不同练习手段组合对田径跳跃运动员专项力量训练效果的实验研究   总被引：6，自引：1，他引：5  

赵奇  熊西北 《北京体育大学学报》2002,25(1):122-125

选择八种常用手段,将三种双腿跳跃练习进行组合,另把五种单腿跳跃练习进行组合,对两组14名跳跃项目运动员进行8周的训练,获取了5项身体素质和BIODEX等速测力仪及KISTLER三维测力台的各项指标训练前后的测试数据.实验研究发现,不同的力量练习手段对人体作用是不一样的,轻负荷、重负荷、单腿练习、双腿练习对人体肌肉的影响有各自的特异性.因此,在力量训练中,选择正确而有效的手段和适宜的运动负荷与强度,把各种不同手段进行合理组合,才能求得最佳的综合整体效益.  相似文献

Investigating the Role of Problem Severity and Channel Publicness on the Sophistication of Support-Seeking Messages on Social Network Sites: A Replication Study     

Emily M. Buehler  Ashley M. Peterson  Andrew C. High 《Communication Studies》2018,69(3):304-313

Oh and LaRose (2016) contended that problem severity and channel publicness shape support seekers’ goals, time spent composing messages, and the sophistication of those messages. The current study seeks to replicate and extend Oh and LaRose’s study to produce a more accurate understanding of the factors that influence the sophistication of support-seeking messages online. Support seekers’ goals varied according to the severity of a stressor and the publicness of a channel, and the amount of time people spent composing a message influenced its sophistication. We extend the original study by examining associations that were not initially tested. Time spent composing messages mediated the influence of problem severity on the quality of people’s messages, and this effect was moderated by channel publicness.  相似文献

心理三维：涵义、结构及构建意义     

赵兴奎  张大均  刘宗发 《内蒙古师范大学学报(哲学社会科学版)》2007,36(1):34-36

主观世界的心理物质、自我心理和心理社会三个心理区域称为主观世界的三维空间。心理素质的发展实质就是在教育和环境的影响下,自我心理世界内部的和谐变化导致的心理物质和心理社会世界三维心理空间的膨胀。研究心理三维空间目的主要是为了探讨主观世界的运动的量变转化为质变机制,从而更好地研究不同个体的心理素质特征,为心理健康教育和心理素质教育提供理论依据。在辩证唯物主义指导下,结合客观世界的运行规律,研究主观世界运行规律和机制,科学系统地构建心理世界的三维空间理论对于研究个体心理素质的和谐发展,提高个体的心理健康水平,建立具有中国特色的原创心理学理论具有重要的现实意义。  相似文献

Channel One Revisited: Prospective Teachers and the Role of American Higher Education     

A. J. Angulo  Susan K. Green 《Innovative Higher Education》2007,32(2):105-112

This study examined perceptions of college of education students and their experiences with Channel One, a privately-owned news service used in public education. Given that about one-third of middle and high schoolers in the US view the broadcast every school day, the authors surveyed 172 freshmen to discern their views and attitudes toward Channel One programming and commercials and the role colleges and universities might play in relation to this media service. While most studies on Channel One have been conducted from a K-12 point of view, the goal of this study was to reconsider the topic from the perspective of prospective teachers and post-secondary education.
