Kate Francis  Tom Williamson  Paul Kelly 《Journal of sports sciences》2021,39(1):23-30

ABSTRACT

We compared cardiometabolic demand and post-exercise enjoyment between continuous walking (CW) and time- and intensity-matched interval walking (IW) in insufficiently active adults. Sixteen individuals (13 females and three males, age 25.3 ± 11.1 years) completed one CW and one IW session lasting 30 min in a randomised-counterbalanced design. For CW, participants walked at a mean intensity of 65–70% predicted maximum heart rate (HR_max). For IW, participants alternated between 3 min at 80% HR_max and 2 min at 50% HR_max. Expired gas was measured throughout each protocol. Participants rated post-exercise enjoyment following each protocol. Mean HR and V˙O₂ showed small positive differences in IW vs. CW (2, 95%CL 0, 4 beat.min^?1; d = 0.23, 95%CL 0.06, 0.41 and 1.4, 95%CL 1.2 ml.kg^?1.min^?1, d = 0.36, 95%CL 0.05, 0.65, respectively). There was a medium positive difference in overall kcal expenditure in IW vs. CW (25, 95%CL 7 kcal, d = 0.58, 95%CL 0.33, 0.82). Post-exercise enjoyment was moderately greater following IW vs. CW (9.1, 95%CL 1.4, 16.8 AU, d = 0.62, 95%CL 0.06, 0.90), with 75% of participants reporting IW as more enjoyable. Interval walking elicits meaningfully greater energy expenditure and is more enjoyable than CW in insufficiently active, healthy adults.  相似文献   

How teachers’ individual autonomy may hinder students’ academic progress and attainment: Professionalism in practice     

Christopher Day 《British Educational Research Journal》2020,46(1):247-264

This article reports a 3-year case study of a primary school in England, in which a recently appointed principal attempted to build ‘collegial professional autonomy’ (Nordic Journal of Studies in Educational Policy, 2 , 2015, 20) within a push to improve students’ progress and attainment. The research examined the tensions between staff who embraced the principal's agenda for collegially agreed change, and whose students’ academic progress and performance improved over a 3-year consecutive period when measured in terms of students’ entry-level attainment and socio-economic factors, and staff who asserted their right to ‘individual professional autonomy’ and whose students’ academic progress and attainment declined. The research: (i) challenges claims that reform necessarily results in school cultures of compliancy, de-professionalisation and the technicisation of teaching; (ii) raises issues concerning the pedagogical leadership of principals in a devolved, ‘self-governing’ school system; and (iii) questions teachers’ entitlements to individual professional autonomy where this is associated with students’ continuing academic underperformance.  相似文献

Student success pocket-graphic: a mountain of data transformed     

Karen Briere  Kelly Drifmeyer 《Public Services Quarterly》2020,16(1):48-58

Abstract

How does a small community college library, without marketing experience or budget, advocate for its value to a campus community and its administrators? We did so by creating an engaging, bright, and easy-to-read “pocket-graphic.” In this column, we reflect on the process of shaping a multi-use product out of a mountain of data. Through research in design practices, field observations of popular information tools, and an uncomfortable step into braggadocio, we learned to articulate the successes of our library. Our “pocket-graphic” told our story, yes – but it also provoked surprise, questions (“you really have all that?”) and delight in the lesser known successes (“you really DO all that!”). In the process, we connected our students more deeply to helpful services and resources, faculty to supportive instruction, and positively changed the tone of conversation with all our stakeholders. By turning data points into selling points, we found insights and a focus that moved our own development forward, helping ourselves to define improved priorities for advancing our critical role in student success.  相似文献   

Not quite university people? Academics teaching on foundation studies programmes in New Zealand universities     

Pat Strauss 《高等教育研究与发展》2020,39(5):1013-1025

ABSTRACT

In the current neoliberal environment in higher education, universities are viewed as a valuable source of income. To generate this income, universities need to attract students, and in order to do so, they need to perform well in global ranking tables. These tables are influenced to a large extent by staff research and postgraduate teaching. Foundation studies programmes (FS) do not usually have a great deal to offer in these categories and this places staff teaching on these programmes in a difficult position. This article explores the perceptions of staff teaching on FS programmes in New Zealand universities, drawing on data from semi-structured interviews with 22 lecturers from four universities. Although lip service is paid in higher education circles to the importance of widening access to university education for traditionally marginalised groups, it appears that staff teaching on FS programmes do not, on the whole, receive acknowledgement, support or reward for the work that they do. Despite their marginalised status, these lecturers are committed to helping second chance learners. However, their ability to make a positive impact on these students’ lives is limited by their lowly status in the university sector. This article discusses the insights of FS staff and considers the implications of their positioning in the university sector. It offers some suggestions as to how, in a small way, universities could address the difficulties these academics face in their attempts to widen university access.  相似文献   

中国武术功夫论的身体素养意蕴与价值     

张震 《武汉体育学院学报》2020,54(10):58-64

运用文献资料法和中国哲学诠释学方法，在"技道并进""德艺双馨"的优秀文化传统和"功夫所至即是本体"的哲学范式下，提出：武术功夫是一个三维合一的概念，其既涵摄本体与主体，亦包纳才艺与能力，还囊括了方法与规则。从"功力"角度看，功夫具备本体的性质，指的是类似禅、太极等理念在长时间实践中的现身性表达；从"功用"的角度看，功夫就是一种高级的搏击竞技能力或表演才艺；从"功法"的角度看，功夫表征了方法运用的得当。其蕴藏了：（1）神形共建；（2）在人伦日用中寻求终身技能的发展；（3）身体技艺与情感意志共同成长三层"元实践"哲学意蕴。功夫旨在塑造整体的人、具体的人和自我超越的人，这无疑与身体素养所强调的"身体锻炼与人格培养并举"的整体论哲学在逻辑上相贯通。武术功夫在语义和哲学内涵两个层面上与身体素养有着极强的互释性，属于中国本有的身体素养思想，这就使得功夫修炼具备了提升当代人身体素养和助推当今武术发挥更广义的教育价值之重要意义。  相似文献

时间使用流行病学在身体活动研究领域的应用     

宋俊辰  李红娟  王政淞 《体育科学》2020,(1):79-88

身体活动与健康促进是公共卫生及运动科学领域研究的重点方向之一。个体一日24 h由睡眠、久坐及各种强度的身体活动组成,已有研究多从单一维度探讨这些行为对健康的影响,忽视了身体活动、久坐、睡眠等行为之间的内在联系及对健康结果的综合影响,可能使相应行为与健康效应间的关联产生偏差。时间使用流行病学研究方法的引入克服了这一不足。以“时间分配”作为切入点,综述国际学术界关于身体活动、久坐和睡眠行为对健康影响的研究现状,并系统阐述了等时替代研究方法、活动-平衡模型、时间使用流行病学的发展及其研究框架。基于此,展望了时间使用流行病学相关理论在身体活动研究领域的应用前景:1、开发新式测量工具并完善数据收集和分析方法;2、建立有关时间使用模式的综合评价体系;3、制订我国大众人群的活动-平衡时间分配推荐指南方案。  相似文献   

习惯行为、执行意向与青少年身体活动意向与行为:基于计划行为理论的扩展模型     

王丽娟  郑丹蘅 《上海体育学院学报》2020,(2):22-32

在计划行为理论(TPB)的基础上,引入身体活动习惯行为与执行意向,构建扩展TPB(METPB)模型,检验该模型对9~19岁青少年群体的中高强度身体活动(MVPA)的适用性,探讨该模型对小学、初中及高中阶段青少年MVPA影响的差异。结果显示:假设模型的拟合度可以接受,纳入习惯行为与执行意向后,METPB显著地提高了其对身体活动行为的解释力。态度和感知行为控制对MVPA行为意向有显著性影响,解释了31.4%的行为意向方差;行为意向和习惯行为对MVPA行为有显著性影响,解释了18.7%的行为方差;执行意向加强了行为意向朝实际行为的转换。METPB模型对于不同学习阶段青少年MVPA意向及行为的影响有显著性差异。其中:主观规范对小学生与初中生MVPA意向产生了显著性影响,而对高中生的MVPA意向并无显著性影响;感知行为控制对3个阶段学生的MVPA意向产生的影响随着学习阶段的上升不断增强。建议:在对于青少年身体活动的干预中,政府、家庭、学校应重视培养学生对于身体活动参与的正确态度,提高其参与身体活动的意愿,培养其参与身体活动的行为习惯,且在对青少年身体活动干预时考虑学习阶段的差异。  相似文献
