In this study we compared the influence that the order of the performance of different velocity exercise progressions has on average muscle power and total work production during a velocity spectrum isokinetic training session. Twenty-two college students were assigned randomly to four exercise trials, each containing an isokinetic exercise training session involving dominant knee extensors and flexors. Each exercise trial consisted of two sets of ten repetitions at speeds of 30 degrees , 90 degrees , 150 degrees , and 210 degrees /sec. The pretest, posttest, and experimental session muscle function measurements were assessed. Selected measurements of average power (joules/sec) and total work (joules) were used to make comparisons between the protocols. There was no training effect (change in peak torque) during the study for either extension or flexion at any of the four speeds. Total work was similar across the four protocols. There was a difference in average power for both extension and flexion among the protocols. We conclude that when performing velocity spectrum type training, performing faster speed sets early in the exercise session will produce a greater average power.
在这项研究中，我们比较了在进行速度谱等速训练时，不同速度练习进展顺序对平均肌肉力量和总功产生的影响。22 名大学生被随机分配到四个运动试验中，每个试验都包含一次涉及主导膝关节伸肌和屈肌的等速运动训练。每个运动试验由两组 10 次重复组成，速度分别为 30 度、90 度、150 度和 210 度/秒。在预测试、后测试和实验会话中评估肌肉功能测量值。选择平均功率（焦耳/秒）和总功（焦耳）的测量值来比较不同方案之间的差异。在研究过程中，四个速度中任何一个速度的伸肌和屈肌都没有训练效果（峰值扭矩的变化）。四个方案的总功相似。在协议之间，伸展和弯曲的平均功率存在差异。我们得出的结论是，在进行速度谱类型的训练时，在运动训练早期进行更快的速度训练会产生更大的平均功率。
