经连续五天称重法进行的膳食营养调查发现，我省皮划艇运动员（男性）以膳食中实际获得的营养素跟供给量标准比较，总热量与各营养素的摄入量除维生素Ａ不足（仅占标准的７８．１％）外，其余均超标；三大热能营养素的比例不尽合理（蛋白质２０６．９克，脂肪１７１．５克，碳水化物７０２克分别占总热量的１６％、２９．８％和５４．２％），脂肪量偏高，碳水化合物相对不足。建议在食谱中增加主食、减少脂肪，同时补充维生素Ａ，从而保证皮划艇运动员能得到合理的营养。  相似文献   

欧洲早期滑雪运动发展社会动因及对我国的启示     

伊诺  陶永纯  邱招义 《北京体育大学学报》2017,40(9):9-15

摘要：成功申办2022年冬奥会以来，我国冰雪事业迎来重大发展契机，带动3亿人参与冰雪运动成为我国冬季运动发展的重要目标。采用文献资料法、历史分析法等研究方法，回顾欧洲早期滑雪运动发展的社会动因，是将滑雪运动置于整体社会发展环境中，对生产力、生产关系以及社会的需求等要素进行综合分析，其发展规律反映了生产力发展、精英引导、国家意志等因素的共同作用，体现了欧洲滑雪运动从贵族精英、健康观念形成向大众参与理念转变的发展历程。研究欧洲滑雪从少数人引领到大众参与的进程，将为我国滑雪运动大众化普及提供借鉴。分析认为：1）精英阶级对于滑雪运动的热情促成了滑雪俱乐部在欧洲的兴起，在满足休闲娱乐之余，有效地将滑雪运动与公民意识相结合，培养了社会大众对于资产阶级统治的认同感。2）军事滑雪运动的发展是滑雪运动实现精英阶级向大众推广的重要途径。一战前夕，各国滑雪部队建立，扩大了滑雪运动的参与范围，为国家军事滑雪人才奠定了基础。3）一战后，欧洲国家将滑雪运动引入学校课程体系。政府通过设置学校滑雪课程、降低滑雪价格、住宿、成本等方式鼓励青少年参与滑雪运动，打破了经济基础决定滑雪参与的局面，扩大了滑雪运动的参与群体。随着滑雪人数的增多，各国滑雪比赛逐渐增多推动了国际性滑雪组织建立，欧洲早期滑雪运动得以发展壮大。  相似文献   

基于HHD测试的男子羽毛球运动员肩关节旋转特征分析     

王聪  秦学林 《福建体育科技》2017,36(1)

目的:通过观察男子羽毛球运动员肩关节旋转活动度及肌力的特征,为羽毛球运动员肩关节损伤的预防和康复提供参考。方法:以16名专业羽毛球男子运动员为受试对象,同时以9名普通男子为对照,使用手持式测力计(HHD)测定优势侧及非优势侧肩关节的旋内、旋外肌力;同时,测量其旋转被动活动度。结果:(1)男子羽毛球运动员肩关节旋外被动活动度大于旋内被动活动度。(2)男子羽毛球运动员肩关节优势侧旋内、旋外肌力均大于非优势侧,但旋外/旋内比例不存在双侧差异。结论:(1)男子羽毛球运动员肩关节旋转活动度存在双侧差异。(2)男子羽毛球运动员优势侧肩关节旋内、旋外肌力均大于非优势侧。  相似文献   

认知负荷对乒乓球运动员注意空间的影响*     

杨〓义  岳珍珠 《广州体育学院学报》2019,(2):99-101

目的 同时注意空间中多个目标刺激对于乒乓球运动员非常重要。考察认知负荷对青少年乒乓球运动员注意分布的影响。方法：实验中采用计算机行为实验，控制认知负荷（同时注意的目标数量为2、4或6个），并且在不同注意范围（离中央注视点3°、6°和9°视角）的位置上同时呈现刺激，要求被试对刺激的亮度变化做辨别反应。结果：:认知负荷对于乒乓球运动员的注意范围有显著调节。当刺激个数为2时，在3°和6°视角条件下呈现的刺激反应时均显著快于9°视角条件下的刺激。当刺激个数为4时，视角为3°条件下的反应时快于视角为6°和9°时的反应时，而视角为6°时又比视角为9°时的反应时显著要快。当刺激个数为6时，视角为3°时的反应时均快于视角为6°和9°时的反应时。结论：当前研究证明随着认知负荷增加，乒乓球运动员注意焦点范围显著缩小。可以通过测量运动员在高负荷条件下注意焦点的范围来进行运动员的选拔。  相似文献   

Coaches as sport workers: professional agency within the employment context of elite European basketball     

Laura G. Purdy  Geoffery Z. Kohe  Rūtenis Paulauskas 《Sport, Education and Society》2019,24(2):195-207

Increased activity of multiple stakeholders (e.g. agents and owners) have created new challenges for some coaches working in professional sports clubs. The purpose of this project was to draw attention to the normative or accepted practices inherent in sport work, some of the day-to-day realities of some coaches working in this context, and to understand how coaches’ perceptions of other stakeholders come to bear on their individual circumstances, career expectations/objectives and professional agency. Data were generated from semi-structured interviews with seven professional basketball coaches who worked in top-level European clubs. The analysis reveals the coach’s relationships between some owners and agents differed with respect to exercising professional agency, and, coach’s decisions and actions were tied to their professional ideals as well as understandings of what they need to undertake their work effectively and negotiation and/or adjustment strategies. Occasionally coach’s work practices could be viewed as antithetical to employment security, however, the presence of insecurity was at times embraced and used strategically to affect workers’ career decisions. Amid contemporary regional geo-political shifts, this work aids examinations of global sport settings, structures and issues that may contour sporting professionals’ lives.  相似文献   

Cultures of running: characteristics and determinants     

Geoffrey Lassalle  Robin Recours  Jean Griffet 《Sport in Society》2019,22(3):342-360

Based on the studies of Mauss (1935 Mauss, M. 1935. “Les techniques du corps.” Journal de Psychologie 32: 271–293. [Google Scholar]) and Bourdieu (1980 Bourdieu, P. 1980. Le Sens pratique. Paris: Editions de Minuit. [Google Scholar]) on the determination of body techniques by culture and social background, this study seeks to describe the rules, dispositions and habits specific to different forms of athletic running. It is based on a sample of 732 athletes, all of them are the members of French athletics clubs, comprising 220 sprinters, 213 half-distance runners and 299 long-distance runners. Sports practices are different depending on sub-culture affiliation, sociological characteristics and forms of commitment. This being said, simple links between variables should not be transformed into causal connections. Before drawing such conclusions, it is important to identify the nature of the sport studied. This shows that middle-distance and long-distance enthusiasts, traditionally classified in the same family, have less, in common, than those practising sprint and middle distance. These results potentially question the methodological groups and sociological interpretations made by researchers and sports science.  相似文献   

‘Tidy,toned and fit’: locating healthism within elite athlete programmes     

Seth Brown 《Sport, Education and Society》2017,22(7):785-798

Coaches and athletes have been increasingly inundated with power related ‘truths’ about their bodies, health and performance as they construct their subjectivities. Over the last couple of decades in New Zealand, schools have initiated elite athlete programmes (EAPs) for a select few students based primarily on their athletic ability and fitness levels. Drawing on Gore's techniques of power, my study investigated how healthism and the cult of the body discourses were (re)produced, negotiated and resisted by coaches and elite athletes and how body pedagogies defined and shaped bodies in two high school EAPs. My analysis suggested that ‘toned and fit’ bodies signified responsible athletes compared to ‘fat’ bodies and that elite athletes disciplined their bodies to overcome pain to remain productive. In both EAPs, power circulated at the micro-level of pedagogical practice to normalise and monitor the athletes’ diet, body weight and shape, and reinforced tensions between prudentialism and hedonism.  相似文献   

The effect of smartphones and playing video games on decision-making in soccer players: A crossover and randomised study     

Leonardo S. Fortes  Dalton De Lima-Junior  Lenamar Fiorese  José R. A. Nascimento-Júnior  Arnaldo L. Mortatti  Maria E. C. Ferreira 《Journal of sports sciences》2020,38(5):552-558

ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (p < .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.  相似文献   

Between Tradition and Change: Hunting as Metaphor and Symbol in State Socialist Hungary     

György Majtényi 《Cultural and Social History》2016,13(2):231-248

Through the historic metaphor of hunting the essay examines the lifestyle of the dominant elites of Hungary between 1945 and 1990 on the basis of archival documents, private records, and oral history interviews. The analysis emphasizes the fact that there were interactions between the old, prewar aristocracy and the new state socialist elites. The co-incidence of lifestyles can be viewed through the lens of social and cultural change: new elements hit against the old, shaping and dissolving old behavioural patterns. The article analyses hunting in the contexts of social differentiation and social grouping. Using semiotics the author shows how, even during the era of state socialism, power and social distinctions were articulated on the level of lifestyles, and transmitted via the social, semiotic function of behaviours, patterns of taste, and forms of interaction. Thus, hunting evolved into a metaphor over time in Hungary: it was not only an indispensable part of the everyday life of the elite, but also became a symbol for belonging to it.  相似文献
