Limited data suggest that physical activity increases postexercise blood pressure in African-American women. The purpose of this study was to evaluate the postexercise blood pressure response to acute exercise in normotensive young adult African-American women.
Eight healthy women (age 22.5+/-.9 years) performed a cycle ergometer bout of 30 minutes at 60% of peak ventilatory oxygen uptake (VO2 peak). Control arterial blood pressure, heart rate, lower leg blood flow, cardiac output, spectral analysis of blood pressure, heart rate variability, and baroreceptor sensitivity were measured for 5 minutes before exercise and were compared to postexercise measurements performed at rest intervals of 15-20, 35-40 and 55-60 minutes after exercise.
Exercise performed at 60% VO2 peak produced an arterial pressure of 172+/-10/ 70.1+/-4.0 mm Hg. Postexercise recovery values were not significantly different than the baseline control values.
These results do not support the hypothesis that acute physical activity exerts an adverse effect on postexercise blood pressure in African American women.
有限的数据表明，体育活动会使非裔美国女性运动后的血压升高。本研究的目的是评估血压正常的年轻成年非裔美国女性急性运动后血压的反应。
8名健康女性（年龄22.5±0.9岁）以峰值通气摄氧量（VO2峰值）的60%进行了30分钟的自行车测力计运动。在运动前测量5分钟的对照动脉血压、心率、小腿血流量、心输出量、血压频谱分析、心率变异性和压力感受器敏感性，并与运动后15 - 20、35 - 40和55 - 60分钟休息间隔时的运动后测量值进行比较。
以VO2峰值的60%进行运动产生的动脉压为172±10/70.1±4.0毫米汞柱。运动后恢复值与基线对照值无显著差异。
这些结果不支持急性体育活动会对非裔美国女性运动后血压产生不利影响这一假设。
