Background and Aim: This study aimed to investigate the effect of exercise timing on elevated postprandial glucose and after brief interval exercises in women with obesity.
Methods & Materials: Ten women with obesity (Mean±SD age = 40.41±3.97 years; weight = 86.66±7.26 kg; and BMI = 33.22±2.20 kg/m2) participated in a crossover design exercise intervention: 1) postprandial aerobic exercise, 2) pre-prandial aerobic exercise, 3) brief periodic exercise, and 4) control. Pre- and postprandial exercise included 30 min of moderate-intensity walking on the treadmill before and after each main meal (1 minute of exercise -30 seconds rest). The brief periodic exercise had three one-minute reps of activity every 30 min for 20 times during the day. Twelve-hour continuous glucose monitoring and two-hour postprandial glucose levels were calculated to examine changes in blood glucose levels.
Ethical Considerations: This study was approved by the institutional review board of the University of Isfahan (Ethics Code: IR.UI.REC.1397.119) and conducted in agreement with the ethical principles for biomedical research involving human subjects outlined in the declaration of Helsinki.
Results: The findings of this study suggested that brief periodic exercise resulted in a significant decrease in continuous glucose monitoring levels and postprandial glucose compared to the control group as well as pre-prandial exercise (P˂0.05). However, pre- and postprandial exercise did not result in significant changes in continuous glucose monitoring (P˃0.05). In addition, postprandial exercise led to a significant decrease in postprandial glucose compared to the control group (P˂0.05).
Conclusion: It seems that brief periodic exercise can have more beneficial effects on postprandial glucose levels, probably due to improved glucose metabolism in skeletal muscle.
