Abstract

Objective: Exercise blood pressure (BP) and 24-hour ambulatory blood pressure monitoring (24-H ABPM) are stronger predictors of cardiovascular disease as compared to resting BP. Hence, a randomized control trial was conducted to determine the effect of graded aerobic exercise for eight weeks on exercise BP and 24-H ABPM in women with elevated BP. Methods: Exercise group (EG, n = 6) underwent 8 weeks aerobic exercise. The first month consisted of training at 50% heart rate reserve (HRR), 30 minutes per session 3 times per week, and this was then increased to 70% HRR 45 minutes per session for the next 4 weeks. The control group (CG, n = 7) continued with their normal routine. The baseline parameters included resting BP, submaximal and maximal exercise BP, 24-H ABPM and aerobic capacity (VO2peak), which were repeated at 4 and 8 weeks. Results were analyzed with ANOVA repeated measures. Results: After 4 weeks, despite a significant reduction observed on resting systolic BP (SBP) in both groups, only the EG had reduction in submaximal exercise SBP (-17 mmHg, P < 0.01). Although both groups had significant reduction in maximal exercise SBP at 8 weeks (P < 0.05), the EG achieved it at higher VO2peak compared to the CG (21.15±4.82 vs. 16.94±2.32 ml/kg/min). No significant changes were observed in 24-H ABPM in both groups. Conclusion: For sedentary women with elevated BP, the prescribed regime is beneficial for sub maximal exercise SBP reduction, which needs to be increased in frequency in accordance to American Heart Association (AHA) recommendation for further improvement of cardiorespiratory fitness.
