Construction Of Key Indexes Of Psychomotor Ability Of MOBA E-sports Projects

In 2003,e-sports was included in the category of competitive sports,and it made its debut as an official event in the 2022 Asian Games in Hangzhou.The selection of e-sports athletes is gradually standardized.In August 2021,the National Press and Publication Administration issued the Notice on Further Strict Management to Prevent Minors from becoming Addicted to Online Games,which reduced the playing time of teenagers and required e-sports players under 18 years old not to participate in competitions.Therefore,based on the competitive characteristics of e-sports athletes who rely on their hands to control the fine muscles of mouse and keyboard,this study combines MOBA e-sports sports with psychological research to compare the differences in psychomotor ability of players at different competitive levels and screen out key indicators.It provides a scientific and effective basis for the selection of e-sports talents and promotes the sustainable development of e-sports.This study takes the psychomotor ability of MOBA e-sports project subjects of college students at different levels as the research object,and adopts the method of literature,expert interview,psychometric and mathematical statistics.This paper studies the relationship between the competitive level and psychomotor ability of MOBA e-sports subjects,the key indicators that affect the competitive ability of MOBA e-sports subjects,and the structure of psychomotor ability of MOBA e-sports subjects.140 male "League of Legends" game subjects aged 18-20 years with 2-2.5years of gaming experience were selected as psychological measurement objects and divided into silver,gold,platinum,diamond and above four different competitive ability groups.The classical paradigm of psychomotor ability measurement was used to measure the auditory response,visual response,selective response time,hand stability,hand speed,wrist speed,aiming,speed control,hand coordination,finger flexibility,wrist flexibility and control accuracy of the psychomotor ability of subjects at different athletic levels.SPSS26.0 software was used to conduct statistical analysis on the index measurement data of subjects in different competitive ability groups by using independent sample T test,clustering,regression and factor analysis,and the following results were obtained:1.There were significant differences in seven indexes of psychomotor ability(wrist finger speed,auditory response,visual response,selective response time,hand stability,hand movement speed and control accuracy)of the subjects at different segments,while there were no significant differences in the other five indexes.2.Correlation between e-sports ability score and psychomotor ability results show that the correlation coefficient between e-sports ability score and game level score of the subjects and the four indexes of psychomotor ability,namely,selective response time,wrist movement speed,control accuracy and visual response,is greater than 0.7,showing a highly significant correlation;The correlation coefficient was between 0.4 and 0.69 with auditory response,showing moderate significant correlation;the correlation coefficient was less than 0.4 with hand stability and wrist flexibility,showing low significant correlation;the other indicators showed low correlation.3.After rotation by factor analysis,a total of five factors were proposed.The high-contribution indexes in factor 1 included five indexes: wrist finger speed,auditory response,visual response,selective response time and control accuracy;Factor 2 high contribution index included three indexes: aiming,wrist flexibility and hand coordination;Factor 3 high contribution index includes hand movement speed and speed control;The high contribution index of factor 4 was only an index of hand stability;Factor 5 High contribution index is only one index of finger flexibility.4.Cluster analysis is used to cluster the first index into five categories.The first category includes six indexes: auditory response,visual response,speed control,selective response time,hand stability and control accuracy;the second category includes three indexes: finger flexibility,wrist flexibility and aiming;hand movement speed,two-hand coordination and wrist finger movement speed respectively become one category.The results are discussed and analyzed and the following conclusions are drawn:1.There are significant differences among the subjects of MOBA e-sports in the six indexes of wrist finger speed,visual response,control accuracy,hand stability,selection response time and auditory response,and those with high competitive ability are obviously better than those with low competitive ability.2.The four indexes of wrist finger speed,control accuracy,hand stability and selection reaction time are the key indexes to determine the competitive level of MOBA e-sports subjects.3.Psychomotor ability can be reconstructed into three categories: neural response ability,control ability and flexible operation ability according to the characteristics of MOBA e-sports projects.
