An extension to the collisional model of the energetic cost of support qualitatively explains trotting and the trot–canter transition
Journal Article
Usherwood, J. R. (in press). An extension to the collisional model of the energetic cost of support qualitatively explains trotting and the trot–canter transition. https://doi.org/10.1002/jez.2268

The majority of terrestrial mammals adopt distinct, discrete gaits across their speed range. Though there is evidence that walk, trot and gallop may be selected at speeds consistent with minimizing metabolic cost (Hoyt and Taylor, 1981, Nature, 291,...

An instrumented centrifuge for studying mouse locomotion and behaviour under hypergravity
Journal Article
Smith, B. J. H., & Usherwood, J. R. (in press). An instrumented centrifuge for studying mouse locomotion and behaviour under hypergravity. Biology Open, 8, https://doi.org/10.1242/bio.043018

Gravity may influence multiple aspects of legged locomotion, from the periods of limbs moving as pendulums to the muscle forces required to support the body. We present a system for exposing mice to hypergravity using a centrifuge and studying their...

Compass gait mechanics account for top walking speeds in ducks and humans
Journal Article
Usherwood, J. R., Szymanek, K. L., & Daley, M. A. Compass gait mechanics account for top walking speeds in ducks and humans. Journal of Experimental Biology, 211(23), 3744-3749. https://doi.org/10.1242/jeb.023416

The constraints to maximum walking speed and the underlying cause of the walk-run transition remains controversial. However, the motions of the body and legs can be reduced to a few mechanical principles, which, if valid, impose simple physics-based...
