Saddle pressure patterns of three different training saddles (normal tree, flexible tree, treeless) in Thoroughbred racehorses at trot and gallop.

This research article investigates the influence of different training saddles on saddle pressure patterns in Thoroughbred racehorses. The study found that the type of saddle tree does not significantly affect pressure in the back third of the saddle during a gallop, but high peak pressures at a trot in all saddle types may limit the horse’s back activity.

Objectives of the Research

• The researchers aim to understand the impact of different types of training saddles on pressure patterns in racehorses.
• The focus was on three types of saddles: one with a normal tree (S(A)), a treeless one (S(B)), and one with a flexible tree (S(C)).
• The objective was to test the common assumption that S(A) restricts the movement of the back, specifically the lower thoracic region, during a gallop. This could potentially lead to higher pressures in the hind part of the saddle at different gaits.

Methods of the Research

• The saddle pressure was measured in eight Thoroughbred racehorses during various gaits (trot, canter, and gallop) on a training track.
• Each horse performed the protocol with each different saddle type.
• The saddle pressure was analyzed by dividing the pressure picture into thirds: front (TD(front)), middle (TD(mid)), and back (TD(hind)).
• The stride-mean loaded areas, forces, and mean and peak pressures were determined for each horse and each saddle type at each gait.

Results of the Research

• At a canter and gallop, all three saddle types were primarily loaded in the front area (over 80% of the rider’s weight), with gradually decreasing pressure towards the middle and the hind area (less than 3%).
• The pressure decreases were least pronounced in the flexible tree saddle (S(C)).
• At a trot, the load was shifted towards the middle and the hind area (10-15% each).
• High peak pressures occurred in the front area at a canter and gallop, and in the hind area at a trot.

Conclusion of the Research

• The study concluded that the type of saddle tree did not significantly influence the pressure picture of the back third of the saddle during a gallop.
• However, the high peak pressures at a trot in all saddle types could limit the horse’s back activity.
• This has particular importance as the trot is an integral part of a horse’s daily work and such hindrance could potentially affect the horse’s training success.
