Study on Post-Exercise Blood Pressure Recovery Time in Individuals with Normal and High Body Mass Index
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 3
Abstract
Post-exercise blood pressure change and its recovery time are considered to be an indicator of cardiovascular health. Obesity and hypertension are leading co morbidities associated with adverse cardiovascular events. The aim of this study is to analyze the post-exercise blood pressure recovery time in normal weight and overweight individuals, with or without hypertension. Two-hundred subjects (all adult male only) belonging to age groups between 20 years to 50 years were selected after informed consent of the participants. The total study sample included 100 hypertensive and 100 normotensive subjects. Each group included 50 overweight individuals and 50 subjects within normal Body Mass Index (BMI). All participants were asked to perform jogging for five minutes, at the rate of 100 steps per minute. The blood pressures were recorded before and after the procedure, and the time taken for recovery of systolic blood pressure back to resting value was noted. Statistical analysis was performed using Microsoft Excel 2007 and the software SPSS20. The systolic blood pressure (SBP) increased after exercise in all four groups. However the rise was more predominant among the hypertensive population. The diastolic blood pressure decreased after exercise in normotensive, normal weight individuals; but increased in all other groups. The post-exercise blood pressure recovery time was shortest for normotensive, normal-weight subjects, and longest for hypertensive, overweight subjects. There was a strong positive correlation between body mass index and post-exercise blood pressure recovery time [R = 0.92; p < 0.00001]. In this study, we found a longer recovery time in hypertensive and overweight / obese individuals. This might be due to a raised sympathomotor or reduced vagal response in these; consistent with higher prevalence of adverse cardiovascular outcomes in these subjects.
