A Theoretical Study On The Position Capacity-Cultivation Of Volleyball Libero Players

In order to bring the attack and defense into balance, and make the volleyball match more wonderful and exciting, FIVB (Federation International de Volleyball) carried out the rule of libero players in 1999, and added"the acting libero and the reserve libero"clause in 2009. Libero players'reception and defense is obviously better than other players and they play a crucial role in a match, which could not be replaced by other players in other positions. It will give a great impetus to the cultivation and usage of libero players in the future. While, at present, there are few theoretical studies on the cultivation of volleyball libero players, not to mention the theoretical study on the position capacity-cultivation, which has great relationship to libero players'performance in the match. By means of expert questionnaire, expert interview and site observation, this paper makes a theoretical study on the position capacity-cultivation of volleyball libero players. The results from the study suggest that:1. The position capacity-cultivation of volleyball libero players refers to the long-term education and trainning for the volleyball libero players, which will help to obtain, improve and maintain the position of volleyball libero players'competitive and subjective condition. The theory of the position capacity-cultivation of volleyball libero players is composed of four parts: 1) the cultivating objectives of the position capacity. 2) the structural elements of the position capacity. 3) the division of the position capacity-cultivation cycle and its stage tasks. 4) way of cultivation, selection of the means and control of the load.2. The cultivation of volleyball libero players'position capacity aims at cultivating the defense core of the team, which has the qualities of stable psychological state, quick thinking, excellent physical condition and masterly skills. It has five sorts of objectives: skill, physical ability, tactics, psychology and intelligence.3. The structural elements of volleyball libero players'position capacity include skill elements, physical ability elements, tactical elements, psychological ability elements and athletic intelligent elements. 4. The cultivation of volleyball libero players'position capacity is divided into five stages: basic position training stag(efrom the age of 13 to 16), position capacity improving stage(from 17 to18), the position capacity improving stage(from 19 to22); the optimal stage of performance stage(from 23 to 32) and the capacity retaining stage.(after the age of 33)5. The periodical tasks of the position capacity-cultivation of volleyball libero players are as follows: The all-round basic training stage: to orientate and lay an all-sided foundation for those possible volleyball libero players; The basic position training stage: to confirm the cultivable person and make sure they possess the basic position performance qualities; The position capacity improving stage: to work at the skills of position capacity, physical, tactical, psychological and intelligence with special care, enrich the game experience vigorously, enhance the position capacity spaces the comprehensively ; The optimal stage of performance stage : to enhance the position capacity spaces the comprehensively and achieve the best state, realize the athletic value of themselves, and create good results; The capacity retaining stage : to slow the decline of the optimal stage of performance, and continue their sports lives, promote the growth and development of the young libero players.6. Defender in the the position capacity-cultivation of volleyball libero players phase of different cycles, Should be based on the age of athletes cycle characteristics and the specific objectives and tasks,targeted training methods and means of selection and reasonable exercise control of the quantity and intensity.
