Do stiffness and asymmetries predict change of direction performance?     

Sean J. Maloney  Joanna Richards  Daniel G. D. Nixon  Lewis J. Harvey  Iain M. Fletcher 《Journal of sports sciences》2017,35(6):547-556

Change of direction speed (CODS) underpins performance in a wide range of sports but little is known about how stiffness and asymmetries affect CODS. Eighteen healthy males performed unilateral drop jumps to determine vertical, ankle, knee and hip stiffness, and a CODS test to evaluate left and right leg cutting performance during which ground reaction force data were sampled. A step-wise regression analysis was performed to ascertain the determinants of CODS time. A two-variable regression model explained 63% (R² = 0.63; P = 0.001) of CODS performance. The model included the mean vertical stiffness and jump height asymmetry determined during the drop jump. Faster athletes (n = 9) exhibited greater vertical stiffness (F = 12.40; P = 0.001) and less asymmetry in drop jump height (F = 6.02; P = 0.026) than slower athletes (n = 9); effect sizes were both “large” in magnitude. Results suggest that overall vertical stiffness and drop jump height asymmetry are the strongest predictors of CODS in a healthy, non-athletic population.  相似文献   

A Century of British Readings of America through American Football: From the Fin de Siècle to the Super Bowl     

Iain Adams 《国际体育史杂志》2017,34(1-2):101-120

Abstract

This paper examines the development of American football and the Super Bowl in the British imagination utilizing data from the British press. Divergent images of America have been present for centuries in British minds, and American football became intertwined with these images in the nineteenth century. Initially presented as a brutalized version of British varieties of football, once American football was seen live in Great Britain and it became a familiar subject on newsreels, some commentators interpreted it as a spectacle and a synonym for American life–modern, exciting, fast, and fun. Others viewed it as a threat that could undermine the British cultural heritage. The regular broadcasting of the NFL by Channel 4, including the Super Bowl live, was a watershed with the game swiftly gaining audience numbers whilst English association football was in a dour period. The increased popularity resulted in more media coverage, including negative images of unbridled capitalism, fixed games, and drug use. By the 1990s, audience numbers declined as English football was rehabilitated and American popularity waned, mainly through unpopular foreign policies. Today, many Britons regard watching the Super Bowl in the same way as a trip to Disney, an one-day holiday to a ‘foreign’ culture.  相似文献   

Defending letters: a pragmatic response to assaults on the humanities     

Iain Hay 《Journal of Higher Education Policy & Management》2016,38(6):610-624

This paper is a mainly pragmatic response to utilitarian criticisms of the humanities. It first outlines political, public and practical fronts on which the humanities are under assault, identifying critics and their conspirators. Then, as a part of its defence of the humanities it expounds some of their central strengths. These range from the philosophical to the practical: lending critical perspectives to knowledge production, enriching lives, developing skills for uncertain and increasingly connected futures, improving science and supporting institutional income and credibility. Finally, the paper suggests that humanists must not only continue valuable conceptual and empirical disciplinary work but must add the very defence of the humanities to professional activity.  相似文献

Who cares? Gender dynamics in the valuing of extra-curricular activities in higher education     

Jacqueline Stevenson  Sue Clegg 《Gender and education》2012,24(1):41-55

Despite the assertion that higher education is becoming increasingly ‘feminised’ and that male students are the relative losers, gendered meanings continue to permeate higher education in ways that mean that the recognition of women's experiences are frequently marginalised. Our paper reports on research designed to explore student participation in extra-curricular activity from a perspective informed by a broader conceptualisation of the extra-curricular as a site of gendered, raced, and class practices intimately tied to the development of an employable self. We found that women frequently undervalue their participation and are more likely to be dismissive of extra-curricular activity as of value to their employability than men and that they rarely consider caring to be a form of capital which can be utilised or invested in to support their future employment. We argue that higher education institutions need to support students, in particular women, to recognise the value of their participation.  相似文献   

Over the Top: ‘A Foul; a Blurry Foul!’     

Iain Adams 《国际体育史杂志》2013,30(6):813-831

Part of Britain's folk memory of the First World War is of long lines of Tommies resolutely going over the top into a storm of machine gun fire and walking bravely to their deaths; following a piper if Scottish or kicking a football if English. However, rather than eventually becoming a conventional act of bravado, evidence suggests that the ‘football charge’ was limited to a 10-month period between 25 September 1915 and 1 July 1916. The most famous example is that of‘B’ Company of the 8th Battalion of the East Surreys led by Captain Nevill atthe Battle of the Somme. However, it was first performed, and possibly mostsuccessfully used, by the London Irish Rifles at the Battle of Loos on 25September 1915. This article examines what actually happened on the 25September 1915 and explores the underlying rationale of the first ‘football charge’.  相似文献
