Recently, HIIT has been recommended by the American diabetes association for type 2 diabetes. The high-volume HIIT has been studied extensively in patients with type 2 diabetes, however, little is known about the effectiveness of low-volume HIIT regarding target glycemic or lipid control in these patients. Therefore, the purpose of this study is to compare between two subtypes of HIIT (i.e. the low-volume HIIT versus the high-volume HIIT) with respect to exercise-induced changes in blood glucose, lipid profile and anthropometry in patients with type 2 diabetes mellitus. Statement of the Problem Is there any difference between the effect of high-volume and the low-volume high intensity interval training on glycemic and lipids control in type 2 diabetes? Purpose of the study: To assess the effect of the high-volume versus the low-volume high intensity interval training on glycemic and blood lipids control in type 2 diabetes. Null Hypothesis: There will be no difference between the effect of the high-volume versus the low-volume high intensity interval training on glycemic and blood lipids control in type 2 diabetes.

patients will undergo a warm up at 65%-70% of HRpeak for 5 minutes, and then they will walk on a treadmill for 4 intervals of 4 min each at an intensity corresponding to 85%-90% of HRpeak with 3 min active recovery interval interval in between at 65%-75% of HRpeak. Finally, a 3-min cool-down period will be permitted. The speed and the inclination of the treadmill will be adjusted between intervals to ensure that all patients are exercising at the desired target heart rate monitored by Pulse Oximeter.
Each session will start with a 5-minute warm up at 65-70% of peak HR. Then they will walk on a treadmill for 4 intervals of 2 min each at an intensity corresponding to 85%-90% of HRpeak with three intervals of active recovery in between for 2 min at 65%-75% of HRpeak. Finally, a 3-min cool-down period will be permitted.
