The Effect of Differences Intensity on some Biomechanical Variables During Two Style of Squat Performance

Khaled M. Atiyat, Mohammad L. Al-Quran

Abstract


This study aimed at determing the effects of differences intensity on some Biomechanical variables through two style squat performance. The description experimental method had been applied in ten persons as a samples. Five athletes (male) from the national team for weights lifting represented different weight groups and five athletes (male) practicing free squat for body fitness and keeping a good health. The study was registered by a video camera (Sony) gives 25 pictures per second, in which every player made three trials of the weights: 50 %, 75 %, 90 % from the higher weight was lifted for the free squat exercise and three trials on Smith Machine. The results of the samples were analyzed by the slow motion with a (Sony) video, which gives 50 picture per second, after that the drawing inserted to the (AutoCAD 2000) computer program, which gave the ability to take many operations related with dimensions, angles and so on. In the statistical treatment, the researchers showed differences with a statistical reference during the squat exercise in different intensity in the researcher recommended to using smith machine in practicing squat exercise, because the high value for this machine to make us get practicing in a good, right technical picture that work to protect us of any hits or injures.
