Use of a dynamometric horseshoe for analysing race track characteristics at high speed

Measuring ground reaction forces (GRF) is a relevant approach to study the interaction between the ground and the hoof. Forceplates are the most commonly used but this technique is not well suited to compare different ground surfaces at high speed. An on-board technology has been developed to measure forces directly under the hoof. Although similar devices have been developed, they either measure only the vertical GRF (see Kai 2000), or they are too heavy (see Rollot 2004, Roland 2005).
