Abstract
OBJECTIVE:
To describe the prospective relationship between physical activity and academic performance.
DATA SOURCES:
Prospective studies were identified from searches in PubMed, PsycINFO, Cochrane Central, and Sportdiscus from 1990 through 2010.
STUDY SELECTION:
We screened the titles and abstracts for eligibility, rated the methodological quality of the studies, and extracted data.
MAIN EXPOSURE:
Studies had to report at least 1 physical activity or physical fitness measurement during childhood or adolescence.
MAIN OUTCOME MEASURES:
Studies had to report at least 1 academic performance or cognition measure during childhood or adolescence.
RESULTS:
We identified 10 observational and 4 intervention studies. The quality score of the studies ranged from 22% to 75%. Two studies were scored as high quality. Methodological quality scores were particularly low for the reliability and validity of the measurement instruments. Based on the results of the best-evidence synthesis, we found evidence of a significant longitudinal positive relationship between physical activity and academic performance.
CONCLUSIONS:
Participation in physical activity is positively related to academic performance in children. Because we found only 2 high-quality studies, future high-quality studies are needed to confirm our findings. These studies should thoroughly examine the dose-response relationship between physical activity and academic performance as well as explanatory mechanisms for this relationship.
