Effects of the Aerobic Exercise Types of the Same Amount of Exercise on the Energy Metabolism During Exercise and Recovery Phase

OBJECTIVES The purpose of this study was to investigate the effects of aerobic exercise types on energy metabolism during and after exercise under the same exercise volume conditions.METHODS Ten healthy men were randomly assigned to interval(IV), intermittent(IM), and continuous(CO) exercise, and the experiment was conducted at intervals of one week and consumed 300 kcal. The data were verified by repeated measurement one-way ANOVA, and contrast was conducted. The statistical significance level was set at α=0.05.RESULTS As a result of the study, first, among the energy metabolism variables during exercise, oxygen intake(VO2) was statistically significantly higher in the IM and CO exercise than in the IV exercise(p<0.001). The respiratory exchange rate(RER, p<0.001), energy consumption per minute(ECM, p<0.001), and carbohydrate consumption amount(CCA, p=0.013) were significantly higher in the IM exercise, but there was no statistically significant difference in the fat oxidation rate(FOR), fat consumption amount(FCA), and carbohydrate consumption rate(CCR). Second, there were statistically significant differences in EPOC(p<0.001), RER(p<0.001), and ECM(p<0.001) in the post-exercise recovery phase, among them, the highest in the IM exercise. In terms of FOR(p=0.002) and FCA(p=0.007), IV and CO exercise were significantly higher than IM exercise, and on the contrary, in terms of CCR(p=0.002) and CCA(p<0.001), IM exercise was higher than IV and CC exercise.CONCLUSIONS In conclusion, considering not only during exercise but also the recovery period after exercise, the intermittent exercise seems to have an advantage in increasing energy consumption while having a shorter exercise time than the other two under the condition of the same exercise amount.
