Effect of immediate haemodynamic changes of kapalbhati on healthy volunteers

AIMS OF THE STUDY: The aim of this study was to evaluate the effect of immediate haemodynamic changes of kapalabhati pranayama on healthy volunteers. OBJECTIVES: To evaluate the effects of kapalabhati pranayama on haemodynamic changes. Primary variables are Heart Rate (HR), Stroke volume (SV), Cardiac output (CO). TYPE OF THE STUDY: Single group Pre and post Experimental study. METHOD: After obtaining informed consent, the selected individuals were subjected to KB training. The training was given by qualified yoga doctors as per standard procedure. Accordingly, the subjects were made to sit in Vajrasana and to forcefully expel all of the air from the lungs while pushing the abdominal diaphragm upwards. The expulsion is active but the inhalation is passive. Subjects rapidly breathed out actively and inhaled passively through both nostrils. In this study, the KB practice conists of five rounds with fifty strokes of each round in an interval of five deep breathings in between each round. At the end of this kb practice the subjects were made to relax in Savasana for ten minutes. After obtaining their informed consent the variables (HR, SV, CO) were measured by using non-invasive method of Echocardiogram. There were 3times data collected for an each individual. The baseline data was collected before the practice of KB and post1 data was taken at the end of KB practice followed by 5 deep breathings, post2 data was taken at the end of 10 minutes relaxation in Savasana. CONCLUSION: The present study was conducted to evaluate whether the practice of KB had any influence on immediate hemodynamic changes of CO. The results showed that there is no enough evidence to show that statistically significant changes immediately after the practice of KB in Cardio dynamic parameters of Heart rate (HR), Stroke volume (SV) and Cardiac output (CO). There is enough evidence to show that statistically significant changes in Cardio dynamic parameters of Heart rate (HR), Stroke volume (SV) and Cardiac output (CO) after 10 minutes relaxation in Savasana at the end of practice of KB. There is no enough evidence to show that there is statistically significant change from the post 1 to post 2 measurements for the following parameters ―Heart rate (bpm), Stroke Volume (ml) and Cardiac Output (ml). P values are not statistically significant
