RSOS_Supplementary Material_TableS1 from Prevalence of left-handers and their role in antagonistic sports: beyond mere counts toward more in-depth distributional analysis of ranking data

Table S1 Prevalence of left-handed athletes. Frequencies of left-handed female and male athletes listed in the top-300 of year-end world rankings between 2004 and 2023 for fencing (épée, foil, sabre) and interactive ball sports (table tennis, tennis, badminton). Variation in left-hander frequencies was assessed across high, medium, and low ranking groups using ranking intervals of 100 (ranks 1–100 vs. 101–200 vs. 201–300), and 50 (ranks 1–50 vs. 126–175 vs. 251–300). Results from χ² goodness-of-fit tests compare left-hander frequencies among athletes with those of left-handers in the general population (females: 9.5%; males: 11.6%; Papadatou-Pastou et al., 2020).

附表S1 左利手运动员占比情况。本数据集收录了2004年至2023年间，击剑项目（重剑épée、花剑foil、佩剑sabre）以及隔网对抗球类运动（乒乓球、网球、羽毛球）年终世界排名前300名的男女左利手运动员的占比数据。本研究以100名跨度的排名区间（第1-100名、101-200名、201-300名）与50名跨度的排名区间（第1-50名、126-175名、251-300名）为划分依据，将运动员划分为高、中、低三个排名组别，以此分析左利手占比的分布差异。通过卡方拟合优度检验（χ² goodness-of-fit test），将运动员群体的左利手占比与普通人群的左利手占比（女性：9.5%；男性：11.6%；Papadatou-Pastou等，2020）进行对比分析。
