| With the development of trampoline gymnastics in China in the recent years, it has come to the front in China’s major trampoline events. Together with gymnastics and diving, trampoline gymnastics is a skilled and expr-essive sports event with difficulty and beauty. At the same time, tramp-oline in China has gained a place in the world trampoline field. In2008, it added two gold metals of Men’s Individual and Women’s Individual to China’s gold metal table, this thesis summarizes the interruption characteris, causes and countermeasures and suggestions in the whole set movement of trampoline, combining trampoline competition rules of International Gymna-stics Federation. By doing so, it provides references for trampolinist and coaches and further avoids accidental phenomenon in this sports event.This thesis takes interruption phenomenon in Chinese excellent tram-polinists’voluntary routine from competition videotapes of major trampoline events during2007and2011(mainly second routine and finals’routine) as its research object, and trampolinists, coaches and judges as its investigation objects. Through literature study, questionnaire investigation, video analysis and expert interview, the results show that:1. Interruption characteristics in trampolinists’routine are analyzed in the following aspects:A. In terms of places of interruption, the third mov-ement sees the most interruption, taking up15.38%of total interruption. The second and the tenth follow, taking up13.19%and12.09%respectively. The interruption rate of the fifth movement amounts to10.99%. while the sixth and ninth movements appear interrupts action ratio is less than10%, the first action no action interrupts. B. In terms of body posture of interruption, it appears in piked, straight and tucked postures, while interruption in piked and straight movements appear more frequently than those in tucked ones. C. In terms of types of interruption, front movement interruption reaches35in which double twist interruption happens the most, by68.57%, and half twist shows up more than one and a half twist, which from the twist degree see interrupt number in turn180°s turn540°; back movement interruption takes up42,which interrupts action the highest proportion is two weeks turn720°accounted for42.86%; in the final stage of turning, turn early movements appear interrupts action focused mainly on turn360°and720°, while late turning action move interrupt is focused on turn180°, for example:813/,822/action.while late twist interruption happens most in half twist, wheather in triple movements or double ones. D. Interruption most appears in the1.6degree of difficulty and double movements, and then it is triple movements, for example,the813/.822/.2. The causes resulting in interruption of trampolinists’routine are as follows:trampoline optional routine interrupted, mainly from the individual and total of two aspects of analysis, A. too much displacement while executing the routine; B. lack of height while striving to complete the routine and height malconformation between successive movements; C. weak body control while accomplishing the routine.3. Countermeasures and suggestions of reducing movement interruption of trampolinists are as follows:A. to pay attention to the training on basic movements; B. to strengthen trampolinists’proficiency and command on both single movement and whole-set movement; C. to take care of stand-ardizing and controlling trampolinists’body posture during the whole process of execution; D. to enhance special training on movement height; E. to emphasize on the stability and steadiness in the movement technique training; F. to improve trampolinists’competence consciously; G. Athletes should constantly improve their own technical movements and strengthen the difficulty of movement exercises... |
