Research On High-level Athletes' Participating In Competition Redundantly With Self-providing Competitive Apparatus

The purpose of this thesis was to focus on the issue of ?high-level athletes participating in competition redundantly with self-providing competitive apparatus?.Firstly,redundancy theory and method of automatic control were drew(into),the triple-redundancy theory of high level athletes participating in competition with self-providing competitive apparatus was put forward,and it was analyzed theoretically from multiple perspectives;Secondly,a case study method was used in this thesis to explore,analyze and discuss high level athletes? participation in competition redundantly with self-providing apparatus in case of an unexpected incident;Based on the case study,questionnaire survey and mathematical statistics methods were used to analyze the high level athletes? participation in competition redundantly with self-providing competitive apparatus in racket games;Finally,the methods of literature consultation and semi-structured interview were used to explore the customization of high level athletes? self-providing competitive apparatus of 15 Summer Olympic games events.Hope I could contribute my best to enrich and develop theoretical system of sports competition participation.The main conclusions were as following:1.The theory of ?triple-redundancy of athletes? self-providing competitive apparatus ?was due to the limits of funding,apparatus quality and maintenance,the triple-redundancy was set up as the basic principle for athletes to participate in competition redundantly with self-providing competitive apparatus,to cope with accident or incident of self-providing competitive apparatus in cometition,to meet the athletes? needs of technical and tactical selectivity,thus ensuring athletes participate in competition smoothly.2.The unexpected incident provided the athletes with two kinds of situations: it might provide an opportunity for the athletes who participated in competition redundantly,but a threat for the athletes who didn?t participate in competition redundantly.If the athletes were fully prepared in advance of a competition,they might be able to perform as well as usual with the use of the redundant competitive apparatus even if an incident happened unexpectedly during the competition;For athletes who didn?t participate in redundantly,and vice versa;After the competition,the apparatus were maintained extremely well by the athletes so that they would be a valuable supplement in the future,and who didn?t participated in redundantly might join in those who participated in competition redundantly.The three stages of athletes' redundancy participation were relatively independent and interrelated,which provided material support for the athletes to perform well in the competition.3.Among the racket games,the self-providing competitive apparatus of high level table tennis athletes was mostly dual-redundancy;the self-providing competitive apparatus of high level Tennis and Badminton athletes was mostly multi-redundancy.4.The probability of using the competitive apparatus the high level athletes bring and factors of replacing the competitive apparatus showed that the higher the athletes? level was,the acuter their sense of the apparatus were.5.To achieve true redundancy participation with self-providing competitive apparatus,the racket games athletes need choose their own racket configuration based on the characteristics of the athletes,the rackets and spare parts,including the material,parameters and performance of the rackets and the athletes? own habits(As for higher level athletes,their apparatus were basically ?private customized?);the athletes need determine the number of competitive apparatus to bring by weighing the decisive factors in redundancy of apparatus;the athletes need have training to adapt to the alternative rackets before a competition.6.There were 15 Summer Olympic games events involved self-providing competitive apparatus,among them,the high level athletes' self-providing competitive apparatus of 4 events were customized,including Table tennis,Tennis,Badminton and Bicycle,the others are not customized.The customized self-providing competitive apparatus could be divided into three categories,they were complete customization,customization combined with athletes' own preparation,customization combined with professional debugging;the non-customized self-providing competitive apparatus could be divided into four categories,they were dispensing combined with athletes' testing,dispensing combined with athletes' adapting,dispensing combined with professional debugging and leasing or using the unified competitive apparatus.7.The customization of high level athletes' self-providing competitive apparatus was precision and exclusive,which was to meet the personalized needs of high level athletes' fine sense of apparatus.
