The objective of the study was to find the effect of six weeks bhastrika pranayama training on physiological variables among school girls. For the purpose of the study twenty four (24) school girls from Government High School Sarangpur, Chandigarh was selected. The age of the subject ranged between 14-15 years. Total numbers of subjects were divided into two groups i.e. experimental group (12) and control group (12). Experimental group was given Bhastrika Pranayama, control group was not given any kind of training. The training programmed was scheduled for 6 weeks by the researcher. It was 45 minutes pranayama training for 5 days in a week. All groups were pre and post tested on physiological variables (vital capacity, systolic blood pressure, diastolic blood pressure, breath hold capacity, resting pulse rate and respiratory rate). The data was analyzed by employing pair ‘t’-test. The level of significance was set at 0.05. Statistical on gathered data showed that there were significant differences found on vital capacity, systolic blood pressure, diastolic blood pressure, breath hold capacity, resting pulse rate and respiratory rate. The control group showed no significant differences found on physiological variables.
