The influence of power posing on cardiac vagal activity.

摘要: Abstract The effects of power posing on hormonal reactions such as testosterone and cortisol have been widely investigated, however, its the autonomic nervous system are rather unknown. Consequently, aim this study was to investigate influence cardiac vagal activity (CVA), indexed by heart rate variability. It hypothesized that high poses (HPP) would increase CVA, whereas low (LPP) decrease given is expected stress. Participants (N = 56) performed a total four poses, combination two conditions (high vs. low) body positions (sitting standing) for 1 min each, in randomized order. In addition, each pose participants were role description. Contrary our hypothesis, CVA decreased significantly during HPP comparison resting measures before after HPP, did not change LPP. Moreover, while holding pose, higher LPP than condition. Regarding subjective hypotheses confirmed, felt Additionally, perceived stress HPP. Taken together, these results suggest immediate impact PP more likely state activation within instead increasing resources cope with which may be seen only long-term basis.
