Expertise in sport can appear so extraordinary that it is difficult to imagine how “normal” individuals may achieve it. However, in this review, we show that experts in the sport of orienteering, which requires on-foot navigation using map and compass through wild terrain, can make the difficult look easy because they have developed a cognitive advantage. Specifically, they have acquired knowledge of cognitive and behavioural strategies that allow them to circumvent natural limitations on attention. Cognitive strategies include avoiding peaks of demand on attention by distributing the processing of map information over time and reducing the need to attend to the map by simplifying the navigation required to complete a race. Behavioural strategies include reducing the visual search required of the map by physically arranging and rearranging the map display during races. It is concluded that expertise in orienteering can be partly attributed to the circumvention of natural limitations on attention achieved via the employment of acquired cognitive and behavioural strategies. Thus, superior performance in sport may not be the possession of only a privileged few; it may be available to all aspiring athletes. 相似文献

AbstractThe purpose of the present study was to identify which game-related statistics discriminate winning and losing teams in men’s and women’s elite wheelchair basketball. The sample comprised all the games played during the Beijing Paralympics 2008 and the World Wheelchair Basketball Championship 2010. The game-related statistics from the official box scores were gathered and data were analysed in 2 groups: balanced games (final score differences ≤12 points) and unbalanced games (final score differences >13 points). Discriminant analysis allowed identifying the successful 2-point field-goals and free-throws, the unsuccessful 3-point field-goals and free-throws, the assists and fouls received as discriminant statistics between winning and losing teams in men’s balanced games. In women’s games, the teams were discriminated only by the successful 2-point field-goals. Linear regression analysis showed that the quality of opposition had great effects in final point differential. The field-goals percentage and free-throws rate were the most important factors in men’s games, and field-goals percentage and offensive rebounding percentage in women’s games. The identified trends allow improving game understanding and helping wheelchair basketball coaches to plan accurate practice sessions and, ultimately, deciding better in competition. 相似文献

Designing tomorrow’s snow park jump 总被引：1，自引：1，他引：0
Recent epidemiological studies of injuries at ski resorts have found that snow park jumps pose a significantly greater risk
for certain classes of injury to resort patrons than other normal skiing activities. Today, most recreational jumps are built
by skilled groomers without an engineering design process, but the Snow Skiing Committee (F-27) of the American Society for
Testing and Materials is considering the inclusion of recreational jumps in their purview which may lead to a greater role
for engineering jump designs in the US in the future. Similar efforts are underway in Europe as well. The purpose of this
work is to review the current state of the science of snow park jumps, describe the jump design process, and outline the role
that modelling will play in designing tomorrow’s snow park jumps. 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

This study investigated the evolution of physical and technical performances in the English Premier League (EPL), with special reference to league ranking. Match performance observations (n = 14,700) were collected using a multiple-camera computerised tracking system across seven consecutive EPL seasons (2006–07 to 2012–13). Final league rankings were classified into Tiers: (A) 1st–4th ranking (n = 2519), (B) 5th–8th ranking (n = 2965), (C) 9th–14th ranking (n = 4448) and (D) 15th–20th ranking (n = 4768). Teams in Tier B demonstrated moderate increases in high-intensity running distance while in ball possession from the 2006–07 to 2012–13 season (P < 0.001; effect size [ES]: 0.68), with Tiers A, C and D producing less pronounced increases across the same period (P < 0.005; ES: 0.26, 0.41 and 0.33, respectively). Large increases in sprint distance were observed from the 2006–07 to 2012–13 season for Tier B (P < 0.001; ES: 1.21), while only moderate increases were evident for Tiers A, C and D (P < 0.001; ES: 0.75, 0.97 and 0.84, respectively). Tier B demonstrated large increases in the number of passes performed and received in 2012–13 compared to 2006–07 (P < 0.001; ES: 1.32–1.53) with small-to-moderate increases in Tier A (P < 0.001; ES: 0.30–0.38), Tier C (P < 0.001; ES: 0.46–0.54) and Tier D (P < 0.001; ES: 0.69–0.87). The demarcation line between 4th (bottom of Tier A) and 5th ranking (top of Tier B) in the 2006–07 season was 8 points, but this decreased to just a single point in the 2012–13 season. The data demonstrate that physical and technical performances have evolved more in Tier B than any other Tier in the EPL and could indicate a narrowing of the performance gap between the top two Tiers. 相似文献

It seems David Beckham is destined to be judged more according to his celebrity status than to his soccer skills. Even as a soccer player occupying one of the most mythic positions on the pitch, the winger, Beckham has constantly fallen short to the inevitable (but also unfair) comparisons with Cristiano Ronaldo, Ryan Giggs, Luis Figo and even earlier prototypes such as George Best or Raymond Kopa, whose basic qualities consisted in dribbling, speed and goal line crosses. The problem with these comparisons is that Beckham, at the outset, is categorized as a winger when he in fact was, initially, a central midfielder. However, because Beckham brings along some of the virtues as a central midfielder – passing skills and combative tackling – when he migrates from the centre of the field to the right, he is able to invent a completely new type of winger. Overall speaking, Beckham fuses a Bergsonian epic quality of durée and accumulating presence with a Nietzschean lyric quality of unexpectedness and abruptness. More specifically, what sets Beckham apart and secures him a seat in the Pantheon of soccer’s great innovators are timing (‘early on and unexpectedly’), sense of spacing (‘halfway’) and the fusion of Euclid and Einstein (‘curled crosses with extreme precision’). 相似文献

AbstractIn the second half of the nineteenth century, Amsterdam underwent important changes in its economic, social, and cultural life as the city entered what is often referred to as its ‘Second Golden Age’. Old elites gave way to new and a new more entrepreneurial culture emerged focused on mass, visible, and consumable activities, including sport, in which the body played a central role. This was especially apparent from the late 1870s and 1880s when spatial changes within the city helped to ensure that sport was increasingly the location for new kinds of associational activity and the development of new products, all underpinned by the potential for profit. Entrepreneurs such as Perry & Co., De Gruyter, and the Amsterdamsche Sport-Club were able to effect strategic combinations between the new body culture and consumerism, producing a range of new products and exploiting new technologies to create new markets. In seizing these opportunities, Amsterdam's entrepreneurs were also reproducing the concept of the trainable, measurable, and consumable body. 相似文献

AbstractThrough reviewing the 1993 Shanghai East Asian Games, the 2001 Beijing Summer Universiade and the 2014 Nanjing Summer Youth Olympics, this paper provides an in-depth account of how the organization and celebration of China’s international sporting events were decisively leveraged to improve Beijing’s chance of success in the three Olympic bids, respectively for the 2000 Summer Games, the 2008 Summer Games, and the 2022 Winter Games. The findings show China’s nationwide determination to entitle the capital city to hold the Summer and Winter Olympics as well as the synergy of its central and local authorities in handling international sporting affairs. They also reveal the keys that enable China to have become one of the most reliable spots on the planet for staging sporting mega-events and to gain long-lasing prestige in the global sports community. 相似文献

This article examines issues of gender justice within men’s netball and mixed-gender indoor netball in New Zealand, primarily from philosophical and social policy-based perspectives. While netball has historically reflected and reinforced appropriate ideas of female physicality, in the early 1980s, the new and more radical New Zealand Men’s Netball Association (NZMNA) welcomed openly transgender female players. Although the association subsequently took a heteronormative turn, independent for-profit mixed-gender indoor netball have also provided somewhat transgender-inclusive spaces. After discussing feminist debates about mixed-gender sport including netball specifically, this article argues that there are good reasons to support mixed-gender indoor netball. It also argues, however, that this should be done while also recognising both NNZ’s defensive ‘voluntary segregation’ of women’s netball and the unfortunate decline of the early (more radical) NZMNA. The article also discusses some important criticisms of such a policy. 相似文献

This paper argues that human psychological resilience is a central virtue in sport and in human life generally. Despite its importance, it is an overlooked virtue in philosophy of sport and classical and contemporary virtue theory. The phenomenon of human resilience has received a great deal of attention recently in other quarters, however. There is a large and instructive empirical psychological literature on resilience, but connections to virtue theory are rarely drawn and there is no agreement about what the concept refers to. This paper attempts to clarify the concept of resilience and explain how it fits into and supports a traditional Aristotelian conception of virtue. It shows how resilience figures centrally in sport and can extend and enrich our understanding of virtue and success in sport and of sport's internal values. The investigations into the nature of resilience in sport can also help us to understand better sport's contributions to human culture and well-being. 相似文献

In this review, we critically evaluate the scientific research into the morphology and physiology of cricket batsmen. We consider all aspects of the motor control of this skill, in the context of research into dynamic interceptive actions, the biomechanics (kinematics and kinetics) of the various phases of batting strokes and injuries to batsmen. Some attention is also devoted to batting equipment and to psychological factors in batting. Because of the lack of published scientific research into women's cricket, this review focuses on the men's game and covers research on batsmen of various playing standards. For the future, we see as a high priority research into injury mechanisms, rather than simple injury statistics, and the role of cricket equipment design in injury prevention. A second priority is for multi- or inter-disciplinary research, linking the biomechanics of batting to the underlying motor control of the movements and the effect of environmental information. Biomechanical studies of the variability of the batsman's movements are needed, and these should be related to the compensatory variability proposal of ecological psychology. Clearly, there is also a need for scientific research into batting in women's cricket, which has been inadequately researched to date. 相似文献
