The Immediate Effects of Aerobic Exercise with and Without External Loads on Blood Glucose, Cardiovascular, Respiratory, and Body Temperature Indices in Type II Diabetic Patients


Background: The long-term effects of aerobic exercise on the cardiorespiratory system have been studied extensively. This study aimed to evaluate the effects of aerobic exercise with and without external loads on blood glucose, cardiovascular, respiratory, and body temperature indices in patients with type II diabetes.

Methods: The present randomized control trial recruited participants from the Diabetes Center of Hamadan University through advertisement. Thirty individuals were selected and divided into an aerobic exercise group and a weighted vest group via block randomization. The intervention protocol included aerobic exercise on the treadmill (0 slopes) with an intensity of 50% to 70% of the maximum heart rate. The exercise program for the weighted vest group was identical to that of the aerobic group, except that the subjects wore a weighted vest.

Results: The mean age of the study population was 46.77±5.11 years in the aerobic group and 48±5.95 years in the weighted vest group. After the intervention, blood glucose in the aerobic group (167.07±72.48 mg/dL; P<0.001) and the weighted vest group (167.75±61.53 mg/dL; P<0.001) was decreased. Additionally, resting heart rate (aerobic: 96.83±11.86 bpm and vest: 94.92±13.65 bpm) and body temperature (aerobic: 36.20±0.83 ℃ and vest: 35.48±0.46 ℃) were increased (P<0.001). Decreased systolic (aerobic: 117.92±19.27 mmHg and vest: 120.91±12.04 mmHg) and diastolic (aerobic: 77.38±7.54 mmHg and vest: 82.5±11.32 mmHg) blood pressure and increased respiration rate (aerobic: 23.07±5.45 breath/min and vest: 22±3.19 breath/min) were seen in both groups but were not statistically significant.

Conclusion: One aerobic exercise session with and without external loads reduced blood glucose levels and systolic and diastolic blood pressure in our 2 study groups.
