Glycemic control and the role of exercise in obese type-2 diabetics

ABSTRACT

To assess the role of exercise on serum levels of glucose, insulin and triglycerides in type-2 diabetics and to assess the therapeutic value of exercise in the management of type-2 diabetes mellitus in obese subjects. A total number of thirty sedentary subjects were included in this study. Half of them were obese, normal, healthy subjects [Group-I] half [15] were obese, type-2 diabetics [Group-II]. Both the groups were having non-significant differences regarding age, sex and Body mass index, although both groups have a BMI of more than 30. Before the start of the exercise period fasting blood samples were collected to establish the baseline parameters in each case. The subjects underwent a session of 30 minutes of moderate intensity exercise daily for ten days. Another fasting blood sample was drawn from each subject after 10 days. Parameters in pre and post exercise period were compared. Serum glucose levels decrease significantly [p<0.05] in both the obese control group as well as the obese diabetic group but the decrease was more marked in obese diabetic group. Serum insulin levels were non-significantly [p>0.05] decreased in both groups. Serum triglycerides were also decreased significantly [p<0.05] in both the groups. Exercise has beneficial effects to decrease the serum levels of glucose and triglycerides. So, the exercise has a very important role in the management of type-2 diabetes mellitus in obese patients
