The capability of muscle to produce mechanical work under periodic motions has been traditionally estimated using the workloop technique. We extend this method by allowing a pair of antagonist muscles to interact against a common load with non-zero admittance. We present an experimental approach to measuring the work done by a two-muscle system and show preliminary data. A complimentary problem is to maximize the work produced by the muscle pair in this setting. We formulate this problem in an optimal control framework. We derive conditions for the optimal activation of muscles to produce the maximum work, and show computed solutions.
传统上,肌肉在周期性运动下产生机械功的能力是使用功循环技术来估算的。我们通过允许一对拮抗肌以非零导纳对抗共同负载来扩展此方法。我们提出了一种测量双肌肉系统所做功的实验方法,并展示了初步数据。一个补充性问题是在此设置下使肌肉对产生的功最大化。我们在最优控制框架中阐述了这个问题。我们推导了肌肉最优激活以产生最大功的条件,并展示了计算结果。
