Research aimed to prepare special exercises and aids to improve the most important Biokinematic performance indicators and include them in the main section of the educational units and to identify the effect of these special exercises and aids in developing the selected Biokinematic indicators (the length of the penultimate step, the length of the last step, the speed of the last step, and the starting angle for the three jumps). The starting speed for the three jumps, the height of the starting point for the three jumps, the length of the three jumps, the body inclination angle for the three jumps, the knee angle at the moment of leaning for the three jumps, and the time for leaning and pushing at the moment of rising for the three jumps) for students of the second stage (2023-2024).
Researcher used (the experimental method) by designing two equal groups (control and experimental), and the researcher defined the research population as the students of the second stage of the University of Karbala for the year (2023-2024), (120) students and were divided into four groups, namely (A, B, C, D). The researcher was chosen. Two sections of it, using a simple random method (lottery), to represent the main research sample, which is (63) students. Section (C), the experimental group, (31) students, and Section (A), the control group, (32) students. Two students practicing the activity were excluded. One student whose physical measurements were not suitable for performance, and the remaining (60) students.
Researcher prepared special exercises and aids to improve the most important Biokinetic performance indicators for the effectiveness of the triple jump, which were chosen by the experts and specialists, according to the relative importance of each variable, and were included in the educational units in the main experiment, which included (10) educational units that were applied at the rate of two educational units per week. The duration of the educational unit was five weeks (65 minutes), in which the exercises varied for the purpose of learning the effectiveness of the triple jump for the students. Using the statistical package (Spss) and the following statistical laws (arithmetic mean, standard deviation, simple correlation coefficient (Pearson), T-test for independent samples, T-test for symmetrical samples, Levene’s test).
The most important conclusion is that special exercises and means of assistance in the most important Biokinematic performance indicators for the effectiveness of the triple jump had an impact in improving the most important Biokinematic performance indicators (the length of the penultimate step, the length of the last step, the speed of the last step, the launch angle for the three jumps, the launch speed for the three jumps, and the height. The starting point for the three jumps, the length of the three jumps, the angle of inclination of the body for the three jumps, the knee angle, the moment of leaning for the three jumps, and the time of leaning and pushing at the moment of rising for the three jumps) for the experimental group, and that the experimental group that learned through special exercises and aids had preference in improving the most important Biokinematic performance indicators for the effectiveness of triple jump from the control group.
