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.
在13名中年男性进行1分钟递增式自行车运动期间，由一名观察者同时测量肱动脉内血压[收缩压（AS）和舒张压（AD）]以及袖带血压[收缩压（CS）和第四相及第五相舒张压（CD）]。平均而言，平均AS比平均CS高10至11毫米汞柱，而平均AD分别比平均第四相和第五相CD高5和13毫米汞柱。在递增运动期间，AS、CS、AD和第四相CD升高，而第五相CD降低。我们还在9名年轻成年男性吸烟者进行1分钟递增式自行车运动期间测量了动脉内血压。在两组中，从静息状态到最大运动状态，平均动脉内血压以相对线性的方式升高：年轻男性的AS变化为74±5毫米汞柱（标准误），AD变化为28±3毫米汞柱；中年男性的AS变化为59±�毫米汞柱，AD变化为12±3毫米汞柱。在这群中年吸烟者中，运动期间动脉内平均血压接近动脉内测量的舒张压加2/5脉压或袖带测量的舒张压加1/2脉压，而非传统的舒张压加1/3脉压公式。
