Effect of Pratiloma Pranayama on Heart Rate Variability Among Healthy Individuals-A Randomized Controlled Trial

Pranayama is a yogic breathing practice that refers to controlling the life force or extension of breathing pattern. pratiloma pranayama plays a significant role in regulating the cardiac autonomic function.During deep inspiration, vagal activity decreases, increasing heart rate. During expiration, vagal activity restores, slowing heart rate. This variation is measured as the expiratory:inspiratory ratio using R-R intervals and it’s parameter’s such as the Heart rate variability.All theeligible study participants will be divided into two groups, Study group and control group by simple randomization.Participants will be randomly divided (1:1 ratio) into study and control groups using simple random methods with the use of computerized randomization.inclusion criteria with 18 – 35 years Gender – Both male and female Healthy participant with their consent Not having any previous systemic illness.The study group will receive five rounds of Pratiloma pranayama for 20 minutes. While the control group will be at rest in sitting position for 20 minutes per day for a period of 21days.Control group will be advised to concentrate on their breathing in sitting position for 20 min for the 21 days.primary outcome of HRV will be assesed on baseline and 21 days.secondary outcome of blood pressure will be assesed on baseline and 21 days.
