Research On The Index System Of Beijing Juvenile Sports School Men Long-jumper's Specific Strength

Research purposes:the modern competitive sports practice shows that any competitive sports specific training primary objective is to improve the athletes excavation and athletic ability. Athlete's athletic ability consists mainly of physical fitness, skills, intelligence and mental abilities in four areas. In modern athletics, athlete's physical fitness level is the dominant and central position in their competitive ability of the constituent elements, while the power quality is an important component of physical fitness and the basis of other qualities. Long jump is the leading class in speed-strength sports project. Therefore, athlete's strength training is essential. Through the research prove, physical fitness class project, track and field athlete's high and low levels of specific strength training have directly affects in athletic performance. If the coach wants to control the quantitative training process for athlete's special strength and to make the training develop towards the predetermined direction, the essential premise is to set up a training model of special strength which was closely related special performance. Junior long jump athletes are the basis for the development of China's long jump, so to establish a juvenile men's long jump athlete specific strength index system and evaluation criteria is the current training situation and the rapid development of science and objective requirements, but also the important measures to develop our young men's long jump level. By using the method of document study, investigation, factor analysis, Grey connection analysis, regression analysis, and after probing into the composed indexes of the index system of the Juvenile Sports School in Beijing Men's long jump athletes special strength, the anticipatory model of special performance, the evaluation methods and evaluation standards of special strength, the major results are obtained, that is:Firstly, the essay has established twelve general useful indicators of the special strength for Beijing Juvenile Men's long jump athletes in training. It shows:five one-foot long jump run-up; standing triple jump; jump the deep long-jump; five stride run-up jump; standing five stride Jump; weight-bearing lunge for a continuous leg jump; straight legs and jumped five hurdles; for 30 seconds dumbbell arm; snatch; after throwing Shot-put;high-turn;before throwing shot put.Secondly, initially established the Beijing Youth Men Long Jumpers strength quality index system, mainly by the upper swing strength of fast-Factor (30 seconds dumbbell arm), the coordination of trunk muscle force and systemic factors (after throwing shot put, snatch, high-turn), lower extremity Quick take-off power factor (standing triple jump, five one-foot long jump run-up, deep jump and long jump, five stride run-up jump, standing five stride jump, weight-bearing lunge for leg straight jump) component.Thirdly, the Beijing Sports School Junior Men's Long Jumpers performance indicators and specific strength prediction model are initially set up:Y=1.730+0.102 X8+0.242 X9+0.70 X10-0.022X5. In the training practice, this model may provide a reference to coaches with the scientific diagnosis of athletes and the development level of special strengthFourth, The comprehensive evaluation standards of special strength quality standards are set. up for Beijing Sports School Junior Men's Long Jumpers (The comprehensive evaluation standards of special strength quality, the individual evaluation standards of special strength quality balance degree level, the balance degree evaluation standards of athlete's comprehensive development level of special strength quality and special achievement). These results can help coach to make clear training direction, to determine training focalization and to provide the theoretical basis for special ability training.
