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?

Pilot data indicate duration-dependent HRV shifts after yoga postures; leaves open optimal dosing for parasympathetic modulation in larger trials.
The Heart Rate Variability (HRV) is an important parameter to assess psychophysiological changes associated with Autonomic Nervous System (ANS). The present study aimed to assess the effect of single bout yoga postures practice on parasympathetic nervous system activity of ANS. Three male subjects having more than 5 years of experience in yoga postures were selected in the current study. These participants were assessed for HRV immediately before and after practice of specific yoga postures practiced for 15 min, 21 min and 27 min on three different days. The yoga practices were selected from hatha yogic texts that may influence brain blood flow resulting autonomic activities.
