Abstract	Schools have been identified as primary societal institutions for promoting children's physical activity (PA); however, limited evidence exists demonstrating which traditional school-based PA models maximize children's PA. Purpose: The purpose of this study was to compare step counts and moderate-to-vigorous physical activity (MVPA) across 4 traditional school PA modules. Method: Step count and MVPA data were collected on 5 consecutive school days from 298 children (Mage = 10.0 +/- 0.6 years; 55 percent female) in Grade 5. PA was measured using the NL-1000 piezoelectric pedometer. The 4 models included (a) recess only, (b) multiple recesses, (c) recess and physical education (PE), and (d) multiple recesses and PE. Results: Children accumulated the greatest PA on days that they had PE and multiple recess opportunities (5,242 +/- 1,690 steps; 15.3 +/- 8.8 min of MVPA). Children accumulated the least amount of PA on days with only 1 recess opportunity (3,312 +/- 445 steps; 7.1 +/- 2.3 min of MVPA). Across all models, children accumulated an additional 1,140 steps and 4.1 min of MVPA on PE days. Conclusions: It appears that PE is the most important school PA opportunity for maximizing children's PA. However, on days without PE, a 2nd recess can increase school PA by 20 percent (delta = 850 steps; 3.8 min of MVPA). Verf.-Referat.
