四川省田径后备人才可持续发展研究     

陈小伟  黄海平  刘建  张利锋 《四川体育科学》2014,(1):84-87

采用文献资料、专家访谈、数理统计和比较分析等研究方法,对四川省第10届和第11届运动会田径比赛成绩进行分析,对取得较好成绩和名次（前3名）运动员的后继发展进行跟踪调查,发现运动员可持续发展较滞后,除少数优秀的田径后备人才能够选入专业队继续进行训练外,大多数后备人才严重流失。因此,分析四川省田径后备人才培养现状及存在的问题,并提出相应的对策,为四川省田径后备人才的可持续发展提供一定的借鉴。  相似文献   

我国竞技体育“锦标主义”盛行原因的理性思考     

骆毅  关亚军 《哈尔滨体育学院学报》2014,32(6):6-9

近三十年来,我国竞技体育得到了长足的发展,体育竞技场上,我国体育健儿掠金夺银,取得了举世瞩目的成绩。然而,与竞技体育取得成绩相伴随的是"锦标主义"的盛行,这背离了奥林匹克"重在参与""以人为本"的宗旨和精神,值得人们深思。究其原因主要有四个方面:狭隘的小集团、个人主义、庸俗功利主义的蔓延滋长,竞技体育政治化的消极影响,竞技体育过度商业化、职业化的消极影响,以及竞技体育道德教育的偏失和运动员道德修养的边缘化。  相似文献   

Kinematic characteristics of elite men's and women's 20 km race walking and their variation during the race     

Brian Hanley  Athanassios Bissas  Andrew Drake 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(2):110-124

The aim of this study was to analyse the important kinematic variables in elite men's and women's 20 km race walking. Thirty men and 30 women were analysed from video data recorded during the World Race Walking Cup. Video data were also recorded at four points during the European Cup Race Walking and 12 men and 12 women analysed from these data. Two camcorders operating at 50 Hz recorded at each race for 3D analysis. The two main performance determinants of speed were step length and cadence. Men were faster than women because of their greater step lengths but there was no difference in cadence. A reduction in step length was the initial cause of slowing down with later decreases in speed caused by reductions in cadence. Shorter contact times were important in optimising both step length and cadence, and faster athletes tended to have longer flight times than slower athletes. It was less clear which other kinematic variables were critical for successful walking, particularly with regard to joint angles. Different associations were found for some key variables in men and women, suggesting that their techniques may differ due to differences in height and mass.  相似文献

Medico-science and school hygiene: a contribution to a history of the senses in schooling     

Patrice Milewski 《Paedagogica Historica: International Journal of the History of Education》2014,50(3):285-300

This article takes as its inspiration Ian Grosvenor’s conjectural essay presented for the symposium “Historiography of the Future: Looking Back to the Future” held at the International Standing Conference for History of Education (ISCHE) 33 in July 2011 in San Luis Potosi, Mexico. It contributes to a sensory history of schooling by examining how the problematisation of schoolchildren’s eyesight in school hygiene manuals noted by Grosvenor was, to a large extent, made possible by the deeper transformations that occurred in science in the mid-nineteenth century. These included changes in scientific practices and techniques, the invention of new instruments and the emergence of new “scientific selves” that were, in large part, linked to the emergence of objectivity as a scientific ideal. The “objective view” and practices associated with the ideal of objectivity combined with the predominant style of statistical reasoning reinforced the truth claims of senses research by preeminent European scientists. In turn, it made credible and legitimated the findings that resulted when new scientific techniques, methods and instruments associated with the ideal of objectivity were applied to investigations of schoolchildren’s eyesight in the mid-nineteenth century. Medico-scientific investigations that began by first identifying aspects of schooling that caused harm to the sense of sight were later expanded into multiple hygiene(s) and made possible a broader discourse of school hygiene elaborated in the school hygiene manuals that proliferated in the nineteenth and twentieth centuries. The extent to which precepts of school hygiene underscored the reform of pedagogy and the materialities of schooling suggests that the results of these investigations were profound and far-reaching.  相似文献   

项群训练理论视角下多哈田径世锦赛奖牌地理归属特点分析     

何海龙  唐刚 《体育科技文献通报》2021,(1):154-156

根据项群训练理论,对多哈田径世锦赛所产生的奖牌进行分项群分析,重点分析奖牌以洲为界线的地理归属特点。本届世锦赛北美洲在奖牌数量上有绝对优势,欧洲、非洲紧随其后,在快速力量性项群项目中北美洲、欧洲实力相当;速度性项群项目中北美洲实力强劲处于统治地位;耐力性项群项目是非洲夺金夺牌的重点项目,竞走是亚洲的优势项目。认为当今世界田径朝着多极化的趋势发展,呈现出一超、多强、多弱的竞争格局。  相似文献

The effect of track geometry on 200- and 400-m sprint running performance     

Mike D. Quinn 《Journal of sports sciences》2013,31(1):19-25

Abstract

This study looked at how the geometry of the running track affects performances in the 200- and 400 m sprint running events. Although an athletics track must be designed with two parallel straights and two curved bends, the lengths of the straights and bends are not fixed and may vary within an approved set of limits. The bend can be semi-circular or a double-curve consisting of arcs of two different radii. A mathematical model was used to calculate the effect of track geometry on race times for six different track designs; three with semi-circular bends (encompassing the extremes of the permitted designs), and the three permitted double-curve designs. The calculations revealed substantial differences among the track designs. The time difference (in the inside lane) between the fastest and slowest tracks is about 0.1 s in the 200-m race and 0.2 s in the 400-m race. The time differential between the outside and inside lanes for a double-curve track can be up to 0.08 s greater than for a standard track with semi-circular bends.  相似文献   

Individualized sleep education improves subjective and objective sleep indices in elite cricket athletes: A pilot study     

Matthew W. Driller  Michele Lastella 《Journal of sports sciences》2013,31(17):2021-2025

ABSTRACT

The aim of the current study was to evaluate the effect of personalized sleep hygiene education on sleep indices in elite athletes. Nine elite male cricket players performed 3 weeks of baseline sleep monitoring (PRE), followed by group and individualized sleep hygiene education and a further 3 weeks of sleep monitoring (POST). Subjective sleep questionnaires included the Athlete Sleep Behaviour Questionnaire (ASBQ), the Epworth Sleepiness Scale (ESS) and the Pittsburgh Sleep Quality Index (PSQI). Objective sleep indices were monitored via wrist actigraphy. There were significant improvements (p < 0.05) in two of the sleep questionnaires (ESS and PSQI) and in sleep efficiency (+5%), sleep latency (?29 min) and sleep onset variance (?28 min) following the intervention, all associated with large or very large effect sizes (d= 1.38, ?0.85 and ?0.88, respectively). The current study reports that personalized sleep hygiene education using the ASBQ to target maladaptive sleep behaviours may be effective in acutely improving sleep indices in elite male athletes.  相似文献
