Effects of supplementation of high pressured red ginseng and ginseng berry on the duration of running time to exhaustion and the body lipid profiles in SD rats

5주간의 초고압 홍삼섭취가 흰쥐의 운동지속시간 및 체내 지질성분에 미치는 영향

This study evaluated the effects of high pressured red ginseng(HRG) and ginseng berry(GB) supplementation on lipid profiles and run to exercise time in SD rats. Five weeks-old male rats were randomly assigned into six groups, ie. control group(AC: n = 8), exercise group(AE: n = 7), general extracted red ginseng group(C: n = 8), HRG group(high density D: n = 8, low density E: n = 7), and HRG + GB group(F: n = 7). The AC and AE groups had a supplementation of AIN-93G, and AE group performed 40 min treadmill exercise five times per week for five weeks. E, C, D, and F groups had a supplementation composed of general extracted red ginseng(GRG), HRG(250 mpk and 500 mpk), and HRG(250 mpk) + GB(167 mpk) in the AIN-93G. Main results of the study were as follow 1) the duration of running time to exhaustion was higher in exercise group compared to other groups. HRG had no effect on run to exhaustion time, but, GRG and HRG + GB showed longer run time than control groups. 2) Blood TC, TG, HDL-C and liver TG showed no difference between groups, but, liver TC showed lower level in the HRG groups than other groups. It was concluded that the 5 weeks of supplementation of HRG extract would have positive effects on liver cholesterol, and GRG and HRG + GB have a positive effect on exercise performance tested run to exhaustion time, but, we can not find a positive effect of supplementation of HRG on exercise performance.
