd8b42a00138b495c/html5/thumbnails/9.jpg)
The PAAC Program
•A classroom-based approach to reduce sedentary behavior while maintaining the focus on academics
•NO DECREASE in academic instruction time
•PAAC is a technique to deliver existing academic instruction through movement
![Page 11: Joseph E. Donnelly - "Physical Activity and Academic Achievement in Elementary School Children"](https://reader035.vdocument.in/reader035/viewer/2022062303/55620bccd8b42a00138b495c/html5/thumbnails/11.jpg)
Conceptual Framework
• Minimal intervention• Enhances learning• No additional teacher preparation time• No additional cost• Easily perpetuated and replicated• Desirable for both teacher and student (i.e.,
FUN)• Students “must” participate in classroom lessons
![Page 12: Joseph E. Donnelly - "Physical Activity and Academic Achievement in Elementary School Children"](https://reader035.vdocument.in/reader035/viewer/2022062303/55620bccd8b42a00138b495c/html5/thumbnails/12.jpg)
The PAAC Program
Integrate 10 minute periods of physical activity within academic lessons for a total of 90 min/wk (i.e. 1 ten min lesson in morning and afternoon.

Design
• Cluster randomized, controlled trial N=22• 3 year intervention• Grades 2&3• Target 90 minutes of moderate to vigorous
physical activity/wk• Use classroom teachers to deliver existing
academic lessons using physical activity

A+PAAC Design- Emphasis on Academic Achievement
• Adequately powered, cluster randomized trial• 17 elementary schools, (9 intervention, 8
control)• ~ 20 children from 2nd & 3rd grades followed 3
yrs. to 4th and 5th grades (~40/school, 682 children total)
• 20 minutes of A+PAAC lessons/day

A+PAAC Outcomes
• Academic achievement measured by Wechsler Individual Achievement Test III
• State administered achievement tests with individual identifiers
• Cognitive function- Flanker, n-back (Hillman)• Anthropometrics, fitness (Pacer), blood
chemistry, blood pressure, attention-to-task (Mahar), energy expenditure of A+PAAC lessons (indirect calorimetry via CosMed)

Relationship Between Fitness and WIAT III
Significant association between fitness and math controlling for grade, gender, BMI, mother’s education, household income and intraclass correlations among classes and schools

How to Increase Physical Activity in Schools Without Decreasing Academic Instruction
• Increase time children are physically active in current physical education and recess
• Provide access to physical activity before and after school
• Promote active transportation• Provide physically active lessons
![Page 28: Joseph E. Donnelly - "Physical Activity and Academic Achievement in Elementary School Children"](https://reader035.vdocument.in/reader035/viewer/2022062303/55620bccd8b42a00138b495c/html5/thumbnails/28.jpg)
What is Needed to Avoid Barriers and Promote Non-Traditional Physical Activity
in Schools • Low teacher burden for lesson preparation• Activity disconnected from motor skills• Additional evidence to link physical activity/fitness
& learningPlausible biological model combined with evidence
from well designed interventions linking to state academic achievement tests
• Low cost/no cost, sustainable programs through university teacher preparation (i.e., additional cost = $0.00)

A+PAAC Concept Lessons
MATH ELAPSED TIME – LUNGES, JUMPS, & JUMPING JACKS
The students are in a standing position and hopping in place off of both feet. The teacher gives them a problem involving “elapsed time.” For example, the movie started at 5:00 pm and ended at 8:00 pm. How much time passed? Students continue hopping and give a verbal answer. If the answer is correct, the students are asked to do 3 lunges, each lunge representing 1 hour. Variation: The elapsed time could be in 30 minute periods or 15 minute periods. Jumps and/or jumping jacks would be good movements for this variation. (1 jump or 1 jumping jack = 1 minute)

Evidence for Physical Activity & Academic Achievement
• Fitness (aerobic capacity) seems to be associated with academic achievement
• Academic lessons taught with physical activity have been shown to improve academic achievement and attenuate increases in BMI (2 for 1) even without increases in fitness
• Physically active lessons may improve attention-to-task, a behavior associated with learning, and critical to classroom management
There is no evidence that removal of physical activity programs results in greater academic achievement
