Development of Youth Tennis Players: A Study Based on the Ranking History of Top ATP/WTA Players Worldwide and China

The data for this study was mainly collected from publicly available sources, including the official ATP website (www.atptour.com), the official WTA website (www.wtatennis.com). In addition, no more than 10% of the data on the age of starting tennis were taken from Wikipedia in conjunction with the results of other web searches. The top 100 ATP and WTA ranked players have been included in the research scope. Furthermore, taking into account the limited number of Chinese athletes in the sample, two relatively high-ranking Chinese players were supplemented as research subjects. A total of 202 players` ranking information was used for analysis.

本研究的数据主要采集自公开可获取的数据源，包括ATP（Association of Tennis Professionals）官方网站（www.atptour.com）与WTA（Women's Tennis Association）官方网站（www.wtatennis.com）。此外，网球起步年龄相关数据中占比不超过10%的部分取自维基百科，并结合了其他网络搜索结果。本研究的研究范围涵盖ATP与WTA排名前100的选手。此外，考虑到样本中中国运动员的数量有限，补充了两名排名相对靠前的中国选手作为研究对象。最终共有202名选手的排名信息用于本次分析。
