摘要：Malik S, Shah M, Hasan S, Bilal M. The Physiological Responses ofYogic Breathing Techniques: A Case-Control Study. JEPonline2011;14(3):74-79. The purpose of this study was to assess theeffects of Yogic breathing techniques (Ujjaiya, Bhastrica and Humsa)on heart rate (HR), systolic blood pressure (SBP), and peak expiratoryflow rate (PEFR). The Treatment Group consisted of 100 subjectswhile Control Group consisted of 50 subjects. All subjects signed aninformed consent. Physical characteristics (age, height, and weight)were recorded and medical history was obtained from both groups ofsubjects. The subjects’ cardiorespiratory responses were assessedbefore and after the pranayama (Yogic breathing) session. Yogicbreathing techniques were demonstrated and practiced for 1 hr by theTreatment Group under expert guidance, while the Control Group satquietly. The data were analyzed using SPSS 17 and Student t-tests.When the before and after data were analyzed in each group, themean values for HR and SBP in the treatment group were significantlydecreased after the pranayama session while PEFR was significantlyincreased. Yogic breathing improved the subjects’ cardiorespiratoryresponses in the Treatment Group. Further study is required tounderstand how long the positive hemodynamic responses continueto produce positive health benefits, and the degree to whichindividuals with hypertension and asthma will benefit from Yogicbreathing.
