| Summary: | 碩士 === 國立花蓮教育大學 === 體育教學碩士學位班 === 95 === This research aims to investigate the relationship of swimming speed, stroke rate, and stroke length in swimming contest. Participants are 13~14 and 15~17 years old boys and girls in 100m freestyle final of 2006 National Winter Swimming Championship 25m. Video cameras were used to record the race and were used to take the stroke data. The stroke data of each group was analyzed by SPSS for windows 10.0 software to investigate the variations of stroke data in 100m freestyle race. The findings of this research show:
1. Group 15 to 17-year-old boys (G15-17Bs) are significantly faster than group 13 to 14-year-old boys (G13-14Bs). G13-14Bs have longer stroke length and slower stroke rate than G15-17Bs in first 25m but G13-14Bs are shorter and slower than group G15-17Bs in second 25m.
2. These four groups change in the four sections within 100m in terms of stroke rate, stroke length and velocity.
3. The stroke rate and stroke length of group 13-14 girls and group 15-17 girls are not significant difference.
4. There are no significant difference between G13-14Gs and G15-17Gs in terms of stroke rate, stroke length and velocity.
5. The difference of inter-group swimming speed results from stroke rate； the difference of inter-group swimming speed results from stroke length.
