Research On Physical Fitness And Evaluation Of Excellent Wrestlers

Research purposes: With the continuous improvement of the level of wrestling sports competition,the physical structure characteristics of the excellent wrestling athletes are also adapting to change,systematically study the physical structure characteristics and evaluation system,and find out the special characteristics of the wrestling athletes' physical fitness.And physical training provides a theoretical basis.Research methods: The Beijing Sports University Competitive Sports School has23 wrestling men's and 24 women's.The subjects' body shape(upper limb length,shoulder width,body fat percentage,etc.)and body function(maximum oxygen uptake,Anaerobic power,heart index,maximum ventilation,relative vital capacity,serum testosterone,blood urea,etc.),physical quality(100m,400 m,,high turnover,grip strength,sitting body flexion,etc.)related indicators test.Independent sample t-tests were performed on athletes of different groups(general group,elite group)and elite groups(male: medium,weight class;female: small,medium).Factor analysis was carried out on each indicator of the physical system of the elite group,and representative indicators representing the physical system were analyzed,and then the percentile method was performed.Classification and analysis of individual strengths and weaknesses of athletes.Research results:1.Elite group body fat percentage,Quetelet index,upper limb length,serum testosterone,blood urea,heart index,relative lung capacity,relative average power,relative maximum oxygen uptake,400 m,pull-ups,high turn,etc.In the normal group(P <0.05).At the same time,according to the level,most of the indicators of the body shape of the elite group increased with the increase of the competition level.There were significant differences in the aerobic,anaerobic capacity indicators and physical fitness of the different levels of body functions(P<0.05).).2.Through the dimension analysis analysis of the indicators of the factor analysis method,the indicators of the weight of the elite team's wrestling athletes are:the Ketolai index and the upper limb length;body function: relative average power,relative maximum oxygen uptake Physical fitness: high turn,400 m.Research conclusions: The elite athletes have special body shape characteristics such as lower body fat percentage,longer upper limbs and stronger limbs,which are beneficial to the performance of the game;Strong myocardial contractility,lung ventilation and ventilation reserve,strong aerobic,anaerobic capacity,higher androgen levels.The physical function characteristics of the load wrestling project with strong recovery ability and adaptability to the training load;and the overall comprehensive physical quality characteristics represented by the power quality.With the improvement of the training level,the athletes of different levels will adapt to the special characteristics of the corresponding level.Representative indicators for evaluating the physical fitness system include the Clayto index,upper limb length,relative average power,and high turnover.
