  2. Purpose of the Study • To determine how many of the recommended physical activity minutes are being met by children each day/week during school based settings • To determine who is meeting those recommendations • To determine what intensity of physical activity is required each day/week to achieve health benefits measured by the Fitnessgram Assessment Battery • To determine what is the dose response curve for accumulated activity/intensity to give maximal health benefits

  3. Methods • All CWIP schools servicing 4th grade populations were invited to participate. • At participating sites the Physical Education teacher and/or administrator were trained in study protocol and the use of HRM’s • Information letters and parental consent forms were sent home with fourth grade students from volunteer classroom teachers • Participating students were trained in study protocol and assigned a HRM • 116 4th grade students were trained, data was collected during physical education and recess on 92 students • Data was collected from three CWIP schools and one non-CWIP school over a nine week period • Data was transferred from the Polar RS400 watch to the PROTRAINER 5 Software • Data was analyzed using Linear Regression • P.A. and change in Cardiovascular Strength/Endurance scores, Muscular Strength/Endurance Score • P.A. and change in Flexibility score, and Body Composition

  7. Conclusions • CWIP Schools Averaged 364.66 minutes per week; Non-CWIP School Average 250.09; Average for all schools about 307 minutes a week • Intensity Averages: 50%=155 minutes; 60%=194 minutes;70%=207 minutes; 80%=192 minutes (Mean=83 minutes of MVPA a Week) • Mean equates to 15% of variance in C.V. Scores (R2=.151 p>.01) • Mean equates to 8% of variance in M.S Curl-Up Scores(R2 =..075 p>.016) • No significant relationship in P.A. and Flexibility or Body Composition Scores • On average, girls spent 15% less time in zones 3 and 4 (50-79% MHR) than boys
