Effect of downhill walking on next-day muscle damage and glucose metabolism in healthy young subjects.

This study aimed to investigate the effect of downhill walking on muscle damage and glucose metabolism in healthy subjects. All ten healthy young men and women (age, 24.0 ± 1.

Glutathione supplementation suppresses muscle fatigue induced by prolonged exercise via improved aerobic metabolism.

Backgrounds: Glutathione is an endogenous redox couple in animal cells and plays important roles in antioxidant defense and detoxification, although it is unknown if oral glutathione supplementation affects exercise-induced physiological changes. The present study investigated the effect of glutathione intake on exercise-induced muscle metabolism and fatigue in mice and humans.

Methods: ICR mice were divided into 4 groups: sedentary control, sedentary supplemented with glutathione (2.
