To determine the effects of isokinetic resistance training of the quadriceps, 25 male volunteers were randomly assigned to five training groups: Concentric Slow (CS), Concentric Fast (CF), Concentric-Eccentric Slow (MS), Concentric-Eccentric Fast (MF), and Control (C). In training, subjects performed 20 contractions of each quadriceps using either 60 degrees/sec or 180 degrees/sec, for both sides, five days per week for 12 weeks. Testing consisted of measurement of peak torque, at intervals of 60 degrees/sec across a spectrum of velocities ranging from plus to minus 240 degrees/sec, at 0, 4, 8, and 12 weeks. Repeated MANOVA using planned comparisons showed that all trained subjects made significant peak torque gains (p < .05), but that the gains made by MS and MF were greater. These findings suggest that the addition of an eccentric training component to a concentric isokinetic training program may allow greater peak torque gains regardless of the velocity.
为了确定股四头肌等速阻力训练的效果，25名男性志愿者被随机分为五个训练组：向心慢速组（CS）、向心快速组（CF）、向心-离心慢速组（MS）、向心-离心快速组（MF）和对照组（C）。在训练中，受试者双侧股四头肌均以60度/秒或180度/秒的速度进行20次收缩，每周训练五天，共训练12周。测试包括在0、4、8和12周时，以正负240度/秒的速度范围，每隔60度/秒测量一次峰值扭矩。使用计划比较的重复多变量方差分析表明，所有接受训练的受试者峰值扭矩均有显著增加（p < 0.05），但MS组和MF组的增加幅度更大。这些发现表明，在向心等速训练计划中增加离心训练成分，可能会使峰值扭矩有更大的增加，而与速度无关。
