Summary
# Editorial Summary Researchers at the University of Utrecht tracked 25 horses from six months of age through to five years, capturing three-dimensional kinematic data during free jumps as foals and ridden jumps as adults, then stratifying horses post-competition into best (n=7), worst (n=6) and intermediate groups based on puissance performance. Superior jumping technique—characterised by increased elbow flexion shortening the forelimbs and retroflexion of the hindlimbs at clearance—was evident in the best-jumping group at both five years of age and at foal stage, suggesting that efficient limb mechanics are an inherent characteristic rather than an acquired skill. However, substantial individual variation meant that kinematic variables alone from submaximal foal jumps lacked sufficient predictive power for forecasting adult competitive jumping capacity. These findings indicate that whilst elite jumping horses demonstrate consistent mechanical advantages across their lifespan, early movement analysis provides limited utility for culling or selecting young stock for jumping careers, and that other factors—including training, temperament, and accumulated injury history—substantially influence adult performance outcomes.

Practical Takeaways
- •Early kinematic assessment at foal age can identify group-level patterns associated with jumping ability but cannot reliably predict individual horses' future performance
- •Foals showing superior limb mechanics at 6 months (greater elbow flexion, better hind limb control) may have higher jumping potential, but selection based on these traits alone is premature
- •Longitudinal kinematic analysis during growth may be more valuable for understanding performance development than one-time foal assessments
Key Findings
- •Best jumpers (n=7) demonstrated superior limb kinematics at 5 years: increased elbow flexion at forelimb clearance and increased hind limb retroflexion at hind limb clearance compared to worst jumpers (n=6)
- •Superior jumping technique was already detectable at 6 months of age in foals that later became best jumpers
- •Individual prediction of adult jumping capacity from foal-age kinematic data during submaximal jumps was not feasible despite group-level differences
