Immediate effect of Tadagi Mudra on Heart Rate Variability (HRV) among Healthy Individuals: A Study Protocol of a Randomized Controlled Trial

Background: Tadagi Mudra, is a Yogic Mudra practice that involves deep diaphragmatic breathing with abdominal expansion. In this study, the protocol aims to investigate the immediate effect of Tadagi Mudra on HRV in healthy individuals. Methodology: This randomised controlled trial study design will be conducted at the Host Institution. A total of eighty participants will be randomly allocated to intervention (40) and control group (40). The intervention group will practice Tadagi Mudra of deep diaphragmatic breathing with abdominal expansion and the control group will practice simple natural breathing for 20 minutes. The primary and secondary outcomes will be Heart rate variability and blood pressure before and immediately after intervention. Data analysis will use R software to determine the effects of Tadagi Mudra on autonomic and cardiac function. Discussion: Ancient yogic techniques of mudras are believed to influence pranic or energy channels to regulate autonomic functions, despite limited, previous studies indicate the importance of Gyan and Shunya mudra on parasympathetic enhancement. However, this study seeks to explore the immediate effects of Tadagi Mudra on HRV, contributing evidence to the growing body of research on the autonomic and therapeutic benefits of mudra practices.
