A MECHANICAL MODEL TO ESTIMATE LEGS MUSCLE STIFFNESS COEFFICIENTS IN HORSE DURING JUMPING
Keywords: horse, modelling, muscle stiffness coefficients, take-off
AbstractThe purpose of present study was to use a simple mechanical model to estimate horses’ legs muscles stiffness coefficients in jump height during jumping a spread fenceof 140 cm high. A digital camcoder was used (25 Hz) along with Ulead Studio program in order to obtain time, related distance, and various angles in horses’ legs data. The total jump distance and time of flight for each horse were measured with a precision of 10^-2 m and 10^-2 s respectively. Biomechanical formulae have been established in order to evaluate the muscles stiffness coefficients. Three groups of leg muscles; serratus ventralis, biceps brachii, and radial carpal extensor were considered in this study and their stiffness coefficients were successfully estimated.
