This article compares East Germany's Cold War-era approach to doping to that of the USA's in terms of their respective impacts on medical risk. Although deserving of criticism on many levels, the GDR doping programme featured a number of safeguards designed to minimise medical dangers. Unlike their East German counterparts, American governmental units were not directly involved in the administration of performance-enhancing substances. The US approach to doping was not ideal in terms of medical risk, however. As a result of the country's regulatory approach to doping, the country's athletes frequently turned to black market sources for doping agents. It was also relatively common for American athletes to use performance-enhancing drugs without the benefit of medical supervision. The US approach to doping was in these ways inferior to that of East Germany's on the subject of medical risk.  相似文献

在对第2届环青海湖国际公路自行车赛全体中、外参赛运动员比赛成绩进行统计处理和全面分析基础上,着重对成绩较好的中、外运动员进行相对成绩、平均排名、速度方差和相对速度方差各项指标的对比分析。结果显示:我国优秀运动员有与国外优秀运动员抗争的实力,而团队整体实力与国外强队仍有一定差距,处于中等水平;在全程速度分配上较为合理,但相对速度能力较差,关键性赛段波动较大,参与激烈竞争的能力远不如国外优秀运动员。  相似文献

St Louis staged the third modern Olympics in 1904, an event most historians have labelled as a less than memorable occasion and some have contended nearly derailed the nascent Olympic movement. Consigned to a regional hamlet rather than a global city, the 1904 St Louis games were supposedly a model of how not to conduct an Olympian spectacle. Taking a different perspective, however, the St Louis games had a profound influence on how the United States has staged Olympics. The Olympics have not been held in established or well-known American metropolises but have consistently gone to up-and-coming cities in border regions eager to make national and global reputations. In addition, the 1904 St Louis games were held in a legally segregated city but permitted the inclusion for the first time of African-American athletes in Olympic competition. Race and region provided foundations for American interpretations of the 1904 Olympics and have remained paramount in national memories of Olympian events ever since. From St Louis in 1904 through Atlanta in 1996 race and region have been central themes in American Olympic experiences.  相似文献

Skiing underwent substantial changes during the post-war years when the sport turned into a multi-billion dollar industry and a leisure activity for the masses. Despite its global nature and popularity, skiing in academic writing has not gained much recognition. This paper explores the role of knowledge transfer during the pioneering phase of post-war skiing in Australia. It describes the life of Charles William Anton, an Austrian refugee from the Anschluss who migrated to Sydney and subsequently became one of the founding fathers of Australian post-war skiing. The following pages show the multi-layered nature of skiing as a global sport by exemplifying how ideas spread from pre-war Europe to post-war Australia. The paper will also provide a case study about refugee knowledge transfer and the ‘productive process of absorption, adoption or rejection of knowledge’ that takes place once an idea has been introduced into a new environment.  相似文献

鼎最早是中国古代烹饪食物的器皿,有金属、陶瓷等材质之分。由于还要用它盛满食物摆列在宗祠内,被赋予了祭祀天地、神灵、祖先等重要功能,所以坚固、美观的铜鼎成为中国古代的重要礼器。古代的王公贵族在自己的宗庙中一定要摆放象征权势和地位的不同数量的列鼎,遂有古人的"问鼎"之典;死后往往要放入一、三、五、七等不同数量的铜鼎陪葬,以  相似文献

Despite the apparent benefits of Title IX, the implementation of the law remains controversial, and there are divergent beliefs regarding its impact on collegiate sport. The purpose of this study was to examine how members of a university community, whose intercollegiate sport programs have changed, perceive and make sense of Title IX and the changes it incurred. Using a gendered lens (Birrell, 2000) and qualitative interviews with 13 individuals connected to the university community, insight was gained into their perceptions of Title IX and women's and men's athletic opportunities. The theme of opportunity gained and lost was central to how these individuals perceive Title IX and resonates with the liberal (feminist) concerns out of which Title IX was born.  相似文献

This article invites historians to reconsider the nature of sport, which is here defined as essentially aesthetic. The sporting aesthetic, however, is a by-product of competition as athletes struggle to outperform their rivals and to overcome their own limitations. It is argued here that these aesthetic qualities have been captured in two documentaries by the Danish film-maker J?rgen Leth – Stars and Water Carriers (1974) and A Sunday in Hell (1976) covering the 1973 Giro d'Italia and the 1976 Paris-Roubaix cycle races respectively. Leth's films effectively challenged contemporary Marxist views that sport was simply a banal distraction or a means of legitimizing the capitalist system. Their power, it is suggested, lies in their depiction of grand, heroic themes that echo classical myth and legend. Indeed, sport's enduring popularity may reside in its capacity to offer a glimpse of an mythological universe that has been marginalized by modernity.  相似文献

The resistance against a cyclist while riding on rollers is due mainly to rolling resistance produced by the deformation of the tyre as it rolls against small diameter drums. Resistance is then combined with wheel speed to set power output. The effect of tyre pressure and cross-section on power was investigated by systematically altering the pressure (552 kPa, 690 kPa, and 827 KPa) in a 20c, 23c, 25c, and 28c tyre of the same design while riding at a wheel speed of 45 kph. Average power over 1 minute was measured with a Power Tap Hub (Tune Corporation, Cambridge, Massachusetts, USA) on five occasions. Statistical significance was evaluated at p < 0.05. Power requirements increased significantly with each reduction in tyre pressure for all tyres and pressures except the 25c between 690 and 827 kPa. The 20c tyre required significantly more power from the cyclist at each tested tyre pressure when compared to the other tyres (which were not different from each other). The differences in resistance from tyre size were not observed when ridden on the road. Additionally, a slightly different tyre design from the same manufacturer responded similarly in the 20c, but was significantly different in the 23c size. It was also observed that power requirements increased significantly when both the wheels were ridden on the rollers as compared to just the rear wheel. These results indicate that the power requirements may be significantly altered by the cyclist by adjusting tyre pressure, tyre cross-section size, tyre type, and with the number of wheels contacting the rollers. However, the magnitude of these power requirements may not be suitable for intense workouts of trained cyclists.  相似文献

自行车骑行是一项有利于健康的运动项目,在日常生活中鼓励人们更多地采用自行车代步出行和骑车锻炼对于促进公共健康、降低慢性疾病发病率具有重要意义。近年来许多国家和地区在大力推行自行车骑行和自行车复兴的政策、项目和规划。但自行车骑行同时也存在一些不利于健康的负面因素,通过在道路骑行中采取一些保护措施可以在一定程度上抵消道路骑行对健康的负面影响,达到骑行健身的效果。综述了近年来有关自行车骑行对健康的促进作用、与骑行有关的负面影响,以及国内外自行车骑行的现状,为与自行车有关的健康研究和政策制定提供理论依据。  相似文献
