Upper limb movement is vital in daily life. A biomechanical simulation of the forearm with consideration physiological characteristics muscles instrumental gaining deeper insights into upper motion mechanisms. In this study, we established a finite element model forearm, including radius, biceps brachii, and tendons. We simulated resulting from contraction brachii by using Hill-type transversely isotropic hyperelastic muscle model. adjusted velocity found that slower facilitated flexion. Then, changed percentage fast-twitch fibers, maximum strength, neural excitation values to investigate flexion elderly individuals. Our results indicated reduced fiber percentage, contributed decline capability Additionally, there threshold for excitation, below which, sharply declines. aids understanding role identifying causes disorders, which able provide guidance enhancing performance.
