| Summary: | 碩士 === 國立體育大學 === 運動科學研究所 === 97 === Purpose: The purpose of this study was to compare the differences under different visual condition for dart-throwing. Methods: Twenty-one subjects voluntarily participated this study. In order to obtain throwers’ performance both in segmental motion and dart location, present study used high speed camera (100Hz) to collect data. The study adapted the repeated one-way ANOVA (α＝.05) and qualitative analysis to compare the difference among three different visual condition. Results: The results showed that the dart location of binocular vision were more accuracy and stable than that of advantage vision. The throwing motion of binocular vision and monocular vision weren’t significantly different. The horizontal deviation of dart location of monocular vision was higher than that of binocular vision. The vertical deviation of dart location of monocular vision was also higher than that of binocular vision. Conclusion: The throwing motion of different visual constraint weren’t significantly different, but the information from monocular vision were harmful for judgment including horizontal and vertical direction of judgment. The accuracy and stable of dart location were affected by monocular vision.
