摘要:The objective of this study was to establish and analyse those kinematic and dynamic parameters which to the largest extent generate efficient hurdle clearance technique as one of the most important factors of performance of hurdlers in the 110m hurdle event. Test runs from starting blocks with the clearance of five hurdles, set in accordance with the competition rules, were carried out on a sample of four male hurdlers. Kinematic analysis was performed by the use of a 3 - D Ariel video system. The dynamic parameters of the take-off and landing of hurdle clearance were determined by means of Kistler force platforms. It was found that efficient hurdle clearance technique is generated by the following factors: contact time of take-off, an optimal ratio of the braking phase to propulsion phase of take-off, the ratio of the point of take-off to landing relative to the hurdle, flight time, short braking phase in landing, high position of the centre of gravity (CG) at landing and minimal reduction in the horizontal force of the CG at landing
