The purpose of this study was to investigate the effects of complex ergogenic aid supplementation on endurance performance, energy substrate utilization (glucose, FFA) and blood fatigue factors (ammonia, lactate, phosphorous, pH, 5-HT) in endurance exercise. Subjects (male=10) took in complex ergogenic aid (180 ml/day) for 4 weeks and were tested after pre-test. Endurance performance times increased after supplementation compared to before supplementation. However, there was no additional accumulation of the fatigue materials. Thus the complex ergogenic aid supplementation caused the delay of the fatigue material accumulation during endurance exercise.

Objective: Physical inactivity contributes to mortality rates and is now the fourth most frequent cause of death worldwide. Red ginseng is a medicinal herb that is often used as an ergogenic aid. In this study, red ginseng was administered to rats to test whether it affected their ability to exercise. Methods: Forty-five rats were randomly distributed and divided into five groups: normal (N, n=5), control (C, n=10), the group to which only red ginseng was administered (H, n=10), the group to which only amino acid complex was administered (A, n=10), and the group to which both red ginseng and amino acid complex were administered (HA, n=10). Once a day for three weeks, 333.3 mg/kg body weight per day (b.w./day) of red ginseng and 750 mg/kg b.w./day of amino acid preparation were administered to rats. After three weeks, body weight, swimming time, and the weight of the anterior tibialis muscle of rat were measured. Blood was taken for analysis using the cardiac puncture method. Results: The swimming time of group H (921.3±199.26 sec) showed significant improvement compared to that of group C (798.48±156.37 sec) (p<0.05). Conclusion: Red ginseng has improved swimming time in rat and can be used as an effective ergogenic aid.
