OBJECTIVES This study was to investigate the effects of aerobic exercise at different intensities on body composition and the derivatives of reactive oxygen metabolites & biological antioxidant potential. METHODS The recruited subjects of thirty young men without any medical problems were divided into LEAI(light-exercise aerobic intensity, n=10), MEAI(moderate-exercise aerobic intensity, n=10), and VEAI(vigorous-exercise aerobic intensity, n=10). The variables were measured to the body compositions (%body fat, BMI & WHR) and the derivatives of reactive oxygen metabolites & biological antioxidant potential) on pre-and post-exercise protocol programs for 8 weeks. The collected blood samples from a fingertip were analyzed with FRAS evolve, H & D co., Italy. Statistical analysis used the two-way repeatedmeasures ANOVA and Tukey’s test for post-hoc analysis and test of homogeneity with Levene’s F value. RESULTS The results are as follows; In body compositions, %body fat was shown a significant difference between pre-and post-exercise in the VIAE group and a significant difference between LIAE & VIEA and MIEA group in post-exercise. WHR(waist to hip ratio) was shown a significant difference between LIAE & VIEA and MIEA group in post-exercise. The oxidative stress, d-ROM(derivatives of Reactive Oxygen Metabolites) was not shown a difference significantly, and BAP(Biological Antioxidant Potential) significant difference between pre-and post-exercise in LIEA & VIEA groups. CONCLUSIONS In conclusion, it increased oxidative stress parameters, the derivatives of Reactive Oxygen Metabolites, and Biological Antioxidant Potential in each group after 8 weeks of exercise. The antioxidant defense system was revealed to ensure biological safety in regular exercise situations.
