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   

'She just got me’: supporting care experienced young people negotiating relationships and identities at school     

Gale Macleod  Robin Dallas-Childs  Colin Brough  Martin Toye 《Journal of Research in Special Educational Needs》2021,21(Z1):25-35

In this article we examine the complex relationship between care experience, mental health and exclusion from school and how young people (YP) negotiate these different experiences and identities. The study is a secondary analysis, informed by symbolic interactionist theory, of interviews conducted with 19 care experienced YP in Scotland. Not all of the YP were excluded and not all had a formal mental health diagnosis, as such our study design allows interrogation of the contexts and relationships which not only facilitate but also disrupt pathways to exclusion. It also allows reconsideration of assumptions of vulnerability which are often applied to care experienced YP. Our findings suggest that these YP are moving beyond ‘role playing’ the identities ascribed to them and actively seek out relationships which enable them to construct alternative identities.  相似文献

公共健康视角下的电子竞技发展趋势研究     

闫金 《山东体育科技》2020,(1):11-15

电子竞技(E-sports)已经成为当代发展最快,且最重要的文化现象之一。国家体育总局于2003年将它列为第99个运动项目,又在2011年再次将电子竞技改为正式比赛项目。电子竞技从运动员、观众和经济价值而言,是一个不断发展的产业,而且它将被列入2024年巴黎奥运会。虽然最初主要是年轻男性对电子竞技感兴趣,但电子竞技有可能在更广泛的用户群体中带来健康行为的改变。本文运用文献资料法,对比分析法和逻辑分析法探讨电子竞技在整个生命周期内影响健康行为以及一些主要困境的解决措施。除此之外,电子竞技将有可能帮助于个人改变其体育活动和健康行为。最后考虑到电子竞技的指数增长,对于学者和政策制定者来说,认识到电子竞技带来的机遇是非常重要的。  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

Acute cardiovascular responses to interval exercise: A systematic review and meta-analysis     

Kym Joanne Price  Brett Ashley Gordon  Stephen Richard Bird  Amanda Clare Benson 《Journal of sports sciences》2020,38(9):970-984

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 benefits of ethnic activity group participation on older immigrant well-being and host country adjustment     

《Int J Intercult Relat》2020

Drawing on acculturation and social identity literatures, the present research extends on initial work on social group connectedness among older immigrants to examine in a quasi-experimental study the well-being benefits of participating in heritage culture groups. Older immigrant clients (N = 66) of six aged-care agencies in Australia were given diary booklets in which to complete a set of measures on selected days when they did or did not attend the agencies’ heritage culture group activities, over a 2-month period. Results showed that heritage group participation reduced loneliness and increased well-being. Future research should replicate and extend these findings to assist our understanding of how heritage culture group participation aids first-generation older immigrants with aging successfully in a foreign land.  相似文献   

适应性完美主义、自主动机对青少年锻炼坚持性的影响:父母自主支持的调节效应     

董宝林  毛丽娟 《上海体育学院学报》2020,(2):11-21

目的考察适应性完美主义、自主动机对青少年锻炼坚持性的综合影响,检验父母自主支持的调节效应。方法修订父母社会背景调查问卷(家长报告)的自主支持分量表、中文Frost多维度完美主义问卷的个人标准和条理性分量表、因果控制点知觉量表和青少年户外运动坚持性量表,对2230名12~18岁青少年及其家长进行调查,分析适应性完美主义对青少年锻炼坚持性的间接影响。结果父母自主支持、青少年的适应性完美主义和自主动机对锻炼坚持性正向影响皆显著,分别解释了3.7%、30.3%和38.3%的变异;在适应性完美主义与青少年锻炼坚持性的影响链条上,自主动机的中介效应、父母自主支持的中介调节效应、性别的调节中介效应皆显著,三者共同的间接效应值为0.426,占总效应的77.45%。结论适应性完美主义既能直接影响青少年的锻炼坚持性,又能通过自主动机的中介而间接作用于锻炼坚持性;父母对青少年体育锻炼的自主支持能够对青少年的适应性完美主义和锻炼自主动机产生积极的调节作用;相较于女性青少年,男性青少年的锻炼自主动机更强烈、锻炼亦更具坚持性。  相似文献
