Duration of exercise as a key determinant of improvement in insulin sensitivity in type 2 diabetes patients.
Exercise duration and intensity are important parameters in exercise prescription and play a major role in improving insulin sensitivity ( including transient and persistent improvement effects following cessation of training ) in patients with type 2 diabetes mellitus ( T2DM ) . However , whether duration or intensity of exercise is the more important factor has yet to be established . Therefore , we aim ed to determine whether exercise prescriptions differing in duration and intensity differ in their ability to aid T2DM patients to retain insulin sensitivity following the conclusion of a period of training . Sedentary T2DM patients ( age 51.2 ± 1.3 years ) were assigned to either a low-intensity ( 50 % VO(2peak ) , n = 27 ) or a high-intensity exercise group ( 75 % VO(2peak ) , n = 28 ) , and followed a 12-week exercise program of 5 sessions/week and 240 kcal/session . Insulin sensitivity ( oral glucose tolerance test , ISI ) was measured when subjects were sedentary and at 16 - 24 h and 15 days after the final training bout . The low-intensity group spent more training time to training per exercise session than the high-intensity group ( 56.1 ± 3.0 min/session vs. 34.3 ± 2.4 min/session ) ( P < 0.01 ) , but the total amount of energy expended was the same . ISI was increased in both groups 16 - 24 h after the final training session , but only the low-intensity group still had elevated ISI 15 days after the cessation of training . These findings suggest that in T2DM patients , the persistent training-induced improvements in insulin sensitivity may be more dependent on exercise duration than exercise intensity in regimens with the same level of energy expenditure
