Effect of Different Dance Rhythms on the Recovery Period of the Autonomic Nervous System

The purpose of this study was to investigate the impact of various dance rhythms on heart rate variability (HRV), to determine the relationship between dance rhythms and HRV during the recovery period, and to provide reliable recommendations for dance interventions in the field of cardiovascular disease.

A total of 160 college students enrolled at Yan'an University as of September 1, 2023 were randomly selected and assigned to 3 groups. Each group underwent dance interventions at rhythms of 60 beats per minute (bpm), 100 bpm, and 140 bpm, respectively, conducted in 3 sessions, each lasting 5 minutes. Heart rate recovery and HRV data were collected before and after the tests for statistical analysis.

Analysis of HRV indicators before the dance rhythm intervention showed no statistically significant difference between men and women (P > .05). However, HRV and the standard deviation of normal-to-normal intervals (SDNN) during the recovery period were statistically significantly different between men and women under different dance rhythm interventions (P < .05). Moreover, HRV and SDNN values after the intervention at 140 bpm were significantly lower than those after the interventions at 60 bpm and 100 bpm (P < .05).

These study results demonstrate that dance rhythm significantly affected HRV. This information may be potentially helpful in informing further research studies for dance interventions in the field of cardiovascular diseases.
