Abstract

This study aimed to investigate the effect of hand muscle fatigue on finger control and force efficiency during piano performance, which is crucial for skilled piano playing among professional pianists engaged in prolonged periods of high-intensity practice or concert preparation. Thirty-one professional pianists were recruited as participants. This study was divided into three sequential experimental parts: pre-fatigue test, fatigue protocol, and post-fatigue test. Each participant was assigned eight piano skills and instructed to perform two fatigue tasks: finger extension and finger grasping exercises. The study recorded and analyzed the finger force of professional pianists using a sensor-embedded kinetic assessment piano system; wrist movements were assessed using a three-dimensional motion capture system. Paired t-tests were used to determine the differences between the pre- and post-tests. The findings showed that the average peak striking force of most fingers in Chords 1, 2, 4, 5, 6, and 7 decreased significantly after the fatigue task, indicating a reduction in the finger-striking force following fatigue across the various chord fingerings. The analysis of wrist movements demonstrated strategic adjustments made by pianists after experiencing fatigue, particularly in the ulnar/radial deviation movements. This study highlights the influence of muscle fatigue on finger control and wrist movements of pianists across different fingerings. We recommend that pianists focus on strengthening the extrinsic and intrinsic muscles of the hand and the muscle groups responsible for controlling ulnar/radial movements to mitigate the effects of muscular fatigue on hand performance.

诱发外源性和内源性手和前臂肌肉疲劳对钢琴演奏中手指力控制的影响。

本研究旨在探讨手肌疲劳对钢琴演奏过程中手指控制和力量效率的影响，这对从事长时间高强度练习或音乐会准备的专业钢琴家的熟练钢琴演奏至关重要。招募了31名专业钢琴家作为参与者。本研究分为三个连续实验部分：疲劳前试验、疲劳方案试验和疲劳后试验。每位参与者被分配了八种钢琴技能，并被要求完成两项疲劳任务：手指伸展和手指抓握练习。采用嵌入式传感器钢琴动力学评估系统对专业钢琴家的手指受力进行了记录和分析；使用三维运动捕捉系统评估手腕运动。配对t检验用于确定前后检验之间的差异。结果表明，在疲劳任务后，和弦1、2、4、5、6和7中大多数手指的平均峰值敲击力显著下降，表明疲劳后手指敲击力在各个和弦指法中都有所降低。对手腕运动的分析表明钢琴家在经历疲劳后会进行战略性调整，特别是在尺侧/桡骨偏移运动中。本研究强调肌肉疲劳对不同指法钢琴家手指控制和手腕运动的影响。我们建议钢琴家着重加强手部的外在和内在肌肉以及负责控制尺骨/桡骨运动的肌肉群，以减轻肌肉疲劳对手部演奏的影响。

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."
