Dietary antioxidants and exercise
TLDR
There is limited evidence that dietary supplementation with antioxidants will improve human performance, and it is currently unclear whether regular vigorous exercise increases the need for dietary intake of antioxidants.Abstract:
Muscular exercise promotes the production of radicals and other reactive oxygen species in the working muscle. Growing evidence indicates that reactive oxygen species are responsible for exercise-i...read more

Exercise-induced oxidative stress: cellular mechanisms and impact on muscle force production
TL;DR: O Ongoing research continues to probe the mechanisms by which oxidants influence skeletal muscle contractile properties and to explore interventions capable of protecting muscle from oxidant-mediated dysfunction.

Reactive oxygen species: Impact on skeletal muscle
TL;DR: Ongoing research continues to explore the redox-sensitive targets in muscle that are responsible for both redox regulation of muscle adaptation and oxidant-mediated muscle fatigue.
Journal ArticleDOI
Antioxidant supplementation during exercise training: beneficial or detrimental?
TL;DR: The main findings are that, in certain situations, loading the cell with high doses of antioxidants leads to a blunting of the positive effects of exercise training and interferes with important ROS-mediated physiological processes, such as vasodilation and insulin signalling.

Direct observation of a free radical interaction between vitamin E and vitamin C
TL;DR: Direct observation of the interaction between vitamin E and vitamin C and the resulting vitamin E radical then reacting with vitamin C to regenerate vitamin E is reported, which is felt to be an important feature in the maintenance of vitamin E levels in tissues.
