Role of yogic practices in individuals with hypertension and low-Peak Expiratory Flow Rate (PEFR) of Ahmedabad city

Abstract

Hypertension is one of the most important risk factors for various heart related diseases in India, especially in South-Asian region. Nowadays because of very fast life style, breathing pattern and its duration is changed considerably. Breathing duration becomes very short. The main aim of the present study was to assess the therapeutic role of yoga on various cardiovascular parameters, peak expiratory flow rate (PEFR) through pulmonary function test and peripheral capillary oxygen saturation (SpO₂), amount of oxygen in the blood in Ahmedabad population. Total 50 individuals with hypertension, low-PEFR and low-SpO₂ were selected for the present study. All participants were subjected to yoga therapy (pranayama, yoga postures and meditation) for various time intervals of 0, 3, 6, 9, and 12 months. Heart rate (HR), systolic pressure (SP), diastolic pressure (DP), pulse pressure (PP), mean arterial pressure (MAP), rate pressure product (RPP), double product (DoP), PEFR and SpO₂ were measured from all individuals at different intervals. At 0 month, all individuals had very high heart rate (HR), systolic pressure (SP), diastolic pressure (DP), pulse pressure (PP), mean arterial pressure (MAP), rate pressure product (RPP), double product (DoP), but PEFR and SpO₂ levels were very low. At the end of 12 month of yoga intervention, significant decrease in all cardiovascular parameters whereas significant elevation of PEFR and SpO₂ levels were observed. In conclusion, a comprehensive yoga therapy programme has immense potential to augment the beneficial effects of standard medical management of hypertension, lungs function and total oxygen concentration. Hence it can be used as an effective complementary therapy for heart related diseases.
