Design and demonstration of a dynamometric horseshoe for measuring ground reaction loads of horses during racing conditions.

This research article is focused on the creation and testing of a specially designed horseshoe which can measure the loads exerted by a horse’s hoof on the ground during various activities common in racing conditions, aiming to assess factors like track surface and their influence on musculoskeletal injuries in racehorses.

Design and Construction of the Horseshoe

• The research team developed a dynamometric horseshoe. This unique equipment could measure the complete ground reaction loading during racing conditions. The horseshoe was created using electrical resistance strain gages.
• The design aimed to imitate the load transfer surface of the hoof. The surface in contact with the ground resembled the hoof’s solar surface.

Assessment and Calibration

• Post-creation, the researchers carried out a static calibration to establish the measurement accuracy. They found that the root mean squared errors (RMSE) were 3% of full scale for the force component normal to the hoof and 9% for force components in the hoof’s plane.
• The dynamic calibration discovered that the natural frequency with a typical horse’s full weight was 1744 Hz.

Collection of Sample Data

• The team collected example data during four different horse gaits: walking, trotting, cantering, and galloping. The walking data was obtained on a ground surface while the other gaits were tested on a treadmill.
• The instrument successfully measured the complete ground reaction load during all four gaits, illustrating its practical usage.

Conclusion

• The research concluded that the dynamometric horseshoe is a useful tool for studying the factors that influence the ground reaction loads during racing conditions. These factors can include the racing track’s surface, which could potentially improve the understanding and prevention of musculoskeletal injuries in racehorses.
