刘洪琦  张志芳  顾鸿泉 《中国体育科技》2002,38(5):56-58

重量感是举重运动员在运动过程中的 1种专门化的运动知觉。从训练和比赛实践中积累的大量资料中列举部分实例来说明重量感在训练和比赛中的典型表现形式 ,着重讨论了重量感的定义、形成过程及主要特征。由于目前举重界对重量感形成的机制、原理尚不清楚 ,在一定程度上影响了选材和训练过程 ,对此问题进行深入的研究和开发十分必要  相似文献   

Storybook models and achievement behavior of preschool children     

Annette U. Rickel  Robert B. Fields 《Psychology in the schools》1983,20(1):105-113

The effects of orally presented storybook models on children's cognitive achievement behavior were assessed in two experiments. Experiment I involved 100 preschool-age children who were given one exposure to either a story depicting achievement behaviors by a male/female model, or a control story describing no achievement behavior. Subjects then were asked to perform a related achievement task. No significant modeling effects were found, but a significant relationship existed between the children's recall of the story content and their performance on the subsequent task. Experiment 11 employed 60 preschool-age children who were given repeated exposures (3 to 4) to, and group discussion of, the same achievement stories or non-achievement control story. A significant relationship was observed between type of story and type of solutions to the subsequent achievement task. These findings are discussed in the context of modeling theory, with practical implications.  相似文献   

冠心病人康复训练后有氧工作能力和心肌供氧的变化     

刘洵  张薇  杨晓龙  原晓晶  杨风英  Brodie DA 《体育科学》2007,27(6):35-38

目的：探讨康复训练后冠心病人进行定量负荷运动时有氧工作能力和心肌供氧的变化，以此为康复效果的评估提供依据。方法：25名男性冠心病人参加了12周有氧多样化运动康复训练，训练前、后对他们在递增负荷运动中的生理和临床指标进行了测定。结果：1）反映冠脉血流和心肌耗氧量的指标RPP，康复训练前在跑台的V级负荷时已超过200，康复训练后增加幅度则有显著下降（P〈0．01）；2）康复训练前受试者的血乳酸浓度（BL）在Ⅳ级运动负荷之后出现了突增（达到4．6mmol／L），而康复训练后他们运动中的BL增加平缓，始终保持较低水平；3）康复训练前在V级运动负荷时受试者的ST下降达到-0．9mm水平，这已接近心肌缺血的阈值，训练后心肌供血出现了明显的改善。结论：康复训练前冠心病人运动中反映运动系统缺氧的BL突增领先于心肌缺血阈值的到达；与康复训练前相比，康复训练后冠心病人在进行相同负荷运动时显示出有氧工作能力有所增强，心肌供氧状况有所改善。  相似文献   

Renewed commitments in a time of vigilance: sexuality education in the USA*     

Lorena Garcia  Jessica Fields 《Sex education》2017,17(4):471-481

Over the past 20 years, the USA has seen more than its fair share of controversy with respect to education about sexuality, sex and intimate relationships. Attention has focused on content (abstinence-only vs. comprehensive instruction), delivery (by teachers, parents, health professionals or community educators) and context (within school and beyond). In recognition of this fact, Sex Education invited the development of a virtual special issue comprising a sample of its most impactful papers on these and related topics. The 2016 Presidential election results and recent legislative action in the USA point to the importance of thinking broadly about teaching and learning about sexuality inside and outside of schools and of considering sexuality as it intersects with categories of difference, privilege and penalty, including ability, age, immigration, race, gender and class. This paper, developed as an introduction to the virtual special issue, opens with a discussion of the journal’s contributions to the ongoing discussion of pleasure and desire in sexuality education. From there, we turn to the question of what is possible given the material and ideological conditions of schooling and then to opportunities for teachers and learners outside the conventional classroom. We follow with a discussion of the place of intersectional analyses in sexuality education research, and conclude with some thoughts on sexuality education research at this political moment.  相似文献

歌唱呼吸与情感的联系   总被引：1，自引：0，他引：1  

笪方能 《新疆师范大学学报(哲学社会科学版)》2003,24(2):142-145

自16世纪美声唱法诞生以来，诸多声乐教育家认为：歌唱的动力是呼吸。“谁懂得了呼吸，谁就掌握了歌唱。”由此可见，呼吸在声乐演唱中的重要性。而歌唱发声的技巧是为歌唱的内容服务的，歌唱蕴藏着丰富的情感要素。但如何借助作品本身的情感因素合理地运用具体恰当的呼吸演唱好作品，充分体现作品的情感，使听众产生情感上的共鸣是声乐教学与演唱的目的之一。  相似文献

贵州省旅游引导水库移民安置模式的研究     

林若飞  笪玲 《昆明大学学报》2013,5(3):59-65

水库移民安置是水库顺利建设的基础,也是贵州省的重要民生问题.从安置区移民的长远发展分析,目前“大分散,小集中”的有土安置模式存在着局限性,新的安置思路迫切需要探索和实践.而旅游引导安置的模式有鼓励和吸引投资,促进社区重建;促使移民脱离有土安置的依赖,推动当地建设开发;有利于库区社会稳定与文化发展、重构等诸多优势,应该成为贵州省水库移民安置探索的重要内容.  相似文献
