我在马来西亚看到的羽毛球

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。     

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

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.

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     

冠军制造

一切精彩源于一只小小篮球篮球运动作常精彩！由美国东海岸萌发的篮球运动，经过一个多世纪的洗礼，如今已风靡全球。在竞技体育的大餐中，篮球属于最有品味的极品佳肴。美国人可以不关心总统是姓布什或是姓戈尔，但没有一个真正的美国人可以不关心篮球。的确，一切精彩源于一只小小篮球。在百年前的美国东部，托马斯．伊．维尔胜（Ｔ．Ｅ．Ｗｉｌｓｏｎ）先生在处于工业革命前的小镇——芝加哥，开设了一个以自己名字命名的体育用品公司。为了维持公司的运行，老托马斯开始研制、生产篮球和橄榄球产品，在此之前，篮球的制造水平低下，工艺…     

运动心理技能量表的常规及信度资料

介绍迈哈尼、戈布尔和贝根斯近来发布了关于一个专门用于运动的测验的信息。该测验是用来评估与特殊运动表现有关的心理技能的。他们编写了一个51道测题的问卷(运动心理技能量表PSIS)。该量表证明,优秀运动员、有潜力的运动员和大学生运动员在注意、焦虑控制、自信、心理准备和动机上彼此存在差异。迈哈尼近来发表了该量表的修订版。原量表被
