The purpose of this study was to analyse the effect of bike type – the 26-inch-wheel bike (26“ bike) and the 29-inch-wheel bike (29“ bike) – on performance in elite mountain bikers. Ten Swiss National Team athletes (seven males, three females) completed six trials with individual start on a simulated cross-country course with 35 min of active recovery between trials (three trials on a 26“ bike and three trials on a 29“ bike, alternate order, randomised start-bike). The course consisted of two separate sections expected to favour either the 29“ bike (section A) or the 26“ bike (section B). For each trial performance, power output, cadence and heart rate were recorded and athletes’ experiences were documented. Mean overall performance (time: 304 ± 27 s vs. 311 ± 29 s; P < 0.01) and performance in sections A (P < 0.001) and B (P < 0.05) were better when using the 29“ bike. No significant differences were observed for power output, cadence or heart rate. Athletes rated the 29“ bike as better for performance in general, passing obstacles and traction. The 29“ bike supports superior performance for elite mountain bikers, even on sections supposed to favour the 26“ bike. 相似文献

AbstractStudies on the development of Olympic Solidarity as a tool of the International Olympic Committee (IOC) to enable National Olympic Committees of developing countries access to resources and influence in the Olympic Movement exist. However, historical scholarship has relatively neglected the development of aid programs by International Federations to explain how they made use of resources to gain influence in international sport politics. Based on extensive multi-national and multi-lingual archival research in the archives of the International Association of Athletics Federation (IAAF) and the German Sport University Cologne, this article explores the establishment and development of the IAAF‘s Technical Aid Program, which had been installed in 1974. Referencing a large amount of previously unknown protocols and written correspondence, the paper critically discusses the IAAF‘s development activities in light of two parallel occurring processes that shaped the federation’s character in the 1970s and 1980s decisively: its increasing commercialization and its path towards democratization in its voting system. It is argued that the IAAF development programs served as a tool to enforce commercial and sport political interests whilst the nature of support remained without clear guidance until the mid-1980s. 相似文献

AbstractThis paper examines the confluence of global, regional, and national politics in the lead up to the 1991 Pan-American Games hosted by Cuba. Cuba’s contentious selection as host was wholly underpinned by the international politics of the time. Once selected, the preparations for the Games in Havana were surrounded by an unprecedented domestic economic crisis fueled by shifts in global politics. This paper analyzes how international politics informed the hosting of the 1991 Pan-American Games, and shaped the political challenge the Cuban government faced in hosting such an event. The Revolution’s use of sport domestically and internationally came to the forefront in its efforts as host and the results of those efforts proved to be providential given the emerging political economic contexts during and in the ensuing years after the Games. 相似文献

AbstractPhysical exercise, beyond the mere physical aspect, is very much a social construct. But it is as well a means of constructing the social and as such it can be used in different ways. The contribution, taking a broad comparative perspective, will reflect on two major possibilities: the one may be called social inclusion as subordination and the other can be looked at as a matter of social inclusion by strengthening individuals. This also allows an understanding of new dangers of exclusion in the era of liquid modernity. 相似文献

中国传统的文化背景始终存在大传统与小传统的对立与交融。其中大传统始终是历史的主流 ,是历史学家的关注所在。而小传统则相对处在话语弱势与忽略之中。然而小传统下的世俗社会的发展始终延续着 ,是没有被历史记录的另一条历史线索。将小传统纳入历史话语权力中 ,从而呈现历史与社会的全貌 ,是史学发展的新方向 ,也是现代历史学家面临的课题与挑战 相似文献

哲学社会科学成果与自然科学成果同样重要,哲学社会科学成果也是综合国力的体现,这是由哲学社会科学的地位所决定的,是由改革开放20多年坚持理论创新取得巨大成就的事实和中国历史史实所证明了的。而以美国为首的西方敌对势力推行的思想化渗透政策的巨大危害,又从反面证明了哲学社会科学成果对综合国力的影响。 相似文献

汉语"道歉"话语模式 总被引:2,自引:1,他引:2
罗朝晖 《暨南大学华文学院学报》2004,(1):52-58
道歉是交际中的一种补救性施事言语行为,也是一种礼貌的社会行为。其基本功能是为一项冒犯行为提供补救办法,恢复社会平衡与和谐。从语言形式来看,道歉具有语义句法程式化和规约化的普遍特征。本用语篇补全测试的问卷形式通过对汉语中道歉行为实施的调查、对所选策略进行了分类统计,结果表明道歉的话语模式包括多种策略和手段的组合,但策略的选用在很大程度上受到如权势、距离等因素的制约,说明道歉行为对化等因素的依赖。 相似文献

The cadence that maximises power output developed at the crank by an individual cyclist is conventionally determined using a laboratory test. The purpose of this study was two-fold: (i) to show that such a cadence, which we call the optimal cadence, can be determined using power output, heart-rate, and cadence measured in the field and (ii) to describe methodology to do so. For an individual cyclist's sessions, power output is related to cadence and the elicited heart-rate using a non-linear regression model. Optimal cadences are found for two riders (83 and 70 revolutions per minute, respectively); these cadences are similar to the riders’ preferred cadences (82–92?rpm and 65–75?rpm). Power output reduces by approximately 6% for cadences 20?rpm above or below optimum. Our methodology can be used by a rider to determine an optimal cadence without laboratory testing intervention: the rider will need to collect power output, heart-rate, and cadence measurements from training and racing sessions over an extended period (>6 months); ride at a range of cadences within those sessions; and calculate his/her optimal cadence using the methodology described or a software tool that implements it. 相似文献

教育作为人类文化传播的载体,是通过学校这个阵地来实现其功能的。学校图书馆是学校文化管理的基地。学校图书馆的馆藏应“虚”“实”结合,“藏”一切信息载体,应发挥它的新的服务功能,使图书馆的文化育人职能得以充分地展现。要采取有效措施,满足文化育人的要求,用文化因素塑造学校精神。 相似文献

冷冻站设备中制冷机组的电耗是影响制冷效率高低的重要因素,提高制冷机组的制冷效率是节能的关键环节。根据制冷机组的运行特性,可以通过制冷机组的台数控制达到节能的目的。而提高温度传感器和流量传感器的测量精度,对冷冻水温进行再设控制是群控的两种重要策略。 相似文献
