射箭是一项技术性很强的体育项目,射箭技术的核心是用力。近年来世界水平迅速提高其原因是多方面的,但动作用力结构的合理性,已成为在技术上研究的中心问题。就目前技术动作看,似乎用力僵硬、动作松散、节奏不强是影响创造高成绩的障碍。但仔细推敲这只不过是现象,实际是组成射箭动作的各用力环节结构不合理所引起的。那么,哪些部位是构成射箭动作的主要用力环节呢?我们认为主要有两方面:一、持弓臂的用力,二、撒放动作的用力结构。剖析和探讨这两个主要技术环节用力结构的合理性,这对于我们选择适宜的训练途径,迅速提高我国射箭运动水平是有其重要意义的。 相似文献

目的：探讨振动杆训练对射箭运动员固势-撒放阶段稳定性的影响。方法：以26名射箭运动员为研究对象,随机分为实验组（振动杆）和对照组,每组13名。对照组只进行常规射箭力量训练,实验组在常规射箭力量训练的基础上再进行振动杆训练（每次训练30 min,每周3次,共8周）,所有运动员在训练前及训练8周后分别测试积分肌电值（iEMG）、12支箭固势-撒放时间、黄心命中率等指标,并进行比较。结果：训练8周后,仅实验组射箭运动员双侧肩关节的前锯肌、上斜方肌、中斜方肌、下斜方肌、菱形肌和肩胛下肌的iEMG、固势-撒放时间、黄心命中率,较训练前有显著性差异（P＜0.05）。组间比较时,实验组双侧肩关节的前锯肌、上斜方肌、中斜方肌、下斜方肌、菱形肌和肩胛下肌的iEMG和肌肉活性、固势-撒放时间、黄心命中率,与对照组比较均具有显著性差异（P＜0.05）。结论：振动杆练习能显著提高肩胛骨主要稳定肌的激活水平,缩短固势-撒放时间以及提高黄心命中率,可作为射箭运动员体能训练的一种有效辅助手段。 相似文献

Competition results in sport archery depend to a great extent upon the optimal combination of bow-arrow-archer system parameters.
A significant part of bow tuning is vertical adjustment, the aim of which is to give an arrow zero angle of attack. It is
conducted in a long and complicated manner and error correction takes a lot of time and effort. The goal of the research was
to create an analytical method to determine an optimal combination of bow parameters, which ensures zero angle of attack for
an arrow launched from a string. Mechanical and mathematical models of bow and arrow geometry in the vertical plane in braced
and drawn situations were investigated. An asymmetrical scheme, rigid beams, concentrated elastic elements and elastic string
were the main features of the model. Numerical results of a computer simulation are presented in tabular and graphical form,
which makes it easy for sportsmen and coaches to use. 相似文献

Recurve archery is an Olympic sport that requires extreme precision, upper body strength and endurance. The purpose of this research was to quantify how postural stability variables both pre- and post-arrow release, draw force, flight time, arrow length and clicker reaction time, collectively, impacted on the performance or scoring outcomes in elite recurve archery athletes. Thirty-nine elite-level recurve archers (23 male and 16 female; mean age?=?24.7?±?7.3 years) from four different countries volunteered to participate in this study prior to competing at a World Cup event. An AMTI force platform (1000Hz) was used to obtain centre of pressure (COP) measurements 1s prior to arrow release and 0.5s post-arrow release. High-speed footage (200Hz) allowed for calculation of arrow flight time and score. Results identified clicker reaction time, draw force and maximum sway speed as the variables that best predicted shot performance. Specifically, reduced clicker reaction time, greater bow draw force and reduced postural sway speed post-arrow release were predictors of higher scoring shots. It is suggested that future research should focus on investigating shoulder muscle tremors at full draw in relation to clicker reaction time, and the effect of upper body strength interventions (specifically targeting the musculature around the shoulder girdle) on performance in recurve archers. 相似文献

A predominant archery coaching tenet holds that the most effective means of releasing the bow string is by relaxation of the finger flexor muscles without activation of finger extensors. To evaluate the validity of this view, EMG patterns of the flexor digitorum superficialis and extensor digitorum muscles of the draw arm were examined using surface EMG electrodes in 15 highly skilled archers as each performed six shots. Each archer displayed consistent EMG patterns from shot-to-shot and two distinct flexor-extensor patterns were exhibited by the sample. The first, characterized by eight of the archers, supported the relaxation principle. For these archers, both flexor and extensor digitorum activity decreased markedly immediately prior to or at arrow release. The second pattern, characteristic of the remaining seven archers, contradicted the coaching tenet. While the flexor digitorum pattern was essentially the same as that described for the first pattern, the extensor digitorum displayed a marked increase in activity just prior to release, indicating that string release was facilitated by an active extension of the fingers. It was concluded that highly skilled archers do not predominantly reflect a release consistent with the coaching canon and that factors other than the string release mechanism discriminate the performances of skilled archers. 相似文献

AbstractThis paper aims to interrogate the key policy factors behind South Korea’s archery success. Based on our review on the history of Korean archery, two additional key elements in terms of organization and administration were also included to form the analytical framework of this research, aside from Green and Houlihan’s four key policy elements. Our analytical framework is thus comprised of two background elements for elite sport development – the organizational structure and administration, and four areas of elite sport policy. According to our analytical framework, this paper highlights four key policy dimensions that have influenced South Korea’s archery success, as follows: (i) establishment of the Korean Archery Association (KAA) and the involvement of business elites; (ii) emergence of potential full-time archers by the identification of, and the support for, young talented athletes; (iii) developments in sport science, coaching, and facilities/equipment; and (iv) the provision of more systematic competition opportunities for elite-level archers. In summary, the success of Korean archers might be closely linked to the result of the KAA’s staunch strategy and policy initiatives encouraged by the government for international sporting success and the way in which the organization has paid more salient attention to the policy commitments as noted above. 相似文献
