Abstract

Kinematic analysis has contributed significantly to the science of sports training, enhancing it and becoming an integral part of the continuous study of the relationships between the components of motor performance and the provision of information about the nature of movement. Distinguishing between facilitating and hindering factors in any motor performance can only be achieved through accurate knowledge of all variables surrounding the performance, as well as the relationship between performance elements to achieve complete and efficient motion. This research aims to explore one of the key factors of achievement in the 110-meter hurdles event—specifically, the nature of the relationship between the length of the first stride of Iraqi hurdlers, using a higher than standard front foot placement on the starting block (an elevation of 3 cm), and certain biomechanical variables during the clearance of the first hurdle. The researcher chose this specific stride because it is considered a critical key to achieving a good performance. The research problem lies in the technical nature of the 110-meter hurdles, which requires the athlete to exert maximum speed when leaving the starting blocks and during the clearance of the first hurdle. Achieving smooth and fast clearance depends on the correct biomechanical relationships among all related variables from takeoff to hurdle clearance. The research aims to identify the relationship between the first stride length, with a 3 cm elevated front foot on the starting block, and some biomechanical variables during the first hurdle clearance for elite Iraqi national team hurdlers. The research hypothesis proposes a significant correlation between the first stride length under this setup and the related biomechanical variables. Methodologically, the researcher used a descriptive approach through a survey method, selecting a purposive sample of four advanced-level hurdlers from the Iraqi national team who typically finish the event in 14 to 15 seconds. The conclusions revealed a significant correlation between the first stride length (with a 3 cm elevation for the front foot) and the biomechanical variables in this event. Accordingly, the researcher recommends the consistent use of the 3 cm front foot elevation on the starting block by Iraqi national hurdlers, given its correlation with key biomechanical factors influencing successful first hurdle clearance.
