A professional development program effectively increased moderate to vigorous physical activity (MVPA) in low-income elementary schools. The intervention boosted daily MVPA minutes for students, highlighting its potential for improving children's activity levels.

Area of Science:

  • Public Health
  • Pediatric Exercise Science
  • Educational Interventions

Background:

  • Schools are mandated to provide 30 minutes of daily moderate to vigorous physical activity (MVPA).
  • Interventions often overlook schools serving low-income populations.
  • This study addresses the need for effective physical activity strategies in underserved schools.

Purpose of the Study:

  • To evaluate a pilot competency-building professional development program.
  • To assess the program's impact on school-day MVPA and total activity in low-income elementary students.
  • To identify effective strategies for increasing physical activity in disadvantaged school settings.

Main Methods:

  • A single-group intervention study with repeated cross-sectional measures.

  • Participatory, experiential professional development for teachers in eight low-income elementary schools.
  • Hip-placed accelerometers measured MVPA, total activity, and sedentary time in 1,570 first and fourth graders.

    • Main Results:

    • Significant increases in the percentage of students meeting the 30-minute MVPA guideline.
    • Boys and girls showed statistically significant increases in daily MVPA minutes during school hours.
    • Improvements in MVPA and total activity were observed across classroom time and physical education.

    Conclusions:

    • Competency-building professional development effectively enhances student MVPA and total activity in low-income schools.
    • The intervention demonstrates a viable strategy for improving physical activity levels in underserved student populations.
    • Future efforts may benefit from targeting settings beyond the school day, as schools already provide substantial MVPA.
