Design and Development of a Model to Simulate 0-G Treadmill Running Using the European Space Agency's Subject Loading System

DESIGN The theoretical basis for the Running Model was based on a simple spring-mass model. The dynamic properties of the spring-mass model express theoretical vertical GRF (GRFv) and shear GRF in the posterior-anterior direction (GRFsh) during running gait.[1,2] ADAMs VIEW software was used to build the model, which has a pelvis, thigh segment, shank segment, and a spring foot (see Figure 1).the model’s movement simulates the joint kinematics of a human running at Earth gravity with the aim of generating GRF data.
