Objectives- To study the effect of pranayama training on cardiovascular parameters. Design- Longitudinal study. Settings/Location- Government Dental College, Aurangabad. Subjects- 60 Normal healthy females and males volunteers in the age group of 30 to 50 years ready to give consent. Subjects were divided randomly into two groups of 30 individuals act as subjects and control. Trial was registered under WHO and CTRI trial registry systems. CTRI registration no. is CTRI/2012/03/002512 and WHO registry no. is UTN- U1111-1129-2155. Interventions- Pranayama training camp will be conducted 45 minutes daily for 1 month. The exercises include slow and fast breathing exercises like ‘nadishuddhi’, ‘mukh-bhastrika’, ‘pranav’ and ‘savitripranayama’. Outcome Measures- Cardiovascular efficiency will be tested by using parameters like

Systolic blood pressure
Diastolic blood pressure
Heart rate and Systolic time intervals involving pre-ejection period (PEP), left ventricular ejection time (LVET), total mechanical systole (QS₂) & PEP/LVET ratio.

Results- Pranayama training for 1 month resulted in significant decrease in systolic blood pressure (<0.0001) & LVET (<0.0001) whereas QS2 (<0.0001) and PEP (<0.0001) were increased significantly.PEP/LVET ratio which is a sensitive index of cardiac performance was significantly increased after the training. Conclusion- Our study shows that pranayama training improves ventricular performance by increasing parasympathetic activity.
