Impact of Musical Auditory Stimulation Applied during and after Aerobic Exercise on Vagal Reentry in Recovery Period

AIM: To investigate the influence of musical auditory stimulation, through classical music, applied during and after submaximal aerobic exercise on vagal reentry in the immediate recovery period. MATERIALS AND METHODS: 33 adult volunteers young and healthy, between 18 and 30 years underwent a protocol divided into three phases: I) Maximal Test procedure for determining the load that was applied in stages II and III; II) Control Protocol: rest for 15 minutes in the supine position, followed by 30 minutes of aerobic exercise on a treadmill (5 minutes at a speed of 6.0 km/h followed by 25 minutes with 60% of Vmax + 1% slope) and finally recovery standing for 3 minutes on the treadmill; III) Music protocol: similar to the control protocol, but with exposure to musical auditory stimulation during exercise and recovery phase. For analysis of the vagal reentry were analyzed RMSSD index of 30 seconds and recovery heart rate. RESULTS: No differences were found between protocols and interaction moments vs. protocols (p > 0.05) both RMSSD index of 30 seconds and for recovery heart rate, but differences were found between the moments of each protocol (p <0.05). Regarding Δ1 and Δ2, significant differences were observed between Δ1 relative to Δ2 (p <0.05) in both protocols, between Δ1music and Δ1control and between Δ2music and Δ2control. CONCLUSION: The musical auditory stimulation, through classical music, applied during and after submaximal aerobic exercise was not able to influence the vagal reentry in the immediate recovery period.
