NBA "Position Ambiguity" Research Players

Research through the collection,inspection,sorting,and summarize large amounts of data on "position ambiguity" theoretical concept,as well as the theoretical basis for the development of a systematic grooming;study to the 2007-2008 season, NBA "position ambiguity" player's age,height,weight,g reliable and the technology index is based on statistical indicators,such as the use of methods of mathematical statistics,the NBA "position ambiguity" age,height,weight,Quetelet index to analyze and understand the world's top basketball league "position ambiguity" of the physical form of the players characteristics of the location of fuzzy statistical analysis of the technical players and players with the traditional location of the technology a comparative analysis of statistical indicators in order to clear the NBA "position ambiguity" of the technical statistical characteristics of the players;in the above analysis,based on the use of factor analysis,to establish a "position ambiguity" of the competitive performance of the players-factor model,the model based on further analysis of "position ambiguity" performance characteristics of competitive players.The study concluded that:(1) "position ambiguity" of the development is a gradual process,and "position ambiguity" has become a modern basketball development.(2) of the 2007-2008 season,NBA has a "position ambiguity" 144 players,which guard/forward player 73,and forward/center 71 players,guard and center due to limited height and location of the technology gap,but also the location of the division of labor can not be completely broken a "position ambiguity" players.(3) players,compared with the traditional position,"position ambiguity" players age and body shape has its own characteristics.(4) the technical characteristics with the advantages of two-position,but in the process of attack and defense also have their own limitations.(5) guard/forward from members of the athletic performance of the three common factor,that is,a comprehensive skill factor,the air pushing against the factor, one-third of the performance factor to reflect the integrated,which assists and field values are the highest scoring load that as a good guard/forward player,must have strong organizational skills and offensive capabilities;forward/center players from the competitive performance of the three common factor,that is,a comprehensive skills factor,team factor,psychological factor to the stability of the integrated embodiment,in which rebounds maximum value of the load that is rebounding forward/center the most important responsibilities of the players.
