Abstract:

Background: Pranayama has a very important role in the yogic system of exercises for keeping sound health. Bhastrika Pranayama imitates the action of the 'Bhastika' or 'bellows' & fans the internal fire, heating the physical & subtle bodies. The most important physiological effects of Bhastrika is on the brain & heart. It stimulates the circulation of cerebral fluid & increases the compression & decompression upon brain, creating a rhythmic massage. There is a lack of study on particular discipline and hence the present study has been undertaken to examine the effects of bhastrika pranayama on the HR, BP, MEP & PEFR.

Aim: To determine the effects of Bhastrika pranayama on Blood Pressure, Heart Rate, MEP & PEFR.

Materials & Methods: The study was conducted on 50 medical students (age: 18-25 yrs). BP, HR, MEP & PEFR were recorded using standard instrument before & after the pranayama. Paired 't' test was applied to obtain the statistical significance.

Results: Significant decrease in SBP [before:117.84 ± 6.86 after:111.34 ± 4.54 mmHg, (p≤0.000)] and DBP [before: 80.32 ± 7.97, after: 77 ± 3.98 mmHg, ( p≤ 0.000)] and significant increase in Mean HR [before: 70.38 ± 7.39, after:79.08 ± 5.59bpm, (p≤0.000)] ,MEP [before: 33.22 +-15.63 after: 43.2+-17.46, (p≤ 0.000)] and PEFR [before: 223.2+-64.56, after: 280 +-67.35 (p≤ 0.000)] observed as a immediate effect of bhastrika pranayama. Conclusion: Bhastrika pranayama is found effective in decreasing BP and increasing HR immediately. Significant increase in pulmonary parameters like MEP and PEFR was found. It suggests that practice of pranayama helps in improvement of cardiopulmonary functions.
