日常活动减少和紧张经常会导致肌肉过度共同收缩，从而导致运动性能下降和损伤。在这项研究中，我们修改的环境和人体之间的相互作用自由和暂时的，使用环境Kinodynamic干预。我们的目标是在步行过程中减少负荷，这是通过在跑步机上行走来实现的，其中跑步机的加速/减速作为干预。一个前向动力学仿真使用的kinodynamic身体模型被用来设计的干预模式。设计的干预模式实施在一个真实的环境中进行验证，使用一个主题实验，有六个主题。结果表明，当跑步机速度较低时，地面反力的垂直分量下降2.14%，腓肠肌和胫骨前肌的活动下降1.89%和%。因此，我们得出结论，干预减少了步行过程中肌肉长度的变化，抑制了牵张反射，并减少了肌肉活动。这些结果证明了使用非侵入性运动动力学干预来修改人类运动控制系统的可能性，从而在运动和日常生活中实现隐式肌肉缓解（DATSURYOKU），以及防止他们受伤。
Decreased daily activities and tension frequently cause excessive muscle co-contractions implicitly, resulting in decreased performance and injury in sports. In this study, we modify the interaction between the environment and human body freely and temporarily, using environmental kinodynamic intervention. We target the load reduction during walking, which is realized by walking on a treadmill, where the acceleration/deceleration of the treadmill acts as the intervention. A forward dynamics simulation using a kinodynamic body model is used to design the intervention pattern. The designed intervention pattern is implemented in a real environment for verification, using a subject experiment with six subjects. The results demonstrate that the vertical component of the ground reaction force decreases by 2.14% and gastrocnemius and tibialis anterior activities decrease by 1.89% and% when the treadmill speed is low at heel contact and accelerates gradually. Hence, we conclude that the intervention decreases the change in the muscle length during walking, suppresses the stretch reflex, and reduces muscle activity. These results demonstrate the possibility to modify human motor control systems using non-invasive kinodynamic interventions, thereby realizing implicit muscle relief (DATSURYOKU) in sports and daily life, as well as to prevent their injuries.
