<abstract xmlns="http://www.w3.org/1999/xhtml"><p>The aim of the present study was to assess the effects of two metabolically different exercise programs on the redox state of women who were physically inactive before the beginning of the study.

At the beginning and end of the study, body composition analysis and venous blood sampling were performed. The levels of superoxide anion radical, hydrogen peroxide, nitric oxide and lipid peroxidation were measured in plasma, and the levels of reduced glutathione and the activity of superoxide dismutase and catalase were measured in erythrocytes. Only the Tae Bo program induced changes (positive) in body composition, whereas both exercise programs induced slight oxidative stress in exercisers. In the Tae Bo group, the levels of hydrogen peroxide were significantly increased, whereas the levels of reduced glutathione were decreased after three months of training.
