Abstract
Background: Comparative cardiovascular responses to treadmill and bicycle ergometer (bike) exercise tests in hypertensive Nigerians are not known. This study compared cardiovascular responses to the two modes of exercise testing in hypertensives using maximal exercise protocols.
Methods: One hundred and ten male subjects with mild-to-moderate hypertension underwent maximal treadmill and bike test one after the other at a single visit in a simple random manner. Paired-sampled t-test was used to compare responses to both exercise tests while chi-squared test was used to compare categorical variables.
Results: The maximal heart rate (P<0.001), peak systolic blood pressure (P=0.02), rate pressure product (P<0.001), peak oxygen uptake (P<0.001), and exercise capacity (P<0.001) in metabolic equivalents were signifcantly higher on the treadmill than on the bike.
Conclusion: Higher cardiovascular responses on treadmill in Nigerian male hypertensives in this study, similar to findings in non-hypertensives and non-Nigerians in earlier studies, suggest that treadmill may be of better diagnostic utility in our population.
背景：尼日利亚高血压患者对跑步机和自行车测力计（自行车）运动测试的心血管反应比较尚不清楚。本研究采用最大运动方案，比较了高血压患者对两种运动测试模式的心血管反应：方法：110 名患有轻度至中度高血压的男性受试者在一次就诊中以简单随机的方式先后接受了最大跑步机和自行车测试。采用配对抽样 t 检验比较两种运动测试的反应，采用卡方检验比较分类变量：结果：最大心率（PConclusion：本研究中，尼日利亚男性高血压患者在跑步机上的心血管反应较高，这与早期研究中对非高血压患者和非尼日利亚人的研究结果相似，表明跑步机在我国人群中可能具有更好的诊断效用。
