Abstract

Swing to strength hold elements are important for a top ranking on still rings, require a high level of upper body strength of the gymnasts and have not yet been scientifically investigated. Therefore, the aim of this study was to determine force requirement profiles for these elements using a dynamometric measuring system. Two force sensors attached to the cables of each ring and synchronised with video recorded the forces exerted by the gymnast. For eight swing to strength hold elements (Uprise backward to support scale straddled, Uprise backward to swallow, Uprise backward to cross, Honma to cross, Uprise backward to support scale, Kip to cross, Back kip to swallow and Uprise backward to inverted cross), the variables maximal force (F_max), minimal force (F_min), time over F_hold (t_1-3), rate of maximal force development (RFD) and impulse (p) were analysed. Honma to cross shows the highest force requirements (Median: F_max = 120.4% BW, F_min = 109.8% BW, t_1-3 = 882 ms, RFD = 143.93% BW/s, p = 9.85% BWs) whereas back kip to swallow shows the least (F_max = 102.3% BW, RFD = 34.99% BW/s and p = 0.84% BW/s). The biomechanical demand profiles can be used to provide feedback to coaches and gymnasts. In future research, they should be extended with kinematic and electromyographic data.

男子艺术体操静止吊环上从摆动到力量保持元素的力要求曲线。

摆动到力量保持是在静止吊环上获得最高排名的重要因素，对体操运动员的上肢力量要求很高，但目前尚未进行科学研究。因此，本研究的目的是利用测力系统确定这些动作的力量需求曲线。两个力传感器连接在每个吊环的缆绳上，并与视频同步记录体操运动员施加的力。对 8 个摆动到力量保持动作（Uprise 后向支撑秤跨骑、Uprise 后向吞咽、Uprise 后向交叉、Honma 交叉、Uprise 后向支撑秤、Kip 交叉、Back kip 吞咽和 Uprise 后向倒交叉）的最大力（Fmax）、最小力（Fmin）、超过 Fhold 的时间（t1-3）、最大力发展率（RFD）和冲量（p）等变量进行了分析。本马到交叉显示了最高的力量要求（中位数：Fmax = 120.4% BW，Fmin = 109.8% BW，t1-3 = 882 ms，RFD = 143.93% BW/s，p = 9.85% BWs），而后开式吞咽显示出最小的力量需求（Fmax = 102.3% BW，RFD = 34.99% BW/s，p = 0.84% BW/s）。生物力学需求曲线可用于向教练和体操运动员提供反馈。在未来的研究中，应利用运动学和肌电图数据对其进行扩展。

期刊介绍： Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
