An Experimental Study On Prior Choice Of Training Methods Of Speed Strength For Sprint Athletes Of The Youth Boys, Grade 2

Content: In athletics sports, the level of track and field influences the whole level of a country's athletics sports directly. Sprint is one of the athletic items which is the most scorching, resounding and popular one, so the research and training in this field gets much attention in every country. Sprint is the speeding programmer of typical physical energy and is catachrestic of short exercise time and fast speed .It requires that the athletes not only have been qualified with speed quality ,but with strength quality ,of which the developing standard of speed strength plays an leading and nuclear role in the construction elements of competent ability .This thesis aims to discuss the relation between the methods of training speed strength and its influencing factors so as to find a prior choice for improving the level of sprint. Through the use of approaches of literature, expert's investigation, fuzzy math, experiment, statistics, from multi-dimensional angles, this paper makes a conjoint analysis of quality and reliability of quality of speedy strength of sprint athletes of youth boys grade 2.and comes to the following conclusions:1,As the youth are during their adolescence so it is feasible to adopt various forms of jumping exercise and traditional weight exercise to develop the speed strength of the athletes .Various forms of jumping exercises can effectively improve the explosive strength of the ankles and fast contraction strength of the muscle during the sports.2,Through the fuzzy math, this paper gives an evaluation of all elements of quality of speed strength and all training methods .With its quantity conduction and analysis; it lays the certain theoretical basis for the practical exercise.3,According to the analysis of fuzzy relation and corresponding relation, this paper sets up the classification chart of training method of speed strength of youth boys sprint athletes: comprehensive development of speed strength quality, upper limb strength and leg strength.4,The concerned analysis proved that right combination of different training methods can break through specification of training ,and save training time and energy. It furthermore enriches specialized training theory of sprint, and provides the theoretical base and practical guide to improve the training efficiency.
