Abstract
The purpose of the present study was to examine effect of 12 week regular aerobic exercise on ST-segment and QTc interval in middle age type 2 diabetes mellitus (T2DM) patients. The subjects consist of 13 type 2 diabetes mellitus (T2DM) patients in middle age men and all of them had no other complications. Subjects participated in aerobic exercise training for 12 weeks. They started to exercise for $20{\sim}60$ min at $60{\sim}80%$ of $HR_{max}$, (exercise intensity has been increased gradually) per day, $3{\sim}5$ times a week. The results were compared before and after. Weight and BMI, % body fat, fasting glucose, HOMA-IR, $_{peak}DBP$ were significantly decreased and $_{peak}HR$, $_{peak}VO_2$, exercisre time were significantly increased after 12 week aerobic exercise. Also, QTc interval and ST-segment were significantly decreased during at rest, peak exercise after 12 week aerobic exercise. Conclusionally, 12 week aerobic exercise may be improvement in decreased cardiovascular mortality factors (ST-segment) and abnormal autonomic dysfunction (QTc interval) and potentially increased exercise capacity.
