The aim of this study is to find out the effect of different intensities of aerobic exercises on selected physiological variables among diabetic patients. Randomly selected 60 (N=60) diabetic patients whose blood glucose levels were more than 140 mmHg and who were undergoing treatment for diabetics in Government General Hospital, Nagercoil were treated as subjects for this study. They were randomly assigned into four groups consisting of 15 in each group. Group I was considered as low intensity aerobic exercises group (LIAE), group II was considered as medium intensity aerobic exercises group (MIAE), group III was considered as high intensity aerobic exercises group (HIAE) and the fourth group served as control group. Pre and post test scores on cardiac risk factors, breath holding time and cardio respiratory endurance were collected and statistically analysed. The results of the study proved that cardiac risk factors selected were beneficially altered by different intensities of aerobic exercises compared to control group and there was no significant difference among treatment groups. It was concluded that aerobic exercises of different intensities can be prescribed for diabetic patients for managing diabetics and the resultant cardiac risks.
