- Brief Summary
The purpose of this study was to test the efficacy of a fitness- and behavioral-focused intervention, Athletes for Life (AFL), to improve cardiorespiratory fitness (CRF) among 160 underserved families.
- Detailed Description
The Athletes for Life (AFL) study was a 12-week randomized controlled trial designed to promote cardiorespiratory fitness (CRF) and healthy lifestyle changes among parents and children. The original enrollment target was 160 families. A total of 149 parent-child dyads living in a Southwestern U.S. metropolitan area were enrolled in the study. AFL consisting of 24 structured, twice-weekly 90-min family-based, nutrition and sport/fitness-oriented sessions, and was delivered in a municipal recreation center. Behavior change, including increased physical activity, and adherence were motivated through positive reinforcement techniques. Families were randomized to either the AFL program or a wait-list control group.

Group Intervention Description Wait-List Control Group Wait-List Control The wait-list control group received the 12-week AFL intervention after all follow-up data had been completed. AFL Intervention Group AFL Intervention The AFL intervention consisted of twice a week physical activity and nutrition sessions for children and twice a week educational and physical activity sessions for parents. Each session lasted 90 minutes and all sessions were conducted in a municipal recreation center. The child program was delivered in English while the parent program was delivered in separate English-only or Spanish-only classes.
