Background & Aims: Dysfunction in the autonomic nervous system causes secondary complications in the elderly with type 2 diabetes. The aim of the present study was to survey the effect of walking exercise on insulin resistance, lipid profile, and heart rate variability in the elderly with type 2 diabetes.
Materials & Methods: The present research method was semi-experimental with a pre-test-post-test design. The statistical population of the present study was made up of all type 2 diabetic elderly in Tehran. 30 male judo players were randomly divided into 2 groups, the first group (walking exercise) and the second group (control). Blood and heart variables were taken from the subjects before (24 hours before) and after the implementation of exercise programs (72 hours). The exercise protocol consisted of an 8-week walking program, which was based on Kao's (2007) article and also the suggestions of experts regarding the design and implementation of an exercise program in elderly and diabetic people who exercise three days a week and the intensity of 35% of the maximum oxygen consumption or 45% of the suggested heart rate was designed.
Results: The results of the intergroup test showed that there was a significant difference in cholesterol (P=0.020) and insulin resistance (P=0.006) in the two training and control groups. SDNN (P=0.013), rMSSD (P=0.005), HF Power (P>0.001) and LF/HF Ratio (P=0.001) had significant differences in the two training and control groups. The results of the intra-group test showed that insulin resistance (P=0.009) and LF/HF ratio (P=0.020) in the training group decreased significantly in the post-test phase compared to the pre-test. SDNN (P=0.003), rMSSD (P=0.004) and HF Power (P=0.004) in the training group increased significantly in the post-test phase compared to the pre-test.
Conclusion: According to the research results, it can be concluded that a period of walking training can lead to improvement of insulin resistance and heart rate variability in the elderly with type 2 diabetes. Therefore, these exercises are recommended as a measure to reduce cardiovascular complications in the elderly with type 2 diabetes.
