急性有氧运动会产生运动后低血压（PEH）。中国人群的心血管疾病患病率低于白人。PEH可能通过其对高血压的影响而与心血管疾病相关。本研究的目的是比较白人和中国受试者在急性有氧运动后的PEH。62名受试者（30名白人和32名中国人，50%男性）在45 min跑台运动后30 min和60 min进行外周和中心血流动力学测量以及动脉和心脏评价。高加索人的基线血压显著高于中国人。虽然高加索人肱动脉收缩压的降低幅度大于中国人，但两组之间颈动脉收缩压的变化没有差异。中国受试者的心输出量和心率增加幅度大于白人受试者，但中国受试者和白人受试者的总外周阻力和腿部脉搏波速度降低幅度相似。我们的结论是，与中国受试者相比，急性有氧运动对高加索人外周收缩压产生更大幅度的PEH。PEH的不同幅度是由心率介导的心输出量增加更大引起的，而每搏输出量没有变化。种族之间的初始BP差异可能影响了研究结果。
Acute aerobic exercise produces post-exercise hypotension (PEH). Chinese populations have lower prevalence of cardiovascular disease compared to Caucasians. PEH may be associated cardiovascular disease through its influence on hypertension. The purpose of this study was to compare PEH between Caucasian and Chinese subjects following acute aerobic exercise. 62 (30 Caucasian and 32 Chinese, 50% male) subjects underwent measurement of peripheral and central hemodynamics as well as arterial and cardiac evaluations, 30 min and 60 min after 45 min of treadmill exercise. Caucasians exhibited significantly higher baseline BP than the Chinese. While the reduction in brachial artery systolic BP was greater in Caucasian than in the Chinese, there was no difference in changes in carotid systolic BP between the groups. The increase in cardiac output and heart rate was greater in the Chinese than Caucasians, but total peripheral resistance and leg pulse wave velocity decreased by a similar magnitude in the Chinese and Caucasian subjects. We conclude that acute aerobic exercise produces a greater magnitude of PEH in peripheral systolic BP in Caucasian compared to Chinese subjects. The different magnitude in PEH was caused by the greater increase in cardiac output mediated by heart rate, with no change in stroke volume. It is possible that initial BP differences between races influenced the findings.
