Simulation of Rotational Jumping Motions Around the Horizontal and Sagittal Axes Using a Human Model

Abstract

In this study, a whole-body motion control simulator, originally developed for humanoid robots, was applied to the analysis of human motion. A simulation of whole-body motion of a human model was implemented, focusing on rotational jumping motions around the horizontal and sagittal axes. The validity of the simulation was confirmed by comparing the motion data with human motion measurement data from prior studies in the fields of ergonomics and sports science. The comparison involved isometric joint torque measured using the make test method from previous studies and vertical ground reaction forces in the z-axis direction obtained from force plates. As the simulation results were of the same order of magnitude as these data, the results were deemed accurate. This simulation serves as a valuable tool for the quantitative evaluation of human motion during rotational jumping motions.
