THE ANALYSIS OF HURDLING STEPS USING AN ALGORITHM OF COMPUTER VISION: THE CASE OF A WELL-TRAINED ATHLETE
Journal Title: Medycyna Sportowa - Year 2014, Vol 30, Issue 4
Abstract
[b]Background.[/b] In this paper, a markerless method for tracking the motion of a person as a tool to estimate kinematic parameters of a hurdling step was used. [b]Material and methods.[/b] The study is conducted on a hurdler of top sports level. Video sequence recording was conducted in simulated conditions of the start in 110 m hurdle race. Kinematic parameters were determined on the basis of the analysis of image sequences recorded using a single camera with the frequency of 100 Hz. The method proposed in this paper does not require any custom-designed clothes, markers or other technologies facilitating estimation. [b]Results.[/b] In this study, we present quantitative data on 21 kinematic parameters and their variability throughout the hurdling step. The results confirmed a high level of sports form of the athlete subjected to the study. [b]Conclusions.[/b] The proposed method used to estimate kinematic parameters may be used in the assessment of progress in the training of hurdlers, notably in terms of technique preparation.
