Background: The purpose of this study was to investigate the correlation between yoga and autonomic nervous system in women with metabolic syndrome.
Methods: A randomized controlled study was performed in participants recruited from a public center for managing chronic diseases located in Gyeong-gi Province. The 39 women participants diagnosed with metabolic syndrome were randomly assigned to the 12-week yoga exercise group (n=22) or the wait-listed control group (n=17). Biochemical laboratory tests and heart rate variability were measured before and after the 12-week program.
Results: In post-menopausal women, the low frequency power of frequency domain significantly decreased in the yoga exercise group compared to the control group (P=0.07). On the time domain of heart rate variability and metabolic syndrome components, there were no significant differences between the groups.
Conclusions: Sympathetic activity was decreased in post-menopausal women with metabolic syndrome who practiced yoga. Our results suggest that yoga might be beneficial in improving the autonomic nervous system in post-menopausal women with metabolic syndrome.
