Oxidative Stress and Antioxidant Supplementation of Horses During Endurance Exercise
To compare effects of a dietary supplement containing vitamin E alone or vitamin E plus vitamin C on antioxidant status, oxidative stress and membrane leakage during endurance exercise. A nutritional pre-competition survey allowed horses to be paired and randomly assigned to two groups. Three weeks prior to the competition, one group (E) was orally supplemented with 5,000 IU vitamin E/d, the ot...
متن کاملHigh-dose antioxidant vitamin C supplementation does not prevent acute exercise-induced increases in markers of skeletal muscle mitochondrial biogenesis in rats.
High doses of the antioxidant vitamin C prevent the increases in skeletal muscle mitochondrial biogenesis after exercise training. Since exercise training effects rely on the acute stimulus of each exercise bout, we examined whether vitamin C supplementation also attenuates the increases in skeletal muscle metabolic signaling and mitochondrial biogenesis in response to an acute exercise bout. M...
متن کاملAmla Enhances Mitochondrial Spare Respiratory Capacity by Increasing Mitochondrial Biogenesis and Antioxidant Systems in a Murine Skeletal Muscle Cell Line
Amla is one of the most important plants in Indian traditional medicine and has been shown to improve various age-related disorders while decreasing oxidative stress. Mitochondrial dysfunction is a proposed cause of aging through elevated oxidative stress. In this study, we investigated the effects of Amla on mitochondrial function in C2C12 myotubes, a murine skeletal muscle cell model with abu...
متن کاملA 9-wk docosahexaenoic acid-enriched supplementation improves endurance exercise capacity and skeletal muscle mitochondrial function in adult rats.
Decline in skeletal muscle mass and function starts during adulthood. Among the causes, modifications of the mitochondrial function could be of major importance. Polyunsaturated fatty (ω-3) acids have been shown to play a role in intracellular functions. We hypothesize that docosahexaenoic acid (DHA) supplementation could improve muscle mitochondrial function that could contribute to limit the ...
متن کاملOxidative stress, exercise, and antioxidant supplementation.
Cells continuously produce free radicals and reactive oxygen species (ROS) as part of metabolic processes. These free radicals are neutralized by an elaborate antioxidant defense system consisting of enzymes such as catalase, superoxide dismutase, glutathione peroxidase, and numerous non-enzymatic antioxidants, including vitamins A, E and C, glutathione, ubiquinone, and flavonoids. Exercise can...
