A Study On The Relationship Between The Body Composition Of The Women's Body-building And The Performance Of The Competition

Objective: through a large number of related investigations and taking the female athletes participating in the 2018 Shanghai Fitness and bodybuilding Championship and Open as the research object,this paper measures and analyzes the differences of their main body composition indexes and their influence on the competition results,in order to provide a data introduction for the female fitness athletes to choose the competition items according to their own conditions,to design the training plan scientifically and to prepare actively for the competition.Methods: by using the methods of literature,interview,measurement and mathematical statistics,this paper studies and analyzes the body composition of athletes,probes into the characteristics of body composition of fitness athletes,and analyzes the influence of various indexes of body composition on their competition results.Result: 1.In women's fitness and women's fitness programs,the measured data and related research show that the body composition of athletes has a certain impact on the achievement of competition results.2.In the women's physique,the top three athletes in the higher height group showed significant differences in weight loss,muscle content,skeletal muscle content and body fat ratio,p <0.01,while in the lower height group,the average of the top three athletes were higher than those in the latter group,and there were significant differences in skeletal muscle content and percentage,p <0.05.3.In the female bikini event,the first three athletes in the bikini college student group were slightly higher and lower in fat removal weight,muscle weight,skeletal muscle weight and percentage than the latter athletes,but there was no significant difference,p value was greater than 0.05,but the body fat rate was slightly lower than that of the latter athletes,but there was no significant difference between the three athletes in the bikini group,and the p value was higher than 0.05 in the bikini college student group.In the bikini social group,only in the lower height group,the fat weight,muscle mass(p < 0.01)and skeletal muscle content(p < 0.01)showed significant differences.4.In different female fitness events,through variance analysis,it is found that there is no significant difference in the main body components among the top three athletes in different events,taking into account the influence of the height group.Conclusion: 1.Fat free weight,muscle content,body fat rate and skeletal muscle content are the main body component indexes that affect the competition performance of female fitness bodybuilding athletes,and can be used as a reference index in the process of athletes training and preparation.Moreover,the influence of the main body components of different women's fitness items on the competition results is different,so the reasonable analysis and selection should be carried out according to the characteristics of the competition items when choosing the competition items and carrying on the physical exercise.2.In the women's fitness project,through the measured data and related research,it is shown that the fitness athletes' body composition index has a high correlationwith the competition score,indicating that the body composition has a certain effect on the achievement of the competition result.3.The average values of muscle content and body fat rate of the top 3 athletes were 40.07% and 15.3% respectively in women's fitness events,which could provide reference data for female gymnasts in the future training and preparation.4.In the women's physique event,the average of muscle content and body fat rate of the top 3 athletes in the following groups of 163 cm were: 43.17 kg and 9.20%;The average values of muscle content and body fat rate of the top 3 athletes in163.01 cm group were 12.73% and 12.73% respectively,which could be used as reference data for female athletes in future training and preparation.5.In the female bikini event,the muscle content and body fat rate of the top 3athletes in the bikini group A were 12.80% and 12.80%,respectively.In the bikini B group,the average muscle content and body fat rate of the top 3 athletes were 11.87%and 11.87%,respectively.Provide reference data for women bikini athletes in future training and preparation.
