ABSTRACT

Interval 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

The use of morphological knowledge in spelling derived forms by learning-disabled and normal students     

Joanne F. Carlisle 《Annals of dyslexia》1987,37(1):90-108

Currently popular systems for classification of spelling words or errors emphasize the learning of phoneme-grapheme correspondences and memorization of irregular words, but do not take into account the morphophonemic nature of the English language. This study is based on the premise that knowledge of the morphological rules of derivational morphology is acquired developmentally and is related to the spelling abilities of both normal and learning-disabled (LD) students. It addresses three issues: 1) how the learning of derivational morphology and the spelling of derived words by LD students compares to that of normal students; 2) whether LD students learn derived forms rulefully; and 3) the extent to which LD and normal students use knowledge of relationships between base and derived forms to spell derived words (e.g. “magic” and “magician”). The results showed that LD ninth graders’ knowledge of derivational morphology was equivalent to that of normal sixth graders, following similar patterns of mastery of orthographic and phonological rules, but that their spelling of derived forms was equivalent to that of the fourth graders. Thus, they know more about derivational morphology than they use in spelling. In addition, they were significantly more apt to spell derived words as whole words, without regard for morphemic structure, than even the fourth graders. Nonetheless, most of the LD spelling errors were phonetically acceptable, suggesting that their misspellings cannot be attributed primarily to poor knowledge of phoneme-grapheme correspondences. I am indebted to Laurel Fais and students in the Language Training program at the Forman School in Litchfield, Connecticut, for their participation in this study. The first phase of this research project was sponsored by NICHD grant HD-01994 to Haskins Laboratories and by a Dissertation Fellowship from the University of Connecticut. The final stages of work on this project were completed while I was at American International College.  相似文献   

Examining the impact of prior academic achievement on moral reasoning development among college students: A growth curve analysis     

Roisin P. Corcoran  Joanne O’Flaherty 《Journal of moral education》2016,45(4):433-448

Moral reasoning is concerned with making decisions regarding the appropriate course of action in particular situations and has been highlighted as a critical factor that may facilitate (or impede) the effectiveness of educational programs in promoting positive outcomes. This study examined the trajectories of moral reasoning as measured by the Defining Issues Test (DIT2) for college students and to what extent there are intra-individual (within student) and inter-individual (between student) changes in moral reasoning during this developmental period. The results suggest that moral reasoning was best represented by a linear increase on the mean level and non-signi?cant variability across students. The relationship between moral reasoning and students’ prior academic attainment was also examined.  相似文献

LEARNING TO BE IN PUBLIC SPACES: IN FROM THE MARGINS WITH DANCERS, SCULPTORS, PAINTERS AND MUSICIANS   总被引：1，自引：0，他引：1  

Morwenna  Griffiths  Judy  Berry  Anne  Holt  John  Naylor  Philippa  Weekes 《British Journal of Educational Studies》2006,54(3):352-371

ABSTRACT:  This article reports research in three Nottingham schools, concerned with (1) 'The school as fertile ground: how the ethos of a school enables everyone in it to benefit from the presence of artists in class'; (2) 'Children on the edge: how the arts reach those children who otherwise exclude themselves from class activities, for any reason' and (3) 'Children's voices and choices: how even very young children can learn to express their wishes, and then have them realised through arts projects'. The research methodology was rooted in two modes of inquiry, philosophical investigation and action research. The article draws on this research to argue that arts-based work in school has helped disadvantaged and/or disaffected children to engage in activities (both arts-based and others), and to be able to lay the groundwork for exercising voice and agency as they did so. If social justice is to flourish there is a need for particular kinds of public spaces and a need to create conditions such that children can learn to participate in those spaces, whether or not they are comfortable with the usual settings for 'rational argument' or 'deliberative democracy'. It is suggested that arts-based education, in some forms, is one good way of creating these conditions.  相似文献   

Pre-service educators and anti-oppressive pedagogy: interrupting and challenging LGBTQ oppression in schools     

Jennifer Mitton-Kukner  Laura-Lee Kearns  Joanne Tompkins 《Asia-Pacific Journal of Teacher Education》2016,44(1):20-34

There are increasing calls for pre-service educators to be responsive and responsible for anti-homophobic education. This research builds on the ongoing efforts to integrate Positive Space training in our two-year Bachelor of Education programme. We found through a series of focus group and individual interviews that pre-service teachers were aware of Lesbian, Gay, Bisexual, Transgendered, and Queering/Questioning (LGBTQ) oppression, witnessed it in schools, employed a range of strategies, but also experienced challenges due to power dynamics in schools, and may not have recognised the power of their interruptions. Our findings suggest that Positive Space training is valuable and necessary and needs to continue to be explicitly embedded in core courses so that all pre-service teachers, regardless of their discipline, develop the skills and attitudes necessary to be advocates for LGBTQ individuals.  相似文献

Primary Considerations for Primary TEFL in China     

Yvonne Griffiths 《通化师范学院学报》2007,(2):25-31

This article will focus on five key areas relating to Primary TEFL in China.Firstly,the real TEFL context in Chinese primary schools will be discussed in terms of its special characteristics.Secondly,the current methodological approach will be examined from both a theoretical perspective,focusing on government(MOE)policy for primary TEFL,and a practical perspective,based on personal observations of classroom practice.The third section of the article will highlight some perceived shortcomings of current practice,while the fourth will outline the actual needs of primary learners in the Chinese educational system.Finally,the question of how teachers can meet these needs will be examined in relation to:methodological integration; integration of skills and sub-skills teaching/learning;and the exploitation of materials and activities to provide learners with three different types of language input and output opportunities(extensive,intensive and analysed:Swan,2006).  相似文献
