P36 Pulse Wave Velocity (PWV) Responses to 3 Months of Yoga Poses and Respiratory Control (Ujjayi Pranayama) in Hypertensive Post Menopause Women: Randomized Clinical Trial

Abstract

Background

Non-pharmacological management of hypertension includes regular exercises. Yoga has been pointed as effective on treatment of hypertension. Its many aspects like yoga poses (asanas), respiratory control (pranayamas), meditation and others have not yet been assessed separately to understant its effects on cardiovascular issues. Thus, this study aims to partially clear the effects of yoga poses including exclusive muscle contraction known as bandhas (pelvic floor, core and throat), a specific respiratory technique ujjayi pranayama, whose translation is victory breath and active control group composed of stretching exercises on PWV.

Methods

Randomized trial assessing carotid femoral pulse wave velocity (cfPWV) by Complior®. Hypertensive post menopause women (HPMW) non-obese and non-smokers randomized in 4 groups (1- yoga poses + ujjayi; 2-yoga poses, 3- stretching exercises + ujjayi, 4- stretching exercises) attending 60 minutes assisted video classes twice a week (24 sessions). Data are presented as mean(M) ± standard error (SE). Generalized estimation equation (GEE) was used to data analysis, p ≤ 0,05.

Results

24 women recruited, randomized, 15 concluded study (1− n = 3; 2− n = 6; 3− n = 4; 4− n = 2). Group 1 showed cfPWV at 10, 0 ± 0, 23 m/s; 2− 8,9 ± 0,29 m/s; 3− 7.7 ± 0,53 m/s; 4− 8.8 ± 0,24 m/s at baseline. Post intervention presented 1− −1,8 ± 0,31 m/s p = 0,00; 2− −0,43 ± 0,25 m/s p = 0,08; 3− −1,4 ± 0,27 m/s p = 0,00; 4− 1,4 ± 0,99 m/s p = 0,16.

Conclusion

The present study has demonstrated an effect of respiratory control ujjayi pranayama on cfPWV after 3 months in HPMW.
