左撇子网球选手在顶尖选手中占比更高，或具战术优势。
Left-handed representation in top 100 male professional tennis players: Multi-disciplinary perspectives
- 分析ATP排名前100球员数据，发现左撇子占比约15%。
- 显著高于一般男性左撇子比例（约10%），存在过代表象。
- 适合教练、家长及赛事分析者参考选材与战术策略。
普遍认为左撇子网球选手在精英群体中占比高于其在普通人群中的比例。本研究基于1985至2016年ATP官网数据，对排名前100的男子职业网球选手进行分析，发现左撇子选手占比约为15%，显著高于一般男性左撇子约10%的比例，显示出明显的过代表象。该结果可为父母和教练在无明显左右手偏好时决定孩子是否练习左撇子打法提供依据，有助于提升训练策略、赛事分析、媒体传播及装备研发的科学性。
原文摘要 · Abstract (English)
A commonly held opinion is that left-handed tennis players are overrepresented compared to the percentage of left-handers within the general population. This study provides the domain insights supported by data analysis that could help inform the decision of parents and coaches considering whether a child should start playing tennis as left- or right-handed when there is no strong arm-handed dominance. Compared to the commonly cited figure of about 10% of left-handed male population, data analysis from the official ATP web site for the top 100 ranked tennis players over the past decades (1985-2016) shows evidence of overrepresentation of left-handed elite tennis players (about 15%). The insights and data analysis can inform the handedness decision, advance coaching and strategic game concepts, enhance media coverage/analytics, left-handed facts and statistics, and inform tennis equipment manufacturing.
