A study in obese men assigned to one of four study groups
(diet-induced weight loss, exercise-induced weight loss, exercise
without weight loss, and control) for 3 mo demonstrated that
VO 2 max improved by approximately 16% in the exercise groups
[5]. Weight loss was 1.3 greater in the exercise-induced weight
loss group than in the diet-induced weight loss group, raising the
importance of the intensity of exercise on the final effects. Blood
glucose levels did not change in the treatment groups compared
with controls; lipid profiles were not evaluated.
