The study aims to evaluate the effects of the order of endurance and resistance exercises on postexercise blood pressure (BP) and hemodynamics in hypertensive women. Nineteen hypertensive women underwent 3 sessions: control (50 minutes rest), endurance (50-60% of heart rate reserve) followed by resistance exercise (50% of 1 repetition maximum) (E + R), and resistance followed by endurance exercise (R + E). Before and 30 minutes after each session, BP, peripheral vascular resistance, cardiac output, stroke volume, and heart rate were measured. Postexercise increases in systolic (E + R: +1 ± 3 mm Hg and R + E: +3 ± 3 mm Hg), diastolic (E + R: +3 ± 1 mm Hg and R + E: +3 ± 2 mm Hg), and mean BP (E + R: +3 ± 1 mm Hg and R + E: +3 ± 2 mm Hg) were significantly lower after the exercise sessions compared with the control session (p ≤ 0.05). The exercise sessions abolished the increases in peripheral vascular resistance (E + R: +0.00 ± 0.04 mm Hg·min·L and R + E: +0.05 ± 0.05 mm Hg·min·L) and the decreases in cardiac output (E + R: +0.04 ± 0.28 L·min and R + E: -0.26 ± 0.28 L·min) observed after the control session (p ≤ 0.05). After the exercise sessions, stroke volume decreased (E + R: -14 ± 3 ml and R + E: -9 ± 4 ml) and heart rate increased (E + R: +5 ± 1 b·min and R + E: +4 ± 1 b·min) in comparison with the control session (p ≤ 0.05). For all the variables, there were no significant differences between the exercise sessions. Regardless of the order of endurance and resistance exercises, combined exercise sessions abolished increases in BP observed in a control condition due to a reduction in peripheral vascular resistance and increases in cardiac output. Thus, combined exercises should be prescribed to individuals with hypertension to control their BP, regardless of the order they are accomplished.
该研究旨在评估耐力训练和阻力训练的顺序对高血压女性运动后血压（BP）和血液动力学的影响。19名高血压女性进行了3次训练：对照组（休息50分钟）、先进行耐力训练（心率储备的50 - 60%）然后进行阻力训练（1次重复最大值的50%）（E + R），以及先进行阻力训练然后进行耐力训练（R + E）。在每次训练前和训练后30分钟，测量血压、外周血管阻力、心输出量、每搏输出量和心率。与对照组相比，训练后收缩压（E + R：升高1±3 mmHg，R + E：升高3±3 mmHg）、舒张压（E + R：升高3±1 mmHg，R + E：升高3±2 mmHg）和平均血压（E + R：升高3±1 mmHg，R + E：升高3±2 mmHg）的升高幅度显著降低（p≤0.05）。训练消除了对照组训练后观察到的外周血管阻力升高（E + R：升高0.00±0.04 mmHg·min·L，R + E：升高0.05±0.05 mmHg·min·L）和心输出量降低（E + R：升高0.04±0.28 L·min，R + E：降低0.26±0.28 L·min）（p≤0.05）。与对照组相比，训练后每搏输出量降低（E + R：降低14±3 ml，R + E：降低9±4 ml），心率升高（E + R：升高5±1次/分钟，R + E：升高4±1次/分钟）（p≤0.05）。对于所有变量，各训练组之间均无显著差异。无论耐力训练和阻力训练的顺序如何，联合训练通过降低外周血管阻力和增加心输出量消除了在对照条件下观察到的血压升高。因此，对于高血压患者，无论训练顺序如何，均应开具联合训练处方以控制其血压。
