Study Aim: Aim of this investigation was to determining the effect of 3-weeks of Surya Nadi Pranayama on Maximal Oxygen Consumption (VO2 max).
Material and Methods: Twenty-four, university level girls of Department of Physical Education (T), Guru Nanak Dev University, Amritsar between the age group of 21 - 26 years volunteered to participate in the study. The subjects were purposively assigned into two groups: Group-A: Experimental (n1 = 12) and Group-B: Control (n2 = 12). All the subjects were informed about the objective and protocol of the study. The sample size (N=24) was calculated using the G*Power 220.127.116.11 software. A power of 0.80 (1-β err prob) and significance level (α) of 0.05. Cooper’s 12-minute run test was used to measure maximal oxygen consumption (VO2 max).
Statistics: Statistical analyses were performed using the Statistical Package for the Social Sciences for Windows version 16.0 software (SPSS Inc., Chicago, IL). Data is expressed as the mean ± SD. Student t test for paired samples was utilized to compare the means of the pre-test and the post-test. The level of significance was set at 0.05.
Results: The t-value in case of experimental group was 0.843 and for control group it was 0.312. The data does suggest that the differences between pre-test and post-test of Maximal Oxygen Consumption (VO2 max) in experimental and control group are insignificant.
