US Centers for Disease Control and Prevention-Based Physical Activity Recommendations Do Not Improve Fitness in Real-World Settings.

ABSTRACT:

Background

The US Centers for Disease Control and Prevention (CDC) promotes school-based strategies to increase physical activity (PA). Implementation feasibility and effect of these interventions on cardiovascular fitness (CVF) is unknown.

Methods

Forty-nine low-SES schools were randomly assigned to either (1) continue routine PA programs (N = 24 schools, 2399 students) or (2) implement 4 CDC-based PA strategies (N = 25 schools, 2495 students). CVF assessed by PACER (Progressive Aerobic Cardiovascular Endurance Run) was obtained at the beginning and end of the school year. A post-study questionnaire was administered at each school to assess adherence.

Results

Overall, PACER z-scores were not augmented by CDC-based PA strategies. In boys, PACER z-scores increased simi
