Effects of Low Intensity Aerobic Training on Glucose Tolerance in Mildly Obese Young Men
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.21 Vol.21】
Previously, our group recognized that low-intensity aerobic training is effective for improving in insulin sensitivity (SI) and glucose effectiveness (SG), determined by Bergman's minimal model approach, in young non-obese people. The purpose of this study was to see whether the same training is also effective in mildly obese young men. Eight young men, aged 21.6 ± 1.6 years, participated in our 6-week exercise training. Exercise training at lactate threshold intensity was performed for 60 min / day, 5 times / wk for 6 weeks. A frequently sampled intravenous glucose tolerance test was performed pre and post training to determine SI and SG. As a result, aerobic power was significantly improved (p＜0.05), while body weight, body composition, SI and SG were unchanged. These data may suggest that physical training alone is not sufficient to improve SI and SG in obese people, in contrast to non-obese people.
