Fat Oxidation Rate During and After Three Exercise Intensities in Non-Athlete Young Men

The purpose of present study was to compare fat oxidation rate during and after three different exercise intensities. Eight non-athlete male students (aged, 19.7±1.8 yr; height, 174.3±5.1 cm; weight, 64.5±7 kg; VO max, 40.1±4.4 ml/kg/min) participated in this study as subjects. Each subject was exercised at 55, 65 and 75% 2 VO max on treadmill at three separate days those days which elapsed by at least one week. Experimental 2 protocol consisted of a 15 min pre-exercise resting period, 60 min exercise period and 2-h recovery period. Indirect calorimetry was used throughout the experimental protocol to measure fat oxidation rate. The ANOVA with repeated measures and Bonferroni were employed to compare fat oxidation rate during and after different exercise intensities. The results of present study showed that absolute fat oxidation rates during and after 75% VO max and also total absolute fat oxidation rates were significantly higher than other intensities (P 0.05). 2 Relative fat oxidation rate during 55% VO max was significantly higher than other intensities (P 0.05), but 2 relative fat oxidation rate and total relative fat oxidation rate were not significantly different after three exercise intensities. Energy expenditure during 75% VO max and total Energy expenditure were significantly higher than 2 other intensities (P 0.05). It was concluded that exercise with 75% VO max can be beneficial to reduce and 2 maintenance of the weight.
