On the centre of mass motion in human walking
WebA model of muscle-tendon function in human walking, IEEE International Conference on Robotics and Automation (ICRA), Kobe, Japan, May 2009. Angular momentum in human walking. Angular momentum is a conserved physical quantity for isolated systems where no external moments act about a bodyʼs center of mass (CM). WebVirtual stance-limb compression (i.e. reduction in the distance between the point of foot-ground contact and the center of mass during the first half of the stance phase) was …

WebThe movement of the center of mass (COM) during human walking has been hypothesized to follow a sinusoidal pattern in the vertical and mediolateral directions. … WebCenter of mass (CoM) oscillations were documented for 81 bipedal walking strides of three chimpanzees. Full-stride ground reaction forces were recorded as well as kinematic data to synchronize force to gait events and to determine speed. Despite being a bent-hip, bent-knee (BHBK) gait, chimpanzee walking uses pendulum-like motion with vertical ...
