Inertial properties of Dutch Warmblood horses

The complete set of three-dimensional inertial properties (mass, density, contre of mass, inertial tensor) was determined in 26 segments of six Dutch Warmblood horses. The measurements were performed with frozen segments similar to the procedure described by Lephart (1984, J. Biomechanics17, 537–543). Based on these data linear regression models were developed for the estimation of inertial properties in living horses. The reproducibility of the dissection procedure was found to range between 2 and 9%. Both mean values and regression models are presented for all parameters. The mean standard error of estimation was 8% for the segment mass, 3% of the segment reference length for the position of the centre of mass, and 17% for the moments of inertia.
