Abstract:

Background and aim: Lack of physical activity increases the risk of cardiovascular disease, diabetes, pulmonary function and sleep quality, but with regular physical activity, may reduce many of these risk factors. The aim of this study was to find the effects of aerobic training on serum levels of nitric oxide, pulmonary function parameters and quality of sleep in women with type 2 diabetes.

Methods: In the present quasi-experimental study, 20 type 2diabetic women were selected and randomly assigned into two exercise (n = 12) and control (n = 8) groups. Aerobic training program was performed for six weeks (4 times a week, with 50% to 80% heart rate reserve) who receive the time and intensity of exercise (50 to 80 HRR) was added. Main aerobic exercises presented in the form of 6 chain, each chain includes 32 motion. FVC, FEV1 Indices and nitric oxide levels were measured before and after the intervention and Pittsburgh Sleep Quality Index questionnaires were used to assess sleep quality. Statistical analysis were analyzed using t-test, analysis of covariance and correlation coefficient.

Results: Six weeks of aerobic exercise indicated a significant reduction in sleep quality scores and but a significant increase in the concentration of nitric oxide and lung volumes (FVC and FEV1) compared to the control group (p≤ 0.05), but no significant relationship between lung volumes and a score of sleep quality was observed.

Conclusion: It seems that aerobic exercise training can have a considerable impact on serum nitric oxide pulmonary functions and thereby improve the sleep quality in patients with type 2 diabetes.
