• TITLE: The Impact of Push Phases Takeoffs Angles on Performance in the Dominant Hop Technique

  KEYWORDS: Push Phases Takeoffs Angles, Performance, Dominant Hop Technique

  ABSTRACT: The purposes of this study were to compare the technique dominant hop used by elite world triple jumper to determine the impact of modality angles push phases allowing the elite to exceed 17-meter. Bing Yu (1982) confirmed that, any athlete came to the typical (39%:30%:31%) ratio distribution as big performance in the hop phase as modality to the Russian technique (which emphasizes the hop phase). From that our subjects were the results of (Idowu P. 3rd, Copello A. 6th) World Athletics Championships 2009 and their results at the World Athletics Championships 2011 (Idowu P. 4th, Copello A. 5th), where our elites of world championships practiced the hop dominant technique as technique in the two competitions. In the lack of new technology, modern measuring instruments kinematics or kinetics. Our study was based on rapports take-off angels as measure of stride length jump distance based on the results of the practice (the same elites and the same technique). After statistical treatment, we confirm that: 1) the take-offs angels push phases are a criterion mean to assess and judge the level of application of elite; 2) any less change take-offs angels pushes in step phase change the angular momentum created by hop phase.
