Asking for impulsion before the previous 3 scales (rhythm, suppleness, contact) are established is a recipe for disaster. Only once your horse can maintain his rhythm, and is supple enough with a responsive contact, will his body physically be able to manage the demand for impulsion. If asked for before these training milestones are achieved, impulsion will only produce running, and not the controlled power of engaged hind quarters.
Too often, judges find themselves making the well-known comment: “Do not confuse speed with impulsion”, and yet many riders continue to do so.
So what IS impulsion?
The FEI defines impulsion as: “The transmission of controlled, propulsive energy generated from the hindquarters into the athletic movement of the eager horse. Its ultimate expression can be shown only through the horse’s soft and swinging back and is guided by a gentle contact with the rider’s hand.”
In a nutshell, impulsion = power, but this only translates into a usable feature when your horse’s body is supple enough to permit the energy to flow through it, and comes with the controls you need to direct it.
