Abstract

OBJECTIVE Given the transient nature of exercise-induced improvements in insulin sensitivity, it has been speculated that daily exercise is preferred to maximize the benefits of exercise for glycemic control. The current study investigates the impact of daily exercise versus exercise performed every other day on glycemic control in type 2 diabetic patients.

RESEARCH DESIGN AND METHODS Thirty type 2 diabetic patients (age 60 ± 1 years, BMI 30.4 ± 0.7 kg/m2, and HbA1c 7.2 ± 0.2%) participated in a randomized crossover experiment. Subjects were studied on three occasions for 3 days under strict dietary standardization but otherwise free-living conditions. Blood glucose homeostasis was assessed by continuous glucose monitoring over 48 h during which subjects performed no exercise (control) or 60 min of cycling exercise (50% maximal workload capacity) distributed either as a single session performed every other day or as 30 min of exercise performed daily.
