KINEMATICAL MODEL OF HURDLE CLEARANCE TECHNIQUE

Abstract

The objective of our study was to determine the major kinematic parameters that generate a model of hurdle clearance technique on the 4th hurdle in the 110 metres hurdles. A biomechanic analysis was performed on one of the best hurdlers, a world record holder, Colin Jackson. The analysis of the hurdle clearance technique was made by means of 3D kinematic system ARIEL. The subject of the study was kinematic analysis of the take-off, flight and landing. The results showed that the rational technique of hurdle clearance is defined by the following parameters: horizontal speed of CM (centre of mass) in the moment of take-off, the level of CM in take-off, speed of the swing leg during take-off, take-off angle, time of the flight over a hurdle, level of CM above a hurdle, horizontal speed of CM in the landing phase, level of CM in the landing phase, and contact time in the landing phase.
