The effect of special exercises on some biokinematic variables for the hopscotch and step stages and the completion of the triple jump for students

Abstract

The research aimed to prepare special exercises and include them in the main section of the educational units and to identify the effect of these special exercises in developing some selected biomechanical variables (the starting angle, the starting speed, and the starting point height) and to achieve them for the students of the second stage (2023-2024). The researchers used the (experimental method) with a design Two equal groups (control and experimental). The researchers prepared special exercises for each variable and they 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 and for five weeks. The duration of the educational unit was (65 minutes) in which the exercises were varied for the purpose of improving the digital level of the effectiveness of the triple jump. For students, use the statistical portfolio (Spss), the most important thing that the researchers concluded was that the special exercises had an impact on developing the biokinematic variables (launch angle, launch speed, and starting point height) and the digital level (achievement) for the experimental group, and that the experimental group that used the special exercises had an advantage in developing the selected biokinematic variables and the digital level (achievement). ) for effectiveness than the control group.
