| Popis: | Background and Aims: The sedentary lifestyle in individuals with metabolic syndrome is a main threatening risk for their health. This study aimed to investigate the effects of aerobic exercise with 65% of maximal oxygen consumption on heart rate variability and vascular nitric oxide levels in middle-aged males with metabolic syndrome. Materials and Methods: In total, 30 middle-aged men with metabolic syndrome were randomly divided into control and aerobic training groups. At the pretest and posttest, the values of metabolic risk indices, heart rate variability, and nitric oxide were measured in both groups. The aerobic training group performed aerobic exercise for eight weeks at 65% of maximal oxygen consumption. The data were analyzed using the independent and paired t-tests. Results: According to the results, after comparing the values obtained from the posttest and pretest, there was a significant difference between the training and control groups regarding the fasting blood glucose, triglyceride, metabolic Z score, Standard deviation of NN intervals (SDNN), Square root of the mean squared differences of successive NN intervals (rMSSD), very-low-frequency (VLF), High frequency (HF), and vascular nitric oxide levels. Total cholesterol and low-density lipoprotein levels were significantly different in the aerobic training group, compared to those of the control group and LF as well as LF/HF at the pretest (P=0.01). However, despite slight changes in high lipoprotein and blood pressure levels, there was no significant difference in the aerobic training group, compared to the control group and pre-test. Conclusion: Regular moderate-intensity aerobic exercise can be used as an appropriate exercise protocol to improve cardiovascular function for males with metabolic syndrome. |
