Rosa rugosa Aqueous Extract Alleviates Endurance Exercise-Induced Stress.

This study was performed to investigate the effect of water extract from Rosa rugosa (RRW) on endurance exercise-induced stress in mice. The mice were orally administered with distilled water or RRW, respectively. The endurance capacity was evaluated by exhaustive swimming using an adjustable-current water pool. Mice administered RRW swam longer before becoming exhausted. Also, RRW administration resulted in less lipid peroxidation, lower muscular antioxidant enzyme activities, and lower cortisol level. The results suggest that RRW can prevent exercise-induced stress by decreasing oxidative stress levels.
