碩士 === 國立臺灣師範大學 === 運動競技學系 === 103 === The purpose of this study is to analyze the performance of 60-meter sprinting on the curve by using the high-speed camera as part of measurement tools. The study will provide resources for assisting teachers and coaches in their teaching and training. Ten students participated in the research study: five seventh graders and five eighth graders (average age is 11.26). The research has two aims: to understand students’ cumulative time, number of steps, stride rate, stride length and the variation of running speed, and also to analyze the impact of each condition and to discuss the methods for improving running techniques. The results of the study are: 1. During the 60-meter run, the average of cumulative time was 10.51 seconds and the average steps were 38.5 steps. 2. According to step frequency, the fastest stride rate was 3.74 seconds during the segment of 20-30m for eighth grade students; as for seventh grade students, the fastest stride rate was 3.75seconds during the segment of 20-30 meters and 30-40meters. 3. During 30-40 meters and 50-60 meters, the longest stride length of seventh grade students was about 1.62 meters and 1.71 meters for eighth grade students.
