Why the study?
Heart rate variability assesses psychophysiological changes of the autonomic nervous system, and the study aimed to assess the effect of a single bout of yoga postures on parasympathetic nervous system activity.
Does a single bout of yoga practices affect low frequency heart rate variability in experienced male practitioners?
