An analysis of long jump performance, including both the approach and aerial phases, is applied to Bob Beamon's legendary leap at the Mexico City Olympic Games of 1968. It is shown that the combined effects of altitude and wind assistance yielded an increment in the length of the jump of about 31 cm, compared to a corresponding jump at sea level under still air conditions. The main factor is shown to be the increased sprinting speed attained under favourable conditions of wind and altitude.  相似文献

In the autumn of 1965 the British Olympic Association organised a party of doctors, scientists and athletes to investigate the effects of altitude on athletic performance. As the first major example of ‘sports medicine’ research in the history of the BOA, the Mexican Research Project is multiply symbolic. This paper explores the significance of the research project, and the rich rhetoric of ‘amateurism’ that was used both to support and attack the IOC's decision to hold the 1968 Olympic Games at altitude. As well as being a significant moment in the formation of sports medicine as a distinct specialty in the UK, the Mexican Research Project also demonstrates the tensions and trends in the international sporting and political scenes.  相似文献

ABSTRACT

The 1986 Mexico World Cup is memorialized in terms of two iconic moments produced by Argentine legend Diego Maradona’s on-field magic in the game against England – the controversial ‘Hand-of-God’ goal and the dribbling masterpiece score, unarguably considered to be the ‘Goal of the Century’. However, the World Cup with these dramatic events came in the backdrop of a tragic earthquake that devastated Mexico City taking a heavy toll of lives only a year back. While Mexico’s ruling party was accused of corruption and mismanagement in relief work, the government went ahead with the organization of the tournament. Interestingly, popular protests and movements against the government centred around stadiums such as the Estadio Azteca – the site of Maradona’s famed goals, transforming the same into sites of contestation and solidarity for many Mexicans. Writing at the time, Carlos Monsiváis, Mexico’s most notable chronicler, in his famous ‘¡¡¡Goool!!! Somos el desmadre’ (1986), captured the subversive atmosphere of these sporting venues through fan behaviour amounting to their counter-hegemonic fervour, coined ‘el desmadre’ in the chronicle. This study offers a discursive literary analysis of Monsiváis’s text and argues that both Monsi’s chronicle and his protagonists’ ‘disorderly’ behaviour served as popular discursive forces that challenged the Partido Revolucionario Institucional’s historical dominance in Mexico’s political arena.  相似文献

模拟高原训练是能够避免高原训练弊端,最大程度激发机体生理潜能,提高运动员竞技水平的有效方法。本研究尝试从设计交替训练的海拔高度着手,通过应用人工低压氧舱模拟高原训练方法,建立固定海拔2500m、4000m以及2500m~4000m交替低氧训练的动物模型,通过应用生理和生化方法对大鼠心肌相关指标进行检测及研究分析,探讨不同海拔及交替海拔训练条件下大鼠心肌抗氧化能力、有氧代谢能力等的变化,从而为运动员高——高交替训练提供参考。实验以雄性Wister大鼠为实验对象,以递增负荷跑台训练方式建立动物训练模型。将筛选后的大鼠随机分为:常氧运动组、2500m低氧运动组、4000m低氧运动组、交替低氧运动组,每组8只。第1周到第4周各组分别以不同的跑台训练模型进行训练,下高原后第5天以25m/min的速度跑至力竭。全部断头处死后,取心肌组织,分别测试各组大鼠心肌中SOD、MDA、SDH、LDH、Ca^2+-ATP酶活性的变化。实验结果表明:经过4周不同海拔低氧递增负荷跑台训练及下高原后4天的训练,交替低氧运动组大鼠心肌各指标,如SOD、SDH、Ca^2+-ATP酶活性均高于其他各组,MDA低于其他各组,LDH活性组间无显著性变化。说明交替低氧训练既可以维持较高海拔的低氧刺激,又可以减少过高海拔造成的损伤,有利于机体恢复。  相似文献

Seven elite male cross-country skiers trained for 3 weeks at an altitude of 1900 m. Haemoglobin concentration ([Hb]), haematocrit (Hct) (obtained from venous blood), maximal oxygen uptake (VO2 max) and energy expenditure during a standard submaximal workload were measured before and after training at altitude, and 1 year later while training at sea level (control). Both [Hb] and Hct increased significantly, and the skiers with the lowest initial [Hb] and Hct experienced the largest increases during training at altitude. The increase in blood lactate (BLa) concentration (using haemolysed capillary blood) during a standard submaximal exercise test was significantly lower after training at altitude than before it or 1 year later (control). A significant correlation was found between the magnitude of increase in [Hb] and Hct and the difference in the lactate response to the standard submaximal workload pre- and post-altitude training. Although VO2 max remained unchanged, lower BLa concentration during the submaximal test probably reflects an improved ability to exercise at higher submaximal workloads shortly after training at altitude compared with pre-altitude training. It is suggested that subjects with low initial [Hb] and Hct improve their aerobic performance capacity most during altitude training.  相似文献

Among the Greeks of antiquity, the mesomorphic male form had been accorded high status. Two approaches inform the modern world's thinking about ‘the body’ – that which predominates in the biological sciences (the body is a ‘machine’ that is governed by the laws of physics and chemistry) and that which has been receiving intense attention from scholars in the social sciences and humanities (the body is substantially a neutral surface upon which social and cultural values are imprinted). What occurs deep within the body's structures is immensely important but it is anatomical form that commands our attention. The mesomorphic forms that presently pervade the media insistently proclaim that muscularity defines what it is ‘to be a man’. This is by no means the first time that such a message has been heard in the modern world. Among the better educated, by the 1860s the icon of the well-muscled male – and all that this implied – was rapidly replacing the eighteenth-century ideal of manliness as one of proper stances, gestures and countenance. This found particularly powerful expression in new forms of athletics and the concept of ‘athleticism’ that emerged first in England and quickly made its way across the Atlantic, where it became linked to the rising interest in anthropometry and a host of contemporary values. Not everyone agreed, however, that athletics were beneficial; or that the tape measure and dynamometer alone could ‘take a man's measure’. This paper examines the complex matter of the reassertion of the mesomorphic male body in Britain and America from the mid-1800s to the early 1900s – about not only its physical configuration but what was inferred from and about gross anatomical form.  相似文献

Harold Maurice Abrahams (1899–1978) – the British-Jewish athlete made famous by the film Chariots of Fire – won gold for Britain in the 100 m sprint in the 1924 Paris Olympics. Far from being the ‘outsider’ depicted in Chariots of Fire, however, Abrahams’ ‘Anglicisation’ was extensive and played an important role in his life before, during and after his athletics career. Abrahams’ integration went hand-in-hand with his sporting success – something which was celebrated by British Jewry. Such was his assimilation, that by 1936 – a year when Abrahams courted controversy over his stance on the Berlin Olympics – he was criticised for having ‘lost’ all attachment to the community of his birth. In contrast to the film, where Abrahams is seen to be ‘too Semitic’, the Bedford athlete was actually ‘thoroughly Anglicised’. A desire to move into or support middle-to-upper class British society characterised Abrahams’ personal and sporting life much more so than his Jewishness. As time progressed, Abrahams’ Jewish origins meant less and less, both to Harold himself and to those around him.  相似文献

The popular tourist town of Stellenbosch in South Africa has long been a favoured training destination for European athletes during the northern hemisphere winter months. This paper considers the case study of German athletes – one of the most prominent groups to train in Stellenbosch since the early 1990s. The analysis involves the application of the concept of the Tourist Area Life Cycle (TALC) to the town’s sport tourism offering. In this regard Stellenbosch continues to experience notable demographic changes, not all of which are related to tourism. The impact of these changes is considered in the context of the factors which have historically made the town a sought-after destination for high performance athletics training camps. Consequently this paper offers an analysis of Stellenbosch’s current and future attractiveness as far as this particular dimension of sport tourism is concerned. This is an important consideration given the availability of alternative training destinations both in South Africa and internationally.  相似文献

By 1837, the sporting landscape of England was populated by a number of professional pedestrians who competed in a range of events that were extensively covered in the sporting press. These men distinguished themselves from their competitors through their use of ‘colours’ and a range of different athletic clothing. In the later stages of the nineteenth century, the dominance of the professional athlete was challenged through the formation of clubs and associations by a public-school- and university-educated middle class. The somatotype and clothing strategies of the Victorian athlete altered as a result. Their assumption of an innate physical superiority, allied to a preference for the all-rounder with his elegance and style, rather than the muscular, specialized sporting bodies of working-class professionals, were important features of an amateur ethos which drew much of its references from the Classical world. Through a discussion of how middle-class amateur athletes used Classical precedents, science and clothing to create the ‘university athlete’ and the ‘university costume’, in order to reinforce the distinctions between their own bodies and those of the professionals, this paper explores the transition from pedestrianism to organized athletics.  相似文献

This study sought to establish perceptions of elite endurance athletes on the role and worth of altitude training. Elite British endurance runners were surveyed to identify the altitude and hypoxic training methods utilised, along with reasons for use, and any situational, cultural and behaviour factors influencing these. Prior to the 2012 Olympics Games, 39 athletes and 20 support staff (coaches/practitioners) completed an internet-based survey to establish differences between current practices and the accepted “best-practice”. Almost all of the athletes (98%) and support staff (95%) surveyed had utilised altitude and hypoxic training, or had advised it to athletes. 75% of athletes believed altitude and hypoxia to be a “very important” factor in their training regime, with 50% of support staff believing the same. Athletes and support staff were in agreement of the methods of altitude training utilised (i.e. 'hypoxic dose’ and strategy), with camps lasting 3–4 weeks at 1,500–2,500 m being the most popular. Athletes and support staff are utilising altitude and hypoxic training methods in a manner agreeing with research-based suggestions. The survey identified a number of specific challenges and priorities, which could provide scope to optimise future altitude training methods for endurance performance in these elite groups.  相似文献
