Data supports the use of pedometry steps per minute values as an accurate indicator of MVPA. Pedometry demonstrates promise as a viable large-scale surveillance instrument for measuring MVPA in physical education.

Fifth-grade students’ physical activity levels were examined via heart rate telemetry and pedometry during school fitness and recess breaks. Twenty-seven students with a mean age of 11.03 (-.32) years participated in morning recess (MR), lunch recess (LR), and fitness breaks (FB) for three days. Structured FB’s consisted of students engaging in locomotor and nonlocomotor activities within an obstacle course framework, while recess breaks followed a traditional model. Results from repeated measures ANOVAs indicated students engaged in significantly more physical activity during FB than MR and LR. Fitness breaks provided a viable method for increasing children’s school time activity levels.

The findings suggest that engaging in higher volumes of MVPA above 150 min/week and walking, particularly above 60 min/week, are associated with improved HRQOL in people with IBD. Research would benefit from investigating participation in MVPA as a coping strategy, in a longitudinal manner, to determine which modes of activity may be most beneficial to people with IBD.

Background:The aim of this study was to advance physical activity (PA) surveillance in physical education (PE) by establishing a steps/min guideline that would accurately classify fifth and sixth graders as engaging in PA for 10 min or one-third of the PE lesson time.Methods:Data were collected on 147 (11.48 ± 0.83 y) girls and boys in 14 intact classes from five schools. PA was assessed via behavioral observation (i.e., criterion) and pedometry (i.e., predictor). Logistic and linear regression techniques were employed to generate pedometer steps/min cut points. Classification of outcome probability (c), sensitivity, specificity, and receiver-operating-characteristic (ROC) curve statistics tested the decision accuracy of generated steps/min cut points.Results:PA measures were strongly correlated (r ≥ 0.80, P < 0.01). A steps/min interval of 60 to 62 was the best cut point indicator of students meeting the PA guidelines.Conclusions:Findings support steps/min as an accurate quantifier of PA time in structured PA programs. PA surveillance via pedometry in PE using empirically derived criteria is an objective, valid, and practical mechanism for assessing a primary PE and public health outcome.

The objective of the study was to improve physical activity (PA) surveillance of the Healthy People 2010 Objective 22:10 (i.e., 50% of the lesson time engaged in PA) by establishing a pedometer steps/min guideline to quantify time engaged in PA during physical education. A sample of 180 middle school students had their PA measured via pedometry (steps/min) and behavioral observation (PA time). Factorial analyses of variance were used to examine PA differences. Linear and logistic regression, decision accuracy, and receiver-operating-characteristic (ROC) statistics were used to test steps/min cut points against the 50% PA recommendation. PA differences were not found (p > .01). Steps/min was a significant (p < or = .01) predictor of PA time, and the binary outcome of meeting or not meeting the PA recommendation. A steps/min interval of 82-88 was an accurate indicator of the 50% PA recommendation. The ROC statistic was .97 (p < or = .01), suggesting steps/min was an excellent discriminator of the binary outcome. Pedometer steps/min is a valid, objective, and practical approach for surveillance of physical education PA, a key physical education and public health outcome.
