大负荷专项训练对散打运动员氧化应激及红细胞影响研究

目的:分析探讨一次大负荷专项训练对不同运动水平男子散打运动员氧化应激的影响。方法:用生化测定方法检测受试者一次大负荷专项训练前后游离血红蛋白和丙二醛、超氧化物歧化酶含量的变化。结果:大负荷散打专项训练可引起血液氧化应激水平的提高,同时导致大量红细胞破裂、溶血,这可能是造成运动性红细胞损伤、运动性疲劳及溶血性贫血的重要机理。优秀散打运动员比一般散打运动员过氧化与抗氧化系统功能更强,认为运动性氧化应激可能是机体的一种适应性机制。

Promoting athlete welfare: A proposal for an international surveillance system

Efforts to ensure the welfare of athletes have long existed in sport but have heightened recently across numerous countries in response to shocking revelations of sexual abuse in sport. Cases such as the sexual abuse of female gymnasts by a team doctor in the U.S. and sexual abuse of male footballers by a coach in the U.K. have drawn significant attention and scrutiny by stakeholders in sport and the public alike. These and other cases indicate that in spite of existing athlete welfare policies, educational programmes, and efforts to ensure compliance, numerous athletes were abused, the perpetrators were permitted to continue over an extended period of time, and some adults knew of the abuses and were complicit in failing to intervene. In this article, the authors use Bronfenbrenner’s Ecological Theory to review the current landscape with respect to initiatives to prevent and address athlete maltreatment at each level of the theory. The authors also propose that to advance athlete welfare, more attention needs to be devoted to the development of interventions at the macrosystem or international level. Using Bruno Latour’s concept of the oligopticon (1992) an argument is forwarded to create an international surveillance system to promote athlete welfare.     

Managing sport for health: An introduction to the special issue

Sport is often viewed as vehicle to achieve positive health outcomes. While sport's potential to contribute to health is rarely disputed, sport is not always managed in ways that specifically prioritise health objectives, and evidence regarding sport's contribution to health has been inconsistent to date. This special issue was designed to advance a research agenda in relation to the management of sport for health. Articles published in the special issue examine sport management practices that impact health, both positively and negatively. The authors identified three overarching themes, with respect to how sport can be managed towards the achievement of health outcomes: sport should be aligned with community needs and should be empowering; sport should be adaptable and evolving to ensure sport culture values health; and, sport organisations should leverage partnership for health to promote organisational sustainability. In future research, scholars are encouraged to further examine the three identified themes and expand on other findings presented in the special issue, towards a stronger evidence base in relation to the management of sport for health. Opportunities exist to continue to advance knowledge regarding the potential for management strategies, models, and practices to lead to positive-and importantly, negatives-health outcomes through sport. If sport management scholars and practitioners are to meaningfully contribute to health agendas, health objectives must play a central role in reshaping sport systems and strategies toward the achievement of such outcomes.

A Kinematic Analysis of the Baseball Batting Swings Involved in Opposite-Field and Same-Field Hitting

Abstract

The purpose of this study was to examine the mechanics of hitting a baseball to the same and opposite fields. Twenty male subjects were assigned to one of two groups according to their baseball hitting abilities. Each subject performed as many trials as were necessary to successfully hit a pitched ball three times to both the same and opposite fields. Each trial was filmed from above. No significant interactions (p < 0.05) were found between subject groups and field hits with selected temporal and kinematic parameters entered as dependent variables. Significant differences (p < 0.05) were found between body landmark and segment component displacements and velocities at the instant prior to ball contact. The maximum resultant linear and angular speed of the examined body and bat landmarks were found to occur prior to ball contact. Based on the results of the study it was concluded that no interactions exist between hitting ability and hitting technique when hitting to defined field areas and that differences in the mechanics of hitting to defined areas are due in part to: (1) differences in the angular displacements of the left wrist and left elbow joints and (2) differences in the temporal characteristics of the swings.

中国职业足球“供给侧改革”的理论源流、选择动因与路径研究

梳理供给侧结改革的理论源流，分析中国职业足球选择供给侧改革的现实动因，提出推进中国职业足球供给侧改革的路径与措施。研究发现，在需求侧，中国职业足球国内消费市场潜力巨大，但当前消费水平相对较低，市场开发相对滞后；可投资领域众多，而实际投资结构失衡，且收益低、风险高；产品出口初现端倪，但规模和竞争力尚显不足。在供给侧，职业足球人才匮乏导致产品供给失效，足球政策利好引致资本供给失衡，利益牵涉致使制度供给失准。分析认为，应借助于供给侧改革充分发挥市场在中国职业足球资源配置中的决定性作用，规范和强化相关制度与政策的调节和引导作用，提升制度供给、资本供给的准确性和有效性，通过改革和创新来推动中国足球职业化进程，实现职业足球人才供给的可持续发展，提升职业足球产品供给质量和相关服务水平，逐渐满足球迷不断提高的消费需求。

Chinese Desires? Olympism and Dominance,Guangzhou and Missed Opportunity,Major Leagues and Isolation on the Pacific Rim

Understanding the situation of China's self-promotion via Olympism requires us to connect two patterns. China is successful at Guangzhou and in Beijing Games at sponsoring and competing in Olympic-style sports festivals, but also surrounded by highly popular professional team sport leagues in baseball, rugby and cricket from Japan to India. China is successful in the promotion of its new capitalist economy but is critically short of energy sources and its aggressive diplomacy in pursuit of energy by land and sea has led to confrontations from Japan to Burma and even to the US ‘pivot’ to Asia. Review of theories of situation demonstrates that while a Debord-style spectacle theory might seem to explain the sporting spectacles and a realism in the tradition of Clausewitz might seem suited to the military situation, in fact approaches to situation combining realist and constructivist elements are stronger; a Deleuzian emphasis on will to power needs to be supplemented by Weberian attention to ends and ideas. Neither pattern explains the other; they connect. China makes history and its internal debates over state and middle class values can be tracked observing promotion of professional team sport in urban China and the scale of state sponsorship of Olympic-style games.
