Abstract
Objective. We tested the hypothesis that a combination of diet and either aerobic (DA; N = 11) or resistance (DR; N = 11) exercise would have effects on plasma insulin and glucose levels that were greater than diet alone (DO; N = 9) in upperbody obese men. Research design and methods. Insulin and glucose levels were measured after an overnight fast and following a 75 gram oral glucose challenge (OGTT). Whole body visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT) and skeletal muscle (SM) were measured by magnetic resonance imaging (MRI) pre-and post-treatment (16 weeks). Conclusion. Findings support the hypothesis that moderate weight loss induced by the combination of diet and either aerobic or resistance exercise has effects on OGTT-insulin levels as well as IGAR that are greater than diet alone in obese men. As no treatment differences were observed for reductions in VAT, SAT or total adipose tissue (AT), it is likely that the beneficial effects of exercise are mediated through adaptations in SM known to occur in response to the treatments prescribed.
