Performance analysis in tennis since 2000

In tennis, performance analysis has advanced primarily as notational analysis. And analytical techniques markedly advanced, particularly in the fields of notational analysis and match analysis. In tennis, the Hawk-Eye system was introduced to tour tournaments in 2002. It has recently become used for player tracking and post-match analysis, there are a number of papers using Hawk-Eye data. Along with the development such measuring devices, technologies for analysis of a vast amount of data collected with these devices (big data) have also been developed. In particular, analysis by machine learning using AI was developed in the field of engineering, and it is also increasingly adopted in the field of sports. In the present review, we aimed to clarify the direction of research on performance analysis of tennis by organizing the trend of studies of performance analysis after 2000 with particular attention to the methods of data collection in the hope of furthering the development of this field. As a result of search of reports concerning performance analysis of tennis published after 2000 with particular interest in data collection methods, 90 papers were retrieved. The papers were classified into primary and secondary data collection, and subclassified into six categories, i.e., tracking, video recording, data mining, observations of coaches, websites, and broadcasting. This review of the papers in different categories may aid in developing future directions of research in the field of performance analysis in tennis.
