Construction And Application Of Evaluation Model Of Tennis Players’ Technical And Tactical Scoring Ability

Establish a scientific and reasonable evaluation model of tennis players’ competitive ability,and systematically and accurately assess the competitive ability of athletes.It can effectively use the athlete’s existing competition data,better interpret and analyze the athlete’s competitive performance in a one-stop competition.Later training and competitions provide more reasonable guidance.The competitive ability of tennis players includes many aspects such as physical fitness,skills,tactics,and psychology.This research takes the technical scoring ability of players in tennis matches as the starting point,and uses statistical analysis methods such as video observation,expert interview,and logistic regression.Research on the technical ability of outstanding male tennis players,established an evaluation model of excellent male tennis players ’technical scoring ability,enriched the evaluation methods of tennis players,and provided ideas for establishing a complete evaluation system of tennis players’ competitive ability and effective use of player data To provide a reference for the scientific development of tennis.The main conclusions are as follows:1)On the basis of expert experience and empirical research,6 competitive units that reflect the technical scoring ability of male tennis players are divided into service units,service connection units,service stalemate units,reception unit,connection unit,and connection The stalemate unit was developed,and the three-level evaluation criteria for the six-part scoring and contribution rate and the unit score effectiveness value were used to evaluate the unit’s technical scoring ability through the dispersion method.2)Through logistic regression analysis,the relationship between the indexes of technical scoring ability of excellent male tennis players and the probability of winning the game is constructed.3)Obtain a male tennis player’s technical scoring ability evaluation equation by standardizing the logistic regression coefficients,calculate the evaluation points of each player and evaluate the evaluation points as a standard percentage.And by introducing the idea of ?opponent strength and weakness,fitting the opponent strength indicator AOB to evaluate the overall strength of the player throughout the game,intuitively by modifying Butler to indicate the strength of the player’s technical scoring ability,and by modifying Butler as a reference value pair Evaluation of the player’s overall technical scoring ability4)Using the constructed technical scoring ability evaluation model of male tennis players,make a comparative analysis of the technical scoring ability of players who have not played in the game.5)Evaluation and analysis of Federer,Nadal and Djokovic’s 2018 Australian Tennis Open’s technical scoring ability through the construction of a male tennis player’s technical scoring ability evaluation model.
