Abstract EN
Antioxidant defences are essential for cellular redox regulation.
Since free-radical production may be enhanced by physical activity, herein, we evaluated the effect of acute exercise on total antioxidant status (TAS) and the plasma activities of catalase, glutathione reductase, glutathione peroxidase, and superoxide dismutase and its possible relation to oxidative stress resulting from exercise.
Healthy untrained male subjects (n=34) performed three cycloergometric tests, including maximal and submaximal episodes.
Venous blood samples were collected before and immediately after each different exercise.
TAS and enzyme activities were assessed by spectrophotometry.
An increase of the antioxidant enzyme activities in plasma was detected after both maximal and submaximal exercise periods.
Moreover, under our experimental conditions, exercise also led to an augmentation of TAS levels.
These findings are consistent with the idea that acute exercise may play a beneficial role because of its ability to increase antioxidant defense mechanisms through a redox sensitive pathway.
