Abstract

The purpose of this research was to examine the effect of garlic intake and aerobic exercise on blood lipids, exercise performance, and on antioxidant function after muscle damage exercise in male university students. 28 subjects were divided into control(C, n=7), aerobic exercise(E, n=7), garlic intake(G, n=7), and garlic intake+aerobic exercise(GE, n=7 ) groups. Aerobic exercise program was carried out under the condition of 50～60% of HRmax, 5 days/wk for 12 wks. Garlic intake group was supplemented with commercial garlic extract(about 27 cloves of garlic a day for 12wks). blood lipids, O2max and antioxidant function(MDA, SOD, CAT, GPx) of all subjects were measured at the point of 0wk and 12th wk. Besides, as soon as 12wks have been passed, muscle damage exercise(bench stepping with 15 step/min) was performed. Then only antioxidant function of all subjects were measured at the 1st, 12th, and 24th hr of the recovery phase. All data were expressed as mean and standard deviation by using SPSS program, and two-way ANOVA with repeated measure was performed to test interaction of group and period. Significance was set at the p<0.05. There was no significant difference in TG within and between groups. TC and LDL-C was significantly decreased within GE group, and GE group was shown that there was a significant difference of TC and LDL-C levels, compared with C group. HDL-C was significantly increased within GE group, and GE group was shown that there was a significant difference of HDL-C levels, compared with C group. the level of MDA was shown that there was no significant difference within and between groups following 12 wks, and also in the recovery phase of muscle damage exercise. However, SOD was significantly increased within GE group and GE group was shown that there was a significant difference of SOD, compared with C group following 12 wks. And GE group was shown that there was a significant difference of SOD at the 1st, 12th hr of the recovery phase of muscle damage exercise after 12wks, compared with C group. CAT was significantly increased within GE group and G group following 12 wks, and we examined a significant difference in GE group at the point of 24th hr of the recovery phase of muscle damage exercise after 12 wks, compared with C group. The increase of GPx was observed in GE group following 12 wks, and G group was shown that there was a significant difference of GPx at the 24th hr of the recovery phase of muscle damage exercise after 12 wks, compared with C group. The increase of O2max was observed within all groups, but not significant difference of O2max between groups. All-out time was not shown that there was any significant difference between groups as well as within groups after garlic intake and regular aerobic exercise. In summary, when considering the above results, we conclude that combined treatment of garlic intake and aerobic exercise can decrease blood lipids and improve antioxidant function following 12wks, and it can ameliorate antioxidant function for recovery phase after muscle damage exercise.
