动作发展视域下幼儿足球促进粗大动作发展水平研究     

孙启成  刘金富  朱小烽 《浙江体育科学》2020,(3):57-63

探讨幼儿足球对幼儿粗大动作发展水平的影响,为干预幼儿粗大动作发展提供依据。选取嘉兴市108名5~6岁幼儿为受试对象,以班级为单位随机分为干预组与对照组。干预组进行12周幼儿足球游戏活动教学,2次*40min/周;对照组幼儿为静态性的课堂班级活动。干预前后采用PGMQS测量幼儿位移能力、操控能力及平衡能力。采用独立样本t检验、配对样本t检验及协方差分析两组幼儿前后测结果的差异性。结果显示:①干预前,两组幼儿粗大动作发展水平无显著性差异(P>0.05);干预后,两组幼儿粗大动作发展水平存在显著性差异(P<0.05),干预组高于对照组。②干预组和对照组幼儿后测结果与前测结果间均存在显著性差异(P<0.05),后测结果高于前测。研究结果表明幼儿粗大动作发展存在延长效应,但结构化幼儿足球游戏活动明显提高了幼儿粗大动作发展水平。因此建议抓牢幼儿早期动作发展的敏感期,以动作发展为主线科学设计幼儿足球游戏活动并保证活动的顺利开展,为幼儿健康、全面发展奠定良好的基础。  相似文献   

The determinants of stadium attendance in elite women’s football: Evidence from the UEFA Women's Champions League     

《Sport Management Review》2020,23(3):509-520

Women’s football struggles to build a solid platform in terms of fan interest. However, while an increase in gate receipts can help assist its long-term sustainability, there is limited evidence in the academic literature on the factors influencing spectator demand in women’s football. The authors investigate determinants of stadium attendance for UEFA Women's Champions League (UWCL) matches. Using regression models deployed on 554 UWCL games played between 2009/10 and 2017/18, the authors examine contextual and sport-related variables as the main predictors of stadium attendance. Findings show that there is no continuous growth of attendance over the period examined, and highlight that spectators’ interest is positively associated with five factors: stage of the competition, uncertainty of match outcome, competitive intensity, away club’s reputation and weather conditions. Football governing bodies should put in place initiatives to ensure match outcome uncertainty is maintained as this represents a key determinant to maximise stadium attendance. Based on the specific context of European women’s football, recommendations to foster its development are discussed. These include incentivising investment into the elite women’s game and designing sport policies to encourage participation at grassroots levels.  相似文献   

校园足球改革背景下高校足球文化的内涵与构建     

陈鹏 《当代体育科技》2020,(11):123-124

在我国校园足球改革背景下,高校对足球教学的重视程度越来越高。但是值得注意的是,现阶段我国部分高校对足球文化的内涵的了解仍旧停留在较为肤浅的层面,并没有充分认识到足球文化构建的重要作用,足球文化构建过程中还存在着较多的不足,足球文化构建效果并不理想,不利于高校足球教学工作的开展。本文从校园足球文化的概述入手,对校园足球改革背景下高校足球文化的内涵进行了深入的分析,并提出了几点校园足球改革背景下高校足球文化构建策略,以期能够为高校提供些许参考。  相似文献   

我国新校园足球竞赛体系的运行现状考察与治理路径研究     

郝文鑫  方千华  蔡向阳  李守江 《武汉体育学院学报》2020,54(7):87-93

新校园足球竞赛体系已初具雏形，建成特点鲜明的校内外四级联赛体系。竞赛组织处于体育、教育部门"双轨制"主导局面。竞赛目标从"足球后备人才培养"演化为"夯实中国足球持续健康发展的人才基础"。赛事系统呈现出明显的学段差异。赛事相关的资源配置亟待提升。当前我国校园足球竞赛体系面临政策发展不统筹、人才供应链不配套、校园与职业赛事阻塞、竞赛保障资源配置不足、赛事监督评价落后的困局，竞赛体系整体正处在由"做大"到"做强"的十字路口。在由"基础建设"到"内涵发展"理念指导下，提出具体治理路径。政策治理层面：统筹竞技普及，发挥政府引导整合作用；人才流通层面：构建选拔机制，畅通各学段人才供应链；跨域融合层面：突破体制屏障，衔接职业足球竞赛体系；资源保障层面：调动多元参与，加强竞赛保障体系建设；监督治理层面：运用智慧监管，推进监督评价的科学化。  相似文献

Mixed control of uncertain jumping time-delay systems     

Magdi S. Mahmoud  Fouad M. AL-Sunni  Yan Shi   《Journal of The Franklin Institute》2008,345(5):536-552

In this paper, we investigate a class of linear continuous-time systems with Markovian jump parameters. An integral part of the system dynamics is a delayed state with time-varying and bounded delays. The jumping parameters are modeled as a continuous-time, discrete-state Markov process. Employing norm-bounded parametric uncertainties and utilizing the second-method of Lyapunov, we examine the problem of designing a mixed controller which minimizes a quadratic performance measure while satisfying a prescribed -norm bound on the closed-loop system. It is established that sufficient conditions for the existence of the mixed controller and the associated performance upper bound could be cast in the form of linear matrix inequalities.  相似文献   

The multi-paradigmatic character of contemporary educational action research: a promising perspective or an underlying threat?     

Eleni Katsarou 《Educational Action Research》2017,25(5):673-686

From the very first moment action research started to be used in the social research field until now, it has presented significant variations. Action research looks like a mosaic of theoretical and methodological approaches, named differently from time to time and/or from place to place: for example, practitioner inquiry, practitioner research, teacher research, participatory action research, and so forth. The basic aims of this article are to find the reasons for this and to discuss the implications of the phenomenon. Starting with the first issue, we could ask ourselves: why do we today find so many and considerable variations in action research approaches in the literature? The evident reason is because action research draws upon many theoretical paradigms that – in some circumstances – are not only different, but also contradict each other. Hammersley states characteristically that action research draws upon positivism, pragmatism, hermeneutics, critical theory and postmodernism! After such claims, we can easily wonder: how can such a multi-paradigmatic approach compose cohesive methodological proposals? We can also pose another crucial question: although we can easily understand that this multi-paradigmatic nature is a real advantage which gives action research a pluralistic essence, is it really ‘a strong indicator of the power of action research to reinvent itself according to local needs’ as Somekh stated, or might it at the same time conceal serious risks?  相似文献
