Analysis Of The Characteristics Of Nadal's Use Of Techniques And Tactics On Clay Courts From 2010 To 2018

In this paper,through the application of research methods such as literature data method,video observation statistical method and comparative analysis method,the technical and tactical use of Nadal 2010-2018 red clay venues is taken as the research object,and the technical and tactical characteristics are statistically analyzed.The following conclusions are drawn:Serve attack stage: Nadal's first serve in the three periods of the three divisions is more uniform,both inner angle>middle road>outer angle;the selection tendency of the third period of the second division of the flat section is quite different,2010-2013 The annual period is the middle road > the inner angle > the outer corner.During the period from 2014 to 2016,the angle serve and the middle serve are equal,but the usage rate of the outer corner serve is less than 5%.The period from 2017 to 2018 is the inner angle > middle road > outer corner.The use rate of the first serve line in the pre-emption area was different in three periods.The first two periods were the most outer corners,while the third period had the most angle selection,followed by the outer corner,the middle road served the least;the second serve line in the pre-emption area.The usage rate is the most in the middle of the three periods.It can be seen from the serve that the strong area of the Nadalping division is the inner corner and the preemption area is the outer corner.The third-hand forehand hitting rate was 79.9% in the 2014-2016 period,while the backhand hitting rate was only 17.6%.The difference between the two was quite different;2010-2013 and 2017-2018 The forehand usage rate of the two periods was 71.0% and 66.9%,and the backhand hitting rate was24.9% and 28.7% respectively.The use rate of the opponent's backhand position was the least in all three periods.And it is on a downward trend.Receiving the ball attack phase: the second shot(that is,receiving the serve)the use rate of forehand shots is slowly increasing,from 43.9% in the 2010-2013 period to 57.5% in 2017-2018,and The usage rate of backhand hair extensions is always around 50%.In the line selection,the opponent's use rate of the hand gradually increased from 34.0% in the first period to 42.2% in the third period,and the usage rate of the opponent's backhand position decreased from 45.5% to 41.0%.The usage rate of the fourth-shot forehand hitting technique showed a downward trend,and the backhand hitting the ball was on the rise;the choice of the line was dominated by the opponent's backhand,showing an equal development trend.The phase of stalemate: Forehand and backhand techniques occupy an absolute position in three periods.The forehand usage rate is higher than the backhand,but thegap between the two is gradually narrowing.The success rate of forehand shot is slightly higher than the backhand.The success rate of backhand shots is rising,indicating that Nadal's backhand technology stability is constantly improving;in the choice of lines,the opponent's backhand and middle road usage rates are on the rise,and the opponent's forehand position is on a downward trend.
