Additional Effect of Coherent Breathing With Aerobic Exercise on Cardiopulmonary Parameters and Quality of Life in Stage 1 Hypertensive Individuals

Hypertension, also known as high or raised blood pressure, is a condition in which the blood vessels have persistently raised pressure. A normal reading is less than 120 millimeters of mercury over less than 80 millimeters of mercury. Hypertension is a prevalent condition affecting approximately 1.28 billion individuals globally, with a significant burden observed in low- and middle-income countries such as Pakistan. Stage 1 hypertension is defined by a systolic blood pressure (SBP) between 130-139 mmHg or diastolic blood pressure (DBP) between 80-89 mmHg. High blood pressure causes no signs or symptoms, which is why healthcare providers call it a "silent killer." Non-pharmacological interventions, including aerobic exercise and breathing techniques, have shown promise in improving cardiopulmonary function and quality of life.

Coherent breathing is a controlled breathing technique that involves inhaling and exhaling at a steady, slow pace-typically around five to six breaths per minute, with each inhale and exhale lasting about six seconds. This study aims to evaluate the additional effects of coherent breathing techniques when combined with aerobic exercise, compared to aerobic exercise alone. A randomized controlled trial design will be employed. The study will be conducted over a period of 1 year at Foundation University College of Physical Therapy and Fauji Foundation Hospital Rawalpindi. Ethical approval will be obtained from ERC FUMC and IRC, and the trial will be registered with CBRC and the clinical trial registry. Data will be analyzed using SPSS version 21.0.

This study will fill a critical gap in the literature by assessing the additive benefits of coherent breathing in hypertension management. The findings may support cost-effective, non-pharmacological strategies in low-resource settings, contributing to improved public health outcomes
