简要总结
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:
- Both groups would improve glucose control, with the CrossFit group improving significantly more than the aerobic and resistance training group.
- Both groups would improve fitness, with the CrossFit group improving significantly more than the aerobic and resistance training group.
- 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.
详细描述
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.

结局指标
主要结局
Change from baseline in glucose control.
时间窗: Baseline, Week 10
Fasting plasma glucose levels were taken after an overnight fast of at least 8 hours. An oral glucose tolerance test was conducted after ingestion of a 75g oral dextrose solution with finger sticks at 30, 45, and 60 minutes from time 0. The following equation was used to calculate glucose area under the curve which was the metric utilized to ascertain changes in glucose control: \[(Time 45 - Time 30) \* ½ (OGTT 30 + OGTT 45)\] + \[(Time 60 - Time 45) \* ½ (OGTT 60 + OGTT 45)\]
