A Study On The Determination And Evaluation Of Soccer Sense Of Young Women Table Tennis Athletes In Guangdong Province

Scientific selection is an important part of the table tennis reserve personnel training.Feel as a of table tennis athletes selecting important physiological and psychological function index,the proportion of occupies a very important,it is based on their ability of athletes specialized sensory perception ability of synthesis reaction,an athlete technical level and competitive ability selection and evaluation of a key indicator.Therefore,in order to more scientific evaluation of the athletes feel levels,provide scientific evaluation and diagnosis for the coaches to make table tennis reserve talented person selection more scientific,systematic and standardized,build the table tennis players feel indicators measuring and evaluation system has very important significance.In this paper,by using the method of documentary,expert interview,questionnaire survey method,measurement testing method,mathematical statistics and logical analysis,feel were determined and the evaluation of table tennis players,build the evaluation index system of young women table tennis players feel in Guangdong province.The conclusion is as follows:?1?Set up the evaluation index system for women's table tennis players in Guangdong province.It consists of four primary indicators,14 secondary indicators and 28 tertiary indicators.And factor analysis to get through field testing index data layer class of typical indicators,the indicators of choice reaction time respectively the X₃,X₅ time perception,3.5 meters slide S₅,maximum grip strength WL in succession,crook proneness S₆,forehand attack J₆,send back spin J₅,1 min to bounce forehand attack J₃ and backhand chop J₁₀,a total of nine typical indicators.To avoid the collinearity problem between indicators,through further regression analysis,finally confirmed six measures of effective typical,choice reaction time respectively the X₃in succession,crook proneness S₆,step 3.5 meters of sideswipe S₅,maximum grip strength WL,forehand attack J₆,backhand chop J₁₀.?2?Determine the weight and evaluation model of each evaluation index.According to experts and coaches on the results of the survey to the importance of the indicators,using the weight calculation formula to get the weight of each index,more intuitive accurately reflects the indicators in the build of Guangdong young women table tennis players feel important degree in measuring and evaluation system for the research of this paper provides an objective theoretical guidance,but also improves the objectivity of evaluation results.The evaluation model equation of each index layer is as follows:Y_X=0.12X₁+0.14X₂+0.13X₃+0.12X₄+0.12X₅+0.12X₆+0.12X₇+0.12X₈Y_S=0.15S₁+0.14S₂+0.14S₃+0.14S₄+0.15S₅+0.14S₆+0.14WLY_J=0.09J₁+0.088J₂+0.093J₃+0.088J₄+0.094J₅+0.089J₆+0.092J₇+0.093J₈+0.096J₉+0.088J₁₀+0.089J₁₁Comprehensive evaluation index model of ball sense:Z=0.31Y_X+0.27Y_S+0.42Y_J?3?Establish a typical index weight and evaluation model for the ball sensation.According to the analysis results,the typical indexes of the index layer of the female table tennis players in Guangdong province were obtained,and the psychological indexes were:X₃ in the choice of reaction time;Physiological index:maximum grip WL;The special body quality index is:3.5 m side sliding step S₅,seat body forward bending S₆;Special technical indicators are:forehand attack J_6,backhand rub J₁₀.In the whole typical index system,the weights of various indexes are ranked as:X₃>WL>J₆>J₁₀=S₅=S₆.In order to make the coaches have a more convenient and effective evaluation on the athletes'sense of the ball,a typical evaluation model equation for the female table tennis players in Guangdong province was established:Z=0.19*X₃+0.32*?0.5S₆+0.5S₅?+0.17*WL+0.32*(0.5J₆+0.5J₁₀)?4?The evaluation criteria for the players'feeling of the table tennis players in Guangdong province were formulated.According to the Guangdong young women table tennis players feel the ability of comprehensive evaluation,feel the comprehensive score of 3.55?3.55?above for excellent level of performance between3.18³.55?3.18?for level,good feel scores between 2.57³.18?2.57?for average,scores between 2.36².57?2.36?belongs to the lower level,score below 2.36 points for the poor.It provides a theoretical basis for the coaches to provide objective evaluation criteria for the athletes'sense of the ball,and to develop the training plan for the athletes in the future,and to improve the overall level of the players.
