| Research Abstract |
In order to clarify the effect of resistance training to fat oxidation and daily physical activity the following experiments were performed.
Study 1: Fat oxidation and daily physical activity in resistance-trained men In body builders and a power lifter, energy metabolism including 24-h fat oxidation and energy expenditure was evaluated using indirect human calorimeters, and total energy expenditure and physical activity level in free-living conditions by doubly labeled water method, and the results were compared with healthy controls. In the group of body builders and a power lifter, higher physical activity was observed. However; there was no significant difference in the other measurements including 24-h fat oxidation, after adjustment for body composition.
Study 2: Effect of resistance training to fat oxidation and physical activity Effect of resistance training for 12 weeks to fat oxidation and physical activity in university students was evaluated. 24-h fat oxidation and energy expenditure were evaluated using indirect human calorimeters, and total energy expenditure and physical activity level in free-living conditions by doubly labeled water method. No significant change was observed in most of the measurements, although total energy expenditure slightly increased in the intervention group.
These case-control and intervention studies revealed that fat oxidation may not significantly change by resistance training, while physical activity level was higher in resistance-trained athletes, probably due to their occupations.
