集训的日子是无声无息的,也是有条不紊的.除了教练的指导外,剩下的主要靠自己实战、解拆、看名家讲座,有时为了一个变例分支,我们两个人竟真刀真枪地大动干戈,一天的时间好像一眨眼.我每天都记日记、写心得体会,这是我的秘密武器,也是多年来养成的好习惯,实践证明,这种方式是卓有成效的.在我的感染下,我的搭档老杨也动起了笔,把一些重要棋局、典型待审盘面专门在笔记本上记下. 相似文献

中、日、韩三国青少年足球培养体系比较研究 总被引：7，自引：0，他引：7
通过查阅文献资料和专家访谈等方法,对中、日、韩三国青少年足球培养体系进行比较后发现:日本较中、韩两国的发展目标长远;日、韩非常重视学校足球的开展,中国则过多依赖俱乐部后备梯队和足球学校;中国青少年足球人才培养成本远远高于日、韩两国;中国高水平的青少年足球教练员较少,围绕青少年足球运动员培养的理论研究还不够深入,缺乏先进的、科学的训练理念和方法手段;日、韩高度重视青少年足球人才文化教育,中国却将足球训练与文化学习对立起来.根据国情,借鉴日、韩成功经验,提出改变中国青少年足球培养工作落后面貌的对策:足球管理部门、教育部门、社会企业以及家庭要多方共同携手;要高度重视青少年足球人才的文化教育,树立"以足球培育完人"的培养思想;加强青少年足球教练员队伍建设,做到科学化指导与训练;要充分利用中国的人口优势,只有在全国范围内掀起青少年足球热潮,中国足球才能真正做到可持续发展. 相似文献

以SD大鼠为研究对象,并将其随机分成一次性运动组、耐力运动组和间歇运动组,其中每组再分成服用抗氧化剂和不服用抗氧化剂两组共6组,所用大鼠在完成最后一次运动后,分别于运动后即刻、运动后24h和运动后48h处死取样,并对心肌线粒体cAMP、cGMP进行测定,以研究不同运动方式和抗氧化剂对大鼠心肌代谢的影响,为运动训练提供参考.实验结果表明:服用抗氧化剂对耐力运动组和间歇运动组恢复期的心肌cAMP浓度具有一定的影响,而对这两组恢复期的心肌cGMP浓度则并无显著性作用;运动方式和抗氧化剂是影响心肌cAMP、cGMP浓度变化的主要因素. 相似文献

我患慢性鼻炎多年,一遇到感冒就如火上加油,鼻塞更严重了.此时,我才意识到感冒不除鼻炎好不了.于是,我决心治感冒.不久,我的眼睛傍晚开始疼痛,到眼科看了几次,有的医生疑为青光眼,但多次测眼压都正常;还有的医生疑为神经性眼痛.在我束手无策之际,我在有关报刊上看到了《冷水洗脸温水牙热水脚》、《摩鼻洗脸预防感冒》等文章,读后,我觉得文中推荐的非药疗法既适合治疗我所患的病又简单易行.于是我决定试用,自己设计了一种"三浴"法. 相似文献

中国居民参加体育锻炼的区域差异比较 总被引：6，自引：1，他引：5
我国自1997年来先后3次对群众体育现状进行了调查,2007年第3次群众体育现状调查覆盖了全国31个省(自治区、直辖市),有效样本88 625人.调查内容涉及参加体育锻炼的质量、方式、消费、目的和需求等.研究表明,我国居民体育锻炼参与情况和我国社会经济水平的区域趋势相似,具有明显的东、中、西部区域差异,东部地区居民体育锻炼的总体情况好于中、西部地区,沿海区域高于内陆区域.居民参加体育锻炼具有的东、中、西部区域差异主要体现在体育锻炼的质量、消费水平、锻炼中断等方面.北方居民参加体育锻炼的人数比例和经常锻炼的人数比例均略高于南方,同时表现出参与频度较高、持续时间较短、锻炼强度较低等特点.积极参加体育锻炼这一类人群的比例在全国各区域的分布均衡,差异较小,约占总人数的0.6%. 相似文献

This paper considers girls' participation in running and other outdoor physical activities in their local areas in London, UK. The paper is concerned with the operation of risk discourses in and around this participation and looks at the way that such discourses impacted on girls' opportunities to take part in physical activities that required outdoor space. Drawing on data from longitudinal research into girls' participation in sport and physical activity, the findings suggested that girls, in particular, were subject to risk discourses around their participation in physical activities which constructed the girls as ‘weak’, and ‘vulnerable’. I look at the ways in which girls understood these messages and how they came to define certain spaces and activities as either ‘safe’ or ‘unsafe’. I look in particular at how girls were able to resist certain constructions of their embodied physical capacities and also at the ways in which this was constrained by specific incidences of sexual harassment. 相似文献

This paper identifies ‘quality’ as an internationally relevant concept to be problematised in contemporary debates about physical education (PE). Drawing on the conceptualisation of curriculum by B. Bernstein in 1977, pedagogy and assessment as three inter-related message systems of schooling, the paper presents and explores curriculum, pedagogy and assessment as three fundamental dimensions of ‘quality PE’. Discussion addresses what quality in each dimension may mean in PE, and demand in practice. Contemporary initiatives in Australia and New Zealand provide a reference point for exploring the prospective application of quality conceptualised in terms of the three inter-related dimensions. Attention is drawn to frameworks in mainstream education that may be utilised in endeavours to critically review current practices, and inform developments directed towards achieving quality in PE. It is argued that achieving quality in PE requires that quality is pursued and demonstrated within and across curriculum, pedagogy and assessment, and that meanings of quality always need to be contextualised in cultural, social and institutional terms. 相似文献

Disinfection by-products (DBPs) are generated through the reaction of chlorine with organic and inorganic matter in indoor swimming pools. Different DBPs are present in indoor swimming pools. This study evaluated the effects of different chlorinated formations in oxidative stress and lung damage in 20 swimmers after 40?min of aerobic swimming in 3 indoor pools with different characteristics. Biological samples were collected to measure lung damage (serum-surfactant-associated proteins A and B), oxidative stress parameters (plasma protein carbonylation and malondialdehyde, and whole-blood glutathione oxidation), and swimming exertion values (blood lactate) before and after exercise. Free chlorine and combined chlorine in water, and chlorine in air samples were determined in all the swimming pools. Chlorination as disinfection treatment led to the formation of chloramines in water samples, mainly mono- and dichloramine. However, free chlorine was the predominate species in ultraviolet-treated swimming pool. Levels of total chlorine increased as a function of the swimming activity in chlorinated swimming pools. The lower quality of the installation resulted in a higher content of total chlorine, especially in air samples, and therefore a higher exposure of the swimmer to DBPs. However, the concentration level of chlorinated DBPs did not result in significant variation in serum-surfactant-associated proteins A and oxidative stress parameters in swimmers. In conclusion, the quality of the installation affected the DBPs concentration; however, it did not lead to lung epithelial damage and oxidative stress parameters in swimmers. 相似文献

We propose a Theory of Challenge and Threat States in Athletes (TCTSA) which is an amalgamation and extension of the biopsychosocial model of challenge and threat, the model of adaptive approaches to competition and the debilitative and facilitative competitive state anxiety model. In the TCTSA we posit that self-efficacy, perceptions of control, and achievement goals determine challenge or threat states in response to competition. Distinct patterns of neuroendocrine and cardiovascular responses are indicative of a challenge or threat state. Increases in epinephrine and cardiac activity, and a decrease in total peripheral vascular resistance (TPR) characterise a challenge state and increases in cortisol, smaller increases in cardiac activity and either no change or an increase in TPR characterise a threat state. Positive and negative emotions can occur in a challenge state while a threat state is associated with negative emotions only. Emotions are perceived as helpful to performance in a challenge state but not in a threat state. Challenge and threat states influence effort, attention, decision–making and physical functioning and accordingly sport performance. The TCTSA provides a framework for practitioners to enhance performance, through developing a challenge state, and encourages researchers to explore the mechanisms underlying performance in competition. 相似文献
