2014-2016ATP Annual Finals NishikoriKi Skill Tactics Research

With the development of the times,tennis technique and tactics are also constantly improving.The tennis tournaments are also more and more ornamental,and higher demands are placed on tennis players as well.This paper enriches and improves the original statistical tables,hoping to make the statistical results more comprehensive and scientific.,the 11 finals that Jin Nguyen took part in from 2014 to 2016 are selected as research objects.Some techniques and tactics used in the competition are analyzed by means of literature review,video observation,mathematical statistics and logical analysis.Statistics,in order to provide some theoretical basis for the development of men's professional tennis in China.Through the analysis:(1)In the serve stage,NishikoriKi's serve stability is better,the first goal is high,but there is no significant difference compared with the opponent.In the aspect of ACE ball and double-fault,Nishikori Ki has obvious differences with his opponents.The killing power of serving is too small,the serving score rate is low,and the advantage of serving cannot be used well to create a chance for scoring.Serve the angle of choice,starting in the right area,Kei Nishikori more options to the opponent's backhand position,the left corner of the cut corner kick out the opponent,creating opportunities for their next shot attack.However,in the success rate,the higher the choice rate of success rate is low.The second angle on the choice of more single,easy to see through the opponent.(2)Receiving phase,the main score comes from the opponent's mistakes,indicating that Nishikori can take advantage of receiving serve as passive.Pick the first line of service on the selection,Nishikori Kei mainly in the main road,with straight lines and slash lines,to take a relatively conservative tactics,the score is relatively low.Take the second serve,Nishikori Kei use their main means of scoring,positive and negative strong counterattack,and to backhand-based,then serve the score after the first episode has increased.However,through the video game can be seen Kei Nishikori in the face of Djokovic and Murray's changing serve,it would seem underestimated,unable to do anything.(3)Phase ball phase,the total winning points,Nishikori Kyi averaged 2.9 points per game higher than his opponent,but in the short-term stalemate Nishikori did not have the advantage and slightly more unforced errors In opponents,the score before the net rate higher than the opponent,and the utilization rate showed an upward trend,the success rate of breakage,Kaneshiro Kei and not able to grasp the opportunity to show that Kaneshiro Kei key points in the treatment is not enough Calm,can not grasp the key points of opportunity.(4)Through factor analysis,each factor score function was obtained.According to the data,the scores of each factor were calculated and it was found that Nishikori had a large gap between the stability factor,serving factor,and key factor and the opponent.There is slightly more advantage than the opponent.NishikoriKi as a representative of Asian players,through his analysis of skills and tactics,has also made some inspirations to the development of men's professional tennis in China.For example,due to the congenital conditions such as height and weight,the Chinese players and even Asian players can hardly send powerful and fast serve.We have seen that in the top few athletes in the world,Nishikori Kyoko has a low speed of serving,but we can use the ball's rotation and drop points to create trouble for opponents.Guarantting the success rate of the serve and reduce the mistakes of the two sides.Perfecting their composition of service techniques and appropriately increasing the frequency of use of cutting balls can disrupt the rhythm of opponents' shots and earn sufficient preparation time for themselves.In the stage of receiving the service,to give full play to the advantages of flexible footwork,strengthen targeted training for receiving the ball,make a good judgment on the serving of the opponent,and have sufficient preparations.In the phase of holding the ball,increase the batting stability training and reduce their unforced errors.Strengthen psychological quality training and improve the ability to handle key points.
