It has been found that there were almost piece linear functions "moment of control forces-joint angle" during non-rhythmic human habitual movements whose basis was flexion or extension of elbow. It means that non-linear effects due to direct effects of time, muscle length and contraction velocity in net muscle force were eliminated by neural regulation. One of the main regulation tasks seems to achieve invariability of energy expenditure in regard to motion trajectories. So, the linearizing of control forces indicates uniparametric nature of control process. It was shown that in addition to linear dependences there were also non-linear functions "moment of control force-joint angle". This suggests that on the whole the control process is characterized by more than one parameter.
已经发现，在以肘部屈伸为基础的非节律性人类习惯性运动中，存在几乎呈线性的“控制力矩 - 关节角度”函数。这意味着，通过神经调节消除了时间、肌肉长度和收缩速度对净肌力的直接影响所产生的非线性效应。主要调节任务之一似乎是实现运动轨迹能量消耗的不变性。因此，控制力的线性化表明控制过程具有单参数性质。结果表明，除了线性关系外，还存在“控制力矩 - 关节角度”的非线性函数。这表明，总体而言，控制过程具有不止一个参数的特征。
