Currently, very little is known about the impact of short- or long-haul air travel on the sleep and wellbeing of wheelchair basketball athletes. Eleven national wheelchair basketball athletes wore actigraphy monitors prior, during, and after air travel to the United Kingdom. Upon arrival, participants rated their subjective jet-lag, fatigue, and vigor. Individuals traveled to the United Kingdom from different locations in Australia, the United States, and Europe and were categorised according to travel length [LONG (up to 30.2 h) or SHORT (up to 6.5 h)]. Linear mixed models determined effects of travel length on sleep and subjective ratings of jet-lag, fatigue, and vigor. During competition, subjective fatigue and jet-lag were substantially higher (ES = 0.73; ±0.77) and (ES = 0.57; ±0.60), subjective vigor was lower (ES = 1.94; ±0.72), and get-up time was earlier (ES = 0.57; ±0.60) for LONG when compared to SHORT. Travelling greater distances by airplane had a larger effect on subjective ratings of jet-lag, fatigue and vigor, rather than sleep. Irrespective of travel group, sleep and subjective responses were compromised, reflecting the travel requirements, competition-mediated influences, and/or due to a change in environment.  相似文献   

The effect of glycaemic index of high carbohydrate diets consumed over 5 days on exercise energy metabolism and running capacity in males

Abstract

The aim of this study was to determine whether rates of total fat and carbohydrate oxidation and endurance capacity during running conducted in the fasted state are influenced by the glycaemic index (GI) of high carbohydrate diets consumed over 5 days. Nine healthy males performed three treadmill runs to exhaustion at 65% of maximum oxygen uptake ([Vdot]O_2max): after a habitual diet (control trial), after 5 days on a high carbohydrate/high glycaemic index diet, and after 5 days on a high carbohydrate/low glycaemic index diet in randomized counterbalanced order. No significant differences in rates of fat and carbohydrate oxidation, concentrations of plasma insulin, glucose, non-esterified fatty acids and glycerol, or time to exhaustion were observed between the high carbohydrate/high glycaemic index and high carbohydrate/low glycaemic index trials. Compared with the control trial, the concentration of plasma glycerol and rate of fat oxidation were lower (P < 0.05) and the rate of carbohydrate oxidation higher (P < 0.05) in both the high carbohydrate/high glycaemic index diet and high carbohydrate/low glycaemic index trials during the run to exhaustion. In conclusion, the extent by which a high carbohydrate diet consumed over 5 days reduces rate of fat oxidation during subsequent running exercise in the fasted state is not influenced by the glycaemic index of the diet.  相似文献   

An investigation into breast support and sports bra use in female runners of the 2012 London Marathon     

Nicola Brown  Jennifer White  Amanda Brasher  Joanna Scurr 《Journal of sports sciences》2013,31(9):801-809

Abstract

Although it is acknowledged that appropriate breast support during exercise is important, no published literature has assessed breast support usage in a cohort of female marathon runners. This study aimed to identify sport bra use and perceived importance of sports bra use in female marathon runners. Bra satisfaction, incidence of bra related issues and factors that influence the appropriateness of sports bras were also investigated. A 4-part, 30-question survey was administered to 1397 female runners at the 2012 London marathon registration and via an online survey. In total 1285 surveys were completed. Sports bra use and its perceived importance was high, however was lower in moderate compared to vigorous activity, and lower in participants with smaller breasts. Seventy-five per cent of participants reported bra fit issues. The most common issues were chaffing and shoulder straps digging in, with a higher incidence of issues reported by participants with larger breasts. Use of professional bra fitting was low, and perceived knowledge of breast health was poor. Engagement with sports bra use is high although sports bra design could be improved to alleviate bra fit issues experienced by female runners. Educational initiatives are needed to ensure females are informed regarding the importance of breast support and appropriate bra fit during activity.  相似文献   

Intercultural PhD supervision: exploring the hidden curriculum in a social science faculty doctoral programme     

Joanna Kidman  Catherine Manathunga  Sue Cornforth 《高等教育研究与发展》2017,36(6):1208-1221

International knowledge markets rely heavily on a ready supply of highly mobile doctoral students, many of whom are from the global South, to bring in revenue. The supervision of these PhD students, however, can reproduce neo-colonial knowledge relations, often in subtle ways. In settler nations, international PhD students may find that they are assigned subaltern status in their university departments and this can have a significant impact on their learning. This paper explores the experiences of a group of international PhD students in a social science faculty in a New Zealand university during the first two years of their doctoral studies. It examines how they responded to the displacement of their cultural values and priorities, the way they navigated intercultural engagements with supervisors, and their ensuing relationships with indigenous and ethnic allies in the faculty. Despite considerable pressure to conform to the dominant modes of academic knowledge production that characterise universities in settler nations, it is concluded that international students find ways of speaking out, often in highly coded forms, that complicate their subaltern academic status.  相似文献

Supporting Teachers’ Use of Technology in Science Instruction Through Professional Development: A Literature Review     

Tara E. Higgins  Michele W. Spitulnik 《Journal of Science Education and Technology》2008,17(5):511-521

Professional development is critical in supporting teachers’ use of technological tools in classrooms. This review of empirical research synthesizes the effective elements of professional development programs that support science teachers in learning about technology integration. Studies are examined that explore how professional development supports technology use within inquiry-based and traditional science instruction. Implications for future research are discussed in four areas: understanding and building on teachers’ beliefs about science and technology; supporting teacher learning by supporting teachers’ examination of students’ work; using technology to support teacher communities and social networks; and sustaining teachers’ learning beyond formal professional development programs.

Student perceptions of how critical thinking is embedded in a degree program     

Joanna Tapper 《高等教育研究与发展》2004,23(2):199-222

Critical thinking is a highly valued outcome of university study, although its nature is difficult to define. Most students are not directly taught critical thinking, but are expected to display it in at least some of their assignments. We do not know much about student perceptions of their development as critical thinkers in their degree programs. This paper presents research into student perceptions of instruction in critical thinking and aspects of its development as they study in an undergraduate degree program in agriculture. Twenty‐one students across four years of study were interviewed. They received direct instruction in critical thinking only in the first year of study, and the literature review emerged as a key genre in which critical thinking was perceived to be important by later‐year students. The final sections highlight the importance of considering the disciplinary contexts in which students develop their critical thinking, and of preparing them for transfer to post‐study contexts.  相似文献

Teaching of Mandarin in an English Comprehensive School: A case study     

Louise T. Higgins  Kerry Sheldon 《Educational studies》2001,27(2):109-127

A group of English children in a rural comprehensive are learning Mandarin, taught by a Chinese teacher. This article describes the background to this development and follows three cohorts of students, giving the pupils' views about learning Chinese and why they chose it. As a psychologist who has interests in education and who is also a part-time student of Chinese, the author welcomed the chance to share the pupils' experience. In the final cohort, sensation-seeking tendencies and intellectual achievement responsibility were investigated as personality traits which may influence a child's choice of foreign language study.  相似文献   

Differences and impacts through action learning     

Joanna Kozubska 《Action Learning: Research and Practice》2012,9(2):145-164

Here, we argue that action learning (AL) has been evolving into different variations, whose respective advocates appear to concentrate on one of the several components inherent in Revans’ formulation of AL as L?=?P?+?Q. They do this – sometimes inappropriately – to the virtual or relative exclusion of other aspects, and this has consequences for the outcomes and impact of the AL process. In an attempt to delimit the boundaries between various versions and indeed to identify what Johnson [2010. A framework for the ethical practice of action learning. Action Learning: Research and Practice 7, no. 3: 267–283] called ‘inauthentic’ AL, we have been developing our ideas for a scanning device or framework. We refer briefly to some of the theoretical underpinnings of this framework. We then introduce a fresh taxonomy to explain and illustrate features of five principal variations of emphasis in AL that we have identified. The aim of this framework is to help stakeholders to work towards selecting and co-creating the most appropriate variation of ‘authentic’ AL to suit their unique set of circumstances at any given time. We outline the likely outcomes of each respective variation if taken to extremes and conjecture about their implications. This taxonomy should also help one to reduce the mystique and confusion that often surround AL while acknowledging its complexity. We suggest that by taking advantage of insights provided by this framework, purchasers and potential AL set members in particular are more likely to participate in learning conversations that lead to more informed decisions and actions to address or adjust their respective interests and needs. In conclusion, we identify some areas for further research and development.  相似文献
