Abstract
The purpose of this study was to clarify the problems of regional collegiate women’s doubles tennis by focusing on the point acquisition and the last shot of a rally. Total number of the subjected matches were thirty and categorized as the world tour, the national collegiate tournament, and the regional collegiate tournament. All the matches were held in hard court and 3-tiebreak sets. We tagged all the matches by SPLYZA Teams (SPLYZA Inc.). We calculated point winning rate by server (receiver), the frequencies of rally numbers, the ratio of the last shot, and the last shot player ratio when the rally finished by net play. As a result, the point winning rate showed high on the 1st serve. Especially, the last shot ratio of the return showed high on the world tour category. The last shot ratio of net play showed low on the regional collegiate tournament. When the rally finished by net play, the ratio of the partner of the server or the receiver showed high on the last shot player ratio. Those results insisted the problems of regional collegiate women’s doubles tennis were the techniques of serve or return and the net-play for the positional role of the partner of doubles team.
