A preliminary study of transitions between the walk and trot in dressage horses.

This research was conducted to investigate how dressage horses transition between walking and trotting. The study found that advanced training in dressage horses is linked to smoother transitions without intermediate steps.

Study Objective and Hypothesis

• The primary aim of this research was to determine the sequence in which horses’ limbs support their body weight during transitions from walking to trotting and vice versa, while riding under saddle.
• The researchers hypothesized that there would be no relationship between the sequence of limb support during the transitions and the level of training the horse had received. This assumption is referred to as the null hypothesis.

Study Design and Methodology

• Sixteen dressage horses, with training ranging from novice to the highest level in the sport (FEI Grand Prix), were videotaped performing an average of nine transitions each from walk to trot and from trot to walk.
• The team used 30-Hz videotapes, observed in slow motion, to analyze the steps taken by the horses during the transition between walking and trotting.
• Horses’ transitions were then categorized into two types: type 1 (with no intermediate steps between the walk and trot sequences) and type 2 (with additional intermediate steps).

Results and Findings

• The findings revealed that the level of training correlates positively with the percentage of type 1 transitions. Higher training level resulted in more type 1 transitions for both walk-to-trot (p < or = 0.05) and trot-to-walk (p < or = 0.01) transitions, which contradicts the original null hypothesis.
• The research also determined that there is no significant preference for horses to start or finish the trot on the left or right diagonal limb. This conclusion was generated by using the binomial test for individual horses and the Wilcoxon signed-ranks test for the group as a whole.

Conclusion

• The research concluded that higher levels of dressage training could potentially be linked to smoother transitions between walking and trotting, with fewer intermediate steps.
• Although it was not a part of the original research question, the study also discovered that horses don’t show any strong preference for shifting weight to either the left or right diagonal limb during these transitions.
