While left-handers have been overrepresented among 7-meter shooters in handball, previous investigators have not found success from the 7-meter line to be related to handedness. Drawing on previous handedness research in sport, we performed two studies to examine possible negative frequency-dependent advantages to left-handedness during 7-meter throws among elite players. In Study I, we analyzed the records of 974 7-meter shooters from Danish and Norwegian elite divisions (485 males and 489 females) and found that left-handed males were overrepresented compared to the prevalence of left-handers in these two leagues, but left-handed females were not. An analysis of covariance showed no statistically significant associations between throwing arm or sex, and success from the 7-meter line. In Study II, we analyzed the records of 899 7-meter shooters at 41 major championships for both males and females between 2007-2023 (442 males and 457 females). We again found left-handed males to be overrepresented compared to their prevalence at the championships, but left-handed females were not. Also, in alignment with Study I, an analysis of covariance found no associations between throwing arm or sex, and success from 7-meter throws. These findings further underline the complexities associated with lateral biases in sports, where there appear to be benefits for left-handed males in the selection process that are not evident during performance execution.
虽然在手球 7 米射门手中惯用左手的人比例过高,但之前的研究人员并未发现 7 米线的成功与惯用手有关。借鉴运动领域的先前惯用手研究,我们进行了两项研究,以在手球精英运动员的 7 米投掷中检查惯用左手可能存在的负面频率依赖性优势。在研究 I 中,我们分析了来自丹麦和挪威精英联赛的 974 名 7 米射门手的记录(485 名男性和 489 名女性),发现与这两个联赛中惯用左手的比例相比,男性惯用左手的人比例过高,但女性惯用左手的人比例则没有。协方差分析显示,投掷臂或性别与 7 米线的成功之间没有统计学上的显著关联。在研究 II 中,我们分析了 2007-2023 年间 41 项重大锦标赛中 899 名 7 米射门手的记录,包括男性和女性(442 名男性和 457 名女性)。我们再次发现与锦标赛中的比例相比,男性惯用左手的人比例过高,但女性惯用左手的人比例则没有。同样,与研究 I 一致,协方差分析发现投掷臂或性别与 7 米线的成功之间没有关联。这些发现进一步强调了与运动中侧偏优势相关的复杂性,在选拔过程中,男性惯用左手似乎存在优势,但在表现执行过程中则不明显。
