| Research Abstract |
Development of digital human models which perform muscle force estimation and muscle fatigue evaluation for the work environment design is an objective of this study. A musculoskeletal model considering the functions of the antagonistic and the biarticular muscles was developed. Vertical jump was analyzed to estimate muscle forces, and estimated results had a good agreement with the measured surface electromyograms (EMGs) of muscles. Additionally, a muscular fatigue model to evaluate muscle fatigue progress under several muscular force patterns was developed. The evaluated muscle fatigue progress had a good agreement with the experimental results.
