Abstract: In the publication “Movements of trunk and back of the horse from a riders view” in the TU 59, 327-334, 2004 the author suggested that academic research is necessary to determine measurable parameters for these agents of the horse's movement.
The discovery of the importance of the trunk-back-movements for a sensitive and horse-oriented riding style is closely connected to the development of the balanced seat and the technique of receiving signals from and sending signals to the horse at the right time (riders would say: “the feel and the impact”). The history of this interaction between horse and rider can be traced for four and a half centuries. A short digest will be published here later. Again the studies result in a demand for interdisciplinary academic research.
There is an urgent need to clarify the impact of the riders's seat and aids (two more pillars in the art of riding) in the interest teaching riding correctly and more efficiently at the so-called 'basis' of our sport.
