Abstract

The fatigue-alleviating effects on mice of Rubus coreanus were investigated by using an adjustable-current water pool. The mice were exhaustively exercised for 2 consecutive days, and those administered with the 80% ethanol extract (RCE) of R. coreanus displayed a lower reduction (20%) in swimming time on day 2 than the control group (41% reduction). RCE significantly prevented the depletion of hepatic antioxidants during exercise-induced fatigue. These results suggest that RCE alleviated fatigue by elevating the antioxidative potential.
