| In order to find the gap between the Chinese and foreign defenders and to improve the training and competition ability of the Chinese defenders,the RSR method,the literature method,the video observation method and the expert interview method are combined with the 2017-2018 CBA playoff 32 games.The conventional statistical indicators of basketball games are used to analyze the offensive and defensive capabilities of Chinese defenders and foreign aid defenders.The results are as follows:(1)The average RSR of the Chinese defender's offensive ability is 0.376,the average RSR of the defensive ability is 0.362,and the average RSR of the offensive and defensive ability is 0.356;the average RSR of the foreign aid guard's offensive ability is 0.625,the average RSR of the defensive ability is 0.605,and the offensive and defensive ability.The average RSR value is 0.605.The data shows that the Chinese defenders have weaker offensive and defensive capabilities than the foreign aid guards.(2)In terms of offensive ability,the top 8 of the offensive RSR value ranking table are all foreign aid guards.In the comparison of indicators,there is no significant difference between the domestic defender and the foreign aid defender in shooting percentage and offensive rebound(P>0.05).Regardless of high or low,the data difference between Chinese and foreign defenders was significant(P<0.05),and the foreign aid advantage was obvious.The domestic defender only has fewer turnovers per game than the foreign aid,and the reason is related to the fact that the Chinese defender has a short playing time and a small holding time.The statistical data combined with qualitative analysis believes that the main problem in the local defender's offense is that the scoring method in the Chinese defending game is relatively single,mainly relying on the mid-range shooting score,and the personal breakthrough ability is weak,especially in the process of breaking through.Mistakes,the chances of the three-point shot in the game are not determined enough,the position of the activity is relatively small,the purpose of the offense is unknown,and the chance of passing the assist is not timely.(3)In terms of defensive ability,among the top 8 players in the defensive RSR ranking table,the local defender has only one player,the defensive RSR value is 0.52,which is ranked fourth in the B level,and the remaining Chinese defenders are all outside the 8th.Among them,the defensive rebounding foreign aid advantage is obvious,the Chinese and foreign defender defensive rebound cricket index value difference is significant(P <0.05),the remaining indicators foreign aid guard and domestic guard data gap is not very large,there is no significant difference,but the foreign aid guard overall The defensive ability is higher than that of the Chinese defender,so the foreign aid ranking in the defensive ability RSR ranking table is overall higher.Data combined with qualitative analysis,the main problem in the defense of the local defender is that the rebounding awareness is not strong,the judgment is not accurate,and the action is not active enough.(4)In terms of offensive and defensive comprehensive ability,the foreign aid guard ranked first in the Beijing team's Jackson,the RSR value was 0.67,and the Chinese defender's attack and defense ability RSR value ranked first for the Zhejiang team's Lin Zhijie(Taiwanese player),RSR value of 0.43 It is in the sixth place of the overall attack and defense ability B level,and the remaining Chinese defenders' comprehensive ability level of attack and defense are in the C to D level.Conclusion: In the 2017-2018 season,the body shape of the top eight teams in the CBA League is comparable to that of foreign aid.In terms of playing time and scoring average,the difference between the top 8 team defenders and foreign aid is obvious,and the role of the local defender is weaker than that of foreign aid.In terms of offensive ability,the league's top 8 team guards are weak,the offensive RSR is low,the scoring method is single,the number of offenses is many,and the assisting ability is insufficient.In terms of defensive ability,the main gap is the competition.Insufficient defensive rebounding ability;overall RSR offensive and defensive ability,the overall advantage of foreign aid is obvious,the ranking is high,and the top 8 team guards are in a low-level offensive and defensive equilibrium.Among them,the lack of offensive ability is the reason why the top 8 team's offensive and defensive ability ranking is more important.Suggest: First,we must cultivate the self-confidence of the local defenders.Do not rely too much on foreign aid in thinking.We must have training plans and arrangements that the defenders improve year by year,and cultivate the awareness that the local defenders dare to take responsibility.The attack is attacked,the vote is voted,and the opportunity should not hesitate.In order to continuously improve the self-confidence and personal ability of domestic defenders.Second,it is necessary to specifically improve the actual combat capability of the defender and strengthen the comprehensive training of the technology.The local defender has a higher attack success rate in the face of weak defense.Once the defensive intensity is improved,most local defenders lose the ability to hold the ball.For this reason,the actual combat training should be strengthened to improve the player's offensive stability in a complex defensive environment.Sexuality,cultivating guards in the face of high-intensity defensive daring and daring awareness,improving the ability to use shooting techniques and anti-interference shooting ability in defensive interference.Third,physical training and core strength training should be strengthened.Physical training is an important part of modern basketball training.Without physical strength and core strength training,there is no basis for physical confrontation and technical application,which will lead to a dilemma of defensive difficulties and weak offense.Comprehensively strengthening physical training is not only an important channel to enhance the strength of domestic defenders' offense and defense,but also an important measure to reduce unnecessary fouls and mistakes.Fourth,we must focus on improving defensive weaknesses.To change the domestic defender's habit of only retreating to rebound and rebounding,on the basis of paying attention to the balance of offense and defense,the personnel who fight for rebounding should be increased.The defender should have a positive attitude and willingness to fight for rebounding.On the other hand,Advance the placement in advance and seize the favorable position in time,which is an important way to improve the ability to rebound.Fifth,to improve the offensive and defensive ability of the players,the ability of a good defender is not only reflected in the offensive aspect,but also on the defensive.The imbalance between offense and defense is ultimately the embodiment of the ability defect.No matter whether it is "strong or weak" or "strong and weak",it has limitations.It can only become a role player.In the important time of important games or competitions,there will always be a team.Cause difficulties or injuries.Therefore,it is necessary to train domestic defenders to develop in a comprehensive,high-level balance of offense and defense.Six should pay attention to "nearby" learning and improvement.Chinese defenders and foreign aid defenders are both opponents and teammates.Mastering foreign excellent skills and tactics,although you can select some young players with potential to learn,train,and improve in other countries,not everyone has such an opportunity.In the domestic channel through the club to "please come in" foreign aid,it is also possible to improve the training level and ensure the advanced nature of training.The Chinese defender should cherish the opportunity of "nearby" learning.To sum up,only through targeted training,short-boarding,and development of comprehensive capabilities can we improve the offensive and defensive strength,offensive and defensive levels,and overall strength of Chinese defenders.Clubs,athletes,and coaches should pay attention to this. |
