Abstract |
This study was performed to investigate the effect of herb extract ingestion and moderate exercise training on aerobic capacity, anabolic hormone concentration, and immune system in middle aged men (35-47yrs, n = 39). The herb extract made of Garnoderma lucidum, Rosa roxburghii tritt, and Astragalgi Radix were ingested 3 times a day and aerobic exercise training was performed at 50-60% of VO₂max during 12 weeks (60 minutes·day^(-1), 5 days·week^(-1)). All subjects were divided into 4 groups according to exercise training and ingestion. All of subjects performed maximal treadmill exercise test before and every 6 weeks of training. Maximal oxyzen uptake (VO₂max) and aerobic threshold (AT) in training with ingestion group (6 wk, 12 wk) and exercise group (12 wk) was higher than those of control group (p<.05). Anabolic hormone concentrations in training without ingestion group was higher than control after 12 weeks (p<.05). Triglycerides in training with ingestion group (12 wk) was lower than control after 12 weeks (p<.05). Most of immune cell composition in blood were unchanged after 12 weeks. In conclusion, herb extract ingestion can be effective to improve aerobic performance. But it seems that herb extract ingestion itself may not the case to improve anabolic hormone secretion and immune cell composition, wherase exercise training demonstrates a positive effective in anabolic hormone secretion in middle aged men. |
