对新规则下直拍进攻型打法发展趋势的研究     

赵霞  苏丕仁  张浩 《北京体育大学学报》2006,29(1):122-124

直拍进攻型打法曾经是我国乒坛的主流打法,由于缺乏创新,在近10多年一直不太景气.但是,直拍进攻型打法有其特定的优势,具有很强的抗争能力,只要创新技术、加强实力,就能登上世界乒坛的最高峰;诚然,它自身的确也存在着很多问题,加上11分赛制和无遮挡发球的实行,必定会给这种打法带来一些影响(正负双方面).因此,在新形势下对直拍进攻型打法进行进一步的深入剖析和探讨,成为我国乒坛亟待解决的课题.通过对世界优秀男子直拍进攻型打法选手的技战术进行统计与分析,并走访乒乓界权威人士和有关专家,对新规则带来的一些问题和该打法今后的发展趋势进行深入分析与探讨,为进一步提高我国直拍进攻型打法的技术水平提供科学理论和参考依据.  相似文献

A kinematic analysis of the spine during rugby scrummaging on natural and synthetic turfs     

Ramesh Swaminathan  Jonathan M. Williams  Michael D. Jones 《Journal of sports sciences》2016,34(11):1058-1066

Artificial surfaces are now an established alternative to grass (natural) surfaces in rugby union. Little is known, however, about their potential to reduce injury. This study characterises the spinal kinematics of rugby union hookers during scrummaging on third-generation synthetic (3G) and natural pitches. The spine was sectioned into five segments, with inertial sensors providing three-dimensional kinematic data sampled at 40 Hz/sensor. Twenty-two adult, male community club and university-level hookers were recruited. An equal number were analysed whilst scrummaging on natural or synthetic turf. Players scrummaging on synthetic turf demonstrated less angular velocity in the lower thoracic spine for right and left lateral bending and right rotation. The general reduction in the range of motion and velocities, extrapolated over a prolonged playing career, may mean that the synthetic turf could result in fewer degenerative injuries. It should be noted, however, that this conclusion considers only the scrummaging scenario.  相似文献   

Sprint and jump performances do not determine the promotion to professional elite soccer in Spain, 1994–2012     

Raul Martinez-Santos  Daniel Castillo 《Journal of sports sciences》2016,34(24):2279-2285

ABSTRACT

The aims of this study are (a) to describe the evolution of neuromuscular performance over an 18 year period within a Spanish elite reserve team; (b) to check if there were any relation between the playing position and sprint and jump performances and (c) to look into the alleged impact of this factor on the top playing level attained by the soccer players. We considered the physical tests (5 m and 15 m sprint times and countermovement jump (CMJ) height) made by 235 players enrolled in the reserve team of the Club from 1994 to 2012 and the highest competitive-level they achieved: Spanish first (n = 39) and second divisions (n = 36) and semi-professional (n = 160). Furthermore, the players were classified according to their playing positions. The main findings were a very-likely/most-likely lower neuromuscular performance (ES = 0.48–0.68, small to moderate) in the last six-season term (2006–2012) than in the first term (1994–2000); possibly/very-likely lower performances in sprinting and CMJ (ES = 0.22–0.55, small) by central defenders (CDs) and midfielders than by other playing positions; very-likely better performances in sprinting and jumping by first and second divisions central defenders than by semi-professional central defenders (ES = 0.90–1.02, moderate). Sprint and jump performances are not a relevant physical parameter to promote to the top level of soccer in Spain except for one in six of the playing positions: CDs.  相似文献   

钢琴教学中的读谱方法     

王兢莉 《襄樊职业技术学院学报》2011,10(5):120-122

读谱是对音乐作品的感性认识,也是对作曲家创作意图的直接感受。在钢琴读谱的过程,建立视、听、唱、弹等各项感官协调的联系,完成各种动作形成弹奏的定势,进行科学的读谱训练,钢琴的弹奏才能显得优美完整。  相似文献
