Training devices of muscle strength for persons with deteriorated physical fitness simulating muscular viscoelastic properties

肌肉具有动态特性，可以改变粘弹性以响应施加的力。研制了一种模拟肌肉粘弹性特性的机械驱动器。利用驱动器产生外弹性载荷进行跟踪实验，估计了微体的弹性特性。利用小波变换分析了跟踪误差角。根据频率趋势和肌肉动力学模型估计肌肉弹性特性。肌肉动力学模型表明，肌肉弹性常数与生理实验中确定的值相似。然后，对作动器进行改进，使其产生等粘载荷。比较了等张收缩、等速收缩和等粘收缩时Ne肌的力学性能。结果表明，等粘收缩法是一种安全有效的训练方法。

The muscles have dynamic properties changing the viscoelasticity in response to an exerted force. A mechanical actuator simulating muscular viscoelastic properties was developed. A tracking experiment was conducted using the actuator generating an external elastic load to estimate museular elastic properties. ne tracking error angles were analyzed by the wavelet transform. The muscular elastic properties were estimated from the frequency trends and the musclodynamic model. The musclodynamic model indicated the muscular elastic constant similar to the value determined in the physiological experiment. Next, the actuator was modified lo produce isoviscous load. ne muscle mechanical performance during isotonic, isokinetic and isoviscous contraction was compared. It was found that the isoviscous contraction is a useful and safe way for training in disabled patients and aged people.
