Cells continuously produce free radicals and reactive oxygen species (ROS) as part of
metabolic processes. These free radicals are neutralized by an elaborate antioxidant …

The chronic exposure to regular exercise training seems to improve antioxidant defense
systems. However, the intense physical training imposed on elite athletes may lead to …

The aim of this work was to demonstrate the occurrence of oxidative stress during
exhaustive exercise and to determine the antioxidant response. Eight voluntary male …

The purpose of this study was to determine the changes of both oxidant and antioxidant
levels with exercise training in obese middle-aged women. The association between …

Hydrogen peroxide (H2O2) could induce oxidative damage at long distance from its
generation site and it is also an important signalling molecule that induces some genes …

Antioxidant enzymes (superoxide dismutases, catalase and glutathione peroxidase) are
components of an organism's mechanisms for combating oxidative stress which is …

The aim of this study was to investigate whether endurance training reduces exercise-
induced oxidative stress in erythrocytes. Male rats (n= 54) were divided into trained (n= 28) …

OBJECTIVES: Oxidative stress is implicated in the pathophysiology of many cardiovascular
diseases. Plasma glutathione peroxidase (pl• GPx, GPx3) is an antioxidant enzyme found in …

We determined the effects of dietary vitamin C supplementation on erythrocyte antioxidant
enzymes and on plasma antioxidants during athletic competition and short-term recovery …

Background: Heavy exercise induces marked immunodepression that is multifactorial in
origin. Nutrition can modulate normal immune function. Objective: To assess the efficacy of …
