摘要：Malik S, Shah M, Hasan S, Bilal M. The Physiological Responses of Yogic Breathing Techniques: A Case-Control Study. JEPonline 2011;14(3):74-79. The purpose of this study was to assess the effects of Yogic breathing techniques (Ujjaiya, Bhastrica and Humsa) on heart rate (HR), systolic blood pressure (SBP), and peak expiratory flow rate (PEFR). The Treatment Group consisted of 100 subjects while Control Group consisted of 50 subjects. All subjects signed an informed consent. Physical characteristics (age, height, and weight) were recorded and medical history was obtained from both groups of subjects. The subjects’ cardiorespiratory responses were assessed before and after the pranayama (Yogic breathing) session. Yogic breathing techniques were demonstrated and practiced for 1 hr by the Treatment Group under expert guidance, while the Control Group sat quietly. The data were analyzed using SPSS 17 and Student t-tests. When the before and after data were analyzed in each group, the mean values for HR and SBP in the treatment group were significantly decreased after the pranayama session while PEFR was significantly increased. Yogic breathing improved the subjects’ cardiorespiratory responses in the Treatment Group. Further study is required to understand how long the positive hemodynamic responses continue to produce positive health benefits, and the degree to which individuals with hypertension and asthma will benefit from Yogic breathing.
