ABSTRACTInterval exercise training is increasingly recommended to improve health and fitness; however, it is not known if cardiovascular risk is different from continuous exercise protocols. This systematic review with meta-analyses assessed the effect of a single bout of interval exercise on cardiovascular responses that indicate risk of cardiac fibrillation and infarction compared to continuous exercise. Electronic databases Medline, CINAHL, Embase, Scopus and Cochrane were searched. Key inclusion criteria were: (1) intervals of the same intensity and duration followed by a recovery period and (2) reporting at least one of blood pressure, heart rate variability, arterial stiffness or function. Cochrane Risk of Bias tool and GRADE approach were used. Meta-analyses found that systolic blood pressure responses to interval exercise did not differ from responses to continuous exercise immediately (MD 8 mmHg [95% CI ?32, 47], p = 0.71) or at 60 min following exercise (MD 0 mmHg [95% CI ?2, 1], p = 0.79). However, reductions in diastolic blood pressure and flow-mediated dilation with interval exercise were observed 10–15 min post-exercise. The available evidence indicates that interval exercise does not convey higher cardiovascular risk than continuous exercise. Further investigation is required to establish the safety of interval exercise for clinical populations. 相似文献

A content analysis of children’s television examined the frequency with which behaviors were (a) driven by altruistic versus egoistic motivations, (b) performed by affable/surly characters, (c) rewarded/punished, and (d) present in content popular among different age groups (2–5, 6–11, and 12–17 years old). We found that portrayal patterns stressed the importance of egoistic motivations (particularly competence, autonomy, and relatedness) for older children. The findings are interpreted in line with logic underlying the model of intuitive morality and exemplars (MIME; Tamborini, 2013), suggesting that media representations can influence the motivations of their viewers. 相似文献

AbstractThis article details the experiences of four teacher education faculty members as we navigated the consequential implementation of a state-mandated high stakes teacher performance assessment in our educator preparation program. By shifting our perspective from simply complying with an assessment mandate to considering how we can leverage implementation of high stakes performance assessment as a vehicle for program inquiry, we were able to gain significant insight into our practice. 相似文献

Current learning and teaching methods, such as resource–based learning, require children to make use of a range of resources within and outside school. However, access to learning resources, especially ICT (information and communications technology), depends on the facilities available within a child's school, home and local community. A research project entitled "Children, Access and Learning: Resource–based Learning and the Impacts of Environment and Learning Cultures" was undertaken by CIRT (Centre for Information Research) at the University of Central England in Birmingham, UK between March 2000 and September 2001. This research emerged from concerns that circumstances in and beyond school may disadvantage those children without easy access to resources. This article outlines some of the findings of the research in the context of current debates surrounding the growing importance of ICT in education. 相似文献

ABSTRACTMuch of the research on how social media is embedded into the educational practices of higher education students has a Western orientation. In concentrating on a case study of the varied ways in which African International Distance Education (IDE) students actively use social media to shape their learning experiences, we discuss an under-researched group. The paper draws on analysis of 1295 online questionnaires and 165 in-depth interviews with IDE students at UNISA, South Africa, one of the largest providers of IDE globally. WhatsApp emerges as ‘the’ key social media tool that opens up opportunities for IDE students to transfer, translate and transform their educational journey when studying ‘at a distance’. Although WhatsApp does provide a ‘space of opportunity’ for some students, this is framed through socio-technical marginalisation, itself a reflection of demographic legacies of inequality. Exploring social media practices though the case of African IDE students places these students centre stage and adds to the awareness of the multiple centres from which international education is practiced. 相似文献
