Radix Acanthopanacis Senticosi (RAS) has been used to increasing energy and vitality for over 2,000 years in Chinese medicine. This study examined the effects of oral RAS supplementation on antifatigue function for 8 weeks. Eighteen healthy male and female college students successfully completed the trial, after randomly receiving in a double-blind design an oral dose of 600 mg RAS or placebo (P). Subjects did the cycling exhaustion exercise tests, which at baseline and after 8 weeks of daily supplementation. Blood parameters were collected before, between and after each exhaustion exercise trial. Statistical analyses showed significant differences (p<0.05) between the RAS and P groups at the endurance exercise time increased 30% and the HRmax increased 4%. After the exhaustion exercise, blood lactic acid decreased 18% and 20% increased in blood free fatty acid. We conclude that oral Radix Acanthopanacis Senticosi supplementation 600 mg per day for 8 weeks may enhance aerobic capacity, increase endurance exercise time, and has anti-fatigue effects in human. We recommend Radix Acanthopanacis Senticosi as an effective nutritional ergogenic aids for the endurance athletes.
