Intra-arterial and cuff blood pressure responses during incremental cycle ergometry.

Brachial intra-arterial blood pressure [systolic (AS) and diastolic (AD)] and cuff blood pressure [systolic (CS) and fourth- and fifth-phase diastolic (CD)] were simultaneously measured by a single observer in 13 middle-aged men during 1-min incremental cycle exercise. On the average, the mean AS exceeded the mean CS by 10 to 11 mm Hg, while the mean AD exceeded the average fourth and fifth CD by 5 and 13 mm Hg, respectively. During incremental exercise, AS, CS, AD, and fourth-phase CD increased, while fifth-phase CD decreased. We also measured intra-arterial blood pressure in nine young adult men smokers during 1-min incremental cycle exercise. In both groups, the average intra-arterial blood pressures increased in a relatively linear fashion from rest to maximal exercise: AS change = 74 +/- 5 mm Hg (SE) and AD change = 28 +/- 3 mm Hg for young men; AS change = 59 +/- 5 mm Hg and AD change = 12 +/- 3 mm Hg for middle-aged men. In this population of middle-aged smokers, intra-arterial mean blood pressure during exercise approximated diastolic plus 2/5 pulse pressure for intra-arterial measures or diastolic plus 1/2 pulse pressure for cuff measures rather than the traditional formula of diastolic plus 1/3 pulse pressure.

臂内血压[收缩期（AS）和舒张压（AD）]和袖口血压[收缩期（CS）和第四和五相舒张期（CD）]，同时通过13个中年的单个观察者在13个中期中测量男性在1分钟的增量周期运动中。平均而言，平均值超过平均CS的平均值分别超过10至11 mm Hg，而平均值AD分别超过了第四和第五CD，分别超过5和13 mm Hg。在增量运动过程中，AS，CS，AD和第四阶段CD增加，而第五阶段CD降低。我们还测量了在1分钟的增量周期运动中，在九名年轻成年男性吸烟者中测量了动脉内血压。在这两组中，从休息到最大练习的相对线性方式的平均动脉内血压增加：年轻男性的变化= 74 +/- 5 mm Hg（SE）和AD变化= 28 +/- 3 mm Hg ;随着变化= 59 +/- 5 mm Hg和AD变化= 12 +/- 3 mm Hg的中级男性。在这种中年吸烟者的种群中，运动中动脉内平均血压近似舒张压加上2/5的脉压 - 动脉内措施或舒张压加1/2的袖口措施，而不是传统的舒张期和1/2 /3脉压。
