Abstract
Abstract: Garner, C, Nachtegall, A, Roth, E, Sterenberg, A, Kim, D, Michael, T, and Lee, S. Effects of movement sonification auditory feedback on repetitions and brain activity during the bench press. J Strength Cond Res 38(12): 2022-2028, 2024-Auditory stimulation and feedback have been found to enhance aspects of motor performance such as motor learning, sense of agency, and movement execution. While music is the most common form of auditory stimulation during exercise, movement sonification (MoSo) may better facilitate motor performance through its use of music elements representing dynamic movements. Despite evidence of MoSo's benefits to motor performance, little is known about MoSo's influence on resistance exercise. The purpose of this research was to investigate the effects of MoSo auditory feedback on repetitions and brain activity during bench press.

摘要:Garner, C, Nachtegall, A, Roth, E, Sterenberg, A, Kim, D, Michael, T, and Lee, S.运动声音听觉反馈对卧推运动重复和大脑活动的影响。研究发现,听觉刺激和反馈可以增强运动学习、代理感和运动执行等方面的运动表现。[J] .中国肌肉杂志,38(12):2022- 2028,2024。虽然音乐是运动中最常见的听觉刺激形式,但运动声效(MoSo)可以通过使用代表动态运动的音乐元素来更好地促进运动表现。尽管有证据表明MoSo对运动表现有益,但对MoSo对阻力运动的影响知之甚少。本研究的目的是探讨MoSo听觉反馈对卧推运动中重复动作和大脑活动的影响。20人在3种声音条件下(无声音、自选音乐和MoSo)进行卧推失败。测量重复最大值(RM),用β功率谱密度(PSD)和额叶α不对称(FAA)分析脑活动。采用单向重复测量方差分析(ANOVA)来比较不同条件下的数据。为了更深入地了解卧推时的大脑活动,我们使用声音和时间点作为自变量,进行了双向重复测量方差分析,以调查β PSD和FAA随时间的变化。单因素方差分析显示,MoSo组的FAA显著高于音乐组和无声音组;然而,两组间RM和β PSD无统计学差异。双向方差分析显示,当卧推重复接近失败时,β PSD和FAA显著增加。我们的研究表明,MoSo听觉反馈可能不会提高卧推重复,但它可能比听音乐更好地增加卧推时的大脑活动。
期刊介绍:
The editorial mission of The Journal of Strength and Conditioning Research (JSCR) is to advance the knowledge about strength and conditioning through research. A unique aspect of this journal is that it includes recommendations for the practical use of research findings. While the journal name identifies strength and conditioning as separate entities, strength is considered a part of conditioning. This journal wishes to promote the publication of peer-reviewed manuscripts which add to our understanding of conditioning and sport through applied exercise science.
