| 摘要 |
An apparatus for measuring the performance of a slalom water-skier and associated methods for interpretation of the data are disclosed. The apparatus consists of a means for measuring the angle of the water-ski tow rope relative to the boat and the tension of the water-ski tow rope. This data may be transmitted immediately or stored for later transmittal. The data are analyzed by calculating the time spent in the various regions of the slalom course, or by calculating how early or late the skier is for the individual buoys in the course.
