Brief Summary

The purpose of this study is to develop and evaluate adaptive goal setting and feedback interventions (Adaptive Interventions) to promote physical activity behaviors and compare it to static physical activity interventions (Static Interventions) using two levels of goal setting (Adaptive Goals vs. Static Goals) and two levels of reinforcement procedures (Praise/Rewards and No Praise/Rewards) in a 2 x 2 factorial randomized controlled trial. All four groups will receive the intervention via a semi-automated text message system developed by the investigators study team. The primary aim of this study will be to:

1. 1.Evaluate whether the adaptive interventions result in greater change in physical activity (pedometer-measured steps/day) compared to the static Intervention groups. HYPOTHESES: Participants in the adaptive interventions will increase their steps/day more than participants in the Static Intervention groups. The Adaptive Goals and Reinforcement Group will outperform the other 3 groups.
2. 2.Evaluate the effectiveness of the adaptive and static goal interventions in improving anthropometric, cardiovascular fitness, and cardiometabolic risk factors. HYPOTHESES: Participants in the adaptive interventions will show greater improvements in fitness, lean and fat body mass, and serum biomarkers than participants in the Static Intervention groups. The Adaptive Goals and Reinforcement Group will outperform the other 3 groups.
3. 3.to assess participants' satisfaction with the overall program.

Outcome Measures

Primary Outcomes (1)

• Change in Fitbit-measured Steps/Day and Moderate-to-vigorous Physical Activity Between Study Arms.

  Given this study used a 2 condition (adaptive vs. static goals) x 2 condition (immediate vs. delayed financial reinforcement) randomized factorial design we report main effects for each condition. Sample sizes for main effects will be 96 participants for each comparison (Adaptive vs. Static goals or Immediate vs. Delayed Reinforcement) as the other condition. Consistent with proper analyses of factorial designs, main effects for the goal setting conditions pool participants across reinforcement conditions, and main effects for reinforcement conditions pool participants across goal setting conditions.

  Daily for 4 months

Secondary Outcomes (5)

• Change in Fitness (VO2max) Between Study Arms.

  Baseline and 4 months

• Changes in Body Mass Index and Body Composition Measured by Dual-energy X-Ray Absorptiometry (DEXA) Between Study Arms.

  Baseline and 4 months

• Changes to iAortic Pulse Wave Velocity Assessed With the SphymocorTM Between Study Arms.

  Baseline and 4 months

• Changes to Cardiovascular-disease (CVD) Risk and Inflammatory Markers (e.g. Glucose, Insulin, Lipids, Adhesion Molecules and Hemostatic Factors) Between Groups.

  Baseline and 4 months

• Changes to Self-reported Physical Activity Measured by the International Physical Activity Questionnaire (IPAQ).
