Abstract

The purposes of this study were: 1) to measure the movement distances and the movement speeds of each player or the ball in a regular basketball game: and 2) to propose effective coaching material about players' physical conditioning through the cross-sectional comparative method of that game performance. Three basketball games were analyzed. They were the xxth All-Japan Inter-High School Basketball Championship women's semifinal (A-high school vs. B-high school in which A-high school won, 74-68), the xxth Western Collegiate Basketball Championship women's consolation match to decide third place (C-college vs. D-college in which C college won, 75-68), and the 200x-x+1 W-League Playoff Final 1st game (E-team vs. F-team in which E-team won, 98-73). In this study, the movement distances/speeds of all the players and the ball were calculated by 3-dimensional photography analysis in which the DLT method was used. Main results were as follows. 1) The average and standard deviation (S.D.) of the movement distance of all players were: high school players, 5587±171 m; college players, 5576±202 m; and WJBL players, 6177±264 m. Moreover, the average and standard deviation of the movement distance per 1 minute were: high school players, 93.4±3.1 m; college players, 100.4±4.1 m; and WJBL players, 94.2±3.5 m. 2) The average and S.D. of the fastest movement speed were: high school players, 7.03±0.51 m/s; college players, 7.41±0.26 m/s; WJBL players, 8.01±0.46 m/s. 3) From calculation of the frequency distribution for the speed ratio to the fastest movement speed, the ratio of the movement intensity in a game was high : middle : low=1 : 4 : 5. These finding revealed although the quantity of motion and movement intensity in the game did not differ much by age, each player's individual capability differed clearly.
篮球比赛中运动员与球运动距离和速度的横断面比较研究
本研究的目的是:1)测量每个球员或球在常规篮球比赛中的移动距离和移动速度;2)通过比赛表现的横截面比较方法提出有效的球员身体调节的指导材料。对三场篮球比赛进行了分析。他们分别是第20届全日本高中篮球锦标赛女子半决赛(a高中对b高中,a高中获胜,74-68),第20届西部大学篮球锦标赛女子第三名的安慰赛(C大学对d大学,C大学获胜,75-68),200x-x+1 w联赛季后赛决赛第1场比赛(e队对f队,e队获胜,98-73)。在本研究中,所有球员和球的运动距离/速度通过三维摄影分析计算,其中使用了DLT方法。主要结果如下:1)所有运动员运动距离的平均值和标准差分别为:高中运动员为5587±171 m;大学生运动员5576±202米;WJBL选手:6177±264米。每1分钟移动距离的平均值和标准差分别为:高中运动员93.4±3.1 m;大学生运动员:100.4±4.1米;2)最快移动速度的平均值和标准差分别为:高中运动员7.03±0.51 m/s;大学生运动员:7.41±0.26米/秒;WJBL选手,8.01±0.46米/秒。3)从速度比到最快移动速度的频率分布计算可知,游戏中移动强度的比例为高:中:低= 1:4:5。这些发现表明,尽管游戏中的运动数量和运动强度在年龄上没有太大差异,但每个球员的个人能力却存在明显差异。
