| Outline of Final Research Achievements |
TThe purpose of this study was to explore the effectiveness of table tennis services in real matches of competitions, focusing on the rotation of the ball and the swing. In particular, the rotation speed of service balls (rotations per second: rps), the swing motion of services, and the number of shots played per rally (the sum of a correct service and correct returns) were measured in competitions at three different levels: world, Japanese, and local. From the results, it was suggested that the effectiveness of table tennis services was determined not only by the magnitude of the rotation speeds, but also by the degrees of skill of feint motion when making different spins on the service ball.
