我国优秀蹦床运动员网上非技术性位移的初步研究 总被引：4，自引：1，他引：3
采用文献资料、现场观察、专家访谈、数理统计等研究方法 ,对我国高水平蹦床运动员网上水平位移现象进行初步研究。认为位移过大是影响成套动作稳定性及动作质量的重要因素之一 ;位移过大与起跳技术和连接技术不合理有关 ,也与运动员原有项目技能的负迁移影响有关 ;网上位移表现为一定的方向性 ,向前空翻类动作的水平位移略小于向后空翻类动作的位移。 相似文献

“筋斗”是中国毯子功的基本技艺。“筋斗”一词源自明代于慎行《榖山笔》揣拟的典故,认为“筋斗”源于“金斗”,典故出自《战国策.燕策》。“筋斗”一词有多种写法和念法,“筋斗”亦作“跟斗”、“斛斗”等,不一的字形,以及典故不明,皆表明了“筋斗”是一个谐音词。从语言的视角,“筋斗”一词源自于伊朗语汇,也透视出粟特文化的遗踪。 相似文献

Currently, all elite high jumpers use the Fosbury Flop technique with a curved approach. This suggests that the curved approach presents some clear advantage, although there is no general agreement upon the mechanism or the mechanics. This study aimed to determine the characteristics of the approach curve and to investigate how it contributes to the generation of somersault rotation. A simple theoretical model was used to demonstrate that a tightening approach curve would change the inward lean towards the centre of the curve into outwards lean. Three-dimensional video analysis was used to record the performances of two elite male high jumpers in competition. It was found that in each case the radius of the approach curve and the inward lean angle both decreased towards the end of the approach. The amount of outward lean angular velocity generated was shown to be a major proportion of the required somersault angular velocity for a jump. It was concluded that the main advantage of a curved approach was that it resulted in the generation of somersault velocity providing the curve tightened towards the end of the approach. 相似文献

A simulation model and a rigid body model are used to investigate twisting initiated during the take‐off or contact phase. It is shown that it is possible to produce a full twist solely by building up angular momentum in the arms during the contact phase. This method is only half as effective as building up momentum in the whole body during contact. The introduction of twist into a somersault changes the somersault rate by less than 1%. By timing arm adduction appropriately, it is possible to take advantage of nutation and boost the initial value of the tilt angle and so obtain a greater twist rate. Twist may be stopped by the action of piking, since the motion changes from the twisting mode to the wobbling mode of rigid body motion. Transition to and from these two modes can be used to increase or decrease the tilt angle and twist rate. 相似文献

柳玉烈、张峰治、李小双是世界优秀体操运动员，他们使用的前手翻空翻类高难动作在世界大赛中曾多次获得好名次。对三人完成的该类动作技术要点进行运动学对比分析，提供一批技术参数，并从定量和定性角度分析影响技术完成的主要参数间的相互关系，对动作技术特点、特征作了较详细地讨论。认为该动作技术还有一定潜力可挖掘，还需进一步完善、发展。 相似文献
