Effect of 10 cm Loaded Inspiratory Training when Compared to 20 cm Loaded Training in Controlling Hypertension

Abstract

Background Slow breathing especially with prolonged exhalation appears to reduce sympathetic nerve traffic and thus causes arteriolar dilatation. Loaded inspiratory exercise has been demonstrated in studies to lower blood pressure. However the optimal intensity and duration of loaded training to control hypertension is not known. The objective of the present study was to compare the effect of 10 cm loaded inspiratory training with that of 20 cm loaded training in controlling hypertension after third and sixth week.Methodology Thirty subjects with essential hypertension stage I or II were included and randomized into two groups. Group A received inspiratory loaded training with 20 cm of water loaded training and Group B received inspiratory loaded training with 10 cm of water loaded training. Training was performed at home for 30 minutes every day twice daily for 3 weeks. Blood pressure was measured at baseline before the intervention after 3rd and 6th week.Results Both the groups showed statistically significant reduction in blood pressure after six weeks of loaded training plt.0001. However on comparing the groups both the groups were equally effective in reducing blood pressure after 3rd and 6th week of training p values ndash Systolic gt.850 gt.268 Diastolic gt.761gt.304 respectively.Conclusion Loaded training can reduce both systolic and diastolic hypertension after six weeks of training. There was no difference in effectiveness of 10 cm loaded inspiratory training when compared to 20 cm loaded training in controlling hypertension after 3rd and 6th week.
