Abstract

OBJECTIVES : Ginseng Research Group in Korea Food Research Institute developed Saeng Mac San (KFRI-2)and Je Ho Tang (KFRI-3) with their sensory factors more acceptable. And we examined their effects on the short-term recovery capacity for cycling exercise (EX) maintained to all-out. METHODS : Seven healthy young subjects (aged 24.0 ± 2.1 yr) were volunteered at this double blind test. Each of KFRI-2,3, a commercial sport beverage and control (CON) was offered randomly on a series of EX protocol including 65% VO2max-90min EX (D-ride), 1h-recovery and 85% VO2max EX to all-out (P-ride) under the control of their heart rate (HR) and rating perception of exertion (RPE). Blood samples were collected before D-ride, 30, 60 and 90min in D-ride, 30 and 60min in the recovery period and each 10min in P-ride. Plasma analysis items were glucose, insulin, cortisol (CORT), testosterone (TEST), free fatty acid (FFA), Na+, Cl- and K+. The collected data (Means±SE) were analysed by two-way ANOVA and statistically significant differences between treatments (p〈0.05) by LSD.; the significant level in FFA, Na+, Cl- and K+ was p〈0.01. RESULTS : At 30min during recovery, plasma glucose level in KFRI-3 was significantly higher than CON, and also insulin in KFRI-3 was than CON and KFRI-2. FFA in KFRI-3 was significantly lower than CON during recovery. Na+ in KFRI-3 significantly higher than CON at 90min in D-ride, and also KFRI-2 was at 60min during recovery. However CORT, TEST, Cl- and K+ in treated beverages were not significant. KFRI-2,3 elevated the time for P-ride more than CON did. CONCLUSIONS : KFRI-2,3 elevated the time for P-ride about 12% more than CON did. It is based on rapid recovery of plasma glucose level and inhibition of lipolysis during recovery.
