[Purpose] This study clarified differences in players' contributions to the team's score in female wheelchair basketball at the 2016 Rio Paralympics by physical capacity classification, and examined the roles required in the team. [Subjects and Methods] This study used stats (record of play contents) for players who played for more than 20 minutes from the official box scores of all 31 games at the 2016 Paralympics. Players were divided into three groups by physical capacity classification: low, middle, and high. The average stats for each group were compared and the covariance structure was analyzed to determine the role of each group during the game. [Results] Comparisons showed that the higher the class, the higher the value of many stats items. Important elements were defensive rebound, steal, and turnover in the low group; and score, offensive rebound, and turnover in the high group. [Conclusion] Players in the high group have more plays related to the ball. Those in the low group should increase the numbers of steals and defensive rebounds and reduce turnover. High group players are required to have scoring ability, acquire offensive rebound, and reduce turnover.
[目的] 本研究通过体能分级阐明了2016年里约残奥会女子轮椅篮球比赛中球员对球队得分贡献的差异，并考察了球队中所需的角色。[对象与方法] 本研究使用了2016年残奥会全部31场比赛官方比赛成绩表中上场时间超过20分钟的球员的统计数据（比赛内容记录）。球员按体能分级分为三组：低、中、高。比较了每组的平均统计数据，并分析了协方差结构以确定每组在比赛中的角色。[结果] 比较表明，分级越高，许多统计项目的值越高。低分组的重要因素是防守篮板、抢断和失误；高分组的重要因素是得分、进攻篮板和失误。[结论] 高分组球员有更多与球相关的表现。低分组球员应增加抢断和防守篮板次数并减少失误。高分组球员需要具备得分能力、获得进攻篮板并减少失误。
