The purpose of this study was to compare blood pressure and heart rate variability responses in physically active men after performing resistance training sessions with rest intervals of 1 min, 2 min and 3 min. Eighteen men (age, 21.6±1.1 years; body mass, 74.1±8.1 kg; body height, 175.3±7.1 cm) who performed 180min of physical activity per week participated in this study. After determining the 15RM loads for the squat, bench press, bent-over row and deadlift, participants performed a resistance training session. Participants performed three resistance training protocols in randomized counterbalanced order. Each experimental protocol comprised different rest intervals between sets of resistance training exercises (1min, 2min or 3min). During each experimental session, participants performed three sets with a 15RM load. Blood pressure and heart rate variability were measured before and for 2h after each session. The results demonstrated a greater blood pressure (p<0.05) reduction with a longer rest interval. There was no statistically significant difference in heart rate variability changes between groups. These results indicate that 2min and 3min rest intervals while using a 15RM load provide the best stimulus for a blood pressure reduction response after a resistance training session. Our findings suggest that strength and conditioning professionals should prescribe 2min or 3min rest intervals when resistance training is performed with a 15RM load if the aim is to obtain an acute reduction in blood pressure after a resistance training session.
本研究的目的是比较进行阻力训练时，休息间隔为1分钟、2分钟和3分钟的情况下，身体活跃的男性的血压和心率变异性反应。18名每周进行180分钟体育活动的男性（年龄21.6±1.1岁；体重74.1±8.1千克；身高175.3±7.1厘米）参与了本研究。在确定深蹲、卧推、俯身划船和硬拉的15RM负荷后，参与者进行了一次阻力训练。参与者以随机平衡顺序进行了三种阻力训练方案。每个实验方案包括阻力训练组间不同的休息间隔（1分钟、2分钟或3分钟）。在每个实验环节中，参与者以15RM负荷进行三组训练。在每个环节前后以及之后2小时测量血压和心率变异性。结果表明，休息间隔越长，血压降低幅度越大（p<0.05）。各组间心率变异性变化无统计学显著差异。这些结果表明，在使用15RM负荷进行阻力训练时，2分钟和3分钟的休息间隔能为训练后血压降低反应提供最佳刺激。我们的研究结果表明，如果目标是在阻力训练后实现血压急性降低，那么力量与体能训练专业人员在以15RM负荷进行阻力训练时应规定2分钟或3分钟的休息间隔。
