To interpret the movement strategies employed in locomotion, it is necessary to understand the source of metabolic cost. Muscles must consume metabolic energy to do work, but also must consume energy to generate force. The energy lost during steady l

Constrained optimization of metabolic cost in human hopping

Autor: Anne K. Gutmann, John E. A. Bertram

Publikováno v: Experimental Physiology. 98:1178-1189

New Findings • What is the central question of this study?This study evaluates whether constrained optimization of metabolic cost (minimization of metabolic cost within the limitations imposed by constraints) predicts movement selection during vert

The apparently contradictory energetics of hopping and running: the counter-intuitive effect of constraints resolves the paradox

Autor: Anne K. Gutmann, John E. A. Bertram

Publikováno v: Journal of Experimental Biology.

Metabolic rate appears to increase with the rate of force application for running. Leg function during ground contact is similar in hopping and running, so one might expect that this relationship would hold for hopping as well. Surprisingly, metaboli

Motions of the running horse and cheetah revisited: fundamental mechanics of the transverse and rotary gallop

Autor: John E. A. Bertram, Anne K. Gutmann

Publikováno v: Journal of The Royal Society Interface. 6:549-559

Mammals use two distinct gallops referred to as the transverse (where landing and take-off are contralateral) and rotary (where landing and take-off are ipsilateral). These two gallops are used by a variety of mammals, but the transverse gallop is ep

The dynamic limits of hop height: Biological actuator capabilities and mechanical requirements of task produce incongruity between one- and two-legged performance

Autor: Anne K. Gutmann, John Ea Bertram

Publikováno v: Proceedings of the Institution of Mechanical Engineers. Part H, Journal of engineering in medicine. 230(3)

The maximum hop height attainable for a given hop frequency falls well below the theoretical limit dictated by gravity, h = g/8 f2. However, maximum hop height is proportional to 1/ f2, suggesting that ground reaction force and, hence, force producti

Exploring the Role of the Tail in Bipedal Hopping through Computational Evolution

Autor: Anne K. Gutmann, Philip K. McKinley, Jared M. Moore, Craig P. McGowan

Publikováno v: ECAL

Bipedal hopping has evolved as a mode of terrestrial locomotion in relatively few mammalian species. Despite large differences in body size, habitat use, and having evolved independently, all species that use bipedal hopping have remarkably similar l

Constrained optimization of metabolic cost in human hopping

Autor: Anne K, Gutmann, John E A, Bertram

Publikováno v: Experimental physiology. 98(7)

Constrained optimization of metabolic cost/distance travelled largely predicts the gait parameters selected by humans during walking and running. This study evaluates whether this is also the case for human hopping. Hop frequency (f), height (h) and

Constrained optimization in human running

Autor: John E. A. Bertram, Anne K. Gutmann, Brian Jacobi, Michael T. Butcher

Publikováno v: The Journal of experimental biology. 209(Pt 4)

SUMMARYWalking humans spontaneously select different speed, frequency and step length combinations, depending on which of these three parameters is specified. This behavior can be explained by constrained optimization of cost of transport (metabolic

Collision-based mechanics of bipedal hopping

Autor: Anne K. Gutmann, David Lee, Craig P. McGowan

Publikováno v: Biology Letters. 9:20130418

The muscle work required to sustain steady-speed locomotion depends largely upon the mechanical energy needed to redirect the centre of mass and the degree to which this energy can be stored and returned elastically. Previous studies have found that
