High-intensity interval and moderate-intensity continuous training elicit similar enjoyment and adherence levels in overweight and obese adults     

Chantal A. Vella  Katrina Taylor  Devin Drummer 《European Journal of Sport Science》2017,17(9):1203-1211

Background: High-intensity interval training (HIIT) has been shown to improve cardiometabolic health during supervised lab-based studies but adherence, enjoyment, and health benefits of HIIT performed independently are yet to be understood. We compared adherence, enjoyment, and cardiometabolic outcomes after 8 weeks of HIIT or moderate-intensity continuous training (MICT), matched for energy expenditure, in overweight and obese young adults. Methods: 17 adults were randomized to HIIT or MICT. After completing 12 sessions of supervised training over 3 weeks, participants were asked to independently perform HIIT or MICT for 30 min, 4 times/week for 5 weeks. Cardiometabolic outcomes included cardiorespiratory fitness (VO₂ peak), lipids, and inflammatory markers. Exercise enjoyment was measured by the validated Physical Activity Enjoyment Scale. Results: Exercise adherence (93.4?±?3.1% vs. 93.1?±?3.7%, respectively) and mean enjoyment across the intervention (100.1?±?4.3 vs. 100.3?±?4.4, respectively) were high, with no differences between HIIT and MICT (p?>?.05). Similarly, enjoyment levels did not change over time in either group (p?>?.05). After training, HIIT exhibited a greater decrease in low-density lipoprotein cholesterol than MICT (?0.66?mmol?L^?1 vs. ?0.03?mmol?L^?1, respectively) and a greater increase in VO₂ peak than MICT (p?<?.05, +2.6?mL?kg?min^?1 vs. +0.4?mL?kg?min^?1, respectively). Interleukin-6 and C-reactive protein increased in HIIT (+0.5?pg?mL^?1 and +?31.4?nmol?L^?1, respectively) and decreased in MICT (?0.6?pg?mL^?1 and ?6.7?nmol?L^?1, respectively, p?<?.05). Conclusions: Our novel findings suggest that HIIT is enjoyable and has high unsupervised adherence rates in overweight and obese adults. However, HIIT may be associated with an increase in inflammation with short-term exercise in this population.  相似文献   

The governmentality of childhood obesity: Coca-Cola,public health and primary schools     

Darren Powell  Michael Gard 《Discourse: Studies in the Cultural Politics of Education》2015,36(6):854-867

In this paper, we examine the emergence of what might seem an unexpected policy outcome – a large multinational corporation, frequently blamed for exacerbating childhood obesity, operating as an officially sanctioned driver of anti-obesity initiatives in primary schools across the globe. We draw on Foucault's notion of governmentality to examine the pedagogical work of two international programmes devised and funded by Coca-Cola. We demonstrate how these programmes work simultaneously as marketing campaigns and as governmental strategies to position children as responsible for their own health, conflate (ill)health with body weight and strategically employ the concept of energy balance. We argue that these programmes not only act to unite the interests of corporations, governments and schools, but also seek to use schools to reshape the very ideas of health and a ‘healthy life’. We conclude by considering two sets of ethical and political issues that come sharply as corporations like Coca-Cola continue to exploit the policy space created by the ‘obesity epidemic’.  相似文献   

中小学肥胖人群的心理压力分析及其调适策略     

胡春香 《科教文汇》2014,(4):191-192

随着我国物质水平的不断提高,肥胖已经成为威胁我国人民健康的重要因素,中小学生也不例外。肥胖除了会给我们的生理健康产生危害之外,还会对我们的心理健康造成影响,如产生抑郁和焦虑的情绪、人际关系方面的问题及较低的自我评价和自尊水平。但是,现有的关于青少年的肥胖问题主要是从生理方面进行研究,对心理方面的研究相对较少,笔者拟从肥胖对青少年造成的心理压力的角度分析,并提出相应的心理调适策略,为中小学心理健康教育提供理论依据。  相似文献   

转变观念的法宝--肥胖幼儿个案分析与指导对策     

王卉 《科教文汇》2014,(9):94-95

随着生活水平的提高,肥胖儿童日益增多。长时间看电视、不良的饮食习惯、不良的行为习惯、遗传因素及不爱运动都是引起肥胖的原因。而大部分肥胖幼儿依赖性强、动手能力弱、自理能力差。因此,我通过对肥胖幼儿个案的研究分析,探究有效的家园指导对策,帮助肥胖幼儿纠正不良习惯。  相似文献   

成年人腰围与血压、血糖及血脂指标的相关性研究     

尹小俭  林延敏  季成叶  郭强  季浏 《中国体育科技》2011,47(5)

目的:了解腰围与血压、血糖及血脂指标间的相关性,界定预测高血压、高血糖及高脂血症等的适宜腰围切点,为腹部肥胖标准的制定提供参考;方法:测取上海E大学的925名成年人的腰围、血压、血糖及血脂等指标,分析探讨腰围与血压、血糖及血脂指标的相互关系;结果:非腹部肥胖组的血压、血糖、血脂状况优于腹部肥胖组,具有统计学意义;通过ROC曲线法得出,男性腹部肥胖筛选点为89～90cm(P72.5～P77.5),女性腹部肥胖筛选点为76～77cm(P65～P75).结论:WHO建议的亚洲人腹部肥胖标准较适合本研究对象;即使对于成年人,年龄仍是影响腰围的一个重要因素,建议将年龄因素考虑到腹部肥胖标准的制定中.  相似文献

全球化和中国背景下的肥胖          下载免费PDF全文

Colin Boreham 《体育科研》2013,34(1):39-40

中国成人肥胖的发展轨迹可能与美国和欧盟的非常相似——肥胖率迅速上升,研究发现,在过去的20年中,中国男性的肥胖率（BMI≥28）增加了近4倍,从3％增加到11％,女性肥胖率（BMI≥28）也已翻倍,从5％增加到10％：男性腹部肥胖（腰围≥90cm）已由8％增加到28％,女性腹部肥胖（腰围≥80cm）也由28％增加到46％,、肥胖会导致医药费的增加、生产力的损失及受教育方面的损失、、文章认为,导致肥胖增加的群体的能量不平衡都根源于饮食和体力活动两个方面,并提出了有效的肥胖干预计划.  相似文献
