Evaluation of consistency of jumping technique in horses between the ages of 6 months and 4 years.

This research sought to understand the consistency in jumping technique in horses by comparing the techniques of horses when they were 6 months old and 4 years old. The findings showed some characteristics of the jumping techniques observable in 4 year olds could already be detected when the horses were just foals.

Methods

• The study group comprised of 12 Dutch Warmblood horses.
• Kinematics were recorded for these horses during “free jumps” when they were both 6 months old (with no jumping experience) and 4 years old (where they’d begun their training phase to become show jumpers).
• The average height of the horses at these two ages was also recorded as 1.40 +/- 0.04 m and 1.70 +/- 0.05 m respectively.

Results

• The study found strong correlations between values from the horses when they were 6 months old and when they were 4 years old for various measures tied to jumping ability and technique.
• These measures include:
  • Peak vertical acceleration generated by the hind limbs
  • Peak rate of change of effective energy generated by the hind limbs
  • Vertical velocity at takeoff
  • Vertical displacement of the center of gravity during the airborne phase
  • Duration of the airborne phase
• The correlation coefficients ranged from a high of 0.91, signifying a very strong correlation, to a lower but still significant 0.65.

Conclusions

• The findings revealed that even though there are several anatomical and behavioural transformations that occur as horses grow, some aspects of the jumping technique observed in their adult (four-year-old) stage can be detected in their initial jumping attempts during their foal (six-month old) stage.

This study can help better understand the nuances of equine biomechanics and potentially inform training practices for strength and performance enhancement in horses from an early age.
