Temporal changes in the trot between the first and third horse inspections at a CCI*** 3-day event.

The research investigates the changes in the way horses trot during a CCI*** 3-day event, noting variations between the first and third horse inspection. The analysis concluded that horses tend to trot with a higher velocity, shorter stride length and duration during the third inspection, despite maintaining a consistent temporal relationship.

Methodology

• The researchers used kinematic parameters, measurements that describe motion, gathered from horses participating in a CCI*** 3-day event.
• 16 horses were filmed using a panning lateral S-VHS video camera operating at 50 Hz during the first and third horse inspections, giving a repeated sample.
• Spatial measurements were taken during both inspections, providing an average stride rate for both stages.
• Data collection focused primarily on periods when the horses were accelerating and achieving constant velocity within the calibration zone.

Key Findings

• The researchers noted that the horses trotted faster during the third inspection with a mean velocity of 0.26 +/- 0.05 m/s, a statistically significant finding (P < 0.001).
• During the same inspection, the horses trotted with a shorter stride length (0.193 +/- 0.03 m) and stride duration (31 +/- 42 m/s), both being statistically significant (P < 0.001).
• Another discovery was the decrease in retraction percentage for both the forelimbs and the hindlimbs during the third inspection, a substantially important finding given the statistical significance (P < 0.001) in both cases.
• However, this study found no significant difference when measuring other temporal parameters as a percentage of the stride between the two inspections.

Conclusion

• The article suggests that despite the apparent changes in stride length and duration, the event horses maintain a consistent temporal relationship during trotting in the course of the third horse inspection.
• This information may help in understanding horse behavior during competitions and could be crucial for training and performance improvement strategies in the future.
