目的:分析射箭選手在反曲弓競賽項目中的技術表現。對象:我國2006年亞運反曲弓射箭決選的男子、女子各八位選手,分析資料包括資格賽和對抗賽的全部過程。方法:應用Facets測驗軟體分析競賽資料,根據射箭競賽的特性,將技術分成四個重點(層面):選手、距離、回合和放箭順序等分析。利用適合度考驗、難度、估計誤差和非期望反應建立各層面技術的量尺,然後根據非期望反應和標準殘差,再探討選手個人的技術表現。結果:提供教練訓練和比賽客觀的數據,排除主觀判斷的缺點且提升選手的成績表現。結論:是利用客觀測量的非期望反應,可以探查反曲弓射箭競賽的選手技術。
Purpose: the study was to analyze the shooting skills of archers in Recurve. Subjects: sixteen archers who were in the selection of national team for Asian Games in 2006. The data of performance included the qualification and elimination rounds in Recurve. Method: the data were analyzed by Facets Rasch software. According to characters of archery, the shooting skill of Recurve included four key elements (facets): Archer, Distance, End and Order. The scale of skill was created, using Infit (the information-weighted mean-square fit statistic), Outfit (the outlier sensitive, mean-square fit statistics), Measure (logit estimate of the calibration/measure in log odds units), Model S.E. (standard error), and unexpected responses in all facets. An individual skill type and character were based on unexpected responses and standardized residual to analyze further. Results: providing objectively information that coaches might use in drill and games. It eliminated the subjectivity and promoted athletes' performance. Conclusion: using the unexpected responses of Rasch measurement might detect the skill outcomes of archers in the Recurve.
