| Abstract |
This study aimed to investigate the effect of music on autonomic nerve system (ANS) modulation after a high intensity aerobic exercise. Twenty-one healthy males (aged 22.5±1.0 yrs, mean±SD) were classified into Silent, Classic, and Rock, respectively. All participants performed a single bout of aerobic exercise (70%VO2max for 30 min) on treadmill, followed by 30 min recovery. During the post-exercise recovery (REC1, 0~10 min; REC2, 10~20 min; REC3, 20~30 min), heart rate variability (HRV) were recorded in soundproof chamber through Polar RS800CX while listening the different genres of music, and analysed in time-, frequency-, and nonlinear parameters. As results, LF/ HF ratio and LF nu were significantly different among groups in the entire recovery periods, in particular, Rock was significantly higher than the other groups (Rock>Classic>Silent) in post hoc test. On the contrary, HF/TP ratio and HF nu was significantly different among groups, particularly, Rock group was significantly lower than the other groups (Silent>Classic>Rock) in post hoc test; however, there were no significant differences between Silent and Classic groups. To summarize, auditory stimuli such as listening music significantly influence on ANS balance and its function during post-exercise recovery. Thus, listening quiet or relaxing music after a vigorous aerobic exercise has a positive effect on cardiac parasympathetic nerve reactivation in healthy young men. |
