Abstract

BACKGROUND: Effective and scalable interventions are needed to combat chronic low levels of youth physical activity. After-school sport sampling programs may be vital interventions for teaching sports and increasing physical literacy and physical activity, which result in healthy lifelong habits that are maintained into adulthood.

OBJECTIVE: The purpose of this study was to test the effectiveness of an after-school sport sampling intervention among underserved youth in the Midwest.

METHODS: Youth (n=81) in 3 middle schools within a large Midwest city participated in an 8-month, after-school physical activity intervention that aimed to increase moderate- and vigorous-intensity physical activity, improve physical literacy, and decrease BMI. Difference scores for this 2-group, posttest-only design were calculated. A series of 2-tailed t tests were conducted to assess between-group differences.

RESULTS: The intervention group had significantly better physical literacy (t(115)=7.57; P=.004) and engaged in more moderate- and vigorous-intensity physical activity minutes per week (t(115)=4.28; P=.04) and steps per day (t(115)=4.29; P=.03).

CONCLUSIONS: An after-school sport sampling program may be an effective solution for combating youth physical inactivity. Future research should assess the scalability of this intervention with larger populations and in different areas.
