Dynamic model of muscle fatigue and recovery considering the roles of slow-twitch and fast-twitch muscles (Validation with a pulling motion

Dynamical model of muscle fatigue and recovery considering the behavior of slow- and fast-twitch muscles and the roles of antagonistic muscles

“…In the present chapter, the musculoskeletal model considering the role of antagonistic muscle pairs proposed by Oshima et al (1999) is first explained. The muscle fatigue and recovery model considering the different behaviors of ST and FT fibers previously proposed by our research group (Miura et al, 2019) is then explained in section 2.2. Finally, the method of predicting the degree of fatigue of each muscle in the arm proposed in the present study is described in section 2.3.…”

“…Our research group proposed the model shown in Fig. 3 for the prediction of muscle fatigue and recovery considering the roles of ST and FT fibers (Miura et al, 2019). As before, the muscle is considered to consist of M0 total motor units.…”

“…The output force measured in the experiment described in section 3.3 was compared with the output force predicted using the proposed model. Furthermore, the output force was predicted with the previous muscle fatigue model without considering antagonistic muscles (Miura et al, 2019). The measured output force was compared with the output forces predicted by the proposed and previous models, as shown in Fig.…”

“…ST fibers are characterized by fatigue resistance and a low rate of contraction, whereas FT fibers show fatigable and rapid contraction. In our previous study, we proposed a model considering the roles of ST and FT fibers to evaluate muscle fatigue and recovery (Miura et al, 2019).…”
