我在马来西亚看到的羽毛球     

Mr.Backhand 《羽毛球》2020,(2):110-110

这里是马来西亚紫色联盟最著名的俱乐部——八打灵羽毛球娱乐部,日本队首次拿到汤姆斯杯的功臣田児贤一退役后,也加盟到这里,做教练兼球员。我也不知道他吃了什么,居然胖成这样,人很nice,只是他一口马来口音的英语让我有点儿猝不及防。俱乐部楼道墙上挂起来的比赛服见证了俱乐部的发展,如果说都认识,这一定是暴露年龄的行为了。  相似文献   

友谊与团结     

H·G·伽达默尔 《安徽师范大学学报(人文社会科学版)》2002,30(5):497-501

古代的哲学家几乎没有不在其理论、演说或著作中提到"友谊"这个概念.只有了解的人才会知道,大师亚里士多德在他的三本伦理学著作中赋予友谊概念以核心的地位;而康德这位思想上值得吾人敬重的哲人,在其人类学演讲录中,却只给友谊一页的篇幅.尽管如此,他还是说出了值得我们深思的真理:"真正的朋友稀少如黑色的天鹅."  相似文献   

Immediate effects of the use of modified take-off boards on the take-off motion of the long jump during training     

Koyama H  Muraki Y  Ae M 《Sports biomechanics / International Society of Biomechanics in Sports》2006,5(2):139-153

We investigated the immediate effects of the combined use of inclined and raised flat boards on the take-off motion of the long jump. Eight male long jumpers were videotaped with two high-speed video cameras (250 Hz) set perpendicular to the runway. The athletes jumped with three modified take-off boards: upward-inclined boards of two different inclinations (2.5 and 5.0 degrees), and a raised flat board (50 mm high). The jumpers performed pre- and post-jumps using their own techniques before and after use of the boards to test their effects. The post- jump revealed significantly less reduction in the horizontal velocity during the take-off than the pre-jump, and the effectiveness of converting the velocity from horizontal to vertical increased significantly in the post-jump. The post-jump demonstrated significantly less knee flexion of the take-off leg during take-off. The reduced knee flexion and slower extension velocity of the take-off leg in the second phase of the post-jump contributed to increasing the knee extension torque in the second phase and resulted in the increases in vertical ground reaction force and vertical velocity. These results suggest that the combined use of the inclined and raised flat boards induced immediate effective changes in the kinematics and kinetics of the take-off motion and represent appropriate training tools for take-off techniques of the long jump.  相似文献

从文化的视角透视基础教育课程变革《新中国基础教育课程改革的文化检讨》评介     

别必亮 《出版视野》2004,(4):34-34

课程作为人类教育活动的核心构成，自产生之日起，就一直处于不断的发展变革之中。可以说，变革是课程的本质特征。新中国成立半个多世纪以来，由于社会主义政治、经济、文化的日益进步，特别是在我国实行改革开放政策和科教兴国战略，教育逐渐成为带动社会发展的“轴心机构”之后，这种变革更是高潮迭起，出现了从未有过的繁荣，也取得了举世公认的成就。然而，在这繁荣和巨大成就  相似文献

2005年10月的一天,一位中等身材、面色黝黑的中年干部站在梅河口市教育局大门前,他神情凝重地拿出一支烟。此时的他有些犹豫,有些彷徨,因为他深知,一旦走进这个大门,等待他的不是鲜花,不是掌声,而是多年遗留下来的教师对职称评定的抱怨和4000多万元的巨额欠  相似文献   

The distance-time relationship over a century of running Olympic performances: A limit on the critical speed concept     

Dekerle J  Nesi X  Carter H 《Journal of sports sciences》2006,24(11):1213-1221

We analyse the evolution of the slope (critical speed) and the y-intercept (anaerobic distance capacity) of the linear distance-time relationship over a century of Olympic running performances. The distance-time relationship of each Olympic Games (1920-2004) was plotted using the performances in the 800-, 1500- and 5000-m track events. Values for critical speed and anaerobic distance capacity were determined by linear modelling. Mean performances for the 800, 1500 and 5000 m were 104.9 +/- 1.5 s (1.4%), 217.2 +/- 2.8 s (1.3%) and 808.9 +/- 18.4 s (2.3%), respectively. Critical speed improved during the first three-quarters of the twentieth century to reach a plateau in 1984. This is in accordance with the literature (Peronnet & Thibault, 1989) and suggests that "human aerobic endurance" has improved within the century (+13.4%) and tends to stabilize. Anaerobic distance capacity was highly variable over the century (coefficient of variation = 9.4%) and did not show a linear improvement over the years as has previously been suggested (Peronnet & Thibault, 1989). This could be due to an artefact in the application of the two-parameter model to only three Olympic performances. A limitation to the use of this linear mathematical model to fit physiological data may have been demonstrated.  相似文献   

工场教员与三种工场教授法

教授为各种教员之主要业务.工场教员自亦不在例外.惟工场教员如实验室科学教员.尤须负组织及经理之责.盖工场之设备.少则值数百圆.多则达数千数万圆.是其保管维护.均工场教员一身.万一失于捡贴.势必损坏而失其效用.故为工场教员.须谨慎精细.同时工场教师亦为购货主任.凡工场所需之工具.材料等等.均应由工场教员随时调查.供给支配.此亦须特殊之知识与能力者也.于是我人  相似文献
