Ground reaction force patterns of Dutch Warmbloods at the canter.

This study presents data on the force exerted on the ground by various limbs of Dutch Warmblood horses while they are cantering, with the right forelimb leading. It reveals an asymmetry in these forces, which could be vital for evaluating the performance and health of jumping horses.

Objective of the Research

• The primary purpose of this study was to examine the ground reaction force (GRF) patterns in Dutch Warmblood horses during a right fore-leading canter.
• The researchers aimed to use these findings to create a reference model of a standard horse, which could be used for evaluation and comparison purposes, particularly in the context of jumping horses.

Findings

• The data collected revealed a clear pattern of asymmetry in the GRF produced by the four limbs of the horse during a canter.
• This asymmetry was expressed through different contributions of each limb to the horse’s movement: The leading right forelimb primarily served to decelerate the horse’s body, the trailing left forelimb pushed the body forward and also contributed to its deceleration, while the trailing left hind limb propelled the body. The leading right hind limb maintained a dual role of both deceleration and propulsion.
• The study found that when compared to the maximum vertical load exerted by the leading right forelimb, the trailing left forelimb bore 25% more weight. The right hind limb experienced a slightly lesser load, and the left hind limb bore about 80% of the leading forelimb’s load.

Implications of the Research

• The findings of this study can significantly impact the evaluation of jumping horses. The GRF patterns captured can serve as a benchmark for determining a horse’s performance, overall health, and potential risks of injury.
• Understanding these force patterns may also influence training strategies to ensure a balanced force distribution and minimize the risk of overload-related harms.
• The pattern of GRF can also indicate specific abnormalities or imbalances in a horse’s gait, which can help early diagnosis and intervention in pathological conditions.
