THE APPLICATION OF THE BIOMECHANICS MODELS FOR THE CONTROL OF THE "IMPROVEMENT TARGETS" IN 110m MEN'S HURDLES

Athletic performance in 110m men's hurdles is determined by a succession of kinematic, dynamic and anthropometric characteristics. The purpose of this research is to present a methodology study concerning the biomechanics of the athletic movement, through which, the determination of those contingent parameters that mainly condition the partial characteristics ("improvement targets") of athletic performance, will be feasible. The following characteristics are presented as "improvement targets" 1 .The height of the center of gravity before the hurdle clearance (takeoff), 2. The height of the flight during the hurdle clearance, 3. Horizontal take-off velocity during the support phase after the hurdle. With the method of the models we can check on the "improvement targets" in order to decide on the biomechanic characteristics that affect them, adopting a mechanical simplification of the human body, that is, the center of gravity. In the deterministic model, there is the possibility that the correlations that possibly exist among the contingent kinematic characteristics of the model are not considered, which in turn, will lead to an arbitrary differentiation. Because of this, the need for the structure of an indeterministic model based on primary data is brought about. After checking the model's equations we experiment with them in order to calculate the height of the influence of the partial biomechanic characteristics on the "improvement targets" The method of the models presents certain kinematic, dynamic and anthropometric characteristics that can be used for the direction of the training of technique
