Quantification of the Effect of Saddle Fitting on Rider-Horse Biomechanics Using Inertial Measurement Units

Area of Science:

• Equine biomechanics
• Sports science
• Wearable sensor technology

Background:

• Saddle adaptability is crucial for rider-horse comfort and performance.
• Current dynamic saddle fitting evaluation methods are limited.
• Understanding saddle influence on equine locomotion is vital.

Purpose of the Study:

• To propose a novel method for quantifying saddle adaptation in dynamic rider-horse interactions.
• To assess the impact of subtle saddle modifications on equine and rider biomechanics.
• To establish a quantifiable approach for optimizing saddle fit.

Main Methods:

• Utilized seven inertial sensors on eight rider-horse pairs.
• Measured horse limb range of motion, stride duration, and rider pelvic motion.
• Analyzed rider-horse interaction and temporal movement synchronization.

Main Results:

• Small saddle modifications demonstrably altered rider-horse biomechanics.
• Specific saddle configurations restricted limb movement and altered stride characteristics.
• Saddle changes influenced rider pelvic motion and rider-horse temporal synchronization.

Conclusions:

• Subtle saddle variations significantly affect equine locomotion and rider-horse synchronization.
• Inertial sensor technology offers a viable method for dynamic saddle fit quantification.
• This approach can optimize saddle adaptability and improve equestrian performance and comfort.
