To verify the acute effects of resistance exercise on post-exercise blood pressure in patients with intermittent claudication.
Eight patients randomly underwent two experimental sessions: a session of resistance exercise (R: 6 exercises, 3 sets of 12, 10 and 8 reps with a perceived exertion of 11 to 13 on the 15-grade Borg scale) and a control session (C: resting on exercise machines).
Before and for 60 min following an intervention, auscultatory blood pressure was measured while subjects rested in a sitting position. After the C session, systolic, diastolic and mean blood pressures did not change from the pre-intervention values, while these values decreased significantly after the R session throughout the entire recovery period (greatest decreases = -14 ± 5, -6 ± 5, and -9 ± 4 mmHg, respectively, P < 0.05).
After a single bout of resistance exercise patients with intermittent claudication exhibited reduced systolic, diastolic and mean blood pressures, suggesting that acute resistance exercise may decrease cardiovascular load in these patients.
验证抗阻运动对间歇性跛行患者运动后血压的急性影响。
8 名患者随机进行了两次实验：抗阻运动（R：6 项运动，3 组，每组 12、10 和 8 次重复，感知用力为 15 级 Borg 量表的 11 到 13）和对照（C：在运动机器上休息）。
在干预前和干预后 60 分钟，患者在坐姿休息时测量听诊血压。C 疗程后，收缩压、舒张压和平均血压与干预前值无变化，而 R 疗程后整个恢复期这些值显著下降（最大降幅分别为-14 ± 5、-6 ± 5 和-9 ± 4mmHg，P<0.05）。
单次抗阻运动后，间歇性跛行患者的收缩压、舒张压和平均血压均降低，提示急性抗阻运动可能降低这些患者的心血管负荷。
