Abstract
The presentation of average results of the subject group in biomechanical analysis reveals general trends within the sport. As each athlete's style may differ from the average performance. such results may not always assist in improving. Therefore, in this study the best performance of each elite hurdler was analyzed and suggested to understand the critical points of his technical performance. On the basis of the results obtained by the 3D kinematic analysis of the clearance of the 4th and 5th hurdles in the 110m Hurdles. some of the most important parameters to improve the performance for 3 hurdlers have been founded. As a results, it was required to increase of overall horizontal velocity and to decrease vertical oscillations of the CM before clearing hurdles for the hurdler A. For the hurdler Bit was required to decrease of vertical velocity at take off with lower parabola, and to shorten landing step by the reduction of airborne time produced by the early planting of the takeoff foot after cleaning. For the hurdler C it was required to maintain a fast running speed at landing phase.
