Music can enhance exercise-induced sympathetic dominancy assessed by heart rate variability

The researchers examined whether music affects the exercise-induced changes in the autonomic nervous system activity in twelve healthy female college students. Music was given according to subjects’ preferences using a vibroacoustic apparatus with low-pitch sounds. With music, ratio of low frequency to high frequency component of heart rate variability LF/HF was significantly increased after exercise as compared with before exercise. P < 0.01. By contrast, the changes in LH/HF were not significant without music. P> 0.05. It is suggested that after exercise in which sympathetic nerve activity is dominant, preferred music synchronizes with the activated physical response, further promoting the response and increasing sympathetic nerve activity.
