A study on the physiological effects of auditory stimulus with heart rate variability during cycling

Music activates central emotions and promote the release of biochemical materials that could change the physiological activities. In this study, physiological and psychological effects of auditory stimuli were investigated by synchronizing the rhythm of music stimulus with that of HR during exercise. We propose a multi-time-scale autonomic regulation model that consists of trigger and accumulation effects with different timescales. As validation experiments, fifteen participants a 3-min-long music section repetitive five times (total 15-min) continuously during pedaling controlled workload. The results revealed that, the negative group significantly increased LF/HF ratio than positive group in every task (** p <; 0.01).
