A Study On The Response Effect Of Response Speed ​​Quality Intervention Exercise On Juvenile Sprinters

make full use of the sensitive period of development of adolescent reaction quality,improve response quality level of athletes in sprint stage of basic training, which is of important realistic significance to lay the foundation for cultivating high level of sprinters. This paper takes Tianjin city Nankai District amateur sports school 50 junior sprint athletes as the research object, the research method of the integrated use of literature data method,experimental method and mathematical statistics method, based on the original training program on the object of study the implementation of a 12 week intervention reaction speed quality training, to explore the reaction speed quality training of Juvenile Sprinters’ startintervention the reaction efficiency and the conclusions of the research are as follows:(1) the implementation of reaction speed quality before and after the intervention of practice,the experimental subject of sound simple reaction time and light simple reaction time testscores were significant differences.(2) the reaction speed quality training in the form of the game as the main content, there are significant to improve the motion response of male and female athletes of teenagers and at the completion of exercise effect.(3) targeted to the athlete’s tactile, auditory and visual aspects of the identification andselection of the direction of the training, help to improve the Juvenile Sprinters in crouching start in the starting gun sound discrimination and selection and improve the player’s attention.(4) the implementation of the "reaction speed quality" intervention practice, male athletes after the experiment the reaction time increased by 2.34%, female athletes after the experiment thereaction time increased by 1.98% before and after the experiment, male and female athletesstart reaction results there are significant difference test.At the same time, reaction speed quality training of Juvenile Sprinters to put forward the following suggestions:(1) in the process of speed training scheme design response, load should be appropriate;training methods and means of choice in addition to the reaction speed training aspects, but also have the training content associated with starting technique actions, and to novel,interesting, attractive; in the training time arrangement in addition to each training time can not be too long, select the time period of training should be appropriate, try to choose the timebetter functional state of athletes.(2) the coaches to the special period to seize the development reaction speed quality ofyoung athletes, the implementation of scientific and effective reaction speed quality training program on adolescent dash players, in order to improve the starting reaction when athletes.(3) from the tactile, auditory, visual athletes receptors to outside stimulus intensity, the sensitive degree of the central nervous system of the received complex informationprocessing speed, make the action of effector sensitive degree of neural system, conduction time and start technology improvement to improve the athlete’s reaction time.(4) in reaction speed quality training of juvenile sprinter first to physiological and psychological features of young athletes to make the correct analysis, the training arrangements in theconventional training prior to starting technique, for the athletes’ training, in the training process to improve the athlete’s attention and regulate their emotional state.(5) the reaction speed quality of each training time not too long, should be arranged in 20 minutes.
