Abstract

Cardiac autonomic neuropathy (CAN) is a common diabetes complication. Injury of the autonomic nerves distributed in the heart and blood vessels in patients with diabetes may result in cardiac autonomic neuropathy and increase their risk of death. Therefore, CAN prevention is of considerable importance for these patients. The purpose of this study was to determine the effect of 12 weeks aerobic, strength and concurrent training on heart rate variability (HRV) and some specification of heart structural in Type-2 diabetic neuropathy men. In this quasi-experimental clinical trial, 45 men with diabetes were randomly divided into four groups: aerobic training (n=11), Strength training (n=11), concurrent training (n=11) and control group (n=12). Three groups receiving three weekly sessions for 12 weeks. Heart rate variability in the patients was measured by using a Holter monitor for 20 minutes and heart structural features by echocardiography prior to and following the three-month exercise period. The repeated measures ANOVA (2 ͯ 2), paired samples T-test, one-way ANOVA, and Tukey’s post-hoc test were used to analyze the data. The results of intra-group showed that in three exercise training group, there were significant difference between pre and posttest in the SDNN and rMSSD parameters among the time domain indices, and changes in the HF Power and LF/HF ratio parameters among the frequency-domain indices (P < 0.05). The results inter-group indicated that, changes in all time domain and frequency-domain values (except for the LF Power parameter) in the exercise groups were significantly different from those in the control group (P < 0.05). Intra-group changes revealed that changes in posterior wall thickness in Systole (PWTS) in aerobic training and changes in posterior wall thickness in Diastole (PWTD) in strength training were significant, whereas changes in inter ventricular septal thickness in Systole (IVSTS) and changes in inter ventricular septal thickness in Diastole (IVSTD) were not significant difference in any of the exercise groups. Inter- group changes in heart structural features also showed that the type of exercise (aerobic, strength and concurrent training) no significantly effects on heart structural features (PWTS, PWTD, IVSTS and IVSTD) in men diabetic neuropathy. It seems that three types of aerobic, strength, and concurrent training improved the function of the cardiac autonomic nervous system and, hence, increased heart rate variability in patients with diabetes who were afflicted with peripheral neuropathy. Moreover, as for the effects of the exercises on the heart structural features, we can say that aerobic and strength training increased left ventricular posterior wall thickness and, therefore, improved heart function.
