This study compared markers of muscle damage and inflammation elevated by a matched-intensity interval running session on soft sand and grass surfaces. In a counterbalanced, repeated-measures and crossover design, 10 well-trained female athletes completed 2 interval-based running sessions 1 week apart on either a grass or a sand surface. Exercise heart rate (HR) was fixed at 83–88% of HR maximum. Venous blood samples were collected pre-, post- and 24?h post-exercise, and analysed for myoglobin (Mb) and C-reactive protein (CRP). Perceptual ratings of exertion (RPE) and muscle soreness (DOMS) were recorded immediately post- and 24?h post-exercise. A significant time effect showed that Mb increased from pre- to post-exercise on grass (p?=?.008) but not on sand (p?=?.611). Furthermore, there was a greater relative increase in Mb on grass compared with that on sand (p?=?.026). No differences in CRP were reported between surfaces (p?>?.05). The HR, RPE and DOMS scores were not significantly different between conditions (p > .05). These results suggest that in response to a matched-intensity exercise bout, markers of post-exercise muscle damage may be reduced by running on softer ground surfaces. Such training strategy may be used to minimize musculoskeletal strain while still incurring an equivalent cardiovascular training stimulus.  相似文献   

Can Academic Freedom be Justified? Reflections on the Arguments of Robert Post and Stanley Fish     

Martyn Hammersley 《Higher Education Quarterly》2016,70(2):108-126

It is widely recognised that academic freedom is currently under threat. But there is also considerable dispute about the meaning of the term. In this paper I examine two recent and important accounts of the nature of academic freedom that seek to distinguish it clearly from free speech. Such a distinction is, in my view, essential. The aim of the paper is to clarify and resolve differences between these two accounts, and thereby to develop further the conceptualisation of academic freedom.  相似文献

Supporting students' preparation for the viva: their pre-conceptions and implications for practice     

Martyn Clark 《Teaching in Higher Education》2013,18(1):71-87

In universities theories and concepts are created and used within a disciplinary context, and some understanding of this context is necessary if students fully are to make sense of their studies. Thus, we investigate computer scientists' perspectives on their discipline. Biglan characterises Computer Science as being hard, rather than soft and as being applied, rather than pure. Therefore, Computer Science is associated with the engineering disciplines. Although many computer scientists support this view, others see the discipline as being identified more properly with Mathematics and/or the sciences. We suggest some reasons for the difference of opinion and highlight the implications for what students might learn about the disciplinary context.  相似文献   

Rethinking the Rural Idyll     

Jonathan Wild 《Cultural and Social History》2013,10(1):73-94

ABSTRACT

This article traces the profound social repercussions that resulted from the mass enlistment of British office workers into the armed forces during the First World War. Drawing heavily upon fictionalized autobiographies of the period, my study examines the various stages of the clerk's experience of the conflict and argues that the confidence gained during warfare by surviving office workers fundamentally shaped a more democratic postwar society. This change is evidenced, I argue, in the profile of the fictional clerk that emerges in British literature after 1918.  相似文献   

Does exercise motivation predict engagement in objectively assessed bouts of moderate-intensity exercise? A self-determination theory perspective     

Standage M  Sebire SJ  Loney T 《运动与训练心理学杂志》2008,30(4):337-352

This study examined the utility of motivation as advanced by self-determination theory (Deci & Ryan, 2000) in predicting objectively assessed bouts of moderate intensity exercise behavior. Participants provided data pertaining to their exercise motivation. One week later, participants wore a combined accelerometer and heart rate monitor (Actiheart; Cambridge Neurotechnology Ltd) and 24-hr energy expenditure was estimated for 7 days. After controlling for gender and a combined marker of BMI and waist circumference, results showed autonomous motivation to positively predict moderate-intensity exercise bouts of >or=10 min, or=20 min, and an accumulation needed to meet public health recommendations for moderate intensity activity (i.e., ACSM/AHA guidelines). The present findings add bouts of objectively assessed exercise behavior to the growing body of literature that documents the adaptive consequences of engaging in exercise for autonomous reasons. Implications for practice and future work are discussed.  相似文献

Participatory Action Research as Change Strategy: A Case of Developing Inclusive Teaching and Learning Practices in an Adult Education Centre in Gauteng East District of South Africa     

Ngwenya  Nthabiseng  Makoelle  Tsediso Michael  van der Merwe  Martyn 《Interchange》2021,52(3):393-414

Adult education is one of the platforms of skills development for the mostly disadvantaged people of South Africa who did not get formal education owing to past segregation and apartheid laws. Recently this sector has implemented inclusive education and is in the process of transforming and changing to achieve inclusion. This interpretative-qualitative case study within participatory action research explored the role of participatory action research as a change strategy to develop inclusive teaching practices and enhance adult student learning in an adult education context. Data were collected through semi-structured interviews, participant observations, documentary analysis, focus group interviews and group interpretative meetings in all four phases, i.e. planning, observation, action and reflection. After the group data analysis with co-researchers during group interpretative meetings and the researcher’s analysis using an interpretative-thematic inductive qualitative data analysis framework, the study found that participatory action research is viable as an educational change strategy, as it enhances collaboration among adult education teachers and improves their ability to be reflective and critical in their practice, which is fundamental in the development of inclusive teaching practices.

AN APPROACH TO THE EVALUATION OF TEACHING COMPANY PROGRAMMES     

Colin A. Carnall  Ray Wild 《Assessment & Evaluation in Higher Education》1981,6(3):249-262

In this paper we consider the problems associated with the evaluation of Teaching Company Programmes. These programmes involve Universities and Colleges, together with manufacturing companies, in efforts to improve manufacturing methods and to develop graduates for careers in manufacturing industry. We introduce a framework for the evaluation of these programmes and apply it to one in which the authors have been involved. The paper reports a number of results from the Teaching Company Programme involving Molins Ltd., Brunel University and Henley, the Management College.  相似文献
