In recent years,with the continuous development of the Women's Chinese Basketball Association,many excellent professional basketball players from Europe and America have joined the WCBA,which makes the WCBA more ornamental and confrontational.Ba-Yi Team is a domestic famous old brand in the WCBA league,and it is also the unique professional military basketball team.The team has been famous for its tenacious style,excellent technical quality and hard-working spiritoriginatin from the army.How to give full play to the strengths and advantages of local players,and how to use the overall defensive tactics to restrain the strong attack and breakthrough of foreign players and maintaining a good tradition at the same time,have always been the focus of maintaining a good competitive state while insisting on not importing foreign players.Especially in the2017-2018 season,the sudden decline in the performance of Ba-Yi Women's Basketball Team has aroused additional attention.Therefore,this article takes the Ba-Yi Women's Basketball Team as the research object,and uses the methods of literature review,video analysis,survey method,case analysis,mathematical statistics,logic analysis and other research methods.Through the analysis of Ba-Yi Women's Basketball Team's individual body shape and age,using of position defense and it effects,and defensive efficiency value of each location while using positions defense in 2017-2018 season,demonstrates the rationality and effectiveness of defensive tactics from these three aspects,and draw the following conclusions:1.The body shape of the players of Ba-Yi Women's Basketball Team is in a dominant position among all the participating teams,with reasonable age structure and plentiful physical strength.Many of the main players are members of the national team,with excellent personal skills,tactics,and rich competition experience.In the competitions,they can make full use of their own special skills,give full play to their physical advantages,maximized mutual coordination and coordinated tacitly,and be consistent in thoughts and actions.To ensure that the whole defensive tactic is executed to the extent required and to disrupt the opponent's offensive intent or cause its offensive errors.2.Ba-Yi Women's Basketball Team's players have defensive advantage: the large area of control.Northern teams have strong confrontation ability and tough style.This style bases mainly on interior-line attack,under-basket attack,and overall strategy is ‘attack leads defense'.In addition,the southern teams have weak confrontation ability and attack mainly from outside.They often play outside breakthrough,break-and-pass and fast break.The overall strategy is ‘defense promotes attack',highlighting the attack characteristics of small,fast,clever and accurate.When using the same defensive strategy,the effect of defending the northern teams is obviously better than that of the southern teams.3.In the defense against fast break,with two or more players,Ba-Yi Women's Basketball Team can give full play to the advantages of multi-person cooperation while using front court‘3 on 4' or‘4 on 5'.Force the attacking team to make mistakes of fast break or change the tactic to position attack.The defense effect of ‘1 on 1 fast break' and ‘front court 2 on 3' is poor,so they need to improve ways and tactics of defense.4.When Ba-Yi Women's Basketball Team uses man-to-man defensive tactics,it often uses the half-court man-to-man defensive tactics,and uses the height and technical advantages of No.3 and No.4 positions to carry out pin-attack and assist defense against the players who attack under the basket or break through inside and outside as the main offensive means,which can effectively break down the opponent's intention of scoring directly under the basket.Use get through,chase over,go under,and switch to break up high post pick-and-rolls and off-ball screens,delay the offense,and cause turnover or ball missed.But the long-time use of man-to-man defense makes great personal physical consumption,and it is not easy to organize collective rebound.5.When Ba-Yi Women's Basketball Team uses zone defense tactic,2-3 zone defense is often chosen to destroy the offensive team's throw in from the left sideline,right sideline and the baseline,which is beneficial to reduce physical consumption and disrupt the offensive deployment,delay the progress of the game,and ensure the formation of the partly situation of power play and under the basket.But the zone defense mode is single,the tactical change is less,easy to be detected by the offensive team.6.When Ba-Yi Women's Basketball Team uses the zone press defense tactics,they often use 1-2-1-1 full-court press and 1-3-1 three-fourth court press to trap the guards and forwards' breakthrough and continuous trap.Gaining points and regaining the lead position as the main purpose through making full use of space-time advantage.Its success rate is high and the effect is remarkable.But the way of defense is relatively fixed,only applies to the center executing the free throw and or the score gap is large,and it's easy to be detected by the offensive team.7.When Ba-Yi Women's Basketball Team uses combination defensive tactics,they make the half-court man-to-man and 2-3 zone defense as the overall defensive tactics,and focus on strengthening the defensive ability under the basket,which is not easy to be detected by the offensive team,forcing the other team to change the offensive tactics and effectively controlling the speed and rhythm of the game.But the form of combination defense is single,lack of necessary tactical changes,easy to be broken by the offensive team.8.With quantitative research,the defensive efficiency value of each position of Ba-Yi Women's Basketball Team is taken as the index of individual tactical application effect in the performance of overall defensive tactics.The result of qualitative reasoning is consistent with the conclusion of defensive efficiency calculating,which indicates that the value of defensive efficiency can be used as an empirical index to evaluate individual tactics in the overall defense.
