  1. a Overweight treatment groups (control group, exercise 150 min/wk, exercise 300 min/wk) enrolled in the weight gain prevention study were significantly different from overweight/obese treatment group (exercise 200 min/wk) enrolled in the weight loss study at p < 0.01(**) or p < 0.05(*) due to recruitment of slightly different study populations for the two randomized clinical trials.
