Exercise testing on motorised treadmills provides valuable information about running performance and metabolism; however, the impact of treadmill type on these tests has not been investigated. This study compared the energy demand of running on two laboratory treadmills: an HP Cosmos (C) and a Quinton (Q) model, with the latter having a 4.5 times stiffer running platform. Twelve experienced runners ran identical bouts on these treadmills at a range of four submaximal velocities (reported data is for the velocity that approximated 75–81% VO_2max). The stiffer treadmill elicited higher oxygen consumption (C: 46.7 ± 3.8; Q: 50.1 ± 4.3 ml·kg^?1 · min^?1), energy expenditure (C: 16.0 ± 2.5; Q: 17.7 ± 2.9 kcal · min^?1), carbohydrate oxidation (C: 9.6 ± 3.1; Q: 13.0 ± 3.9 kcal · min^?1), heart rate (C: 155 ± 16; Q: 163 ± 16 beats · min^?1) and rating of perceived exertion (C: 13.8 ± 1.2; Q: 14.7 ± 1.2), but lower fat oxidation (C: 6.4 ± 2.3; Q: 4.6 ± 2.5 kcal · min^?1) (all analysis of variance treadmill comparisons P < 0.01). This study confirms that caution is required when comparing performance and metabolic results between different treadmills and suggests that treadmills will vary in their comparability to over-ground running depending on the running platform stiffness.  相似文献   

Annotated Bibliography     

Alison Kelly 《International Journal of Science Education》2013,35(3):417-423

This short bibliography is not supposed to be a comprehensive survey of all that has been written about gender and science. Its much more modest aim is to mention a few of the many books that have been published on this subject in recent years, and to give some indication of their contents. By doing this I hope to provide readers with a starting point from which to pursue an interest in any particular aspect of the subject.  相似文献

Credentialism,adults and part-time higher education in the United Kingdom: an account of rising take up and some implications for policy     

Alison Fuller 《教育政策杂志》2013,28(3):233-248

This paper focuses on, and helps to explain, the growing importance of higher level qualifications for adults in the UK. It highlights statistical trends in their take up of qualifications, particularly, as the result of taking part-time courses in higher education. Recent figures indicate that most part-time students at undergraduate level fund their own tuition fees: I interpret this finding as an indicator of individual demand. The article goes on to draw on a qualitative study of mature students to identify some of the issues which lie behind the statistics. I suggest that insights into the rising take up of HE can be gained from considering the backgrounds and perspectives of mature students themselves, their changing relationship to qualifying and how their return-to-study decisions relate to the contemporary socio-economic context. The paper concludes by reminding policy makers of the challenge of widening access to HE for disadvantaged groups and briefly focuses on the potential of the new foundation degree to address this issue.  相似文献   

Parental experiences of support for pupils with dyslexia: ignoring the effect on parents     

Alison Earey 《Support for Learning》2013,28(1):35-40

This article reports on research that was carried out with parents in order to understand the education system in England from their viewpoint through in‐depth, semi‐structured interviews with seven parents, who were largely sourced through a local dyslexia specialist tutor. The data were analysed by using cross‐sectional analysis in order to consider the participants' choice of words and their comparative responses to questions. The interviews probed parents for information on their experience from the initial point of concern about the child's difficulties with words, through to assessment and concerns for the future. The findings suggest that, while we live in an age of purported inclusion and equality, there are still children who experience exclusion and prejudice in education. Their experience does not match the ideal and, as a result, their parents are suffering too. The findings help to support recent research and could encourage continued improvements in the education system.  相似文献

The effects of anxiety and strategic planning on visual search behaviour     

Moran A  Byrne A  McGlade N 《Journal of sports sciences》2002,20(3):225-236

The past decade has witnessed increased interest in the visual search behaviour of athletes. Little is known, however, about the relationship between anxiety and eye movements in sport performers or about the extent to which athletes' planned and actual visual search strategies correspond. To address these issues, we conducted two studies. In Study 1, eight expert female gymnasts were presented with three digital slides of a model performing a skill that is known to be anxiety-provoking in this sport--namely, the 'back flip' on the beam. By varying the height of the beam and the presence or absence of safety mats, the slides differed in the amount of anxiety that they elicited vicariously in the viewer. In the study, the gymnasts were asked to imagine themselves in the position of the depicted model and to describe the anxiety that they felt. As they viewed the slides, their eye movements were recorded. As predicted, anxiety was associated with an increase in the number of fixations to peripheral areas. In addition, the more 'threatening' slides elicited significantly more fixations than the less feared images. In Study 2, the plans of 15 equestrian performers (5 expert, 5 intermediate and 5 novice) were elicited as they engaged in a virtual 'walk' around a computerized show-jumping course. Contrary to expectations, the congruence between intended and actual search behaviour was not significantly greater for expert riders than for the less skilled groups. Also, the fact that the top riders allocated more fixations to slides than the less skilled performers challenged the prediction that expertise would be associated with economy of visual search. Finally, as expected, the expert riders were significantly less dependent on the overall 'course plan' than the intermediate and novice equestrian performers when inspecting the fences.  相似文献
