通过在多年的标枪教学实践中的归纳总结、观看录像、查找资料法等方法对标枪飞行弧线与最后用力技术群关系的分析研究.根据标枪出手后在空中出现不同的飞行和滑翔形式,把标枪的整个飞行轨迹分成了4种不同的类型,结果是不同的飞行轨迹同最后用力瞬问姿势动作密切相关.现代标枪的特性决定了只有选择适合现代标枪飞行轨迹类型的投掷技术,才能使标枪投掷的更远,为对标枪的教学与训练提供更有价值的参考. 相似文献

1 问题的提出 由于成年男子800克标枪重心的前移及规格的改变,使现行700克标枪的性能与新型800克标枪存在着很大的差别。700克标枪的重心要求和设计都是按过去老式800克标枪设计的。所以,700克标枪的性能很难适应现行标枪(800克新枪),对少年 相似文献

Lacrosse has long been considered Canada's national sport and, beginning in the latter half of the nineteenth century, became tied to the nationalist ambitions that sought to promote a national identity through the ‘creation’ of a uniquely Canadian game. Popular in the decades prior to the turn of the twentieth century, lacrosse in Alberta began to decline after the First World War, becoming a marginal sport played only in the province's larger cities. A brief and unexpected revival of lacrosse occurred in two communities, Edmonton and Lethbridge, in the 1920s championed by a nativist organization, the Native Sons of Canada (NSC). For this group lacrosse represented a natural means to promote their ‘Canada First’ ideology to young male Albertans. In Edmonton, the Native Sons sponsored a senior men's lacrosse team that garnered some local and regional attention, while attempts by the Lethbridge assembly to promote youth lacrosse in 1927 were largely unsuccessful. Despite the continuing affinity between Canadian nationalism and lacrosse, the NSC were ineffective in their efforts to revive interest in the sport. The ‘national’ game did not provide nativists in Alberta the platform they sought to promote their nationalist agenda. 相似文献

从脚步动作上分,进攻假动作有左右移动、前后移动和原地碾转;从上体姿态上看,进攻假动作有左右虚晃、前后虚晃、上下虚晃和转体。防守时的策略,一要注意分配合理,及时洞察对手进攻意图;二要不时运用防守假动作干扰对手;三要与同伴的协防相结合。灵敏、协调是一切假动作的基础。针对普通大学生,应首先在腰部的柔韧性和移动技术的灵活性以及单个技术的熟练性上下功夫。 相似文献

ABSTRACT British actress, Sarah Mayer’s light and racy attitude to the bathing arrangements after judo training sessions in Japan in the 1930s belies a dangerous and volatile time in Anglo-Japanese relations. This paper seeks to demonstrate that her pioneering achievement as the first western woman to be awarded a black belt in Japan, was part of the political machinations of the day. As Japan campaigned for the 1940 Tokyo Olympic Games, the use of Mayer’s image and persona to promote not only nationalism, but internationalism and modernity, was related to a rift forming in the League of Nations. Mayer’s story shows the use of sport as a political tool. Originally developed as part of a wider doctoral thesis on the contribution of Mayer to the history of judo, and using mainly primary source research, this article charts Mayer’s life leading up to and following her time in Japan, detailing how her position in society and her work as an actress and theatre entrepreneur impacted on the development of women in judo. Understanding the history of women in judo is integral to an understanding of the sport itself and this paper hopes to contribute to the scant literature in the field. 相似文献

Writing over a decade ago, Penney and Harris examined extra-curricular physical education (ECPE) provision in state schools in England and Wales and focused, in particular, on issues of inclusion, equality and equity. They concluded, among other things, that ECPE provision was highly gendered, characterised by a disproportionate emphasis on traditional team games and competitive sport and provided a limited number of opportunities to only a minority of pupils. Although Penney and Harris were less concerned with reflecting upon how the content, organisation and delivery of ECPE may come to impact the involvement and experiences of young disabled people and those with special educational needs (SEN), their analysis nevertheless has important implications for understanding this largely under-explored and neglected aspect of research. In this paper, therefore, we draw upon some key aspects of Penney and Harris's analysis to examine the extent and ways in which physical education (PE) teachers have endeavoured to incorporate disabled pupils and those with SEN in ECPE. In particular, by drawing upon the findings of a study conducted with 12 PE teachers working in five secondary schools in north-west England, the central objectives of this paper are to: (i) examine the ways and extent to which teachers have endeavoured to incorporate young disabled people and pupils with SEN in ECPE; and (ii) explore the extent to which the content, organisation and delivery of ECPE impacts on pupils’ involvement and experiences. The findings suggest that the trend towards including disabled pupils and those with SEN in mainstream schools has not radically altered the content, organisation and delivery of ECPE which, according to PE teachers, continues to be heavily dominated by competitive team sports that retain a strong emphasis on performance, excellence and skills. This provision, it is claimed, appears to have done more to reduce, rather than enhance, the opportunities for pupils to participate in the same activities and to the same extent in ECPE than they might have done in the special school sector. Indeed, when compared to their non-disabled peers, some disabled pupils and those with SEN typically tended to be provided with a limited and somewhat narrow range of sports and physical activities in which to participate. Teachers also suggested that some pupils rarely participated, if at all, in ECPE and, in some cases, they were often taught separately from other pupils in clubs and teams that were developed specifically for them in an effort to cater more adequately for their needs and abilities. It is concluded that until PE teachers and schools are willing and/or able to bring about desired change in the content, organisation and delivery of ECPE, rather than developing more inclusive and non-segregated forms of provision, teachers in many schools will be constrained and/or inclined to continue providing programmes that, in effect, continue to provide what Penney and Harris call ‘more of the same for the more able’ pupils in ECPE. 相似文献

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. 相似文献
