The effect of daily physical activity on oxidative stress is still an unknown issue, especially in middle-aged and elderly individuals. In this study, we examined the relationships of oxidative stress and antioxidant capacity with daily physical activity, taking into consideration the dietary antioxidant vitamin intake (vitamin B9, C and E) of middle-aged and elderly people (66.0±7.0 years, n= 21; 10 males and 11 females, including 5 male trained runners). Daily physical activity was measured using both a calorie counter and a questionnaire over a period of two weeks. The plasma concentration of thiobarbituric acid reactive substance ([TBARS]) and both oxidized and reduced glutathione concentrations ([GSSG] and [GSH]) in whole blood were determined in blood samples obtained at rest and immediately after two periods of acute exercise : maximal cycle ergometric exercise and steady state cycle exercise at 80% of ventilatory threshold (VT) for 30 minutes. At a given statistically controlled dietary antioxidant vitamin intake level (vitamin B2, C and E), the amount of daily physical activity was associated with neither [TBARS], [GSH] and the ratio of [GSSG] / [GSH] at rest, nor changes in levels of these substances after both exercise tests. These data suggest that the amount of daily physical activity may have little influence on oxidative stress or antioxidant capacity at rest and after acute cycle ergometric exercise. Further investigation would be necessary to clarify how much volume or intensity of physical activity induces increased oxidative stress, from the aspect of habitual physical training and nutrition.
