[Effect of Ciwujia (Radix Acanthopanacis senticosus) preparation on exercise performance under constant endurance load for elderly].
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.
