ABSTRACT

Introduction: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. Methods: The validated questionnaire, ‘Low Energy Availability in Females Questionnaire’ was distributed online (November 2016–February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of?≥?8 and were grouped into: (i) international; (ii) provincial/inter-county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. Results: Risk of LEA was identified in 40% (n?=?331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12–2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20–2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81–5.02). Conclusion: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required.  相似文献

李少兰 《广州体育学院学报》2017,37(1):51-53

国际政治与经济发展的种种变革促成了今天经济的全球化发展态势,在高度发达的互联网技术以及文化多元化的国际文化价值观的双重影响下,经济全球化已从一种“趋势”发展成为了今天的显示,这种新态势迫使各国都在开发市场的同时,努力输出自己的产业,提升自身在全球化中的影响力.我国体育科技发展水平在举国体制的支撑下迅速发展,如同我国竞技体育水平一样,在很多方面处于国际领先地位.以人才和软科学输出为先导,带动实体产品的输出,同时,加强国内和国际市场的统一开发与把握,是我国体育科技产业海外发展的可行之路.  相似文献   

English in Education: the first fifty years     

John Hodgson  Sarah Wilkin 《English in Education》2014,48(3):196-229

On the fiftieth anniversary of the first publication of English in Education, this article reviews the journal's contribution to research and practice in the teaching of English. A thematic analysis based on close study of a sample of volumes is arranged chronologically (to show the development of ideas and practices) and thematically in terms of language mode (speaking; writing; reading, including new technologies). The article argues that the journal archive can shed light on the educational past in ways that can effectively inform the educational present and help to set agenda for the future.  相似文献   

Exploring an intervention’s impact on everyday school activities     

Marianne Björn  Idor Svensson 《Support for Learning》2021,36(1):5-19

The focus of this paper is on a group of pupils with reading and writing difficulties who have been participating in an intervention study using assistive technology. That intervention study contained supervised training sessions with reading and writing tasks using an iPad with special supportive applications. The current study is a qualitative investigation of whether there has been any transfer from the intervention, to the pupils’ everyday school activities. Interviews with pupils and their teachers and observations during classroom lectures have been used to collect data. The results show that the pupils were positive to the assistive technology (the applications on the iPads), they found the apps easy to learn how to use and they appreciated the benefits they could give. Even so, only a few of the pupils had found use for and continued to use the tools after the intervention period finished. Possible reasons are that when the novelty wore off, students reverted to their usual study habits and that older students with many teachers and different classrooms were less able to adapt to using the apps. To improve transfer, it is suggested to introduce assistive technology earlier to students, in the younger grades, before study habits have been formed and to inform teachers about the use of AT in the classroom, including what is available and how it can benefit students.  相似文献   

利用AIS数据计算港口间竞争度的方法     

向哲  施朝健  胡勤友  杨春 《上海海事大学学报》2016,37(1):60-64

为能更有效地提供有价值的航运情报, 借鉴网络分析法相关原理，挖掘船舶AIS数据，获取港口之间的竞争度.该法通过船舶数据模型、港口数据模型、船舶抵达港口事件模型、船舶挂靠港记录、港口之间运力、港口网络等建立港口间竞争度模型. 选取2014年4—8月中国沿海船舶AIS数据和17个主要港口数据，利用模型计算出对上海港竞争度排名前三的港口依次是宁波港、张家港港和南通港.  相似文献   

基于消费者低碳偏好的供应链碳减排策略     

熊榕  梁承姬  韩婷婷 《上海海事大学学报》2019,40(4):52-60

针对一个占主导地位的零售商和两个制造商(名牌产品和普通产品制造商)组成的二级供应链,考虑制造商之间的定价顺序和低碳偏好消费者对普通产品的接受度,分别构建普通产品制造商采用或不采用减排技术情景下的收益模型,得出各情景下最优零售价格和收益。研究发现:零售商选择销售哪种产品与顾客对普通产品的接受度有关;普通产品制造商的减排策略主要取决于减排成本。在相同减排策略下,若顾客对普通产品接受度较大,制造商同时定价时产品的最优零售价小于等于不同时定价时产品的最优零售价,而同时定价时制造商的最优收益大于等于不同时定价时的最优收益,因此两个制造商应同时定价以获得更大的收益。  相似文献
