AbstractIn 1938, Mormon missionaries from North America, under the leadership of Frederick Salem Williams, formed an athletic club, Club Atlético Los Mormones (‘The Mormons Athletic Club’, CALM), in Buenos Aires, Argentina. CALM would sponsor professional teams in baseball, softball, and basketball, all bearing the name Los Mormones (‘The Mormons’). Los Mormones won three league championships in the four years they played baseball and four championships in the five years they played softball. Two of their basketball players would become national all-stars, one of whom would represent Argentina at the South American Championship in 1940. Williams served as president of the softball league and vice president of the baseball league. Los Mormones’ story is outlined and situated in relation to the various discourses that, woven together, constitute the cultural context of modern Argentine sport: physical culture and modernity, United States-Argentine relations, amateurism versus professionalism, and the spread of North American sports to Latin America. 相似文献

中国棒球运动与亚洲职业棒球发展差距的研究 总被引:1,自引:0,他引:1
苏日光 《哈尔滨体育学院学报》2008,26(4):62-63
棒球在日本、韩国和中国的台湾省有着悠久的历史和很高的竞技水平,与其职业棒球的发展有着紧密的联系。中国棒球联赛称不上真正意义的中国职棒联赛,只是看到了中国职棒的雏形,成为真正意义的职棒联赛,还需要有一定的时间进行棒球市场的培育与开发,只有队伍规模的壮大,球员水平的提高和拥有一定数量的球迷,真正气候的职业棒球才会实现,竞技水平才能赶超日本、韩国和中国台湾。 相似文献

The influence of a baseball glove on the positioning and grasping components of one-hand catching was studied under both vision impaired and unimpaired conditions. Skilled softball and baseball players (N = 20) caught tennis balls barehand and softballs with a fielder's glove. In half of the trials, a screen positioned alongside the subject's head blocked vision of the catching hand. All trials were videotaped and errors were categorized by type (position or grasp). Results indicated that with the glove performance was essentially perfect, regardless of the screen condition. Barehand grasping performance, however, was affected by the subject's inability to see his hand to a much greater extent than barehand positioning. We argue that the baseball glove functions to reduce both the positioning accuracy requirements and the grasp timing requirements in simple catching. Peripheral vision of the limb, however, is necessary for controlling the barehand grasp phase. 相似文献

The speed at which a player can swing a bat is central to the games of baseball and softball, determining, to a large extent,
the hit speed of the ball. Experimental and analytical studies of bat swing speed were conducted with particular emphasis
on the influence of bat moment of inertia on swing speed. Two distinct sets of experiments measured the swing speed of colege
baseball and fast-pitch softball players using weighted rods and modified bats. The swing targets included flexible targets,
balls on a tee and machine pitched balls. Internal mass alterations provided a range of inertial properties. The average measured
speeds, from 22 to 31 m s−1, are consistent with previous studies. Bat speed approximately correlates with the moment of inertia of the bat about a vertical
axis of rotation through the batter's body, the speed generally decreasing as this moment of inertia increases. The analytical
model assumes pure rotation of the batter/bat system about a vertical axis through the batter's body. Aerodynamic drag of
the batter's arms and the bat is included in the model. The independent variable is bat moment of inertia about the rotation
axis. There is reasonable agreement between the model and the measured speeds. Detailed differences between the two suggest
the importance of additional degrees of freedom in determining swing speed. 相似文献
