ABSTRACT

　This study proposed a new model of muscle fatigue and recovery considering the roleof slow and fast twitch muscles. This model can estimate the variation of the musclefatigue since this model considers the properties of muscle fatigue and recovery, whichthe previous model does not consider. The feature of this study is to estimate not onlythe variation of muscle fatigue under maximum voluntary construction（ MVC） but alsothe endurance time under any constant force. In order to validate the proposed model,a case study was conducted. The parameters, which depend on the human property,were determined by the measured variation under output of MVC. The endurance timeunder any constant force was also measured by the case study and the measured timewas compared with the time estimated by the proposed model. According to the casestudy, the estimated time had a good agreement with the measured one. Therefore,the proposed model can be applied to the condition of the low output force, which theprevious model cannot be applied to.
