摘　　要：探讨普通成年人在逐级递增负荷状态下心血管机能变化特征，为全民健身中预防心血管风险事件的发生及运动负荷试验提供科学的理论依据。方法：266名20-59岁的普通成年人为对象，测定运动中各年龄段人群的心率、血压、臂踝脉搏波传播速度等血管机能评价指标的变化。结果：在40岁以下人群中，女性运动时心率上升的速度明显高于同年龄段男性，而男性血压上升的速度快于女性；40-49岁男性人群中血压上升的速度明显高于40岁以下人群，尤其是舒张压上升的速度较快，而50-59岁人群中收缩压、舒张压和脉压上升的速度始终处于“领先”地位的阶段，且和其他年龄段形成明显的差异；40-49岁男性和50-59岁组女性因心电和血压的异常而终止运动人数百分比明显高于同性别其他年龄段人群。结论：随着年龄的增长，运动中发生心血管风险事件的机率也会增加，40-49岁男性和50-59岁女性可能是运动中心血管风险事件的高发年龄段。Observed the changes of vascular function in Graded Exercise Testing in Adults, for the prevention of cardio- vascular risk events in national fitness and exercise testing to provide a scientific basis. Method： In accordance with the principle of voluntary participation, this research selected 266 adults aged 20- 59 years who worked in Haidian district enterprises and institutions. Using incremental cycle ergometer stress test, this research observe dynamic changes of eachage groups＇ heart rote,blood pressure,Brachialankle pulse wave velocity（ha- PWV）. Result： In the 40 years of age, during exercise vmrnen＇s heart rate was increeased significantly higher than the same age men, while men＇s blood pressure increased faster than fenales; the rate of rise in blood pressure of 40-49 years old male populaticrt was higher than40 years of age, espedaUy the diastolic blood pressure rising fast, the SBP DBP and PP of 50-59 group＇s is always in- creased in ＂leading＂stattts of the stage, formation of significant difference VS other age groups. 40-49 male and 50- 59 female age group ECG and blood pressure due to abnomal termination of exercise was significantly higher than the per-centage of sex with other age groups. Conclusion. With age, the risk of incident cardiovascular movement will increase the probability of 40 - 49 men and women aged 50 - 59 may be a movement cardiovascular events in high risk age group.
