A Study on the Effect of Exercise on Pulmonary Function in Type 2 Diabetes patients.

Abstract

Background: This study aimed to investigate the effect of exercise on pulmonary function in patients with type 2 diabetes. A total of 100 type 2 diabetic patients (aged 18 – 65 years) were recruited from Diabetes and Endocrinology Hayatabad Medical Complex Peshawar. All participants underwent a standard six-minute walk test, before and after regular aerobic exercise training twice a day for three months. Lung function tests were carried out before and after exercise program to measure maximum voluntary ventilation (MVV), forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and peak expiratory flow rate (PEFR). Data analysis showed that, after exercise program, statistically significant improvements in pulmonary function tests were observed with increased FVC, FEV1, and PEFR as compared to baseline values. Results of this study suggest that regular aerobic exercise have a beneficial effect on pulmonary functioning in type 2 diabetic patients.

Objectives:  To investigate the effect of exercise on pulmonary functioning in type 2 diabetic patients.

And To compare the pulmonary functions before and after regular exercise sessions in type 2 diabetic patients and To identify the effect of exercise on the maximum voluntary ventilation (MVV), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow rate (PEFR) in type 2 diabetic patients.

Methods

This study was conducted at Diabetes and Endocrinology Hayatabad Medical Complex, Peshawar, Pakistan from may-2018 to may 2019 This study was a randomized controlled trial  One hundred patients with type 2 diabetes, aged 18–65 years, were recruited for this study.Procedure. All participants underwent a standard six-minute walk test before and after 3 months of regular aerobic exercise program twice a day. Pulmonary function tests (PFTs) were performed before and after exercise program to measure the maximum voluntary ventilation (MVV), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow rate (PEFR) Data analysis. Data were analyzed using SPSS 22.0 software. The independent sample t-test was used to compare the parameters between the baseline and post-intervention scenario. A p-value of <0.05 was considered as statistically significant.

Results

The results of this study showed that there were statistically significant improvements in all PFT parameters after regular exercise program. The mean FVC was found to be increased from 2.45 ± 0.45L at baseline to 2.71 ± 0.51L post-intervention (p-value <0.001). Similarly, the mean FEV1 was increased from 2.02 ± 0.38L at baseline to 2.25 ± 0.44L post-intervention (p-value <0.001). Also, the mean PEFR was increased from 5.02 ± 0.86L/sec at baseline to 5.78 ± 0.91L/sec post-intervention (p-value <0.001). Furthermore, the mean MVV was found to be increased from 17.03 ± 2.88L/min at baseline to 19.29 ± 3.33L/min post-intervention (p-value <0.001).

Conclusion

The results of this study indicate that regular aerobic exercise have beneficial effects on pulmonary functioning in type 2 diabetic patients with enhanced pulmonary functions observed in all measured parameters i.e., FVC, FEV1, PEFR and MVV. Therefore, regular aerobic exercise should be recommended in type 2 diabetic patients in order to improve their pulmonary functioning.
