Does auditory stimulation with heavy metal music alter cardiac autonomic regulation in healthy women?
p-value: p=0.05
Acute exposure to heavy metal music reduces heart rate variability, suggesting a shift toward increased sympathetic autonomic regulation.
Acute heavy metal exposure was associated with reduced HRV in healthy women; hypothesis-generating and should not yet change practice.
Aim. Investigate the acute effects of heavy metal musical auditory stimulation on cardiac autonomic regulation. Material and methods. This is a prospective study conducted on 22 healthy women between 18 and 30 years old. All procedures were performed in the same soundproof room. The volunteers remained at rest for 20 minutes and subsequently were exposed to heavy metal (75-84 dB) music for 20 minutes. We analysed the following HRV indices: SDNN, RMSSD, pNN50, LF, HF and LF/HF ratio, RRTri, TINN, SD1, SD2 and SD1/SD2 ratio. Results. During exposure to heavy metal music auditory stimulation we observed that the LF (ms2 ) tended to increase (p=0,06) and reduce HF (nu) (p=0,07) and the LF/HF ratio increased (p=0,05). No significant changes were found for SDNN, pNN50, RMSSD, SDNN/RMSSD ratio, TINN, RRTri, SD1, SD2 and SD1/SD2 ratio. Conclusion. Auditory stimulation with the selected heavy metal musical style acutely decreased HRV.

Nogueira et al. (2016) conducted an observational in Healthy (n=22). Heavy metal music auditory stimulation vs. Resting without music was evaluated on Heart rate variability (LF/HF ratio) (p=0.05). Auditory stimulation with heavy metal music acutely decreased heart rate variability, as indicated by an increase in the LF/HF ratio (p=0.05).
