Minimizing center of mass vertical movement increases metabolic cost in walking.
A human walker vaults up and over each stance limb like an inverted pendulum. This similarity suggests that the vertical motion of a walker's center of mass reduces metabolic cost by providing a mechanism for pendulum-like mechanical energy exchange. Alternatively, some researchers have hypothesized that minimizing vertical movements of the center of mass during walking minimizes the metabolic ...
متن کاملMetabolic and mechanical energy costs of reducing vertical center of mass movement during gait.
OBJECTIVES To test the hypothesis that reducing vertical center of mass (COM) displacement will lower the metabolic cost of human walking. To examine changes in joint work associated with increasing and decreasing vertical COM movement during gait. DESIGN Randomized repeated measures. SETTING Human Neuromechanics Laboratory, University of Michigan. PARTICIPANTS Able-bodied subjects (N=10)...
متن کاملCenter of mass movement and energy transfer during walking in children with cerebral palsy.
OBJECTIVE To gain insight into the mechanical inefficiencies of gait patterns used by children with spastic diplegia by analysis of center of mass (COM) movement and energy recovery. DESIGN Prospective study using between-group measures to analyze differences between children with cerebral palsy (CP) and age-matched controls without CP. SETTING Assessments were performed in a gait laborator...
متن کاملThe effect of walking speed on center of mass displacement.
The movement of the center of mass (COM) during human walking has been hypothesized to follow a sinusoidal pattern in the vertical and mediolateral directions. The vertical COM displacement has been shown to increase with velocity, but little is known about the mediolateral movement of the COM. In our evaluation of the mediolateral COM displacement at several walking speeds, 10 normal subjects ...
متن کاملCenter of mass mechanics of chimpanzee bipedal walking.
Center 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 oscillations of the CoM that are similar in pattern...
