Methods to enhance the ergogenic effects of music are of interest to athletes of all abilities. The aim of this pilot study was to investigate the ergogenic effects of two commercially available methods of music augmentation: auditory beats and vibrotactile stimulation. Six male and five female cyclists/triathletes cycled for 7 minutes at three different intensities: a rate of perceived exertion (RPE) of 11 ("light"), RPE of 15 ("hard"), and a 7-minute time-trial. Before each 7-minute bout of cycling, participants listened to 10 minutes of self-selected music (MUS), or the same music with the addition of either isochronic auditory beats (ABS) or vibrotactile stimulation via SUBPAC (VIB). MUS, ABS and VIB trials were performed in a randomized order. Power output was measured during cycling and felt arousal and feeling scores were recorded at timepoints throughout the protocol. The results found the augmented MUS interventions did not influence power output with no significant main effect of trial ( = 0.44, η = 0.09) or trial × cycling intensity interaction ( = 0.11, η = 0.20). Similarly, both felt arousal and feeling scores were unchanged between the MUS, ABS, and VIB trials ( > 0.05). In conclusion, this pilot study indicated an ineffectiveness of the ABS and VIB to affect subsequent 7-min cycling performance compared to self-selected MUS alone.
提高音乐促力效应的方法受到了各水平运动员的关注。这项初步研究的目的是调查两种市售音乐增强方法的促力效应：听觉节拍和振动触觉刺激。六名男性和五名女性自行车运动员/铁人三项运动员以三种不同强度骑行7分钟：自感用力度（RPE）为11（“轻度”）、RPE为15（“重度”）以及进行7分钟的计时赛。在每次7分钟的骑行之前，参与者聆听10分钟自选音乐（MUS），或聆听添加了等时听觉节拍（ABS）的相同音乐，或通过SUBPAC进行振动触觉刺激的相同音乐（VIB）。MUS、ABS和VIB试验以随机顺序进行。在骑行过程中测量功率输出，并在整个试验过程中的各个时间点记录感觉唤醒和感觉评分。结果发现，增强的MUS干预措施并未影响功率输出，试验没有显著的主效应（F = 0.44，η² = 0.09），试验×骑行强度交互作用也不显著（F = 0.11，η² = 0.20）。同样，在MUS、ABS和VIB试验之间，感觉唤醒和感觉评分均未改变（p > 0.05）。总之，这项初步研究表明，与单独的自选MUS相比，ABS和VIB对随后7分钟的骑行表现没有影响。
