Isoprostanes are a complex family of compounds produced from arachidonic acid via a free-
radical-catalyzed mechanism. They can be quantified as reliable markers of lipid …

Reactive oxygen species (ROS) play an important role as mediators of skeletal muscle
damage and inflammation after strenuous exercise. These ROS arise largely from increases …

Scientific advances in this field have not only given us a better understanding of what is an
optimal diet, but has allowed food and nutraceutical companies to market products with …

Strenuous exercise leads to an increase in metabolic rate, increased production of reactive
oxygen species, and compromised antioxidant defense systems. To study the effects of …

During exercise a number of potential sources exist for the production of reactive oxygen
species such as superoxide anions, hydrogen peroxide and hydroxyl radicals. Oxidative …

Muscle damage resulting from eccentric exercise provides a useful model of oxyradical-
induced injury and can be used to examine age-related responses to oxidative stress …

Isoprostanes are produced during peroxidation of membrane lipids by free radicals and
reactive oxygen species. Initially, they were recognized as being valuable markers of …

Flavan-3-ols are potent antioxidants in vitro, but convincing evidence for antioxidant action
in vivo is lacking. We examined whether an oxidative stress-mediated increase in plasma F2 …

Exercise has been shown to increase the production of reactive oxygen species to a point
that can exceed antioxidant defenses to cause oxidative stress. Dietary intake of …

This study tested the development of oxidative stress and the effects of antioxidant
supplementation in an 80-km ride. A precompetition survey revealed that no competitor …
