Key result
HRV biofeedback after submaximal exercise reduces recovery time and improves cardiac variability versus free breathing.
Why the study?
As intensity and physical demands continue to rise in sport competition, faster and better recovery is essential, prompting assessment of the effects of HRV biofeedback during recovery from submaximal aerobic exercise.
Does HRV biofeedback improve recovery time and cardiac variability in physically-active individuals recovering from submaximal aerobic exercise?
Does HRV biofeedback improve recovery time and cardiac variability in physically-active individuals recovering from submaximal aerobic exercise?
Applying heart rate variability biofeedback during recovery from intensive aerobic exercise improves cardiac variability and reduces recovery time.

Hypothesis-generating for faster recovery in active adults; prospective RCTs needed before clinical use.
As intensity and physical demands continue to rise in sport competition, faster and better recovery becomes essential. The aim of this study was to assess the effects of HRV biofeedback (HRVB) while recovering from a submaximal aerobic exercise. Ten physically-active graduate students participated in the study, which was conducted in four sessions: exercise with free-breathing recovery, first resonance frequency (RF) detection, second RF detection, and exercise applying HRVB during recovery. Measurements included time spent running and recovering, HRV parameters, and recovery/exertion perceptions. The results indicate that using HRVB during recovery improves cardiac variability (RRmean, SDNN, RMSSD and LF; p < 0.01). HRVB also lowers recovery time (p < 0.05) and seems to be improving the perception of recovery (p = 0.087). Moreover, time spent exercising (p < 0.01) and perceived physical exertion (p < 0.05) were higher when applying HRVB. The improvement in the psychophysiological adaptation after intensive aerobic exercise provided by the HRVB is a valuable benefit, not only for competition-driven athletes, but also for the general population.

Pérez-Gaido et al. (2021) studied Healthy physically active individuals (n=10). HRV biofeedback (HRVB) vs. Free-breathing recovery was evaluated on Recovery time (time to reach 50% HR) (p=0.038). HRV biofeedback applied during recovery from submaximal aerobic exercise reduced recovery time and improved cardiac variability compared to free-breathing recovery.
