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

我国马拉松跑者深度休闲特质的质性研究     

田海波  周文婷  邱亚君  齐震 《沈阳体育学院学报》2020,(1):54-60

在"马拉松热"的背景下,对跑步参与过程中马拉松跑者的深度休闲特质进行探究。采用滚雪球抽样方式,对20名马拉松跑者进行半结构式访谈,通过质性分析软件NVivo 11.0对访谈资料进行分析。研究结果表明马拉松跑者具有深度休闲的6个特质:坚持不懈、生涯性、显著的个人努力、强烈的认同感、独特的文化、持久的收益。本研究进一步丰富了已有研究成果,其中坚持不懈中的"毅力"和"自我管理"两方面体现了马拉松项目的特点。对马拉松跑者来讲,经济回报和团队发展并不是明显的持久收益。本研究结果拓展了对我国"马拉松热"现象的理解,未来应采用定量方法进行深入研究。  相似文献   

A mathematical model for decision-making in the classification of para-footballers with different severity of coordination impairments     

Diego Pastor  María Campayo-Piernas  Jesús Tadeo Pastor 《Journal of sports sciences》2019,37(12):1403-1410

Classification is a defining feature of Para-sport, and sports-specific classification systems determined through multidisciplinary scientific research are required, i.e., evidence-based and focused on the relationship between the impairment and the key performance determinants. Data envelopment analysis (DEA) was applied as a classification tool using a directional distance function (DDF) model. The aim of the study was to test the DEA as a possible classification tool in cerebral palsy football. We analyse the performance of 56 international para-footballers with hypertonia, ataxia or athetosis, who completed a 20-test battery with DEA models. Five of the tests are included in the model (change of direction: Illinois agility test; jumping: standing broad jump, four bounds for distance, and triple hop with the non-dominant leg; 10-m sprint/acceleration; and ball dribbling, both in a straight line and following a trajectory), showing that players with less impairment exhibit the highest efficiency. This outcome suggests that DEA models might be feasible for detecting and discriminating the performance and magnitude of impairment in cerebral palsy football, with an objective ranking of the athletes in relation to different physical performance tests. This study also provides reference scores for decision-making during classification and guidance for further research in team Paralympic sports.  相似文献   

Sex differences in elbow and wrist joint loading during the cartwheel and round off with different hand positions performed by young gymnasts     

Roman Farana  Gerda Strutzenberger  Timothy Exell  Jiri Skypala  Huw Wiltshire  Gareth Irwin 《Journal of sports sciences》2019,37(13):1449-1456

The aim of the study was to determine if sex differences exist in the key elbow and wrist joint injury risk factors during different cartwheel (CW) and round-off (RO) techniques performed by young male and female artistic gymnasts. Sixteen active young gymnasts (8 males and 8 females) performed 30 successful trials of CW and RO with three different hand positions (parallel (10), T-shape (10) and reverse (10)). Synchronised kinematic and kinetic data were collected for each trial. Two-way repeated measures ANOVA (3 × 2, technique × sex) and effect-sizes (ES) were used for statistical analysis. In conclusion, female gymnasts exhibited greater normalised peak vertical ground reaction forces (VGRF), elbow and wrist compression forces and elbow internal adduction moments during CW and RO skills compared with male gymnasts. In both sexes, the parallel and reverse techniques increased peak VGRF, elbow and wrist compression forces and the elbow internal adduction moment. Increased elbow flexion resulted in decreased peak VGRF, elbow compression forces and elbow internal adduction moment. Injury risk factors including elbow extension and internal adduction moment with axial compression force suggest that a CW and RO in reverse and parallel techniques can be hazardous especially for young female gymnasts.  相似文献   

赛艇技术诊断人机智能决策支持系统的研制与开发   总被引：2，自引：0，他引：2  

胡一平  孙传宁 《山东体育科技》2003,25(2):20-22

针对目前赛艇技术诊断专家系统(RTDS)中存在的过分强调计算机的智能和人机功能的不协调问题，指出专家的一部分智能(指与专家经验有关的能力)与认识主体是不可分的，计算机是不能够代替专家的。认为只有人机合理分工，相互协调，才能从根本上提高决策支持系统的智能。研制人机智能决策支持系统的目的，就是为我国赛艇项目的技术训练提供一种切实可行的诊断方法。  相似文献
