Abstract
Technological development have a big share in kinematic analysis, as in measuring muscle electrical activity, in detection of inter-relationships between body parts of the body while performing those skills. This could not be obtained without follow-up and analyze player movements during skills’ performance phases. Exercises which are similar to skills performance nature should be similar in motor composition with movements performed by player within sports competition in terms of force, speed, force time path, muscular work direction and with movements performed, i.e. characterized with existence of dynamic match between its the path and motor technique path using the same working muscle groups in the same skill. Exercise which is characterized by privacy in the development of physical and motor abilities, in certain muscles in the body, where it works on the immediate focus on working muscles and improve muscle tone and timing of contraction and extraversion necessary for sound performance; that indicate using specific exercises importance to upgrade skills performance level in various sports activities, these exercises serve skills performance and improve neuromuscular path of its performance. Researcher in the opinion that determine specific exercise through analysis using (EMG) and mechanical analysis work to give coaches the opportunity to choose - on scientific grounds - specific exercises associated with activity practiced, where it is difficult to make the equipment available for coaches, so the researcher analyzed the competition for Egypt champion under 18 years in triple jump, as well as propose a set of exercises that are similar to performance, analyze and compare the performance of triple jump to determine the most important specific exercises related to performance. Determining working muscle in practiced activity helps coaches too much on developing sound training programs, which aimed to develop functional status of these muscle specifically. The most important results include that the most important muscle are Quadriceps femoris muscle - vastus lateralis, Quadriceps femoris muscle - vastus medialis, Gastrocnemius muscle - lateral part, and Tibialis anterior muscle and that That most important muscles working in (1st and 2nd ) exercises vastus are Quadriceps femoris muscle - vastus lateralis, Quadriceps femoris muscle - vastus medialis, Gastrocnemius muscle - lateral part, Tibialis anterior muscle and Quadriceps femoris muscle - rectus femoris which are the same working muscles in triple jump and almost with the same of maximum contraction values. Working muscles (3rd, 4th and 5th) were Quadriceps femoris muscle - vastus lateralis, Quadriceps femoris muscle - vastus medialis, Gastrocnemius muscle - lateral part, and Tibialis anterior muscle
