RESULTS

SP showed an insignificant increase in the 1st week, after which it decreased progressively. This decrease was statistically significant at 3rd and 4th week of the training period (P<0.001). DP also showed a marginal increase in the 1st week and a subsequent progressive decrease. This decrease was statistically significant at 3rd and 4th week (P<0.001). PP decreased significantly at 4th week (P<0.05). MP increased insignificantly at 1st week after which it decreased progressively, the decrease being statistically significant at 3rd and 4th week (P<0.05 and P<0.001 respectively). An insignificant decrease in HR was found at 1st week. Subsequently it showed progressive and statistically significant (P<0.001) decrease at 2nd, 3rd and 4th week. The pattern of changes in RPP was similar to that of the HR (Table I).

Before yoga training IHG test produced an increase in all the parameters mentioned above. However, the increase was significant in SP and MP (P<0.05 and P<0.001 respectively) (Table II). After four week yoga training, IHG test produced more pronounced and statistically significant increase in all the parameters. The percentage (delta) changes in the parameters before and after yoga training were found insignificant.
