我国竞技体育后备人才培养现状分析

采用献资料、问卷调查、统计等方法，分析我国竞技体育后备人才培养的现状。学校体育得不到重视，造成高水平人才断层，训练成材率低。其原因是观念和机制、管理造成的。     

三种强度长期训练对大鼠心肌肌球蛋白ATP酶活性和线粒体计量学的影响

建立三种强度长期训练模型。通过对线粒体体视学指标和心肌肌球蛋白ATP酶海性的测定，研究不同训练负荷下长期训练对心肌收缩性能的影响。结果表明不同强度长期训练对心肌肌球蛋白ATP酶海性和线粒体的影响不同。长期耐力训练后心肌肌球蛋白和ATP酶海性和线粒体的适应性反应不一致。可能具有不同的生理学意义。长期高强度间歇训练后心肌肌球蛋白ATP酶活性和线粒体的适应性反应相似。可能具有相同的生理学意义。

对奥运会及我国大型运动会发行体育彩票融资的研究

当代大型运动会明显表现出对资金的高需求,但是目前各国中央政府的财政收入不足是各国政府共同面临的普遍问题,这将严重影响政府对大型运动会的投入,而发行体育彩票正是解决这一问题的主要手段之一.笔者就奥运会发行体育彩票的情况和我国举办大型运动会发行体育彩票的情况及存在问题作一论述,并对我国大型运动会通过发行体育彩票的融资提出建议.     

Impact of end-user search training on pharmacy students: a four-year follow-up study.

The Alfred Taubman Medical Library at the University of Michigan has offered instruction in online literature searching to third-year pharmacy students as a component of the course "Drug Information and Scientific Literature Evaluation" since 1983. In the spring of 1989, a follow-up study was conducted to assess the impact of instruction on four classes of graduates. Of a pool of 151 graduates, 90 (60%) responded to a mailed questionnaire on their use of information and computerized literature searching. The respondents were divided into four subgroups: end-user searchers, users of intermediaries, end users who used intermediaries, and those who did not use computerized literature search systems. Seventy-two percent of the respondents used some type of computerized literature searching, and 42% performed their own searches. The four subgroups differed in general computer use, familiarity with MEDLINE search terminology, information use, reasons for using or not using literature searching, and characteristics of searches (i.e., type, time frame, amount, and frequency). Training in end-user search systems appears to have had an impact on the continued use of computerized literature searching several years after the formal educational program.     

增加助跑步数对男子跳远运动员踏跳动作运动学指标的影响

目的:探讨不同助跑步数对男子跳远运动员跳跃距离、踏跳时间、踏跳指数、身体前旋角速度等踏跳动作运动学指标的影响。方法:募集12名男子跳远运动员,采取不同助跑步数 (6—16步) 完成踏跳动作,利用高速摄像机测量助跑与踏跳时身体重心速度,并计算出相应参数。结果:①随着助跑步数的增加,跳跃距离增加,踏跳时间缩短;②长助跑 (12—16步)与短助跑 (6—10步)跳跃距离比与助跑速度比之间未存在显著性相关关系 (p＞0.05),而与踏跳时间比之间存在显著性负相关 (p＜0.05);③相比于短助跑,长助跑踏跳指数显著减小,踏跳时垂直速度相当,水平速度损失量也显著大于短助跑 (p＜0.05);④ 踏跳时间比与踏跳角度变化量之间存在显著性正相关 (p＜ 0.05),而与平均前旋角速度比之间存在显著性负相关 (p＜0.05);⑤长距离助跑过程中水平速度损失量与身体平均前旋角速度间存在显著性负相关 (p＜0.05),下肢蹬伸速度与踏跳指数之间存在显著性正相关 (p＜0.05)。结论:在6—16步范围内,随助跑步数增加,助跑速度增加,但与跳跃距离增加未存在相关关系;在进行长距离助跑时,缩短踏跳时间,减少水平速度损失的同时提高垂直速度,能够有效提高跳跃距离;在踏跳过程中减小身体前旋的角度可以有效缩短踏跳用时,提高下肢蹬伸速度可获得较大垂直速度。     

体育规则法治化的积极效能与路径选择——以CUBA北大VS中国矿大争议事件为切入点

通过对2021年6月5日CUBA北京大学对阵中国矿业大学比赛争议的分析,引出对体育规则法治化问题的思考。认为体育规则作为体育领域的重要社会规范,对规范体育参与者行为、引导体育参与者及公众的道德观念、促进经济发展都发挥着重要作用。体育规则法治化则有利于形成更加完备的体育规则,提升体育规则权威性,并能促进竞技体育和全民健身协同发展。在依法治国的背景下,应通过法治基础上的体育自治指导体育规则设立,要明确体育规则冲突的法治化解决原则,以及通过充实体育法律体系和转变政府职能等方式,来推进体育规则法治化,为我国体育事业发展提供保障。     

Physician information seeking: improving relevance through research

Health sciences libraries have considerable potential as resources for both formal continuing professional education, as well as the informal continuing education that results from the professional's efforts to solve problems in daily practice. While there is a growing interest in making the resources of health sciences libraries more accessible to practitioners on a routine, day-to-day basis, there also needs to be more awareness of how, when, where, and why professionals look for information in the context of practical problems. This paper reviews recent research that identifies the context in which physicians seek information and advice from external sources, the information sources that physicians access, and the factors that influence which particular sources are sought. The results indicate that physicians vary in their information needs, preferences, motivations, and strategies for seeking information. This diversity suggests that health sciences libraries, in their efforts to be more accessible, should consider "market research" to determine the needs, preferences, and use patterns of the library's targeted users. Libraries may also benefit from exploring alternative methods of improving access to their resources.
