27 1(2006 3) J Korean Oriental Med 2006;27(1):36-46 Effect of Oral Sport Beverages with Medicinal Herbs Added on Short-term Recovery from Exercise-induced Fatigue Hyun-Jong Na, Kyu-Lark Lee, Ho-Youl Kang 1) Graduate School, Kyungpook National University Department of Physical Education, Kyungpook National University 1) 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 (MeansSE) were analysed by two-way ANOVA and statistically significant differences between treatments (p0.05) by LSD.; the significant level in FFA, Na +, Cl- and K + was p0.01. 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.
