Pranayama is well
known breathing exercise which is known to be improving cardiac
autonomic status. This effect mainly depends on type & duration of
Pranayama for which it is carried out.
- This study was undertaken to access the effects of both fast & slow
type pranayama done for short duration on autonomic parameters.
Materials & Methods
- The study was conducted on 60 healthy M.B.B.S. students. Pranayama
practice was carried out daily for 12 weeks which included slow as well
as fast breathing exercises. Autonomic nervous system parameters reading
were taken before & after pranayama practice. The autonomic status was
studied with non-invasive cardiovascular autonomic function tests which
included Resting Heart Rate, Basal Blood Pressure, and HRV with deep
breathing i.e. E: I Ratio, Cold Pressor Test.
There was statistically significant decrease in heart rate, systolic
blood pressure, rise of blood pressure after CPT, increase in E: I Ratio
after 12th week of Pranayama practice. Also there was
decrease in diastolic BP, but this change was not statistically
Thus results of study showed a significantly improved vagal tone and
reduced sympathetic activity after pranayama training. Thus the regular
practice of pranayama has beneficial effect on body as it reduces
harmful effect of sympathetic nervous system on cardiovascular system.
This can be applied in day today life to reduce incidence of stress
related disorders mainly hypertension, stroke, peptic ulcer.
