近年来校园足球得到高度重视,但是各个地方的中小学足球训练方法还是比较陈旧,教师没有开放自己的思想,导致实施的结果与成绩不理想,因此本文尝试将耗散结构理论与混沌融入校园足球训练中,尝试探讨耗散结构理论在校园足球训练中的应用。使我国足球训练达到一定的水平及高度,首先要做的是学校体育管理者、足球教练、学生以及学生家长们在足球训练发展的各方面保持思想的开放性、远离平衡态,从而推动我国校园足球训练的健康全面发展,形成一套训练方法理念以及训练体系。  相似文献

ABSTRACT

This study aimed to examine the effects of two jump squat (JS) training programs involving different loading ranges in under-20 soccer players during a preseason period. Twenty-three elite young soccer players performed sprint speed (at 5-, 10-, and 20-m), change-of-direction (COD) speed, JS peak-power (PP), and countermovement jump (CMJ) tests pre and post four weeks of training. Athletes were pair-matched in two groups according to their optimum power loads (OPL) as follows: lower than OPL (LOPL; athletes who trained at a load 20% lower than the OPL) and higher than OPL (HOPL; athletes who trained at a load 20% higher than the OPL). Magnitude-based inferences were used to compare pre- and post-training measures. Meaningful increases in the PP JS were observed for both groups. Likely and possible improvements were observed in the 5- and 10-m sprint velocity in the LOPL group. Meanwhile, possible and likely improvements were observed in the CMJ, 5- and 10-m sprint velocity, and COD speed in the HOPL group. Overall, both training schemes induced positive changes in athletic performance. Soccer coaches and sport scientists can implement the JS OPL-based training schemes presented here, either separately or combined, to improve the physical performance of youth soccer players.  相似文献

足球运动在世界范围内的普及化与社会化程度日益增强,各国(地区)若要获得全球化竞争中的优势,应注重探讨社会与足球运动发展的关系。通过对1993-2017年131个国家(地区)的人类发展指数与足球排名积分的面板数据建模,以揭示两者之间的关系。研究结果表明,不同国家(地区)的人类发展指数对足球运动发展的影响应建立个体和时点双固定效应模型,模型最高的R2为0.871 32,F检验值为71.014 65,P<0.001,该模型具备较高的解释能力。结论:固定效应模型在考虑历时性因素与不宜观测因素后,在1993-2017年阶段,人类发展指数对于足球运动的发展作用存在分化现象,尤其对亚洲与人口大国的足球运动发展存在制约作用,对南美洲与中等人口国家存在促进作用,人类发展指数与足球运动发展存在一定的或然关系。人类发展指数反映了社会发展的综合水平,对于存在制约效应的国家而言,应当着重考虑社会其它领域(经济、教育、医疗卫生等)与足球运动的互动、协同与融合发展。  相似文献

对我国校园足球文化建设中若干问题进行深入分析和探讨,揭示我国校园足球文化建设的内在逻辑关系,研究发现:1)我国校园足球文化建设与其所具有的游戏本质、教育属性和社会属性密不可分。2)育人目标窄化、育人主体导向偏失、人文精神缺乏导致了校园足球实施中教育本原的漠视;足球生存场域发生变化、工具化足球的演进、足球发展理念不定导致了校园畸形足球形态的盛行。研究认为我国校园足球发展应把握与社会发展协调一致原则,强调顶层设计与实际需求相互适应的指导思想,以及打造生活化的校园足球实践活动行动方案。  相似文献

The identification and development of players in English professional football has become an increasingly significant topic of debate given the historical perceived underperformance of the English national team at international tournaments. To enhance understanding of the challenges and barriers experienced by English youth footballers, the authors explore the developmental experiences of English professional football players from different levels of the English football pyramid. Professional players (N = 11) from football clubs in the top four professional divisions in England took part in individual semi-structured interviews, which were analysed inductively using thematic analysis. The data revealed three interrelated themes that were perceived to mediate player identification and development pathways at professional clubs. Pathways for young players to progress and experience first-team competitive football differed when the level of the league that the players operated within was considered, with significant issues also raised relating to the suitability of the under 21 league structure, the importance attached to the educational welfare of young players, and variations in the identification of player attributes. This study sheds new light on the priorities and processes of talent development and education provision in English football.  相似文献

运用文献研究法、饱和经验法、典型案例分析法对苏、浙、沪三省市地方足球协会进行实证研究,依据软法制定主体和实施主体的不同,提炼概括了当前地方足球协会的两种软法治理模式,即省级层面地方足球协会"政府主导型"软法治理模式和市级层面地方足球协会"多维互动型"软法治理模式,并对这两种模式的特征进行比较分析。继而归纳了当前地方足球协会软法治理"程序缺失、责任制度不规范、承诺滞后和权利救济缺失"的四个困境,从"内部法人治理结构、相关主体法治观念、软法的程序、监督问责机制"四个方面阐释了产生软法治理困境的原因,最后提出四项地方足协软法治理的对策建议。  相似文献

ABSTRACT

The aim of this study was to compare the effects of 20 min neuromuscular training with a programme of 10 min in youth football players. 342 (15.4 ± 1.7 years) male football players from 18 teams were included, and cluster-randomized by team into two intervention groups. Both groups performed an injury prevention programme twice a week over five months using the same exercises but a different duration. The first intervention group (INT10, n = 175) performed the programme for 10 min, the second intervention group (INT20, n = 167) for 20 min. Primary outcomes were lower extremity (LE) injuries. Secondary outcomes were injury type, severity, mechanism and compliance to the intervention. 13 teams with 185 players were included for final analysis. No significant group difference was found between INT10 (6.37 per 1000 h) and INT20 (7.20 per 1000 h) for the incidence rate ratio of the lower extremities (IRR = 1.03, 95% confidence interval 0.59, 1.79), nor for the distribution of injury location, type, severity or mechanism. The results show that performing preventive exercises for 10 min is no less effective than 20 min in youth football players. Shorter training sessions can, therefore, be effectively used for injury prevention.  相似文献

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

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
