We aimed to determine the cardiovascular responses to two different set configuration resistance-exercise protocols during a knee extension composed of 40 repetitions with a 15RM load and a total resting time of 360 seconds. Twenty-four healthy sport science students randomly performed two sessions: (a) a long set configuration (LSC: 4 sets of 10 repetitions with 2 min rest between sets), and (b) a short set configuration (SSC: 8 sets of 5 repetitions with 51 s rest between sets). Before and during exercise, peak and mean values of heart rate, blood pressure, rate pressure product, and pulse pressure were obtained. Results showed that both protocols increased the overall peak and mean blood pressure values (p<0.001). However, LSC entailed a higher peak blood pressure response at the last set (p=0.041) and an increase throughout the first 30 repetitions (p≤0.007), whereas SSC kept steady after the first 20 repetitions. Additionally, LSC caused higher overall peak and mean heart rate and rate pressure product values (p≤0.003). Summarily, although both protocols raised blood pressure, SSC reduced the extent of the pressure and chronotropic response during resistance exercise.
我们旨在确定在膝关节伸展运动中，对于两种不同组次配置的抗阻训练方案的心血管反应。该膝关节伸展运动由使用15RM负荷进行40次重复动作且总休息时间为360秒组成。24名健康的运动科学专业学生随机进行了两个训练阶段：(a) 长组配置 (LSC：4组，每组10次重复动作，组间休息2分钟)，以及 (b) 短组配置 (SSC：8组，每组5次重复动作，组间休息51秒)。在运动前和运动期间，获取心率、血压、率压乘积和脉压的峰值和平均值。结果显示，两种方案均提高了总体血压峰值和平均值 (p<0.001)。然而，LSC在最后一组时血压峰值反应更高 (p=0.041)，并且在前30次重复动作中血压持续升高 (p≤0.007)，而SSC在最初20次重复动作后保持稳定。此外，LSC导致总体心率、率压乘积的峰值和平均值更高 (p≤0.003)。总之，尽管两种方案都会升高血压，但SSC在抗阻训练期间降低了压力和变时反应的程度。
