Six subjects performed rapid self-terminated elbow movements under different mechanical conditions prior to, and 5 weeks after an elbow extensor strengthening programme. Despite the large difference in the strengths of elbow flexors and extensors, the pretest did not demonstrate significant differences between the movement time of flexion and extension movements performed under the same mechanical conditions. The results obtained in the posttest demonstrated a decrease in movement time (i.e. an increase in movement speed) in both elbow flexion and extension movements under some mechanical conditions. In addition, flexion movements demonstrated a relative increase in the acceleration time (acceleration time as a proportion of the movement time). It was concluded that the strength of both the agonist and antagonist muscles was important for the performance of rapid movements. Stronger agonists could increase the acceleration of the limb being moved, while stronger antagonists could facilitate the arrest of the limb movement in a shorter time, providing a longer time for acceleration.
六名受试者在进行伸肘强化训练计划之前以及训练五周后，于不同力学条件下进行了快速自我终止的肘部运动。尽管肘部屈肌和伸肌力量存在很大差异，但预测试并未显示在相同力学条件下进行的屈伸运动的运动时间之间存在显著差异。后测试获得的结果表明，在某些力学条件下，肘部屈伸运动的运动时间均有所减少（即运动速度增加）。此外，屈曲运动的加速时间（加速时间占运动时间的比例）相对增加。得出的结论是，主动肌和拮抗肌的力量对于快速运动的表现都很重要。更强壮的主动肌可以增加被移动肢体的加速度，而更强壮的拮抗肌可以在更短的时间内促进肢体运动的停止，从而为加速提供更长的时间。
