Study On Competitive Performance And Conditional Extremum Of Elite Aerobics Men Individual Athletes In China

Competitive aerobics men’s single is a weak event in China,which is in sharp contrast to the achievements of collective events in international competitions.In order to improve the competitive level of men’s single events,this study uses literature method,expert questionnaire method,optimization method,mathematical statistics method,video analysis method,taking the concept of competitive performance of aerobics as the logical starting point,studies the connotation,constituent elements and index system of competitive performance of aerobics.By collecting the index data of men’s single athletes under the2017-2020 rules and analyzing their data characteristics,the objective function and constraint function of the conditional extreme value model of men’s single athletic performance of aerobics are established,and the conditional extreme value of athletes’ athletic performance is obtained.At the same time,the model can also be applied to other aspects.The main conclusions are as follows:1.Competitive performance of aerobics refers to the competitive ability of aerobics athletes by demonstrating complete sets of movements in the competition,the comprehensive performance of other sub-abilities dominated by skills,or the competitive level of aerobics athletes shown in the competition under the rules of aerobics scoring.The competitive performance elements of aerobics include skills,physical ability,tactical ability,psychological ability and knowledge ability,and the forms of expression are different aspects of difficulty performance,operation performance and transition connection performance.2.The aerobics athletic performance evaluation indexes from the requirements of the rules,which use music and music,space mainly reflects the player’s tactical performance,knowledge,exercise content,subject content,artistic quality mainly reflects the physical performance,skills and tactics,complete points mainly reflects the physical performance of athletes,psychological performance,The difficulty score mainly reflects the skill performance and physical performance of athletes.3.The objective function equation of the extreme value model of men’s single athletic performance is Y=0.5X1+X2+X3;The constraint function is expressed as the functional relationship between artistic score and completion score: Y=1.15+0.885 X and the constraint function of each index of individual competitive performance.The extreme value of individual competitive performance can be calculated by the objective function and the constraint function.4.The competitive performance of men’s single in aerobics can be used to predict the result of men’s single more accurately,and the error value can be specially accepted,and a set of high-quality arrangement ideas can also be analyzed through the residual of the predicted value.According to the conditional extreme value model of men’s single performance in aerobics,we can scientifically set the training target and choose the best combination strategy by reverse solving the objective function.
