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.
