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 notion of post-Chineseness is enlisted to analyze Vietnamese Sinology as a comparative agenda. Post-Chineseness refers to the cultural preparation and the political process of mutual acknowledgement among those who consider one another sharing (some kind of) Chineseness, practically defined according to the context and its trajectories, at each time and each site. Chineseness can thus have various, if not entirely irrelevant, meanings. Vietnamese Sinologists have relied on different kinds of post-Chineseness to make sense of their relationship with the encountered Chinese to select and determine the mode of self-understanding, the purpose and a strategy to reconnect, and the normative criterion to assess and manage the relationship. Chinese Vietnamese are significantly less numerous than Chinese Malaysian, Thai, and Indonesians. However, the history of Vietnam is considerably closer to China than are those of Korea and Japan, in terms of length of merger. The post-Chineseness of Vietnamese scholarship therefore complicates its role-identity vis-à-vis China, intellectually as well as practically.  相似文献

ABSTRACT

We discuss democratizing knowledge production and dissemination in education illustrated in two parts that challenge the current knowledge monopoly. Our discourse includes (a) problematic cultivation of the status quo in the hierarchy of knowledge value in the U.S. as a component of civic illiteracy and (b) the need for more evidence through developing practice-based research evidence as a counter to the fixation with evidence-based practice in education. We point out a cultivated state of complacency with regard to the societal expectations of the roles of educational practitioners in the U.S. and discuss developing a new status of practitioner research for knowledge democracy. A virtual space for mentoring practitioner researchers with a goal to help them produce and disseminate their research was included as an example of knowledge democracy.  相似文献

This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight adults (age: 44 ± 12 years; body mass index [BMI]: 45.2 ± 7.8 kg/m2) completed evaluations of STS power, strength and functional performance. STS power was measured with a wearable inertial sensor, strength was assessed with the isometric mid-thigh pull, and function was measured with the timed up-and-go (TUG), six-minute walk test (6MWT) and 30-s chair STS. Power and strength (normalised to body mass) entered regression models in addition to age, gender, BMI and physical activity (daily step count). Power displayed large univariate associations with TUG (r = 0.50) and 30-s chair STS (r = 0.67), and a moderate association with 6MWT (r = 0.49). Forward stepwise regression revealed that power independently contributed to TUG (β = ?0.40, p = 0.010), 30-s chair STS (β = 0.67, p < 0.001) and 6MWT performance (β = 0.27, p = 0.007). Power also appeared to be a superior determinant of function compared with strength. Power generated via the STS transfer largely underpins the ability to perform functional tasks in adults with severe obesity, although intervention studies are required to investigate a potentially causal relationship.  相似文献

为探究海上浮式生产储油卸油船(floating production storage and offloading,FPSO)爆燃事故加强机制,采用计算流体力学(computational fluid dynamics, CFD)对FPSO爆燃事故进行数值模拟。模拟结果表明,在拥塞度较大的钢架结构区域,火焰速度和爆燃压力急剧增大。为进一步探究复杂钢架结构和管系对爆燃事故的加强机制,搭建半开敞管道甲烷 空气爆燃实验系统。实验结果表明,在爆燃过程中复杂钢架结构和管系能够诱导火焰产生强烈的湍流作用,加快未燃气体的燃烧速度,导致爆燃事故后果加强。结合数值模拟结果与实验结果,为FPSO爆燃事故防治给出建议。  相似文献

随着消费社会的深化发展,现代消费已成为影响城市空间形态演化的重要因素。以此为出发点,以消费文化的视角来考察城市空间,揭示20世纪80年代以来澳门半岛滨水空间形态的演化特征。研究表明:消费时代,城市主要根据经济诉求组织空间的生产,借助资本的熔铸,澳门半岛滨水空间建设呈现出博彩旅游化、高层豪宅化和空间巨构化等特征,并最终实现空间形态的重塑。在此基础上进行批判性反思,如城市消费空间与传统城市意象的协调发展、城市空间的阶级化和滨水空间的公共性等问题。  相似文献

国务院印发《完善促进消费体制机制实施方案(2018-2020年)》文件中指出"积极培育‘冰雪运动’体育消费新业态"。在此背景下,立足于消费空间视角,以冰雪文化成为空间消费品为切入点,针对我国冰雪文化消费不足的问题,提出了冰雪文化消费空间的概念。研究发现,冰雪文化消费空间不仅具有经济、社会、文化的内涵特征,而且其体验化、商业化、休闲化、娱乐化的典型特征与文化艺术化、信息网络化、全球国际化的非消费要素相互共存,在空间消费活动中逐渐构建成宏观、中观、微观层面的空间体系。最终,在空间生产语境中,基于"生产-消费"的逻辑,提出了将冰雪文化消费空间正式纳入"生产-分配-交换-消费"的过程追求再生产的发展路径。  相似文献
