Previous studies about tennis performance analysis in Chinese only provided technical data, but paid little attention to the court positioning data. As a result, the issue of the court positions between players in tennis doubles needs to be addressed. Purpose: The present study explored the use ratio and scoring efficiency of skills and court positions tactics about elite women’s tennis doubles competition. Besides, the association between hold or broken games, and the service performance was also investigated. Method: The skills of serve, return, volley, ground stroke and the results of per shot through 15739 data from 24 videos of tennis matches from quarter-final to final about Australian Open and US Open between 2016 to 2019 were recorded. Besides, the number of occurrences about five types of court positioning tactics, which were determined in units of three strokes, including the basic, aggressive, defensive, defense-turning-attack, and forced defense, as well as the effects of skills were also recorded. The chi-squared tests of fitness and the chi-squared tests of independence were used for data analyses. Results: Results showed that ground stroke was used the most and volley was used the least but the latter got more scores. There were more 1st serves and ACEs in the serve-holding games whereas more 2nd serves and double faults were observed in the serve-breaking games. Although the court positions of one up and one back were used the most in the games, it was the two ups that had the highest scoring rate. The court positions of the two backs had the highest rate of rally continuation. For the court positioning tactics, the basic type had the highest rate of occurrence, the aggressive type had the highest scoring rate, and the defense type and forced defense had the highest rally continuation rate. In summary, the results from the present study provide the performance trends of elite professional women’s tennis doubles and may be used as bases for training program in practice. Further research is needed to provide more accurate variable definitions and apply to different match levels.站位模式比賽表現分析得分效益court positioningperformance analysis in sportscoring efficiency
