Summary
Classroom-based physical activity (PA) interventions provide equal steps for boys and girls. This classroom activity also helps older students maintain their activity levels, reducing grade-level differences.
Area of Science:
- Pediatric Health
- Exercise Science
- Educational Interventions
Background:
- School physical activity (PA) interventions show positive effects, but research on variations in scheduled PA and classroom-based PA (CBPA) impact is limited.
- Understanding how different PA opportunities influence student outcomes is crucial for effective health promotion in schools.
Purpose of the Study:
- To examine the effects of scheduled PA opportunities (physical education, recess) and teacher-implemented CBPA on elementary students' daily step counts.
- To investigate potential gender and grade-level disparities in PA outcomes related to these interventions.
Main Methods:
- Teachers received CBPA training across 5 elementary schools.
- School-day PA data (PE, recess, CBPA) were collected via calendars and logs.
- Student daily step counts were measured using accelerometry in 1346 students (grades 1-5).
Main Results:
- Physical education, recess, and CBPA significantly contributed to daily steps.
- Males accumulated more steps than females during PE and recess, but not during CBPA.
- CBPA participation minimized the decline in step counts observed in older students.
Conclusions:
- Classroom-based PA (CBPA) offers equitable PA benefits across genders.
- CBPA may mitigate age-related declines in physical activity among elementary students.
- Integrating CBPA into the school day can help address disparities in student activity levels.
