| Research Abstract |
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.
