Research On The Construction Of The Index System Of Winning Factors In Men’s Body-building Competition

In recent years,the body-building project has been developing continuously,and the men’s body-building competition has rapidly become a popular project due to its project characteristics.However,there is still a large gap between the overall level of Chinese body-building athletes and the high-level athletes in Europe and America.Throughout the research on body-building sports in the field of sports research in China,there is a lack of research on the rules of victory in the field of men’s body-building and related research.By constructing the index system model of winning factors in men’s body-building competition,this paper accurately analyzes the weight of winning factors in the current men’s body-building competition.It can optimize the winning points,strengthen the weaknesses,check the gaps and make up for the deficiencies of the athletes according to the winning factors in the men’s body-building competition,so that the body-building special teachers and coaches have a more objective understanding of the athletes’ special level,and guide the selection of body-building athletes for coaches Provide valuable reference and suggestions for daily training and competition.This paper takes 10 bodybuilding athletes(all of them are national or international athletes)and 10 national and above referees of the 2022 China National Fitness and Bodybuilding Active National Team as the object of investigation,and takes the construction of the index system of winning factors in men’s bodybuilding competition as the object of study.Through literature review,expert interview,video analysis,Delphi method,analytic hierarchy process and mathematical statistics,this paper conducts screening Research and analysis.The study draws the following conclusions:(1)The main research result of this study is "the construction of the index system of winning factors in men’s fitness competition".The whole index system is composed of 6 first-level indexes and 26 second-level indexes of body and muscle shape,skills,psychological ability,tactical ability,sports intelligence and other factors.Among them,the first level index is the competitive ability of male bodybuilders,and the second level index is the winning factor of male bodybuilders.(2)Through the analytic hierarchy process,the weights of the first-level indicators are ranked from high to low: body and muscle shape(0.5526),skill(0.1428),psychological ability(0.0935),tactical ability(0.0681),sports intelligence(0.0935),and other factors(0.0494).Among the secondary indicators,the comprehensive weight coefficient in the top ten,from high to low,are: muscle separation,muscle dimension,waist to shoulder ratio,stage performance,technical action standardization,head to shoulder ratio,will quality,muscle clarity,muscle scale,and oil paint selection.(3)According to the structure of the index system of winning factors in men’s body-building competition and the relationship between different levels,the degree of muscle separation,muscle dimension,waist to shoulder ratio,head to shoulder ratio,muscle clarity,and muscle scale belong to body and muscle shape factors;Stage expressive force belongs to the factor of sports intelligence;The standardization of technical actions is subordinate to skill factors;Will quality is subordinate to psychological ability;The selection of oil paint is subordinate to tactical ability.(4)The study found that among the first-level indicators of winning factors in men’s body-building competitions,the shape of body and muscle has the greatest impact on winning the competition.In the body and muscle shape indicators,athletes should fully understand the development requirements of men’s body-building events and the judging criteria of judges,and focus on the development of muscle shape in training,not just increase the dimension of muscle.(5)The study found that the standardization of technical movements is the most important in the men’s body-building competition among the skill indicators.The body-building athletes must regularly carry out the modeling training of the prescribed techniques after the daily training,so as to form the muscle memory of their own dominant modeling,make the positioning movements of the four turns of the men’s body and the walking of the prescribed routes skilled,and be able to show their own advantages and distinctive personal characteristics.(6)The study found that in the psychological ability,the will quality of athletes is more important than the stability of psychological quality,and psychological ability is the guarantee for athletes to train and participate in competitions.Coaches should give guidance and help to athletes’ psychology in time,and consciously pay attention to the cultivation of athletes’ psychological ability.(7)The study found that in the tactical ability,the selection of oil paint is more important than the selection of competition clothes and makeup.The athletes’ oil paint,competition clothes and makeup are directly displayed to the judges on the field.The oil paint must select the special oil paint allowed by the competition,and the depth of oil paint should be selected according to their skin color.The following recommendations are made:This paper takes 10 bodybuilders and 10 referees at the national level and above of the 2022 China Gymnastics Active National Team as the subjects of investigation.The experts interviewed include the active members of the national team,but the number is small.In the later research,we can interview the top three of each group of men’s bodybuilding events in the championship,improve the sample size,and also improve the index system of winning factors in men’s bodybuilding competitions.
