Korean Wild Ginseng (KWG) has been known to have efficacy not only in physical stamina but also in anti-oxidative and anti-inflammatory properties. However, its effect on performance recovery by acute strenuous exercise is not well known.

PURPOSE: To investigate the effects of KWG Drink on performance recovery from acute strenuous exercise (ASE).

METHODS: This study was conducted in double-blind, counterbalanced, placebo-controlled design with 14 days washout periods. Ten healthy male volunteers (27.1 ± 4.33 years old) were randomly assigned to one of two parallel trials. KWG (2g of KWG; 16.8 mg of ginsenosides/package) or placebo supplementation were consumed right after ASE and following 4 days (2 packs/day). The ASE program consisted of downhill running and jumping exercise. Subjects performed downhill running (-10 %) for 20 minutes at 60 % of VO2 max. After downhill running, subjects performed jumping exercise that consisted of five sets of 20 maximal drop jumps from height of 60 cm with a 10 seconds interval between jumps and 2 minutes rest between each set. Peak and mean power, isometric muscle strength, electromyography activity, cognitive function, cortisol, interleukin-6 (Il-6), myoglobin, total antioxidant capacity (TAC), and muscle soreness were assessed at each time points: baseline, 2, 48, and 96 hours after ASE. A series of 2 x 4 repeated measures ANOVA, and MANOVA were used to determine differences according to the supplementation.

RESULTS: There were no statistical differences in performance (F= 0.368, p= .970), cognitive function (F= 0.366, p= .983), blood variables (cortisol: F= 0.598, p= .584; IL-6: F= 1.662, p= .206, myoglobin: F= 0.574, p= .544, TAC: F= 1.508, p= .241), and muscle soreness (F= 0.760, p= .462) according to the supplementation.

CONCLUSION: Supplementation of KWG extract has no efficacy for performance recovery from acute strenuous exercise in healthy male subjects. Dosage and short duration of KWG application may produce non-significance results. Further studies are needed to investigate the different dosage and duration of KWG supplementation on performance recovery.
