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
在尼日利亚高血压患者中，跑步机运动试验和自行车测力计（自行车）运动试验的心血管反应对比情况尚不清楚。本研究使用最大运动方案，比较了高血压患者对这两种运动测试方式的心血管反应。
方法
110名轻度至中度高血压男性受试者在一次就诊时以简单随机的方式先后进行最大跑步机测试和自行车测试。配对样本t检验用于比较两种运动测试的反应，卡方检验用于比较分类变量。
结果
跑步机测试时，最大心率（P<0.001）、收缩压峰值（P=0.02）、心率血压乘积（P<0.001）、最大摄氧量（P<0.001）以及代谢当量表示的运动能力（P<0.001）均显著高于自行车测试。
结论
本研究中尼日利亚男性高血压患者在跑步机测试时出现更高的心血管反应，这与早期研究中非高血压患者和非尼日利亚人群的结果相似，表明跑步机在我们的人群中可能具有更好的诊断效用。
