- Abstract
Swimming enhancement effects of ethanol extract from ripe Rubus coreanus (RCE) fruits were investigated in mice. An Ex-RCE group was orally administered 1 g/kg body weight/day of RCE. An Ex-Control group received distilled water for 28 days. Exhaustive swimming times were significantly ( p<0.05) prolonged in Ex-RCE mice, compared with Ex-Control mice. Ex-RCE mice had lower lactate and higher glucose levels after exhaustive swimming. Plasma non-esterified fatty acid levels in Ex-RCE mice were significantly ( p<0.05) increased during swimming, compared with Ex-Control. Lower plasma triglyceride levels were shown in Ex-RCE mice after swimming. Ex-RCE mice exhibited higher muscle glycogen and lower malondialdehyde levels, compared with Ex-Control mice. RCE is a useful agent for enhancement of the swimming capacity and amelioration of physical fatigue via a decrease in lactate accumulation, and supply of energy sources via glycogen sparing and facilitation of fat use, and reduction of lipid peroxidation levels through swimming.
