التحليل الكينماتيكي لتحديد ابرز نقاط الضعف في عدو 100 متر لطلاب كلية التربية البدنية وعلوم الرياضة

The research aims to identify : The most prominent weaknesses in the kinematic variables (length, time, speed, frequency) of the step among students of the first and fourth stages of the Faculty of Physical Education and Sports Sciences/ University of Mosul in the (100) meter race for the sample .. The research problem is determined by knowing some of the kinematic variables of this activity for first-stage students and fourth-stage students and to know the most prominent weaknesses in the research variables under study in terms of (length, frequency, time, and speed) of the step and to conduct a comparative study of these variables between first-stage and fourth-stage students and the extent to which these variables under study are affected by the teaching process to develop students’ achievement in various sports activities, A sample of (28) students from the College of Physical Education and Sports Sciences/ University of Mosul for students of the first and fourth stages for the academic year (2022 AD) consisted of (14) students from each stage, as the distinguished students from the first and fourth stages were selected intentionally by running (100) meters , It was also calculated the kinematic variables of the number and frequency of steps and the total time for each student taking the test when running a distance of (100) meters by means of the assistant work team that was distributed with two in the middle of the first (50) meters and two in the middle of the second (50) meters along the distance of (100) meters. (Appendix No. 1) With the presence of a video camera that follows the student’s movement from the start line to the finish line to compare the results of the support team in terms of the number of steps and the total time in the (100) meter race, and after giving each student two attempts and calculating the best of them in terms of achievement so that the recorder can record the results after each attempt, the values ​​of the kinematic variables under study were identified after each test of the (100) meter race stages by using the physical laws and equations specific to each variable. The researcher concluded the following : - The results of the research were in favor of the first-stage students due to the significant differences in the kinematic variables (length, speed, frequency) of the step at a distance of (100) meters and in their favor. The intensity of practical lessons and training methods for first-stage students showed strengths that led to the development of physical fitness elements at a greater rate than fourth-stage students who showed weaknesses in the variables (length, speed, and frequency) of the step and the achievement of a distance of (100) meters. The researcher recommended a number of recommendations :Emphasizing the development of physical fitness elements among students of all academic levels in the College of Physical Education and Sports Sciences in practical lessons to avoid poor performance in various sports events. Coordination between practical and theoretical lessons between stages in terms of their intensity and size in a way that serves the continuity and development of physical fitness elements among students- Using kinetic analysis in the educational and training process to identify strengths, weaknesses and proper performance to achieve numerical and high achievement and various sports events
