In order to investigate the influence of high-velocity circuit resistance training on maximal aerobic power, maximal stroke volume and cardiac output, and blood lactate removal during recovery, 16 habitually active males were blocked on initial VO2max into either training or control groups. The training group completed two (weeks 1 and 2) or three (weeks 3-6) circuits of 10 variable-resistance hydraulic exercise stations at an exercise: relief ratio of 1:2 on alternate days over six weeks. Angular velocities of movement were maintained at approximately 3.1 rad.s-1. Following training, the VO2max was increased (p less than .01) from 4.32 to 4.68 1.min-1. Maximal stroke volume was increased (p less than .05) from 120 to 129 mL and heart rate response to an absolute submaximal exercise load was decreased (p less than .05) from 153 to 146 beats.min-1. As well, enhanced (p less than .01) removal of lactate from the blood was observed during recovery from exhausting exercise. No changes were observed for control subjects. These results indicate that positive alterations in aerobic and cardiovascular function may be achieved consequent to high-velocity circuit resistance training.
为了研究高速循环抗阻训练对最大摄氧量、最大每搏输出量和心输出量以及恢复过程中血乳酸清除的影响，16名经常运动的男性根据初始最大摄氧量被分为训练组或对照组。训练组在六周内隔天完成10个可变阻力液压训练站的两（第1周和第2周）或三（第3 - 6周）组循环训练，运动与休息比例为1:2。运动角速度保持在约3.1弧度·秒⁻¹。训练后，最大摄氧量从4.32升·分钟⁻¹增加到4.68升·分钟⁻¹（p < 0.01）。最大每搏输出量从120毫升增加到129毫升（p < 0.05），对绝对次最大运动负荷的心率反应从153次·分钟⁻¹降至146次·分钟⁻¹（p < 0.05）。此外，在力竭运动恢复过程中观察到血乳酸清除增强（p < 0.01）。对照组未观察到变化。这些结果表明，高速循环抗阻训练可能会使有氧和心血管功能产生积极改变。
