This study analyzed whether a ball with a higher (540-g) or lower (440-g) mass than the regulation ball (485-g) resulted in a larger number of participants gaining ball possession during games. Prior studies have indicated that ball handling is facilitated by decreasing the mass of the ball. It was assumed that a greater number of children gaining possession of the ball indicated greater ease of use and more control. Thus, the hypothesis was that the number of participants who gained ball possession would increase when using a ball of lower mass. The participants were 54 boys from six youth basketball teams. Participants played four games with each one of the three different balls and the number of possessions was calculated using videos of each game. The hypothesis was only partially supported: the number of participants who gained possession with the regular ball was similar to that with the 440-g ball and with the 540-g ball, but a greater number of participants gained possession with the 440-g ball in comparison to the 540-g ball. This result suggests balls that differ by more than 65 g may affect actual game outcomes.
这项研究分析了与标准球（485 克）相比，质量更高（540 克）或更低（440 克）的球是否会导致更多参与者在比赛中获得球权。先前的研究表明，通过降低球的质量可以更方便地处理球。研究假设，更多的孩子获得球权表明球的易用性和控制能力更强。因此，假设是使用质量较低的球时，获得球权的参与者人数会增加。参与者是来自六个青年篮球队的 54 名男孩。每个参与者用三种不同的球各玩四场比赛，并通过每场比赛的视频计算控球次数。该假设仅得到部分支持：使用标准球和 440 克球获得控球权的参与者数量与使用 540 克球获得控球权的参与者数量相似，但与 540 克球相比，使用 440 克球获得控球权的参与者数量更多。这一结果表明，质量相差超过 65 克的球可能会影响实际比赛结果。
