EMG-RTs of biceps and triceps brachii muscles were measured in 3 different tasks: isolated motions, flexion or extension of either forearm; bilateral symmetrical motions, flexion or extension of both forearms; bilateral opposite motions, flexion of a forearm and extension of the other. EMG-RTs of opposite motions were slower than those of isolated and symmetrical motions, EMG-RTs of symmetrical motions were nearly equivalent to those of isolated motions. Simplicity and complexity of simultaneous motions are discussed.
在3种不同任务中测量肱二头肌和肱三头肌的肌电图反应时间（EMG-RTs）：孤立动作，即任一前臂的屈曲或伸展；双侧对称动作，即双侧前臂的屈曲或伸展；双侧相反动作，即一侧前臂屈曲而另一侧前臂伸展。相反动作的EMG-RTs比孤立动作和对称动作的要慢，对称动作的EMG-RTs几乎等同于孤立动作的。同时讨论了同步动作的简单性和复杂性。
