Effect of some special exercises to teach effective Javelin for beginners on some purpose changes Alp iokinmatikih

Abstract

As a result of scientific and technical development has intensified competition between athletes and shows this through breaking or improve performance both by its effectiveness resulting in better achievements by engaging all human sciences and technology at the service of sport movement. < br/> Biomechanics has scientific developments through its close link with the rest of the other sciences including science albiomikanik who seek to study the movement of mechanical laws affecting all parts of the movement and analysis for the coach or the player by selecting Strengths and weaknesses which facilitates routing technique for movement towards the right model and implementation already and his mastery in addition to study the function and installation of the system according to the athlete's biological variables mechanical < br/> effectively is the Javelin of difficult events that depend on player's physical ability and physical qualities, and are affected by many variables such as mechanical (speed, power, etc.), as this feature in its fast and total transactions where the simultaneous and integrated during the phase of approaching (5 steps) and especially in the last step ( The final shooting stage) and all these stages require the coach that features the accuracy in detecting errors, and that the naked eye cannot detect errors so we resort to Imaging and motion analysis on mechanically. < br/> significance of search by using special exercises according to some variables albiomikanikih through photography and analysis to determine their relevance in the teaching effectiveness of Javelin.
