目的:通过对湖南师范大学9名北狮运动员双侧膝关节屈伸肌群进行等速测试,为揭示该项运动膝关节肌群收缩的生物力学特性提供实验依据。方法:采用BIODEX SYSTEM 3等速测试系统对湖南师范大学北狮运动员膝关节屈伸肌群进行等速测试,测试指标为峰力矩、相对峰力矩、屈伸肌峰力矩比、平均功率及做功疲劳度。结果:1)北狮运动员双侧膝关节屈伸肌峰力矩和相对峰力矩随测试速度的增加呈递减趋势;2)狮头狮尾屈伸肌群峰力矩比值和做功疲劳度无显著性差异;3)狮头狮尾左右膝关节同一肌群峰力矩无显著性差异。结论:舞狮运动员膝关节肌群峰力矩变化随测试速度的增加而减少,平均功率呈现随运动速度的增加而增加,到达一定速度后随速度的增加而减少的特征。     

Comparing para-rowing set-ups on an ergometer using kinematic movement patterns of able-bodied rowers

While numerous studies have investigated the biomechanics of able-bodied rowing, few studies have been completed with para-rowing set-ups. The purpose of this research was to provide benchmark data for handle kinetics and joint kinematics for able-bodied athletes rowing in para- rowing set-ups on an indoor ergometer. Able-bodied varsity rowers performed maximal trials in three para-rowing set-ups; Legs, Trunk and Arms (LTA), Trunk and Arms (TA) and Arms and Shoulders (AS) rowing. The handle force kinetics of the LTA stroke were comparable to the values for able-bodied literature. Lumbar flexion at the catch, extension at the finish and total range of motion were, however, greater than values in the literature for able-bodied athletes in the LTA set-up. Additionally, rowers in TA and AS set-ups utilised more extreme ranges of motion for lumbar flexion, elbow flexion and shoulder abduction than the LTA set-up. This study provides the first biomechanical values of the para-rowing strokes for researchers, coaches and athletes to use while promoting the safest training programmes possible for para-rowing.     

肘关节屈伸肌群等速肌力的测定与分析

对27名青年大学生志愿者肘关节进行等速向心测试,探讨肘关节屈、伸肌群在不同运动速度下的峰力矩（PT）、峰力矩比（F／E）、疲劳指数（WF）及其变化情况和性别差异,为今后运动医学、临床医学、康复医学的实践提供参考。结果表明：随速度增加,肘关节屈、伸肌群的PT值皆明显下降,F／E值显著提高;男性在不同测试速度下,肘关节屈伸肌群PT值指标均明显高于女性;不同性别的肘关节F／E值,在慢速测试时,不存在显著性差异,但快速测试中,差异却极显著;男女肘关节屈伸肌群的WF值皆存在差异,但差异不显著。     

骨关节活力操练习对青年白领柔韧性影响的研究

目的:探索骨关节活力操对青年白领柔韧性的影响和作用,为大众健身提供理论依据。方法:随机招募60名20-39岁青年白领接受12周,每周3次,每次45分钟的骨关节活力操练习,12周训练前后分别进行关节活动度、转肩握距、俯卧背伸、坐位体前屈等柔韧性指标的测试。结果:1.骨关节活力操练习可以显著增加青年白领肩关节伸展、内收活动度。2.骨关节活力操练习可以显著改善青年白领髋关节伸展、外展活动度。3.骨关节活力操练习可以显著改善青年白领踝关节背屈活动度。4.骨关节活力操练习对青年白领转肩握距、俯卧背伸、坐位体前屈均有良好的促进作用。结论:骨关节活力操融入了日常生活的身体功能训练,可以有效改善青年白领柔韧性,对于保持关节活动度,对抗因增龄和活动减少带来的柔韧性下降,有非常良好的效果,可以降低静坐少动以及不良身体姿势带来的身体隐性损害,是白领全民健身的良好选择。     

羽毛球上网步法和杀球技术造成青少年运动员膝关节损伤的原因分析

经研究调查,总结马来西亚等国外优秀青年羽毛球运动员的损伤发生率为0.9%/1000h,专业训练产生的良好动作定型对预防损伤等方面的影响较大。反观我们国家的青年羽毛球运动员的损伤比竟然高达46%。目的:针对羽毛球运动的特殊性,为了减少运动损伤的发生率,为广大教练员们了解损伤的发生机制和错误技术动作的危害提供参考。方法:从北京体育大学体育竞技学院挑选出羽毛球专项运动员12名。通过定点二维平面拍摄在比赛中用两台高清运动摄像机(数码摄像机(Go Pro—Hero))以60Hz的频率、1/1 000 s的快门速度,进行视频录制。裁取有针对性的视频片段进行分析。结果:得分低于14分的运动员膝关节屈角(°) 100±15°、膝关节外旋角9±5°、膝关节内收角7±6°;得分高于14分的膝关节屈角(°) 125±20°、膝关节外旋角3±2°、膝关节内收角2.5±3°。结论:1) FMS得分低于14分的运动员在做技术动作时,其关节角度已经达到了损伤阈值;2)下肢FMS的得分是与膝关节损伤有紧密关系。3)青少年运动员的FMS得分左右相比均有很大差异。

Co-production of Knowledge in Multi-stakeholder Processes: Analyzing Joint Experimentation as Social Learning

Purpose: Changing research design and methodologies regarding how researchers articulate with end-users of technology is an important consideration in developing sustainable agricultural practices. This paper analyzes a joint experiment as a multi-stakeholder process and contributes to understand how the way of organizing social learning affects stakeholders’ ownership of process outcomes. Design/Methodology/Approach:A learning group composed of the different stakeholders of the oil palm seed system in Benin was set around a joint experiment. We use a detailed account of the group dynamics to understand the social process. Findings: The way the process is designed and conducted has a great effect on the ownership by the participants. Methodological steps taken in this research process showed its efficacy to produce quick and positive feedback mechanisms. Stakeholders’ perspectives on what constitutes a quality oil palm seedling varied widely. Participants, mainly nursery holders, learned new production practices. Representatives of the research center learned a mismatch of recommendations with users’ contexts. Field observations further to the process indicate changes in practices among stakeholders that would be sustainable. Practical Implications: Beyond focusing on outcomes, initiatives in multi-stakeholder processes should also document and analyze social processes in order to better understand the mechanisms by which such processes foster socio-technical change, as well as identify potential institutional barriers to such processes. Originality/Value: Through a detailed analysis of group dynamics, this paper addresses an important knowledge gap in participatory agricultural development.     

学习型社会视角下对高职高专社会助学的思考——以贵州省为例

建设"人人可学、人人要学、人人能学"的学习型社会是社会发展的必然要求。特以贵州省为例,总结已开展的助学实践经验教训的基础上,初步探讨学习型社会中高职高专社会助学的重要意义和新的助学作法。在学习型社会中,推动高职院校社会助学的新发展,需要我们创新助学方法,把培养学习自主性和自觉性作为高职高专助学的最终目标,实施学分银行、学分互认等高职高专助学的新形式,开展网络助学、短期社会培训等助学新方式,建立健全高职院校的助学管理机构和管理办法,实现助学的制度化、规范化。
