过度训练对大鼠心肌线粒体内钙、MDA及磷脂酶A2的影响   总被引:3,自引:0,他引:3  
为了研究过度训练状态下心肌组织损害的变化规律,采用建立一般训练和过度训练大鼠模型,应用形态学手段和分子生化技术,对训练后两组大鼠心肌线粒体内钙含量、脂质过氧化反应产物丙二醛(MDA)、谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)、心肌组织匀浆内酸性磷酸酶(Acid Phosphatase,ACP)和β莆萄糖醛酸酶(Beta-glucronidase)、磷脂酶A2(PLA2)等指标做了定位和定量研究。结果表明,第4周末,一般训练组和过度训练组大鼠心肌线粒体内钙含量、MDA和GSH-Px、SOD、PLA2活性和心肌ACP、β-葡萄糖醛酸酶的活性未见异常改变明显降低;第8周末,心肌ACP和β-葡萄糖醛酸酶明显增加。结果提示过度训练后心肌线粒体的结构和功能产生了明显变化,这些变化可能是引起过度训练状态下心肌损伤的主要原因。  相似文献

马拉松·整体设置·体力波·滚动式   总被引:1,自引:0,他引:1  
对马拉松训练,必须赋予"整体设置"的眼光."整体设置"眼光的焦点,在于能量榆出功率水平.马拉松水平的表达,在时间过程中,应该以"体力波"(完整的训练阶段)作为基本环节.早先的马拉松进步,是."间断式"的;如果由"间断式"转变为"滚动式",将实现马拉松训练发展史上的一个跨越.  相似文献

The article is intended to reveal important similarities between fiction and sport. I build on Jonathan Gottschall’s discussion in The Storytelling Animal: How Stories Make Us Human by celebrating the significance of stories and their ‘witchy power’ and by examining factors that demonstrate similarities between fiction and sport. I suggest that an unmistakable semantic, structural, and cultural kinship exists between the two. This argument requires a discussion of play theory, play resources and constitutive rules, the semantic power of problems and the uncertainty they produce, and the role of ‘frames’ in bringing problems to life. I conclude by noting the unique frame capabilities of ‘the big game’ and zero-sum dichotomous sporting motifs.  相似文献

This essay describes a plan for investigating the cultural meanings of hockey in Canada by examining media narratives of high-level amateur and professional hockey during the late nineteenth and early twentieth centuries. In particular, this project analyzes English Canadian newspaper coverage of Stanley Cup games between 1894 and 1907, as well as the telegraph reconstructions that enabled fans to share a simultaneous experience of distant games. Media coverage of hockey brought Canadians into local and national communities of interest, while constructing narratives of manhood, regional rivalry, and civic pride. Hockey played a significant role in the construction of gender and class identities, and in debates about amateurism, professionalism, and community representation in sport. By exploring key issues related to media, gender, and community identities in early hockey, this research addresses important gaps in the study of sport history and the analysis of sport and Canadian popular culture.  相似文献

Abstract

Stephen Hardy’s tripartite sports product (1986), as subsequently refined by George Sage (2004) and recently reconfigured by Wray Vamplew (2018), remains the starting point for any study of entrepreneurship in and around sport. Recent work in business history, especially Daniel Wadhwani and Christina Lubinski’s advocacy of ‘new entrepreneurial history’ (2017), also has implications for sports historians. These perspectives are crucial for identifying and exploring some key characteristics of entrepreneurship, here defined as an essentially creative process during which opportunities are enacted and developed rather than discovered and exploited. Emphasis is placed on innovation and on how new combinations are effected. A provisional taxonomy of new combinations is developed and three principal categories – parasitic, strategic, and symbiotic – are suggested, each relating to the tripartite sports product in a different way. These abstract formulations are illustrated by examples drawn mainly form the business history of late-nineteenth and early twentieth-century sport.  相似文献

成功的训练不仅涉及到过负荷,同时必须避免大量过负荷练习与不充分恢复相结合。运动员可经历短期运动成绩下降。这一功能性过量训练在恢复后,可提高运动成绩。当训练和恢复之间平衡被破坏,可发生非功能性的过量训练(NFOR)。区分NFOR和过度训练综合症非常困难(OTS),取决于临床结果和排除诊断。诊断OTS的关键词是"延长性的不良适应",以及生物、神经生化和激素调节上的机制。普遍认为OTS症状比NFOR严重,如疲劳、成绩下降、情绪障碍。尽管目前没有单一的标志物可检测OTS,定期监测运动成绩、生理、生化、免疫和心理上的指标可能是最好的策略:发现不能够应对训练应激的运动员。  相似文献

Abstract

The concept of women engaging in physical recreation was anathema to late nineteenth-century Mexican society. While underlying scepticism continued throughout the decades that followed, post-Revolutionary reforms provided a surprisingly open arena within which both men and women could practice sport. We analyze how the issue of gender influenced these reforms and the degree to which this affected popular participation in sports. Identifying media coverage as a barometer of broader society’s perceptions of female sporting activity, we consider the salient trends in the Mexican press, how these changed over time, and the ways in which female journalists approached women’s sport. Our findings suggest the need for caution in leaping to gender-based assumptions and provide evidence that, in some respects, male journalists became more enlightened than their female counterparts in confronting underlying prejudices.  相似文献
