Abstract

The study aimed to identify the values of some biomechanical variables during the hurdle clearance steps (1-4-8) and their relationship to performance in the 100-meter hurdles for advanced female athletes. The researcher used the descriptive approach with a correlational method, as it suits the nature of the study. The study sample was intentionally selected and consisted of five (5) female hurdlers from the advanced category who represented their clubs in the Iraqi Clubs and Institutions Athletics Championship in the 100-meter hurdles. These athletes were officially registered in the records of the Iraqi Central Athletics Federation for the year (2021–2022) and had achieved the best results in the Iraq Championship.


The data were statistically processed using the arithmetic mean, standard deviation, coefficient of variation, and Pearson correlation coefficient. Based on the analysis, the researchers reached the following conclusions:



  1. There was a significant correlation between some biomechanical variables in the flight phase before the hurdle and performance in the 100m hurdles, as follows:


  • Between the first hurdle and performance (variable 2)

  • Between the fourth hurdle and performance (variable 5)

  • Between the eighth hurdle and performance (variable 4)


There was a significant correlation between some biomechanical variables in the flight phase after the hurdle and performance in the 100m hurdles, as follows:

  • Between the first hurdle and performance (variable 1)

  • Between the eighth hurdle and performance (no correlation found)


There was a significant correlation between some biomechanical variables in the hurdle clearance phase and performance in the 100m hurdles, as follows:

  • Between the first hurdle and performance (variable 3)

  • Between the fourth hurdle and performance (variable 1)

  • Between the eighth hurde and performance (variable 2)
