: Post-exercise hypotension, the reduction of blood pressure after a bout of exercise, is of great clinical relevance. Resistance exercise training is considered an important contribution to exercise training programs for hypertensive individuals and athletes. In this context, post-exercise hypotension could be clinically relevant because it would maintain blood pressure of hypertensive individuals transiently at lower levels during day-time intervals, when blood pressure is typically at its highest levels. The aim of this study was to compare the post-exercise cardiovascular effects on Paralympic powerlifting athletes of two typical high-intensity resistance-training sessions, using either five sets of five bench press repetitions at 90% 1 repetition maximum (1RM) or five sets of three bench press repetitions at 95% 1RM. : Ten national-level Paralympic weightlifting athletes (age: 26.1 ± 6.9 years; body mass: 76.8 ± 17.4 kg) completed the two resistance-training sessions, one week apart, in a random order. : Compared with baseline values, a reduction of 5-9% in systolic blood pressure was observed after 90% and 95% of 1RM at 20-50 min post-exercise. Furthermore, myocardial oxygen volume and double product were only significantly increased immediately after and 5 min post-exercise, while the heart rate was significantly elevated after the resistance training but decreased to baseline level by 50 min after training for both training conditions. : A hypotensive response can be expected in elite Paralympic powerlifting athletes after typical high-intensity type resistance-training sessions.
运动后低血压,即在运动后血压降低,具有重要的临床意义。阻力训练被认为是高血压患者和运动员运动训练计划的重要贡献。在这种情况下,运动后低血压可能具有临床意义,因为它可以使高血压患者的血压在白天的间隔时间内暂时保持在较低水平,而白天的血压通常处于最高水平。本研究的目的是比较两种典型的高强度阻力训练对残奥会举重运动员的运动后心血管效应,即使用 90% 1 重复最大强度(1RM)的 5 组 5 次卧推重复或 95% 1RM 的 5 组 3 次卧推重复。
10 名国家级残奥会举重运动员(年龄:26.1±6.9 岁;体重:76.8±17.4 公斤)以随机顺序在一周内完成了这两种阻力训练。与基线值相比,在运动后 20-50 分钟,收缩压降低了 5-9%,使用 90%和 95%的 1RM。此外,心肌氧容量和双乘积仅在运动后即刻和 5 分钟后显著增加,而心率在阻力训练后显著升高,但在训练后 50 分钟降至基线水平,两种训练条件均如此。
在典型的高强度类型的阻力训练后,精英残奥会举重运动员可能会出现低血压反应。
