Summary
The research article focuses on how the choice of horseshoes and surfaces impacts the biomechanics of horse-jockey pairs during galloping by observing changes in their centre of mass (COM) displacements. The three variables considered are different types of horseshoes (aluminium, barefoot, GluShu, and steel), surfaces (turf or artificial track), and the combined effect of both.
Research Methodology
- The study enlisted thirteen retired racehorses and two jockeys from the British Racing School.
- Centre of mass (COM) was monitored using iPhones fitted with a specific iOS application, SensorLog, attached to a specific area of both the horse (girth) and the jockey (kidney-belt). The app gathered tri-axial acceleration data.
- The different shoe-surface combinations were introduced in a random manner, whereas the horse-jockey pairings stayed constant.
- The tri-axial acceleration data collected from the gallop runs were processed using bandpass Butterworth filters and integrated for displacement.
- The peak displacement in all directions was evaluated in positive and negative along three axes – cranio-caudal (forwards and backwards), medio-lateral (right and left), and dorso-ventral (up and down).
- The effect of surfaces, shoe types, and their interactions, on observed displacement patterns were statistically evaluated through linear mixed-models, considering day, run and horse-jockey pairs as random factors.
Results of the Study
- Surface type significantly affected COM displacements in all directions for both horse and jockey, except for the forward direction in jockeys.
- Considerably higher differences were registered in the dorso-ventral or vertical axis setup. The displacement was higher downwards by an additional 5.7 mm and 2.5 mm for the horse and jockey, respectively, on the artificial surface.
- Different shoeing conditions notably impacted all displacement parameters, with maximum differences seen vertically.
- Shoe-surface interactions also affected the displacement parameters, except for medio-lateral minima for horses and cranio-caudal minima for jockeys.
These results indicate that arrangements related to hoof-surface interface can have substantial effects on horse and jockey displacements. The heightened vertical displacements on artificial track may be due to an increased sink of hooves on impact, combined with augmented push-off during the propulsive phase. Variations associated with shoe-types could result in compensatory COM displacements. The study also encourages further research to link COM displacements to hoof kinematics, and to determine an optimum configuration for performance enhancement and injury minimization.
