大学生涉跑猝死事件的体医融合防卫机制研究     

洪邦辉  胡庆山  张恒波  向彪 《武汉体育学院学报》2020,54(2):32-36,58

近年来，大学生身体素质不佳，已成为"老大难"，也是刻不容缓需要解决的问题，多地曾出现在体测、运动会、马拉松中晕倒甚至猝死事件，这给学校体育工作的开展带来不小的考验。带着因涉跑引起猝死的疑问，通过猝死案例分析，探究高校大学生猝死的病理学的非运动成因。研究认为：涉跑猝死的主因是先天性生理疾病，运动不是引发猝死的主要诱因，并提出了预防运动猝死的"堵疏结合"的医学监控策略和体医融合防卫机制构建方法。建议通过入校时医学筛查、跑前医学检查、跑中医学观察、猝死现场急救、跑后跟踪复查降低猝死风险；建立宿舍、运动场地、运动项目的全覆盖的心脏复苏志愿队伍，实施"黄金8分钟"内的急救生存链；建立学生、学校、政府、社会四方体育运动分级分类保险制度，从风险转移和人道主义援助进行关怀；建立涉跑猝死、猝死、非正常死亡的数据库，开展非正常死亡人员的病理学研究；建立全生命周期医学监控和健康安全宣传教育，形成全方位、全过程、全人员的体医融合防卫机制。  相似文献   

Walking and biologic ageing: Evidence based on NHANES telomere data     

Larry A. Tucker 《Journal of sports sciences》2020,38(9):1026-1035

ABSTRACT

The length of telomeres is an objective measure of biologic ageing. This study evaluated the extent minutes of walking per week are associated with leukocyte telomere length (LTL) in a random sample of 5,823 U.S. adults. The investigation was cross-sectional and data were obtained from the National Health and Nutrition Examination Survey (NHANES). LTL was measured by the quantitative polymerase chain reaction method. Walking minutes was calculated from walking frequency and duration measures. Results showed that for each year of chronological age, telomeres were 15.6 base pairs shorter (P < 0.0001). With walking minutes and LTL treated as continuous variables, the relationship was quadratic, not linear (F = 11.2, P = 0.0023). With walking time divided into three categories, adults who performed ≥ 150 minutes of walking per week had longer telomeres than those who did no regular walking, and those who did some, but less than the recommendation (F = 5.0, P = 0.0137). Regular walkers were estimated to have a biologic ageing advantage associated with 6.5–7.6 years less biologic ageing compared to non-walkers, after adjusting for covariates. Additional investigations designed to study causality and the mechanisms associated with the walking and LTL relationship are needed.  相似文献   

我国图书情报领域期刊论文的科学数据引用特征研究     

丁文姚  李健  韩毅 《图书情报工作》2019,63(22):118-128

[目的/意义] 探索期刊论文科学数据引用特征与规律不仅有助于描述学科领域对科学数据的利用情况，还能够揭示学术成果表达中的数据引用模式。[方法/过程] 以我国图书情报领域6种期刊2017年与2018年第一期刊载论文为样本，结合国家标准《信息技术科学数据引用》的引用元素，采用内容分析法从9个维度对样本论文的科学数据引用行为进行数据编码，应用统计学方法描述图书情报领域期刊论文科学数据引用特征并探索不同维度特征间的关联关系。[结果/结论] 图书情报领域期刊论文广泛引用来自国内外的统计整理类科学数据，对期刊论文中个人研究科学数据的引用量较大；科学数据引用标注方式与科学数据类型存在一定对应关系，但多样化的标注方式缺乏统一性；二手引用现象较为突出，二手引用程度与科学数据创建者类型相关。  相似文献   

Facilitators and Barriers to Movement Integration in Elementary Classrooms: A Systematic Review     

Robert Dan Michael  Cate A. Egan  Lynda Nilges  Ali Brian  Robert Johnson 《Research quarterly for exercise and sport》2019,90(2):151-162

Purpose: A systematic review was conducted to identify facilitators and barriers to movement integration (MI) in elementary school classrooms. Method: Online databases (Educational Resources Information Center, Google Scholar, PsycINFO, and PubMed) served as data sources for the study. Following the PRISMA guidelines, relevant published research on MI was identified and screened for inclusion in a qualitative synthesis. Content analysis of the included articles (N = 28) was used to identify themes of MI facilitators and barriers. Facilitators and barriers were then categorized using a social-ecological framework. Results: A total of 12 themes of MI facilitators and barriers were identified and categorized into two social-ecological levels: institutional factors (e.g., administrative support, resources) and intrapersonal factors (e.g., teacher confidence, ease of implementation). Conclusion: This review can inform research and practice aimed at supporting the implementation of MI in elementary classrooms.  相似文献   

从国家社会科学基金项目课题指南论体育学术期刊传播的导向——以2016年国家社会科学基金项目课题指南（体育学）为例     

付志华  简德平  刘静  汤惠琼 《北京体育大学学报》2016,39(12):44-49+81

摘要：国家社会科学基金项目课题指南正越来越深刻地影响着学术期刊编辑的选题策划，进而影响到编辑传播行为的导向。研究试图为编辑传播行为提供科学的理论指导，以体育学术期刊的传播导向为研究对象，采用综合分析法与文献资料法，以2016年国家社会科学基金项目课题指南（体育学）为例，阐述了该课题指南从体育改革与发展、体育与健康促进、全民健身、体育产业、体育法学、公共体育服务、体育传播学等领域对体育学术期刊编辑选题策划的借鉴价值及其传播行为的导向价值。体育学术期刊编辑在传播实践中，应注重参考国家社会科学基金项目课题指南，力求提升选题策划的整体质量，不断提升体育学术期刊的学术影响力与社会美誉度。该研究有助于学者与编者更精准地把握好研究方向与选题方向，进一步繁荣体育人文社会学领域的学术研究。  相似文献   

Learning and adaptation with regard to complementary medicine in a foreign context: Intercultural experiences of medical students from different cultural backgrounds     

《Int J Intercult Relat》2016

Little is known about challenges and transition that medical students from different cultural backgrounds face with regard to complementary medicine (CM). This paper explores such students’ experiences and perspectives of socio-cultural and academic difference with regard to CM and experiences of intercultural relations. Using a constructivist grounded theory approach, 30 in-depth qualitative interviews were conducted with medical students across 10 Australian medical schools. The data were rigorously analysed through a systematic process of coding, categorisation and theoretical development. The findings indicate that students adapted considerably to the host culture. Students with Western backgrounds integrated better socio-culturally and academically compared to students with non-Western backgrounds. Although nationality represented cultural identity, students’ construction of cultural difference was informed by their perception of diverging value systems within the specific educational environment. These values were, in turn, reflected in students’ reported behaviours, attitudes, and levels of engagement in socio-cultural and academic aspects of university life. Adaptation employed by students was evidenced largely due to their conflicting sense of responsibility towards familial culture regarding CM and focus on fitting in. While students’ tendency to gravitate towards cultural peers was evident, most students adapted to their host environment regarding CM to fit into normal intercultural encounters during medical school. In conclusion, students’ intercultural contact with regard to CM was both complex and problematic. At a time of significant diversification within the higher education student body, this paper highlights the role medical education institutions can play in fostering intercultural and academic guidance and support.  相似文献

不同古典医学文化中的“运动是良医”思想     

李文川  刘春梅 《北京体育大学学报》2017,40(8):133-140

摘要：慢性疾病成为新世纪重要的致死风险因素，而身体活动不足成为引发慢性疾病的重要原因。2007年，由ACSM（American College of Sports Medicine）、AMA（American Medical Association）发起“运动是良医”的全球行动至今已有39个国家加入。主要采用文献资料法，梳理古典医学文化时期中“运动是良医”思想的源起。研究发现，早在公元前的古希腊、古代罗马、古代印度以及古代中国古典医学文化时期的医学典籍中就出现了“运动是良医”的思想和实践，Herodicus、Hippocrates、Galen、Susruta、华佗等对这一思想的发展做出了重要的贡献。虽然东西方医学与锻炼的结合具有同源异流、动静相宜等差异，但对于锻炼对疾病的预防和治疗的价值认识是一致的。甚至于早在古典医学文化时期就开始了身体锻炼与肥胖、糖尿病等疾病治疗的实践，并从自然、人体、锻炼、饮食等因素对疾病和健康有了整体的认识。文艺复兴后，由于医学技术的高速发展，“体”“医”开始分道扬镳，今天，体医结合重新受到医学和体育领域的重视，通过文献分析使我们对“运动是良医”这一古老的思想有更加深刻的认识。  相似文献
