Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Families (i.e., children and parents/primary caregivers dyads) were randomly assigned to participate in either the intervention group or a wait-list control group. The intervention (AFL) consisted of 24 structured, twice-weekly 90-min family-based, nutrition and sport/fitness-oriented sessions, and was delivered in a municipal recreation center. The wait-list control group received the intervention after all follow-up data had been collected. Data from all participants (both intervention group and wait-list group) were collected in four phases: before the intervention group started the program (week 0) and at 6, 12, and 24 weeks, thereafter.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

AFL Intervention Group

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.

Group Type EXPERIMENTAL

AFL Intervention

Intervention Type BEHAVIORAL

The AFL intervention consisted of two 90-minute sessions per week for 12 months for both children and parents. The child physical activity sessions, held separately from the parent sessions, aimed to achieve 60 minutes of moderate-to-vigorous physical activity during each session through structured play activities, athletic drills, and sport exercises. Child dietary behaviors were taught through educational activities in small groups. For the parent program, behavior modification techniques were used to guide parents toward changing their own and their child's behavior. Take-home materials for self-monitoring of behaviors were used for both the child and the parent in order to reinforce concepts discussed in class.

Wait-List Control Group

The wait-list control group received the 12-week AFL intervention after all follow-up data had been completed.

Group Type OTHER

Wait-List Control

Intervention Type BEHAVIORAL

Families that were randomly assigned to the wait-list control group were asked not to change their normal physical activity or dietary behaviors for the duration of the 12-week waiting period. They were asked to participate in the baseline and 12-week evaluations and then they were enrolled to receive the 12-week intervention.
