Abstract

The jump smash is badminton's most aggressive technical manoeuvre, which is often the key to winning a match. This paper aims to explore the neuromuscular control strategies of advanced and beginner players when jumping smash in different ways. Collecting sEMG and kinematic data from 18 subjects with different motor experiences when jumping smash. Nonnegative Matrix Factorization and K-Means clustering were used to extract muscle synergies and exclude irrelevant combined synergies. Uncontrolled manifold analysis was then used to explore the association between synergies and shoulder stability. In addition, motor output at the spinal cord level was assessed by mapping sEMG to each spinal cord segment. The study found that advanced subjects could respond to different jump smash styles by adjusting the coordinated activation strategies of the upper-limb and postural muscles. Long-term training can induce a rapid decrease in the degree of co-variation of the synergies before contact with a shuttlecock to better cope with an upcoming collision. It is recommended that beginners should focus more on training the coordination of upper-limb muscles and postural muscles.

运动经验对羽毛球跳砸中肌肉协同作用的影响分析

跳砸是羽毛球运动中最具攻击性的技术动作，往往是决定比赛胜负的关键。本文旨在探讨高级和初级运动员在以不同方式跳砸时的神经肌肉控制策略。本文收集了 18 名具有不同运动经验的受试者在跳砸时的 sEMG 和运动学数据。使用非负矩阵因式分解和 K-Means 聚类来提取肌肉协同作用，并排除不相关的组合协同作用。然后使用非受控流形分析来探讨协同作用与肩部稳定性之间的关联。此外，还通过将 sEMG 映射到每个脊髓节段来评估脊髓水平的运动输出。研究发现，高级受试者可以通过调整上肢和姿势肌肉的协调激活策略来应对不同的跳砸方式。长期训练可促使在接触毽子之前协同作用的共同变化程度迅速降低，从而更好地应对即将发生的碰撞。建议初学者应更加注重上肢肌肉和姿势肌肉的协调训练。

期刊介绍： Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
