| 摘 要： | 以１３名５０～５７岁志愿者为试验对象，研究了刺五加制剂对人体运动能力的影响。结果表明服用刺五加制剂后，在４５０ｋｇ．ｍ／ｍｉｎ（７５Ｗ）持速恒定功率负荷运动时呼吸商由０．９６下降至０．８８，使运动时脂肪供能增加２７．２％；心率下降８．７％，每博摄氧量增加１６．１８％。结果均提示刺五加制剂能提高人体摄氧能力，节省肌糖元，从而发挥抗疲劳作用

| Abstract: | The effect of Ciwujia (Radix Acanthopanacis senticosus) preparation on human exercise performance was investigated by using 13 healthy volunteers aged 50-57. Under constant endurance load with 450 kg.m/min (75 W), the respiratory quotient after taking Ciwujia preparation was reduced to 0.88 from 0.96, which implied that the utilization of lipid increased with 27.2% as energy fuel during exercise. Meanwhile, the heart rate was reduced with 8.7%, and O2 uptake per heart beat increased with 16.18%. All results indicated that the Ciwujia preparation could increase O2 uptake, spare the glycogen in muscle and improve the exercise endurance and work performance in human subjects. |
