BackgroundIndividuals with diabetes have greater central arterial stiffness, wave reflections, and hemodynamics, all of which promote the accelerated cardiovascular pathology seen in this population. Acute aerobic exercise has been shown to be an effective strategy for reducing central arterial stiffness, wave reflections, and hemodynamics in healthy individuals; however, the effects of acute aerobic exercise in reducing these outcomes is not well established in people with diabetes. Recently, implementation of high-intensity interval exercise (HIIE) has shown superior improvements in cardiovascular health outcomes when compared to traditional aerobic exercise. Yet, the effect of HIIE on the aforementioned outcomes in people with diabetes is not known. The purpose of this study was to (i) describe the central arterial stiffness, wave reflections, and hemodynamic responses to a bout of HIIE and moderate-intensity continuous exercise (MICE) in adults with diabetes; and (ii) compare the effects of HIIE and MICE on the aforementioned outcomes.MethodsA total of 24 adult men and women (aged 29–59 years old) with type 1 (n = 12) and type 2 (n = 12) diabetes participated in a randomized cross-over study. All participants completed the following protocols: (i) HIIE: cycling for 4 × 4 min at 85%–95% of heart rate peak (HRpeak), interspersed with 3 min of active recovery at 60%–70%HRpeak; (ii) MICE: 33 min of continuous cycling at 60%–70%HRpeak; and (iii) control (CON): lying quietly in a supine position for 30 min.ResultsA significant group × time effect was found for changes in central systolic blood pressure (F = 3.20, p = 0.01) with a transient reduction for the HIIE group but not for the MICE or CON groups. There was a significant group × time effect for changes in augmentation index at a heart rate of 75 beats/min (F = 2.32, p = 0.04) with a decrease following for HIIE and MICE but not for CON. For all other measures of central arterial stiffness and hemodynamics, no significant changes were observed (p > 0.05).ConclusionA bout of HIIE appears to lead to a greater transient reduction in central systolic blood pressure than the reduction observed following MICE; however, both HIIE and MICE improved augmentation index at a heart rate of 75 beats/min in people with diabetes. There was no significant difference in response to HIIE and MICE in all outcomes. This provides preliminary evidence on the role of HIIE on such outcomes in people with diabetes. 相似文献

The Obama administration campaigned on the platform of increased transparency and access to government information after the limitations of the Bush years. As part of this focus on transparency, the Obama administration is emphasizing the use of e-government and new social media services to open up access to government. This paper explores the considerations and challenges of this approach, such as the inclusion of members of the public with limited access to the internet, the use of non-governmental channels to disseminate government information, the permanence of digital-born government information, and the design of e-government. 相似文献

In the context of the fast changing university, how are academics to grow the capacity to cope with continual change and what can academic/faculty developers do to assist them? The paper first establishes the context of higher education as a challenging environment. It then reviews ideas about scholarship and explores the application of these ideas to university study of students and academics. It examines the role of the scholarship of teaching and learning in developing the capacity for critical reflection and then applies these ideas to academic practice more generally. Finally, the implications for academic development are addressed. Dans un contexte de mutation rapide de l’université, comment les universitaires parviennent‐ils à développer la capacité à faire face au changement continuel et que peuvent faire les conseillers pédagogiques pour les aider? Cet article décrit d’abord le contexte de l’enseignement supérieur comme un environnement rempli de défis. Il examine ensuite des idées liées à l’érudition (scholarship) et explore l’application de ces idées à l’étude universitaire des étudiants et des universitaires. L’article examine le rôle joué par le scholarship of teaching and learning dans le développement de la capacité de réflexion critique et applique ensuite ces idées à la pratique académique de façon plus générale. Finalement, les implications pour le développement pédagogique sont présentées. 相似文献

Education policy in Australia has accelerated its aim to increase participation of under-represented groups in tertiary education including students who are culturally and linguistically diverse and have low socio-economic status. These students generally have not had prior access to privileged academic discourse, which can further disadvantage them in their participation and progress in tertiary education. In this article, we outline a cross-discipline curriculum initiative and pedagogy that draws on critical literacy and the metaphor of discourse community to integrate language and academic skills into community services qualifications. We argue that this – supports the genuine participation of under-represented (non-traditional) students. It aspires to not only support students’ entry into the new academic terrain, but to enable students to adopt a critical stance to the discourses in which they are learning to participate. This we argue is crucial, when expertise is not just a way of meeting its ostensible purposes, but is also a way of exercising power. Although we report on the application of this initiative to entry level curricula (Diploma), we suggest that it has relevance and application to Bachelor levels in a range of disciplines, both in supporting pedagogy and for transition to Bachelor level study. 相似文献
