A longitudinal study of back dimension changes over 1 year in sports horses.

This research studied the changes in the back dimensions of sports horses over the course of a year, considering factors such as the horse’s condition, saddle fit, type/level of work done by the horse, and seasonal changes. The findings indicate that back dimensions do considerably change over time and these changes are notably influenced by certain factors such as the presence of gait abnormalities and back asymmetry, saddle fit, work intensity, season, and weight of the horse.

Study Design and Methodology

• The study design was a longitudinal assessment conducted over a year, with measurements done every two months.
• Using stratified random sampling within a convenience sample of 104 sports horses that were being regularly worked, measurements of the thoracolumbar area (part of the horse’s back) were collected at predetermined sites.
• The study set out to understand the variations in the back dimensions over time and identify the contributing factors such as horse condition, saddle and rider’s influence, work type, and saddle management.

Data Collection

• Alongside the back measurements, data related to changes in the horse’s weight, type and amount of work, and alterations in saddle management were also recorded.
• However, complete data was available only for 63 out of the 104 initial participants. These consisted of horses used for dressage, showjumping, eventing, and general-purpose, across different age groups.

Findings and Analysis

• The data revealed that there were substantial variations in back dimensions of the horses over the course of a year.
• The presence of gait abnormalities and back asymmetry in horses at the initial examination were significantly associated with the changes noticed in back dimensions, with a negative effect.
• Changes such as improved saddle fit, increased or similar work intensity, seasonal changes (summer versus winter), and increase in the horse’s weight were considered significant for positive changes in back dimensions.

Conclusion

• The study concluded that changes in the back dimensions of sports horses can be quantified and do occur all through the year.
• It emphasized the importance of reassessing the professional fit of the saddle several times a year, especially if there have been changes in the horse’s work intensity.
