新规则视角下男子跆拳道技战术发展趋势——以世界冠军李大勋为例     

何芸  庞俊鹏 《武汉体育学院学报》2019,53(12):82-87

文章采用文献资料法、专家访谈法、视频分析法和数理统计法，对李大勋在重大国际赛事中的交手回合、基本技术、组合技术的应用频数以及成功率等指标进行统计分析。根据2018-2019年度世界跆拳道联盟公布的最新奥运积分显示，李大勋拥有605.94个奥运积分且高于第二名将近300余分，目前世界排名第一，其技战术风格具有一定的代表性。结果显示：李大勋在比赛中习惯采用前腿侧踢与前腿横踢技术进行主动进攻、控制距离、防守破坏、封堵迎击；利用后腿横踢技术进行补充击打；灵活使用中变中、中变高等变线技术突破对手；新规则后近身贴靠时攻防转换技战术变化多样，"推+踢"技术运用巧妙，增加了其得分手段。分析认为，在实施新规则的比赛中李大勋结合判罚尺度与分值的变化，优化了进攻方式，增加了得分手段，提高了时局节奏，同时反映出现阶段跆拳道项目技战术发展趋势。  相似文献   

网球精英运动员赛间训练调控影响因素SEM分析     

汤国进  邹克宁 《武汉体育学院学报》2020,54(9):86-94

为定量解释精英运动员重大比赛期间竞技状态显性和隐性影响因素间相互关系，运用文献资料、层次分析、模糊评价、数理统计等研究方法，基于国家队、省市运动队295名网球教练员、运动员调研数据，提出精英网球运动员重大比赛期间竞技状态影响因素假设命题，再引入SEM概念模型，对假设命题进行验证。结果表明：（1）竞技状态SEM概念模型中，体能训练整合度、技能训练整合度、心智训练整合度、适应度与保障度可作为隐性自变量，且均对竞技状态因变量有正向影响作用，H₁、H₂、H₃、H₄假设命题得到验证；（2）经SEM检验，依影响因素权重，精英网球运动员赛间竞技状态调控依次表现为技能训练整合度、心智训练整合度、体能训练整合度、适应度与保障度；（3）精英网球运动员的参赛表现，虽主要取决于竞技训练因子，但对于适应度与保障度中自然环境、社会环境和规程规则等非训练因子，同样不容忽视。  相似文献   

动态助词“来”的历时发展及其衰落动因考察     

《信阳师范学院学报(哲学社会科学版)》2021,(5):124-130

古代汉语中,"来"的用法异常复杂,仅其助词属性下就又可以细分出六七种不同的用法,但这些用法大多并未能沿用到现代汉语共同语中,这也包括用作动态助词的"来"。从历时发展来看,动态助词"来"产生之后,在唐五代、宋元、明清三个阶段的使用并未呈现出持续上升的态势,而是在共同语中逐渐衰落了,今天仅在偏南方的一些方言中还有所使用。作为动态助词,"来"的衰落动因是多方面的,既有"来"自身功能负担过重,以及在使用中受限制过多的内因作用,也有系统内部成员竞争的外因作用。  相似文献   

武术与民族传统体育学科建设目标、困境及出路   总被引：1，自引：0，他引：1  

麻江利 《广州体育学院学报》2020,(1):67-70

武术与民族传统体育学作为一门学科尚显稚嫩,其突出表现是学科知识缺乏独立性。综合运用文献资料、归纳演绎、比较分析等研究方法,沿着目标→困境→出路的逻辑线路,对武术与民族传统体育学学科建设问题展开深入探讨。主要观点:1)特色鲜明乃武术与民族传统体育学学科建设的目标,该目标达成所倚赖之原动力是实践内容的相对独立;2)边界模糊是阻碍武术与民族传统体育学学科建设保持特色鲜明、走向成熟的重要理论致因;3)反求诸己是武术与民族传统体育学学科建设打破边界模糊困境、实现特色鲜明目标的出路。如此,武术与民族传统体育学方能因获得独立性而有成长壮大之可能,才有希望摆脱学科依附阴影,乃至问鼎显学的地位。  相似文献   

国家治理现代化视域下我国体育智库的责任与担当     

杨涛 《河北体育学院学报》2020,34(6):50-55

党的十九届四中全会明确提出了“坚持和完善中国特色社会主义制度、推进国家治理体系和治理能力现代化的重大意义和总体要求”。在新的历史时期，我国体育智库的新使命在于推进体育强国、健康中国和体育治理现代化建设。基于此，采用文献资料法和逻辑分析法，从外部和内部两个角度，对我国体育智库的责任和担当进行深入探讨。认为体育智库对内要注重更新管理体制，完善运行机制，建设和优化人才培养体系；对外要通过科研成果转化实现体育产业高质量发展，重塑体育治理生态，提升国家体育文化软实力和国际体育地位硬实力，促进体育融合发展，最终服务于我国体育治理体系和治理能力现代化。  相似文献   

The role of task and ego-oriented climate in explaining students’ bright and dark motivational experiences in Physical Education     

Luis García-González  Javier Sevil-Serrano  Angel Abós  Nathalie Aelterman  Leen Haerens 《Physical Education & Sport Pedagogy》2019,24(4):344-358

Background: A distinction is made in Achievement Goal Theory (AGT) between task-oriented (i.e. effort, intra-individual progress, and self-comparison) and ego-oriented (i.e. inter-individual progress and normative comparison) climates. Combining insights from AGT and Self-Determination Theory (SDT), studies in the PE context have shown that a task-oriented climate positively relates to need satisfaction, although the findings regarding the motivating role of an ego-oriented climate are inconsistent. Moreover, little is known about the role of task- or ego-oriented climates in explaining experiences of basic psychological need frustration.

Purpose: Grounded in AGT and SDT, the aim of the present study was to examine if experiences of basic psychological need satisfaction and need frustration can explain why task- and ego-oriented climates elicit positive and negative motivational outcomes in PE, respectively.

Research design: Cross-sectional study.

Method: A sample of 524 secondary school students (51.1% boys, M_age?=?14.51; SD?=?1.81) from five different secondary schools participated in this study. Students reported on their perceptions of task- and ego-oriented climates, motivational regulations, basic psychological need satisfaction, and need frustration, as well as positive and negative outcomes in PE. Structural equation modeling was used to investigate our objective.

Results: We found that a task-oriented climate had a strong and positive relationship with basic psychological need satisfaction, eliciting a bright pathway to autonomous motivation and affective attitude. An ego-oriented climate was positively related to basic psychological need frustration, eliciting a dark pathway to amotivation and boredom. A negative cross-path from task-oriented climate to basic psychological need frustration was also found, while no significant cross-paths were found from ego-oriented climate to basic psychological need satisfaction.

Conclusions: This study provides a better understanding of the mechanisms that explain why task- and ego-oriented climates shape students’ motivational experiences in PE lessons. It is suggested that a task-oriented climate elicits a bright pathway towards more optimal functioning, because it fosters experiences of need satisfaction and buffers against experiences of need frustration. In contrast, an ego-oriented climate is primarily positively related to feelings of need frustration and negative motivational outcomes. Practical implications for PE teacher training are discussed.  相似文献   

美国体育小镇的运行机制及其对中国的启示     

王峰  郑国华  陈宁 《武汉体育学院学报》2019,53(4):26-33

体育是美国人生活中不可或缺的一部分，发达的体育文化为美国小镇体育的繁荣奠定了基础。研究以美国体育小镇为对象，运用文献资料、实地考察、逻辑分析及ArcGIS地理信息绘图等方法和技术对美国体育小镇进行了研究。结果表明：美国体育小镇的布局属非均匀化发展，存在东强西弱，南强北弱的特点且表现出"马太效应"。进而从社会学的角度分析了美国体育小镇运行的外部环境和内在动力机制，并以典型案例对体育小镇运行特点进行了剖析。建议我国体育小镇的建设应从目标引领、政策驱动、环境支持、形成正反馈循环和塑造灵魂等方面思考以推动体育小镇的建设。  相似文献

Performative technologies and teacher subjectivities: A conceptual framework     

Hans Englund  Jonas Gerdin 《British Educational Research Journal》2019,45(3):502-517

Critical educational literature suggests that an increased reliance upon performative technologies is currently transforming the very foundations from which teacher subjectivities are constructed. Arguably though, the number of studies pointing to this risk or tendency is considerably larger than the ones theorising why this should be the case. Further, in those cases where the relationship between performative technologies and teacher subjectivities is theorised, the psychological mechanisms that the technologies appeal to are seldom brought to the fore. Based on this, the purpose of this article is to theorise the psychological mechanisms that performative technologies appeal to and work through, by means of identifying, systematising and elaborating extant understandings of such mechanisms in the critical educational literature. The results are presented in the form of a conceptual framework (referred to as the CMIS-framework) which suggests that one and the same performative technology may play many different roles, where each such role appeals to and works through a particular psychological mechanism. Importantly, depending on the type of psychological mechanism that is appealed to, the CMIS-framework suggests that this will lead to teachers (un)consciously conducting particular forms of subjectivising work upon themselves, here referred to as compliance, mirroring, identification and self-realisation (CMIS).  相似文献   

锻炼与针刺组合对退行性膝关节炎微循环血流灌注量的影响     

李雪莹  程志新 《武汉体育学院学报》2019,53(1):98-100

目的：锻炼与针刺组合对退行性膝关节炎微循环血流灌注量的影响。方法：研究对象40例随机分为2组，分别是针刺组（单纯针刺）和锻炼组（站桩与针刺组合），对其实验前后疼痛程度（VAS）、微循环血流灌注量（MBPU）及皮肤温度的变化进行检测分析。结果：两组实验后，VAS评分明显降低（P<0.01），锻炼组优于针刺组（P<0.05）；MBPU降低（P<0.01），锻炼组优于针刺组（P<0.05）；局部温度明显提高（P<0.05）。结论：锻炼与针刺组合可以明显缓解退行性膝关节炎的疼痛症状，降低局部微循环血流灌注量，提高皮肤温度；优于单纯针刺疗法。  相似文献
