青年男子足球守门员技术水平评价方法的研究

Research on Evaluation Method of Young Male Football Goalkeepers' Techniques

运用文献资料法、专家调查法和数理统计法,对青年男子足球守门员技术水平的评价指标体系和评价方程进行构建。根据专家对各指标认识的一致性和专家建议,以及指标的得分、变异系数等,对25个二级指标进行筛选,并对指标的信度和效度进行了检验。得出结论:建立的青年男子足球守门员技术水平评价指标体系具有良好的信度和效度,包括"接球""托球""拳击球""发球"4个一级指标和16个二级指标。归一化处理后4个一级指标的权向量为0.366 7,0.090 6,0.049 2,0.493 5;本研究建立的评价指标体系和评价方程可直接用于青年男子足球守门员训练和考核状况评价。

By literature review, expert interview and mathematical statistics, this paper tries to construct the evaluation index system and evaluation equations of young male football goalkeepers＇ technical levels. According to index score, coefficient of variation, consistency of the indicators＇ recognition from experts, and the suggestions recommended by the experts, 25 secondary indicators were screened, and the reliability and validity of the indicators have been tested. This paper concludes that the constructed evaluation index system of young male football goalkeepers＇ technical levels have acceptable validity and reliability, including four first-level evaluation indexes, that is ＂clean catching＂, ＂finger-tip save＂, ＂listing ball＂ and ＂goalkeeper＇ s serve＂ respectively, and 16 second-level evaluation indexes. After normalizing the four first-level evaluation indexes, the weight vectors are as follows： 0. 366 7, 0. 090 6, 0. 049 2, 0. 493 5. The evaluation index system and evaluation equations established by the research can be directly used for training and evaluation of young male football goalkeepers＇ technical levels.
