Abstract
Background: Altered autonomic balance has been noted in Irritable bowel syndrome Regular physical
exercise may cause restoration of autonomic balance in health and disease. Objective: To assess the
effect of brisk walking on the autonomic balance by analysis of heart rate variability in patients with
Irritable bowel syndrome (IBS). Methods: This prospective study was conducted in the Department
of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU) in 2013.Seventy seven
male IBS patients aged 20-50 years, were enrolled from Gastroenterology OPD, BSMMU, Dhaka.
Twenty eight healthy sedentary male with similar age were control. HRV measures were recorded once
prior to exercise and then after 3 months of brisk walking. For assessing autonomic balance, LF/HF
ratio and Max/Min RR was evaluated by Polyrite D machine and software. ANOVA, Independent
sample t-test and paired t-test were used for statistical analysis. Results: The pre-exercise mean
values of LF/HF ratio were significantly higher (p<0.001) in all IBS patients compared to those of
control. The post exercise LF/HF ratio were significantly lower (p<0.05) in all IBS patients compared to
their pre-exercise values. Conclusion: This study concluded that the sympathovagal balance was
towards sympathetic predominance in IBS and regular moderate physical exercise may shift the
balance towards parasympathetic predominance in them.
