The aim of this paper is to deepen our understanding of the inherent purpose of sports competitions. In ‘On Winning and Athletic Superiority’, Nicholas Dixon states that the central comparative purpose of an athletic contest is to determine which team or player is superior, or, synonymously, to provide an accurate measure of athletic superiority. Dixon identifies athletic skill as the standard of athletic superiority in competitive sport. However, I argue there are three separate standards of athletic superiority: the demonstration of athletic skill, the achievement of prelusory goal using lusory means, and achievement of superior formal result. This stance responds to Dixon’s argument that failed athletic contests are contests that have not fulfilled the central purpose of competitive sport, because they have been undermined by refereeing errors, cheating, gamesmanship or bad luck. I argue that a failed athletic contest occurs when any of the three standards of athletic superiority conflict. 相似文献

Twenty highly trained, eumenorrhoeic female endurance runners were studied over three consecutive menstrual cycles. Average training distance per week, total years training and mood states were recorded throughout the three cycles. Salivary progesterone and menstrual cycle diaries were recorded over the first two cycles to identify luteal phase onset and the presence of any menstrual irregularities. Saliva samples were collected daily over the third cycle for analysis of immunoglobulin A (IgA) concentration and secretion and saliva flow rate. Twoway analysis of variance (ANOVA) revealed no significant differences in mood states across the phases of the menstrual cycle ( P > 0.05). Training logs indicated that training did not alter throughout the 3 month study. One-way ANOVArevealed no significant differences in IgA concentration ( P = 0.92), secretion rate ( P = 0.84) or saliva flow rate ( P = 0.95) across the phases of the menstrual cycle. Pearson's product-moment correlation revealed no relationship between IgA concentration and progesterone between the phases of the cycle ( r = 0.39). We conclude that, in ovulatory female endurance runners whose physical and emotional stress are stable, IgA concentration is not significantly affected by fluctuations in progesterone during the menstrual cycle. 相似文献

AbstractDespite the performance concerns of dehydration in other sports, there are currently no data on the effects of rapid weight-loss on the physical and cognitive performance of jockeys in a sport-specific context. In a randomised crossover design, eight Great Britain (GB) male licensed jockeys were assessed for chest strength, leg strength, simulated riding performance (assessed by maximum pushing frequency on a mechanical riding simulator during the final two furlongs of a simulated 2 mile race) and simple reaction time after performing 45 min of exercise, during which euhydration was maintained (Control trial) or induced 2% dehydration (Rapid Weight-Loss trial). Reductions in both chest (–13.8 ± 3.03% vs. 0.62 ± 1.04%) and leg strength (–4.8 ± 4.8% vs. –0.56 ± 2.5%) were greater in Rapid Weight-Loss compared with Control (P < 0.01 and P = 0.04, respectively). Similarly, reductions in simulated riding performance were also greater (P = 0.05) in Rapid Weight-Loss (–2.8 ± 4.0%) compared with Control (–0.07 ± 1.5%), whereas there were no significant changes (P = 0.14) in simple reaction time. We conclude that a 2% reduction in body mass, as achieved by 45 min of moderate-intensity exercise undertaken in a sweatsuit (a common method of inducing acute dehydration by jockeys), significantly impairs maximum pushing frequency during a simulated race. In addition, the observed reductions in strength may also increase the occupational hazards associated with race riding. 相似文献

This article explores how a subsidiary of a multi-national enterprise (MNE) in an emerging economy embeds with multiple knowledge sources, both in its corporate network (internal) and in the host country (external), to create the capability to undertake innovative activities. Drawing on first-hand and intra-firm field evidence over the lifetime of a subsidiary in the information and communications technology industry in Brazil (1996–2009) the article finds that: (1) Within 10 years, the case subsidiary attained advanced, near-world leading innovation performance in three technological functions: project management, software engineering and product and solutions; (2) This was an outcome of how the firm simultaneously engaged in knowledge-intensive linkages based on increased frequency of use and improved quality over time, with specific internal and external counterparts; (3) However, some counterparts and linkages were more effective than others in contributing to the subsidiary's innovation performance. Drawing on a novel approach that examines the relationship between dual embeddedness and innovative performance, this article extends our understanding of embeddedness as part of knowledge-seeking strategies of MNE-subsidiaries. It also provides new insights to deepen the analysis of the nuances of subsidiaries’ multiple embeddedness, especially in emerging economies. 相似文献

ABSTRACTThis study identified clusters of adolescents who share similar cardiorespiratory fitness levels and analysed the relationships between cardiorespiratory fitness, inhibition, and math fluency in each of the clusters. The subjects were 490 high-school students aged 10–16 years. The mean age was 13.82 years (SD = 1.12). Latent class analysis identified three clusters with high, medium, and low levels of cardiorespiratory fitness. The high-fitness cluster achieved higher scores in inhibition and math fluency than the low-fitness cluster. Path analysis revealed that the influence of cardiorespiratory fitness on inhibition was non-existent in the three clusters. The effect of inhibition on math fluency was positive and significant in all three cardiorespiratory fitness levels. Cardiorespiratory fitness had a direct, positive, and significant effect on math fluency only in the high-fitness cluster. Therefore, a high level of cardiorespiratory fitness is a significant determining factor in the explanation of math fluency. These results indicate that inhibition does not mediate the relationship between cardiorespiratory fitness and math fluency. However, the benefits of cardiorespiratory fitness affect math fluency, which has important implications for the educational environment and the teaching/learning process. 相似文献
