The relationship of some biomechanical variables of the final steps and ascent with the achievement of the long jump

الملخص

This study aims to identify the values ​​of some biomechanical variables of the long jump’s last steps, the values ​​of some biomechanical variables and rise of the long jump, the values ​​of some biokinematic variables and the achievement of the long jump, and the relationship between the values ​​of some biomechanical variables of the last steps, The rise and the achievement of the long jump. The sample consisted of five advanced jumpers in the West Asian Athletics Championship for Long Jump, which was held on (30-5-2024) at the Palm Trunk Stadium in Basra Governorate. Video recording, modern scientific techniques(Maxtraq) and programs were used in the analysis to extract the biomechanical variables to be studied. In addition to using the drawing scale in the exploratory and final experiment. The legal attempts were given according to the international law of athletics for the long jump. The best attempt was taken and analyzed for each jumper in the longest distance. After obtaining the raw values, they were processed statistically using the statistical package (SPSSV.21), which included the arithmetic mean, standard deviation, coefficient of variation, and the test (R) for correlations. The results obtained were discussed, in addition to making some conclusions and recommendations that are consistent with the current research on the long jump for advanced jumpers at the West Asian level participating in the championship

The researcher concluded the following:

-Many significant correlations appeared within the correlation relationship between some biokinematic variables and achievement in the long jump event, including (impact angle - take-off angle - angular difference - angular velocity - peripheral velocity - last step time - last step speed).

--Many significant correlations appeared within the correlation relationship between some biokinematic variables and achievement in the long jump event, including (linear momentum - kinetic energy - power – strength)
