The main objective of the study was to determine the impact of kinematic parameters on the results of male and female cadets in 60 meters hurdles races. Based on the main objective, the study also defined additional partial objectives, which were to (a) determine the differences in kinematic parameters between male and female cadets and b) determine the differences in results between male and female cadets. The study sample comprised a group of athletes, competitors of both sexes in the cadet category (younger male and female cadets 11–12 years of age, and older male and female cadets, 13–14) in hurdles races. For the purposes of the research, a total of 5 young male cadets, 10 young female cadets, 9 older male, and 6 older female cadets were selected. All the respondents ran the 60 meters hurdles race twice, under the same conditions. Each attempt was treated as a separate entity and all respondents had been actively competing in the 60 meters hurdles race. The variable sample was divided into the variables used to determine kinematic parameters of hurdles races, specific motoric abilities, and morphological characteristics. The study used 12 kinematic parameters that directly describe the structure of the movement (before, above, after hurdles) in hurdles races. The set of kinematic variables for estimating the running between hurdles was divided into several categories: running from the starting line to the first hurdle, running and between hurdles (time, length, number of steps), the duration of the step contact from the starting line to the first hurdle and between all five hurdles, the running variables of the duration of each leap from the starting line to the first hurdle and between all five hurdles, and the running variables of the frequency of steps from the starting line to the first hurdle and between all five hurdles. To assess motoric skills, a group of 5 specific athletes’ tests were used which indicated the horizontal jump power. To analyse the morphological characteristics, 4 measurements were used.Optojump, an optical measurement system was used to determine the kinematic parameters of running and jumping. Canon SVHS 50 Hz cameras were mounted on each hurdle, as well as on the starting blocks, and along the section from the fifth hurdle up to the finish line. The distance between the camera and the hurdles was 5 meters and they were mounted on a 1,20-meter camera stand. All measurements were recorded and monitored using computer software. After the measurements were completed, a 2D analysis was made using KINOVEA, a software for movement analysis. The data was processed using Statistica version 12 (StatSoft, Inc., Tulsa, the USA). In accordance with the objectives of this research, the following methods were used: for all the variables of motoric abilities, morphological characteristics and kinematic parameters, basic descriptive parameters were calculated. To determine the impact of the kinematic parameters (which represented the cluster of antecedent variables) on the results of 60 meters hurdles races (criterion variable) multiple regression analysis was used. To determine the differences between male and female cadets in kinematic parameters and results of the 60 meters hurdles race, the univariate variance analysis was used (ANOVA). The level of statistical significance was p < 0.05. Based on the methodological direction and procedure, three proposed hypotheses were confirmed. The various kinematic parameters from the cluster of antecedent variables turned out to be statistically more significant, impacting the results of a 60 meters hurdles race, depending on the category and sex. For female cadets, the statistically more significant variable was the distance of the swinging leg from the hurdle, the horizontal speed, and to a lesser extent, the angle between the leg and the knee during swinging. For male cadets, however, the most significant was the variable of the height between the centre of the body mass before the hurdle. The variance analysis showed that there are statistically substantial differences between younger male and female cadets. The younger male cadets had a better time in the criterion variable and they also scored statistically better on the time above the hurdles variable.
