Abstract

The purposes of this study were to obtain the match activity of high school soccer player, and to examine the measured value between GPS and VTR methods during a match play. The players' match activity ratios of total distance covered were walking 37.8%, jogging 16.6%, running 32.2%, sprinting 6.8%, back-walking 3.9% and back-running 3.1%, respectively. The total distance covered by GPS method was 5140.7 ± 476.6 m, and by VTR method was 5105.6 ± 459.8 m. As for the total distance covered, no significant difference was found between GPS and VTR methods. These finding,s gave suggestion that the distance covered by soccer player could be used with mobile GPS receiver. In the near future, more new accurate data will be got with GPS technique of new receiver in high quality.
