Comparative anatomy and muscle architecture of selected hind limb muscles in the Quarter Horse and Arab
Journal Article
Crook, T. C., Cruickshank, S. E., McGowan, C. M., Stubbs, N., Wakeling, J. M., Wilson, A. M., & Payne, R. C. Comparative anatomy and muscle architecture of selected hind limb muscles in the Quarter Horse and Arab. Journal of Anatomy, 212(2), 144-152. https://doi.org/10.1111/j.1469-7580.2007.00848.x

The Quarter Horse (bred for acceleration) and the Arab (bred for endurance) are situated at either end of the equine athletic spectrum. Studies into the form and function of the leg muscles in human sprint and endurance runners have demonstrated that...

Optimal muscle fascicle length and tendon stiffness for maximising gastrocnemius efficiency during human walking and running
Journal Article
Lichtwark, G. A., & Wilson, A. M. Optimal muscle fascicle length and tendon stiffness for maximising gastrocnemius efficiency during human walking and running. Journal of Theoretical Biology, 252(4), 662-673. https://doi.org/10.1016/j.jtbi.2008.01.018

Muscles generate force to resist gravitational and inertial forces and/or to undertake work, e.g. on the centre of mass. A trade-off in muscle architecture exists in muscles that do both; the fibres should be as short as possible to minimise activati...

High-speed gallop locomotion in the Thoroughbred racehorse. II. The effect of incline on centre of mass movement and mechanical energy fluctuation
Journal Article
Parsons, K. J., Pfau, T., Ferrari, M., & Wilson, A. M. High-speed gallop locomotion in the Thoroughbred racehorse. II. The effect of incline on centre of mass movement and mechanical energy fluctuation. Journal of Experimental Biology, 211(6), 945-956. https://doi.org/10.1242/jeb.006692

During locomotion on an incline, mechanical work is performed to move an animal up the slope and increase the potential energy ( PE) of the trunk and hence the centre of mass ( CoM). Thus, at a given speed the total net mechanical work increases with... Read More about High-speed gallop locomotion in the Thoroughbred racehorse. II. The effect of incline on centre of mass movement and mechanical energy fluctuation.

High-speed gallop locomotion in the Thoroughbred racehorse. I. The effect of incline on stride parameters
Journal Article
Parsons, K. J., Pfau, T., & Wilson, A. M. High-speed gallop locomotion in the Thoroughbred racehorse. I. The effect of incline on stride parameters. Journal of Experimental Biology, 211(6), 935-944. https://doi.org/10.1242/Jeb.006650

During locomotion up an incline, power is required to elevate the centre of mass. This is provided when the animal's limbs are in contact with the ground. Measurements of stride timing variables from multiple limbs during high speed, over-ground loco... Read More about High-speed gallop locomotion in the Thoroughbred racehorse. I. The effect of incline on stride parameters.

A hidden Markov model-based stride segmentation technique applied to equine inertial sensor trunk movement data
Journal Article
Pfau, T., Ferrari, M., Parsons, K. J., & Wilson, A. M. A hidden Markov model-based stride segmentation technique applied to equine inertial sensor trunk movement data. Journal of Biomechanics, 41(1), 216-220. https://doi.org/10.1016/j.jbiomech.2007.08.004

Inertial sensors are now sufficiently small and lightweight to be used for the collection of large datasets of both humans and animals. However, processing of these large datasets requires a certain degree of automation to achieve realistic workloads...

The mechanism for efficacy of eccentric loading in Achilles tendon injury; an in vivo study in humans
Journal Article
Rees, J. D., Lichtwark, G. A., Wolman, R. L., & Wilson, A. M. The mechanism for efficacy of eccentric loading in Achilles tendon injury; an in vivo study in humans. https://doi.org/10.1093/rheumatology/ken262

Objective. Degenerative disorders of tendons present an enormous clinical challenge. They are extremely common, prone to recur and existing medical and surgical treatments are generally unsatisfactory. Recently eccentric, but not concentric, exercise...

Possible causes of divergent population trends in sympatric African herbivores
Journal Article
Bennitt, E., Hubel, T. Y., Bartlam-Brooks, H. L. A., & Wilson, A. M. (in press). Possible causes of divergent population trends in sympatric African herbivores. PLoS ONE, 14(3), e0213720. https://doi.org/10.1371/journal.pone.0213720

Sympatric herbivores experience similar environmental conditions but can vary in their population trends. Identifying factors causing these differences could assist conservation efforts aimed at maintaining fully functional ecosystems. From 1996–2013...

External mechanical work in the galloping racehorse
Journal Article
Self Davies, Z. T., Spence, A. J., & Wilson, A. M. (in press). External mechanical work in the galloping racehorse. Biology Letters, 1, https://doi.org/10.1098/rsbl.2018.0709

Horse locomotion is remarkably economical. Here, we measure external mechanical work of the galloping horse and relate it to published measurements of metabolic cost. Seven Thoroughbred horses were galloped (ridden) over force plates, under a racing... Read More about External mechanical work in the galloping racehorse.
