伦敦奥运会男子20km竞走运动员的战术节奏分析     

高玉花 《广州体育学院学报》2013,33(3):65-69

通过对伦敦奥运会男子20km竞走运动员的战术节奏分析,对运动成绩的影响采用观看录像、文献资料调研、比较分析法、逻辑分析法及数理统计等研究方法,对参加伦敦奥运会男子20km竞走的个人最好成绩在1∶20∶00之内,或本次比赛前8名的共计17名运动员的战术节奏系统分析发现:17名运动员表现出的战术节奏与专项需要的匀速节奏不完全一致;前8名运动员全程速度节奏都以变换节奏为主,但他们途中变换节奏的距离、方式和速度存在差异性,运动员最后速度大幅度下滑的距离也不同;17名运动员的位置节奏表现为交替型.所以说变换节奏对竞走运动员的运动成绩有重要影响,而中国竞走队更依赖于团队协作.  相似文献

步行锻炼对更年期焦虑症患者生活质量的影响   总被引：1，自引：0，他引：1  

黄红梅  陈锦红 《体育科学研究》2010,14(4):95-98

为了进一步观察步行锻炼对更年期焦虑症患者焦虑水平的影响和步行锻炼对更年期焦虑症患者生活质量的影响。对41例更年期焦虑症患者每天进行30 min以上的匀速步行锻炼,持续2个月,同时给予药物治疗。40例对照组仅进行药物治疗。于开始步行锻炼和药物治疗前以及治疗结束后1周内,分别采用汉密尔顿焦虑量表（HAMA）对两组患者进行焦虑水平评定分析,采用健康调查简易量表（SF-36）评定其生活质量。结果表明：两组HAMA评分均下降,但步行锻炼组下降程度较对照组更显著（P〈0.01）。治疗后两组患者SF-36各维度评分均较治疗前明显提高;治疗后步行锻炼组SF-36大部分项目评分明显高于对照组（P〈0.05）,其中MH的差异具有非常显著性意义（P〈0.01）,但BP的差异无显著性（P〉0.05）。结论：短期步行锻炼能显著改善更年期焦虑症患者的焦虑水平,提高患者的生活质量。  相似文献   

神思：寂寞而自在地行走——论许辉的中短篇小说     

方维保．  胡妍 《海南师范大学学报(社会科学版)》2013,(11):27-31,43

许辉的创作经历了整个新时期小说的发展历程。“行走”是其小说的基本叙述模式。特殊的人称修辞昭示了其文化身份的双重性,以及创作主体自我的倾向性选择。直观化的呈现方式,则造就了其简单微涩的风格,也传达了他道法自然的生命哲学。寂寞而超脱的“我”化感受,传达的是一种神思和空灵。许辉的小说与新时期众多的小说思潮中的创作具有相似性,但它从来就行走在思潮的边缘。  相似文献

Learning with the Natural Environment: How Walking with Nature Can Actively Shape Creativity and Contribute to Holistic Learning     

Maarit Mäkelä  Bilge Merve Aktaş 《The International Journal of Art & Design Education》2023,42(1):139-154

Learning takes place in various spaces through human and nonhuman interactions. Considering the urgent need for rethinking how humans relate to nature, in this article we present a MA level course in the context of art, craft and design to discuss how learning with the natural environment approach can impact learning experiences. We introduce walking with nature as a creative method that fosters students’ ability to let the environment actively shape their creative events. The encounter with nature-based materials in their different forms and following the material's flow provides students with a foundation for their creative processes. This study proposes that walking can facilitate the entanglement between the student's knowledge and encountered materials, generating an emotional and dialogical relationship with the natural environment that contributes to a holistic learning experience. We propose that such an experience can help in comprehending the importance of the caring actions we need to take and maintain towards the nonhuman world.  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   

我国优秀竞走运动员2007-2008奥运备战年度训练特征研究     

胡好  翟波宇 《中国体育科技》2009,45(1)

以2008年北京奥运会竞走比赛第4名王浩、刘虹为例,通过对教练员访谈、相关文献分析、训练计划及训练笔记整理,得出我国优秀男、女竞走运动员大赛备战年度训练安排特征。研究发现:年度不同数量的训练阶段按其内容属性仍遵循一般准备阶段、专门准备阶段、赛前阶段及比赛阶段规律。训练内容、训练量与训练强度规划与不同训练阶段性质、阶段任务、运动员现实状态密切相关,呈现阶段性特点,强度变化主要通过训练环境来调整。在年度训练的不同阶段,训练方法、手段较为稳定,所不同的只是实施时的强度或难度不同。  相似文献
