分析单次抗阻运动对外周动脉疾病 (PAD) 患者心血管参数的后效应。随机交叉。 17 名 PAD 患者进行了两次实验：对照 (C) 和阻力运动 (R)。两次训练都是相同的（8 次练习，3 × 10 次），不同之处在于 R 训练的强度在 OMNI-RES 量表中为 5-7 之间，而 C 训练是在没有任何负荷的情况下进行的。在实验室干预后一小时内测量收缩压 (BP)、舒张压、心率 (HR) 和心率压力乘积 (RPP)，并使用动态血压监测进行 24 小时测量。 R疗程后，收缩压（最大降低：-6±2 mmHg，p<0.01）和RPP（最大降低：-888±286 mmHg*bpm；p<0.01）下降，直到运动后50分钟。从运动后第 2 小时到 23 小时，R 和 C 训练期间的 BP、HR 和 RPP 乘积相似 (p>0.05)。 R 和 C 疗程之间的血压负荷、夜间血压下降和早晨血压升高也相似 (p>0.05)。在临床条件下，单次阻力运动可降低运动后一小时内的血压和心脏做功，并且不会改变 PAD 患者 24 小时内的动态心血管变量。
To analyze the post-effects of a single bout of resistance exercise on cardiovascular parameters in patients with peripheral artery disease (PAD). Randomized cross-over. Seventeen PAD patients performed two experimental sessions: control (C) and resistance exercise (R). Both sessions were identical (8 exercises, 3 × 10 reps), except that R session was performed with intensity between 5–7 in the OMNI-RES scale and the C session was performed without any load. Systolic blood pressure (BP), diastolic BP, heart rate (HR), and rate pressure product (RPP) were measured for one hour after the interventions in the laboratory, and during 24-hour using ambulatory BP monitoring. After the R session, systolic BP (greatest reduction: −6±2 mmHg, p<0.01) and RPP (greatest reduction: −888±286 mmHg*bpm; p<0.01) decreased until 50 minutes after exercise. From the second hour until 23-hour after exercise BP, HR and RPP product were similar (p>0.05) between R and C sessions. Blood pressure load, nocturnal blood pressure fall and morning surge were also similar between R and C sessions (p>0.05). A single bout of resistance exercise decreased BP and cardiac work for one hour after exercise in clinical conditions, and did not modify ambulatory cardiovascular variables during 24-hours in patients with PAD.
