The Development Of Trampoline's Difficulty And The Innovative Study On The Arrangement Of Optional Exercise

The article, to the difficulty of action and movement in the sets of actions of the previous Trampoline World Championships athletes since1964as research object,researched the trend of development and the feature of innovations by analysing the number,action category and difficulty value of the difficult movement in the various sets of actions and by literature, comparative analysis and video statistics. According to the arrangement circumstances of difficult movement and complete sets of action made by outstanding athletes,it analysed the the advantages and disadvantages of the atrampoline athletes in our country and promote the level of sport skills of the trampoline athletes in our country. The results of study show that:1.Development process of difficult actionsTrampoline has different characteristics in different stages of develo-pment and historical significance, according to the summary analysis of the data, difficult course of action can be divided into three stages:performances and promotion stage (1948-1959); Internationalization stages of development (1960-1999); Leads the development of stage of the Olympic Games (2000-present).2.Development of difficult actionsAccording to flip weeks divided into:non-flip, one and two week flip mixed phases (men's five years, female1948-1969); Flip two weeks classes stage (men's five years, female1970-1987); Phase two and three week flip is kind of mixed (men's five years, female1988-2011).According to the degree of rotation divided into:turning180°,360°,540°,720°,900°,1080°, such as1440°degrees.According to the body position of different statistics86sets of actions in the body, body, comparative analysis of the number of direct action of flexor, and flexor of the stage (men's five years, female1967-1988); Flexion and straight as the primary stage (men1990-now, woman,1994-present).3.Movement difficulties typical in action By86sets action of typical routine action comparison analysis, summ-ary summarized common of action type and development trend, jumping bed movement various common of difficulty action from low difficulty to high difficulty, full of for statistics, man two week class action main has803<(39),811<(38),813o(32),813<(32),833/(30),821<(24),801<(22),811o(17),803o(13),813o(11),823<(10),801o(9),821o(7),800o(5),805(4)<,815<(2).Three week class flip key12001<(36),12001o(29),12101o(29),12003<(4),12101<(2),12201<(1).Women action two weeks main801<(39),803<(37),811o(32),800<(27),811<(25),803o(24),822(19),800o(18),801o(18),822o(9),813o(9),833/(9); Three-week major12001o(18),12001<(17). Fair use in difficult mo-vements of the arrangement, selection of appropriate to use mobilize occu-pies an important role in the movements of a set of scores.4.Theoretical basis for the complete set of movementsAccording to requirements of difficult movement in the trampoline rules on competition is organized; Aesthetic features of the complete set of competitive trampoline action; Players individual characteristics; Safety and security of players.5.Movements of the innovation frameworkTrampoline flip orientation, body position, flip weeks, rotation in deg-rees, rotation stages, contact position six factors and decides on an action. The factors themselves can change and be able to produce the number of new individual trampoline difficulty, difficulty select appropriate action according to the game needs, and players can form their own routine mode, replaced a class rank in the complete set of movements, players improve quality through innovation.6.Complete set movement arrangement principle of innovation and innovative methods.Innovations include movements of the complete set of movements of the oneness and individuality; Movements of balance and ingenuity. Innovations include reverse scheduling method of complete set of move-ments; Method of power flow and arrangement.
