This study was designed to investigate the effects of 12-weeks Red Ginseng administration on the metabolic responses 14 healthy-male physical activity participants (34.42.86 yrs). The subjects were asigned randomly to two groups, Ginseng Group (N=7) and Placebo Group (N=7) and asked to perform 40 min-submaximal ergometer exercise at fixed load compromised to each subject´s 65% VO_(2max).
Blood samples during submaximal exercise were taken all five times (pre, 10 min, 20 min, 40 min, and post 30 min) and analyzed for various matabolic parameters (Metabolic variables : insulin, glucose, FFA, Lactate).
Statistical techniques for data analysis were applied 2-way repeated ANOVA and t-test.
On the basis of the results analyzed in this study, the conclusion could be drawn as follows ;
1. Energy substrates (plasma glucose, FFA) changes during exercise were not significantly different from placebo group after 12 weeks-ginseng administration.
2. Plasma insulin depression tendency during submaximal exercise in ginseng group was
significantly alleviated after 12 weeks compared to placebo group (p<0.05j.
3. In submaximal exercise, the significant difference in plasma lactate change between
two groups was discovered in pre-40 min time interval from t-test (p<0.05).
This result suggests that ginseng may more contribute to the alleviation of metabolic acidosis in submaximal exercise and the alleviative effect may be achieved by the increment of feul storage in muscle and liver through the improvement of insulin secretion ability.
