The Statistical Research To The Man’ Position Efficiency Of The Top Eight In The 2014 National Youth Basketball League

Today’s basketball statistic does not reflect the differences between each position and the efficiency of the players in the game, the study is based on the original technical statistics which now increases the differences between each positioon, as well as the efficiency of the players in game. This research reflects their technical, tactical and actual effect of offensive and defensive ability on per unit time in the same position on the same team.Which can be approximately quantitative for the same position players contribution value and the ratio of games, it is "efficiency position”. It has higher reference value to measure the ability of different position player performance and potential mining 。 To provide more adequate theoretical basis for sports talent selection. This study adopts the method of literature study, video observation, mathematical statistics, comparative analysis, By using the location efficiency statistical method to analyze the 2014 national youth league’s top eight teams,Inspect the effective and feasible of the location efficiency statistical method. The ultimate goal is in form of different types of teams for the future reform and medium-term materials that provids a reference basis.Research shows that:(1)The 2014 national youth league’s top eight grades ranked the each locations efficiency and rankings of the combined ranking.(2)Through the analysis of the 2014 national youth league’s top eight team structure and the basic three types including:emphasis of front and guard;strength center type;Three line equilibrium。In the top eight teams,xinjiang, guangdong, Beijing, zhejiang, Shanghai belong to the strong front,Dongguan is the three line equilibrium type, Eight one, Shandong is a strong center type 。 It’s similar characteristics with the teams of three position rendering efficiency。(3)Through technical analysis location efficiency of the each youth teams:Coefficient of variation(CV)shows,ceter forword 73.1%,forword38.37%,guard 40.44%,Shows the efficiency of the center forwords’ differences degree is relatively large,guard and forwards’ differences degree is small(form7)。This suggests that teams ‘ degree of the strength of the gap in the center is bigger than forward and guard.
