Therefore, center-forwards' function appears prominently. The center-forwards'technical level is playing the pivotal role to the entire team's level and even the competition victory and defeat. Our country men's basketball team can sit quietly the highest post in Asia, as soon as even also may struggle high at the international big game with the world strong team under, is because we have world-class apex center Yao Ming to be bright. Although the present esteems the overall tactic and advocates the entire team tactic coordination which has become the development mainstream of each European and American strong teams and NBA league tournament tactic thought , the attack emphasizes the whole coordination, defends emphasizes joint defense ,the position concept is more and more fuzzy, but center-forwards'technical level is still the important target which weighs the entire team technique and tactics level and the decision of competition victory and defeat. The center-forwards strength height manifests one of team level important symbols.From the ornamental angle, the market operation, the influence or the player synthesizes the strength to look NBA ,which is the highest professional basketball league tournament in the world, US is also the most attractive country which introduces basketball outstanding talents, whose collection various countries ball game stars, the basketball athletics competition has become the American important humanities landscape and the sports industry, without a doubt, US is now the first powerful basketball nation in the world.

May say the NBA outstanding center-forwards'level has represented the world basketball center-forwards'maximum level. Our basketball league tournament CBA which represents our country basketball most high level is not lack the outstanding bodily condition also the synthesizing capacity stronger center players. Three outstanding center-forwards Wang zhizhi, Yao Ming, Batter who are trained by CBA after 2001 successively is selected by NBA, by the reputation for"China's moving the Great Wall". But objectively speaking to compare the majority CBA center-forwards with the NBA center-forwards, the former still have very much deficiency. This paper based on the CBA center-forwards and the NBA center-forwards technical level existence disparity, take 2005-2006 season CBA and the NBA outstanding center-forwards as the research object, take various centers players' attack technical specification, the defense technical specification and with the technical level correlation factor as the research target, use literature material law, questionnaire survey law, scene and video recording observation law, mathematical statistic law and logical analytic method, thorough comprehensive research CBA center-forwards and the NBA center-forwards technical level exists the disparity and proposes the countermeasure, to raise the CBA center-forwards'technical level and the CBA league tournament competition level, and even to enhance our country basketball the overall level to provide the science the reference. Findings as follows: 1.CBA center-forwards equally are 26.3 years old, the NBA center-forwards'average age is 29.3 years old, differs 3 years old, the NBA center-forwards obviously are higher than the CBA center-forwards. The CBA center-forwards and the NBA center–forwards'time on the stage all above 35 minutes, that is to say regardless of in CBA or NBA, the center-forwards all occupy the most important status in various teams' tactic systems. The center-forwards always pass through the entire competition fields, regardless of from defend and the attack angles center-forwards all are the important weights of the wined teams. The findings indicates that, in the height, the body weight, the gram request BMI comparison aspect the two did not have the difference, the CBA center–forwards basically have already met the world outstanding center's good bodily requirement.2. CBA center-forwards two divides the ball hit probability and scores points are higher than the NBA center-forwards, explained the CBA center-forwards'way of two point balls score points is effectively, shooting movement is stable, the hit probability is higher, but this kind of phenomenon and the CBA player individual defense ability is worse, the whole defense level lowly has the very big relations. The CBA center–forwards attack the backboard more than the NBA center-forwards, explained CBA center-forwards when attack flushes snatches the attack backboard consciousness strongly, and the companions shoot the ball point of descent assurance after oneself to be more accurate. The NBA center-forwards secondary attack is higher than the CBA center, the NBA center's coordinate consciousness, the quality of catching balls aspect surpasses the CBA center.3. Through the comparison with the defend technical level of CBA and the NBA outstanding center-forwards we can find that: The CBA center-forwards defend the backboard accounts for the proportion in the backboard total to be smaller than the NBA center-forwards (the CBA center-forwards are 64.9%, the NBA center-forwards are 74.7%), explained the CBA center-forwards also have the certain disparity in the defensive backboard protection. The CBA center-forwards'level of putting on a cap is lower than the NBA center-forwards, but the CBA center-forwards snatch and break the ball technology, assures the opportunity of attacking the team member to pass a ball more strongly than the NBA center-forwards. To compare with the CBA center-forwards and the NBA center-forwards, CBA center-forwards are making up guards against the harmonious cooperation and guard against consciousness aspects which have the certain disparity.In conclusion, through CBA and the NBA outstanding center-forwards technical level and the correlation factor comparison research was allowed to see the CBA center-forwards to meet the world outstanding center body requirement, but also have the certain disparity in many aspects of technical level. This kind of disparity is not merely the center technical level disparity, but also manifests the CBA league tournament and the NBA league tournament overall attack and defense system, the tactical thought, the training equality various disparity, Therefore, to raise the CBA center-forwards'technical level have to begin from the multi- positions, the three-dimensional angles, follow the basketball development tendency, discover the disparity from the contrast, solve the problem in the practice, thus causes the CBA center-forwards technical level and the CBA competition level and the watching realization quantities leap.
