Hypertension remains one of the most important preventable contributors to morbidity and mortality. Physical activity of moderate intensity has been recommended for the prevention and complementary treatment of hypertension and to improve longevity. We hypothesised that moderate-intensity aerobic exercise would result in improving relative cardiovascular parameters of primary and secondary hypertensive patients. This study was a multi-centre randomised controlled trial. In this study, a 6-weeks programme of moderate-intensity exercise using cycle-ergometer was administered to both primary and secondary hypertensive experimental groups compared with primary and secondary hypertensive control groups. The outcome measures (Systolic Blood Pressure―SBP, Diastolic Blood Pressure―DBP, and Heart Rate―HR) were assessed at baseline and 6 weeks. Analyses were conducted using two-way analysis of variance (ANOVA) for between groups comparison. Paired t-test was used to determine within group differences. Sixty nine (69) participants with a mean ± SD age of 40.89 ± 8.23 years completed the study. Significant positive reduction in SBP 9.91–9.36 mmHg and DBP 10.5–9.94 mmHg were observed between baseline and 6 weeks in the experimental groups. However, the reduction in SBP and DBP were observed in the experimental groups compared with the control groups. No positive change in HR across the groups was observed. These results demonstrate the possible benefits of short-term moderate-intensity aerobic exercise training on both primary and secondary hypertension. PACTR201902490588010 [ABSTRACT FROM AUTHOR]

Physical activity has been recommended for the prevention and complementary treatment of hypertension. The objective of this research is to compare the responses of relative cardiovascular parameters of primary and secondary hypertensive patients to moderate-intensity aerobic exercise. One hundred participants are expected to be recruited and randomised into four groups, namely, the Primary Hypertension, and Secondary Hypertension Experimental groups, primary Hypertension and Secondary Hypertension Control groups. The participants in the experimental groups will undergo cycle-ergometer training, 3 per week, for 30 minutes, while the control groups will be non-exercise control. Participants' blood pressure will be measured using a calibrated digital monitor, heart rate (HR) will be measured using a fingertip digital pulse oximeter, and rate pressure product (RPP) will be calculated by multiplying systolic BP and HR at baseline and the end of 6weeks. Data will be analysed using descriptive and inferential statistics, multivariate analysis for between the groups and paired t-test within the group. Alpha will be set at 0.05. Though different additional strategies such as exercise and lifestyle modifications exist for the control of hypertension. But no strategies have been identified to compare the cardiovascular responses of primary and secondary hypertensive patients to moderate-intensity aerobic exercise. [ABSTRACT FROM AUTHOR]
