Although recent studies have compared the effect of progressive exercise tests to constant moderate work load tests on ankle systolic blood pressure (ASBP) and ankle to arm index (AAI) in claudicants, little is known about the relation of ASBP and AAI to work load in healthy young men. Fifteen normal volunteers were asked to cycle 40, 60, 80, 100% of VO2max. Ankle and humeral pressures were recorded simultaneously, at rest and 1 minute after the end of each test. Thereafter, AAI was calculated as the ratio of ankle to humeral systolic pressure. Compared to resting values: 134.8 +/- 13.9 mmHg, ASBP increased significantly following sub maximal tests up to 157.8 +/- 28.1 mmHg (p < 0.005), but was not increased following maximal exercise: 141.5 +/- 28.2 mmHg (NS). On the other hand, AAI showed a progressive decrease from 1.14 +/- 0.06 at rest to 1.06 +/- 0.08 (p < 0.005), but 0.98 +/- 0.07 (p < 0.005), to 0.84 +/- 0.06 (p < 0.005) and to 0.75 +/- 0.09 (p < 0.005) following 40, 60, 80 and 100% of VO2max respectively. In summary, AAI following exercise is inversely related to workload whereas ASBP is not. We suggest that when studying ankle systolic blood pressure response to heavy load exercises, results should always be compared to humeral pressure, and expressed as ankle to arms indexes.
尽管最近的研究比较了渐进式运动测试与持续中等工作负荷测试对跛行患者踝部收缩压（ASBP）和踝臂指数（AAI）的影响，但对于健康年轻男性中ASBP和AAI与工作负荷之间的关系却知之甚少。15名正常志愿者被要求以最大摄氧量（VO2max）的40%、60%、80%、100%进行骑行。在每次测试结束时的休息状态和结束1分钟后，同时记录踝部和肱部压力。此后，AAI计算为踝部收缩压与肱部收缩压之比。与静息值134.8±13.9 mmHg相比，亚极量测试后ASBP显著升高至157.8±28.1 mmHg（p<0.005），但极量运动后未升高：141.5±28.2 mmHg（无统计学意义）。另一方面，AAI从静息时的1.14±0.06逐渐下降至1.06±0.08（p<0.005），但在分别达到VO2max的40%、60%、80%和100%后，依次下降至0.98±0.07（p<0.005）、0.84±0.06（p<0.005）和0.75±0.09（p<0.005）。总之，运动后的AAI与工作负荷呈负相关，而ASBP并非如此。我们建议，在研究踝部收缩压对重负荷运动的反应时，结果应始终与肱部压力进行比较，并以踝臂指数表示。
