Research On The Application Characteristics Of Defensive Counter Attack Tactical Systems At Chinese And Foreign Women Beach Volleyball Players

Defensive counter attack tactical systems is one of the main points in the beach volleyball tactics.In beach volleyball,it is impossible to get the final victory without defensive counter attack tactical.With the development of beach volleyball,its techniques and tactics have formed a relatively complete system from the isolated and dispersed state.In the game,the player's responsibility has changed from a single attack or defense to a combination of attack and defense and more comprehensive ability.Every excellent player should have the dual function of attacking and defending,and it is far from enough to use the experience of indoor volleyball division of labor as a clear defensive tactic.Therefore,the defensive counter attack tactical system occupies a more important position in the match.On the basis of reading the literature,this paper adopts the expert interview method,the questionnaire survey method and the Daphne method to determine the dimension of the research index,and uses AMOS software to construct the structural model of the beach volleyball defensive counter attack tactics system.The fitting degree of its structural model can meet the research needs of its application characteristics.Therefore,every tactical index is analyzed in detail,and literature,mathematical statistics,comparative analysis and so on are used in the paper analysis.This paper summarizes the application characteristics of defensive counter attack tactical system of beach volleyball women athletes.This paper compares the forms and effects of defensive counterattack tactics used by strong women beach volleyball teams at home and abroad,and analyzes the advantages and disadvantages of the defensive counter-attack tactics in the course of the competition.The results are as follows:(1)The structure Model used in the defensive counter attack tactical system of Beach Volleyball is divided into two internal structures: blocking and counterattack.The link of blocking is divided into two kinds of operational characteristics:blocking and withdrawing.The counter attack links are divided into three types:attacking position,attacking mode and attacking type.The evaluation index of each adaptation parameter of the structural model reaches the basic standard,and the adaptability of the model is good.(2)The characteristics of tactics used in blocking and defending links shows that the tactics of blocking and withdrawing are the most important characteristics of tactical application in blocking and defending links.The significant difference between tactics is due to the coordination of front and rear defense,especially the backward running defense coordination.the success rate of withdrawal tactics is better than that of blocking tactics,which indicates that the judgment of withdrawal time is relatively reasonable,and the difference is not big.But in blocking scoring rate,foreign combination advantage is obvious.(3)The characteristics of tactical application in the adjusting and attacking links shows that the deadweight and high ball tactics are the most important characteristics of the tactical application in the tweaking and attacking links.The reason for this is that the heavy and high-ball tactics are still the safest and most threatening in counter-attack.The characteristics of counter attack position are not obvious.The scoring point is mainly in the back court,but in the middle and front court,there is a significant difference in the scoring point,which is due to the difference of offensive mode and type of use tendency.However,there is no significant difference between the two in the overall score of counterattack.
