characteristics of defensive counter-attack tactics in each World Cup,and analyze the similarities and differences of defensive counter-attack tactics in three periods represented by three World Cups by comparison,and explore the characteristics,characteristics,changes and development trends of defensive counter-attack tactics in this period.By using the methods of literature review,expert investigation,video observation,mathematical statistics and logical analysis,this paper takes the application of defensive counterattack tactics in the regular time of 48 knockout matches in 16 consecutive World Cup finals in the 19 th,20th and 21 st consecutive years as the research object,and the overall application,general characteristics and application characteristics of defensive counter-attack tactics were statistically analyzed and compared,among which,the overall application situation included application frequency,application effect and field characteristics General features include counterattack time,counterattack passing times,and the way to get the ball right.The application features include the proportion of offensive and defensive personnel,the launching form of counterattack and the successful elements of defensive counterattack.Through the research,the following conclusions are drawn:(1)In the regular time of the 19th-21 st World Cup knockout matches,the success rate of defensive counter-attack decreased year by year,and the proportion of defensive counter-attack goals in the total number of goals decreased year by year.(2)In the regular time of the 19th-21 st World Cup knockout,the backcourt is the main launching field of defensive counter-attack,and the overall trend of defensive counter-attack success rate is frontcourt > midcourt > backcourt,but in the regular time of the 21 st World Cup knockout,the defensive counter-attack success rate is midcourt > backcourt > frontcourt.(3)There is an opportunity to use defensive

within 7-17 s in the backcourt,5-12 s in the midfield and 3-11 s in the frontcourt.The counter-attack time of the21 st World Cup knockout is mainly within 7-14 s in the backcourt,5-11 s in the midfield and3-8s in the frontcourt.Defensive counterattacks in the frontcourt and backcourt tend to get faster every year.(6)In the regular time of the 19th-21 st World Cup knockout,the passing times of defensive counter-attack are mainly 0-4 times,and the passing times of defensive counter-attack tend to decrease year by year.(7)The combination of sudden transmission is the most frequently used organization form with the highest success rate in defensive counterattack.Except the combination of sudden transmission and goalkeeper’s quick service,the proportion of other organizational forms
