    Objectives. Our aim was to determine the effect of chronic regular exercise on ischemia-modified albumin (IMA) levels and oxidative stress in type 2 diabetes mellitus (DM). Design and methods. Sixty patients with type 2 DM were randomly divided into two groups as exercise (17 M, 13 F) and non-exercise (12 M, 18 F) groups, each consisting of 30 patients. The exercise group underwent a 3-month aerobic regular exercise consisting of moderate-intensity power walking. The non-exercise subjects remained sedentary throughout the study period. Serum total antioxidant status (TAS), total oxidant status (TOS), and IMA levels of the groups were determined at baseline and 3 months later. Results. There was no significant change in TOS and IMA levels of exercise group but TAS levels were significantly increased (p < 0.05). Also, postexercise systolic (p < 0.001) and diastolic (p < 0.05) blood pressures of the exercise group were significantly lower than the baseline values. In addition, there was no significant change in TAS and TOS levels of the non-exercise group; however, IMA levels were significantly increased (p < 0.01). Conclusion. We have shown, for the first time, that exercise prevents increase in IMA levels in type 2 DM which might have resulted from increased levels of TAS and reduces the risk of ischemia in these patients. These findings show that chronic exercise is beneficial in the prevention of oxidative stress in patients with type 2 DM as documented by decreased IMA levels.
