2014年全國(guó)男子青年籃球聯(lián)賽前八名位置效率的統(tǒng)計(jì)研究
[Abstract]:The present basketball technical statistics do not reflect the difference between positions and the efficiency of the players in the game. This study is based on the original technical statistics to increase the difference between the positions and the efficiency of the players in the game. The research is based on the actual effect of the technical and tactical offensive and defensive ability of a team in the same position in the unit time, which can be approximately quantified as the ratio of the contribution value of the player in the same position to the number of matches, that is, "position efficiency". It has a high reference value for measuring the ability performance and potential ability mining of players in different positions. To provide a more adequate theoretical basis for sports material selection. This study uses the method of literature, video observation, mathematical statistics and comparative analysis to analyze the top 8 teams of the 2014 National Youth League by using the statistical method of location efficiency. The validity and feasibility of the statistical method to check the location efficiency. The ultimate goal is to provide reference for the formation and transformation of different types of teams and the medium-term selection. The research results show that: (1) the ranking of the top 8 matches in the 2014 National Youth League is linearly correlated with the total ranking of each position efficiency. (2) by analyzing the structure of the top eight teams in the 2014 National Youth League, There are three basic types of Chinese basketball youth team: strong front / guard; Strong center front type; three-line equilibrium type. Among the top eight teams, Xinjiang, Guangdong, Beijing, Zhejiang, Shanghai belong to the strong front / guard type, Dongguan is the three-line balanced type, August 1, Shandong belongs to the strong center type. This and each team three position presents the position efficiency characteristic also basically similar. At the same time, we can also see the advantages and disadvantages of each team position, which provides a valuable reference for training and match tactical arrangements. (3) through technical analysis and comparison of youth team location efficiency performance: coefficient of variation (CV), center 73.1, Forward 38.37 and defender 40.44, which shows that the efficiency of center position is relatively large, and the difference between guard and forward is small (Table 7). This shows that the team's strength gap in the center of the position than the forward and the defender. Our youth league should pay attention to the position of center in selection and training.
