This study estimated the expected point value for starting possessions in different field locations during rugby league match-play and calculated the mean expected points for each subsequent play during the possession. It also examined the origin of tries scored according to the method of gaining possession. Play-by-play data were taken from all 768 regular-season National Rugby League (NRL) matches during 2010–2013. A probabilistic model estimated the expected point outcome based on the net difference in points scored by a team in possession in a given situation. An iterative method was used to approximate the value of each situation based on actual scoring outcomes. Possessions commencing close to the opposition’s goal-line had the highest expected point equity, which decreased as the location of the possession moved towards the team’s own goal-line. Possessions following an opposition error, penalty or goal-line dropout had the highest likelihood of a try being scored on the set subsequent to their occurrence. In contrast, possessions that follow an opposition completed set or a restart were least likely to result in a try. The expected point values framework from our model has applications for informing playing strategy and assessing individual and team performance in professional rugby league. 相似文献

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

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

Online media is a boon to fandom. It provides mountains of information for the devout follower, while it also provides the opportunity to create and share content. The internet allows fans to transcend geographical barriers to form communities that could not otherwise exist. One particular group of A.S. Roma fans show how fans can use the ‘placeless' internet to invigorate a connection to place. They use their website in conjunction with meeting at the stadium and at other places in real life. The website provides the glue to their geographically dispersed set of Romans. The web is another tool that serves the social needs of fans. 相似文献

This essay delves into the theoretical and practical dimensions of political expression at the stadium. While previous chapters are organized around the form of media, this essay considers the breadth of media put to use to convey political sentiments. While the notion of sport as apolitical has surface appeal, the stadium has always been political, and provided that sport continues to aggregate tens of thousands of fans in an enclosed space, there is little hope of eliminating politics. The stadium offers the chance for average citizens to gain a voice and, I argue, the stadium is an important part of the public sphere. The chapter considers how the stadium is used for dissent in several contexts. In Italy, the stadium has long been a site of political expression while more recently, in Cairo and Istanbul, football fandom has provided the tools to directly confront the state. 相似文献
