我们研究的目的是检查从事不同水平体力活动的非裔美国人的血压反应性与冷加压测试之间是否存在关联。我们对 15 名有氧运动、体力活动和 15 名体力不活动、血压正常的年轻非裔美国男性进行两分钟冷加压测试，检查了收缩压、舒张压、平均动脉压、心率、心脏指数、总外周阻力和前臂血流量。峰值耗氧量随体力活动的变化而变化，并且体力活动的受试者显着高于体力不活动的受试者（54.5 +/- 1.5 vs 36.8 +/- 0.7 ml kg(-1) min(-1)）（P<.05）。在冷加压测试中，将脚浸入冰水中，运动组和不运动组的心血管反应变化相似。这些结果表明，对于血压正常的年轻非洲裔美国男性，定期进行体力活动可能不会减弱对冷升压测试行为压力的血压反应。
The aim of our study was to examine whether there is an association between blood pressure reactivity to the cold pressor test in African Americans who engaged in different levels of physical activity. We examined the systolic pressure, diastolic pressure, mean arterial blood pressure, heart rate, cardiac index, total peripheral resistance, and forearm blood flow during a two-minute cold pressor test in 15 aerobic, physically active and 15 physically inactive, normotensive young adult African-American males. Peak oxygen consumption varied as a function of physical activity, and was significantly higher in the physically active than in the physically inactive subjects (54.5 +/- 1.5 vs 36.8 +/- 0.7 ml kg(-1) min(-1)) (P<.05). During the cold pressor test, consisting of immersing the foot in ice water, the change in cardiovascular responses were similar between the physically active and the physically inactive groups. These results suggest that regular physical activity may not contribute to an attenuated blood pressure response to behavioral stress of the cold pressor test in normotensive young adult African-American males.
