Summary

The purpose of this study was to examine the differences in glucose control, fitness, and body composition between a standard aerobic and resistance exercise training program and a shorter-duration, high-intensity CrossFit training program in overweight and obese physically inactive adults. Hypotheses: 1. Both groups would improve glucose control, with the CrossFit group improving significantly more than the aerobic and resistance training group. 2. Both groups would improve fitness, with the CrossFit group improving significantly more than the aerobic and resistance training group. 3. Both groups would demonstrate decreases in body fat percentage and fat mass and increases in lean body mass, with the CrossFit group improving significantly more than the aerobic and resistance training group.

Detailed description

Overweight or obese participants will take part in an 8-week exercise intervention after clearance from a doctor, that is expected to improve glucose control, fitness (Eurofit and peak aerobic capacity), and body composition (body fat percentage, fat mass, and lean body mass). After stratification by age and body mass index, participants will be randomized to either a standard aerobic and resistance training exercise program or a relatively higher intensity, shorter duration CrossFit exercise program.

Conditions

• Hyperglycemia

Interventions

Type	Name	Description
OTHER	High-Intensity Functional Training	Participants were instructed to work as hard as they could while maintaining safe technique and proper form to achieve as many reps or rounds as possible in the prescribed time frame. As HIFT participants became accustomed to specific movements, less time was dedicated to practicing movements and technique.
OTHER	Aerobic and Resistance Training	The protocol was based upon current guidelines of 150 minutes moderate-intensity aerobic activity and 2 days of muscle strengthening per week.
