<正>一、组织比赛的出发点要与比赛的目的统一体育课上,教师组织教学比赛的出发点各有不同,其教学比赛所起到的作用、达到的目的和效果也各有不同。教师组织教学比赛的出发点,简单地说就是教师的意图,教师在组织教学比赛时,要针对不同的参赛对象、比赛内容和比赛需要,制定不同的比赛任务和目的,以保证教师的意图与比赛的目的相统一,只有教师的意图和比赛的目的保持一致,教学比赛的价值才能真正显现出来,才能真正体现赛有所用、赛有所值、赛 相似文献

球类比赛数学模拟竞技诊断的理论与实践--以乒乓球比赛分析为例 总被引：5，自引：1，他引：4
介绍了球类比赛数学模拟竞技诊断的理论与方法,并用乒乓球比赛的数学模拟竞技诊断实例进行了说明。数学模拟竞技诊断的基本思想是用一个比赛状态(技术或战术)转移概率矩阵概括地描述一场球类比赛,在此基础上通过马尔可夫链计算比赛获胜概率并进一步确定各种比赛状态(技术或战术)的竞技效率值。与传统的球类比赛分析方法相比较,数学模拟竞技诊断不但能通过各种比赛状态的转移概率对技、战术进行描述性统计分析,而且能确定各种比赛状态(技术或战术)对整场比赛获胜概率的影响。 相似文献

临场组织实施工作是乒乓球比赛的中心环节,能否有条不紊地组织好临场实施工作,对比赛的成败非常重要。通过广东省第二届公安系统乒乓球比赛的裁判工作实践的总结,探讨基层乒乓球比赛组织编排中存在的问题,分析组织实施基层乒乓球比赛的特点和规律。认为与专业大型规模的比赛相比,业余基层乒乓球比赛的组织管理工作有其特殊性,编排灵活机动性较大,为促进基层比赛活动顺利开展提供参考。 相似文献

This study investigated the associations between the characteristics of the nearby physical environment with the total and domain-specific leisure-time sedentary behaviour (SB) in young people. The study included 1578 youth (9–18 years) from the UP&DOWN study. Total leisure-time SB was objectively-assessed by accelerometers. Participants self-reported the time spent during leisure-time in different domains of SB (i.e. screen-based, educational-based, social-based, and other-based SB). Information regarding the basic characteristics of the house, the perceived neighbourhood environment, the amount of physical activity facilities, equipment and materials attainable at home, and the media equipment available at home and in the own bedroom was collected. Linear mixed models were performed, including school and city as random effects. The availability of yard was related to lower total SB and time spent surfing the Internet in boys, but not in girls. More favourable perceived neighbourhood environment was associated with lower total SB and time spent playing video games in girls, but not in boys. The amount of physical activity materials at home was negatively associated with screen-based SB, while the availability of a computer in the own bedroom was positively related to the time spent surfing the Internet in boys and girls. The number of televisions at home and having a computer in the own bedroom was associated with lower time in educational-based SB in boys and girls, respectively. Increasing the number of PA materials at home and decreasing the number of TVs at home and the availability of a computer in the bedroom could improve SB profiles of youth. 相似文献

运用文献资料调研、专家访谈、数理统计、逻辑归纳等研究法,对中外十项全能选手运动成绩表现特征进行剖析.结果显示,中国选手在单项得分对总分贡献率上与世界基本一致,体现了以速度为主的特点,在快速力量、速度耐力等项目上与世界相比存在较大差距.从4大类项对总分贡献率看,中外选手均按跑、跳、投、耐力顺序排列,中国与世界选手的成绩差距不是某单个运动子项的制约,而是体现在跑、跳、投3大项上的全面不足.最后提出了中国十项全能运动发展方向,旨在从中外十项全能选手的成绩特征差异剖析我国运动员成绩提高模式. 相似文献

规律游泳运动促进大鼠操作式条件反射建立的神经机制研究 总被引：3，自引：0，他引：3
采用脑内微透析技术研究活体大鼠海马脑区的相关神经递质在操作式条件反射中的动态变化。结果发现,规律游泳的实验组大鼠操作式条件反射形成更快,其海马脑区谷氨酸和GABA的基础值明显比对照组高,且在大鼠进行条件反射操作的过程中它们的上升幅度也比对照组动物高。结果说明,海马脑区兴奋性谷氨酸能神经元活性增强及抑制性GABA能神经元的调控作用增强使游泳大鼠更快建立条件反射。认为规律的游泳运动可以改善脑内神经元的兴奋性,改变神经元之间突触联系的可塑性,从而促进大鼠的操作式条件反射建立。 相似文献

通过文献资料法、实地调查法、数理统计法、逻辑分析法等研究方法,对甘肃省高校气排球运动的开展情况和气排球引入高校体育公共课程的可行性进行分析,探索地处西北的甘肃省高校中开展气排球公共体育课程面临的问题,积极探寻解决问题的思路并提出相关建议。通过研究显示,在所有甘肃省高校中都没有开设气排球公共体育课程,可以说在甘肃省高校中气排球课程属于空白。制约气排球公共体育课程在甘肃省高校中推广开设的主要因素在于气排球运动普及宣传程度、学校领导支持因素、社会促进因素、教师本领因素、学生爱好因素等。建议加强气排球运动的价值宣传,学校领导和教师积极组织,充分利用学校场地设施等将气排球运动引入到甘肃省高校中来,进而更好地推广开设气排球公共体育课程,丰富高校学生的校园文化生活。 相似文献

Abstract To illustrate changes in elite rugby union match activities, we analysed coded videotape recordings of the first match in each Bledisloe Cup series played between Australia and New Zealand from 1972 to 2004. We also analysed the stature and body mass of players. Effects associated with professionalism, weather conditions, and time (expressed as change per decade) were estimated with a simple generalized linear model and standardized for interpretation of magnitude. The sample size permitted confident conclusions about effects that were of at least moderate magnitude (standardized mean difference >0.6). Increases in passes, tackles, rucks, tries, and ball-in-play time were associated with the advent of professionalism, whereas there were reductions in the numbers of lineouts, mauls, kicks in play, and in mean participation time per player. Noteworthy time trends were an increase in the number of rucks and a decrease in the number of scrums. Good weather conditions were associated with increases in tries and points scored and with reductions in the number of kicks in play and participation time per player. With the advent of professionalism, players have become heavier and backs have become taller. Overall, there have been major changes in international rugby match activities and player size over the past three decades. We believe law changes and developments in match analysis, equipment technology, and player training have contributed to the changes associated with the introduction of professionalism. 相似文献

《Sport Management Review》2020,23(1):1-7
This special issue was designed to advance a research agenda focussed on the management of abuse in sport. Despite progress in the field, greater attention to the structures, policies, processes, practices, and sites in which abuse occurs is required. As such, there is a need for evidence-based solutions to improve the management of abuse and integrity in sport. The authors identified five overarching themes across the 12 papers included within the special issue: the harms and legacies of abuse; abuse in mediated environments; abuse of referees; frameworks that sustain abuse; and safeguarding. The articles included in this issue highlight the complexity of abuse in sporting spaces, the impact it can have on victims and the challenges faced in appropriately managing sporting spaces toward the reduction of harm. This special issue is driven by the authors’ desire to promote integrity and enrich the sporting experience for all, with the hope of driving further research into the management of abuse and integrity in sport. 相似文献

This paper examines the development of association football in the South and West Ulster counties of Fermanagh, Tyrone, Cavan, and Monaghan in the pre-World War One era against the backdrop of the sporting ‘revolution’ and the political and social climate in Ireland at that time. While the Irish Football Association was founded in Belfast in 1880 and the game’s early growth in Ireland was centred in East Ulster, South and West Ulster were areas which were rather dislocated from the hearth of soccer in the province’s largest city, where professional structures were in place by 1894 and where senior and junior association football clubs were strongest. The origins of a number of clubs are examined and it will be shown that despite a lack of major industry and a professional structure, by the early 1900s, the game of soccer had established a strong role within society in many local communities in the area. An examination of the social backgrounds of players and administrators illustrates that leagues and cups were played on a cross-community basis in many areas and that patronage, as well as player participation and administration, came from nationalists as well as unionists. 相似文献
