Abstract :
A biofeedback program receives attention as an intervention program for athletes to regulate their
psychological state. Objectives. The purpose was to apply for a heart rate variability (HRV) biofeedback training
program and validate its effectiveness for racket sports players. Objectives. The purpose was to apply a heart rate
variability (HRV) biofeedback training program and validate its effectiveness for racket sports players. Methods. he
participants were eight elite sport athletes (three men and five women): five squash players and three tennis players.
The HRV biofeedback training program consisted of ten sessions in which the participants performed paced breathing
for 10 minutes (e.g., 5-second inspiration and 5-second expiration). The means and standard deviations of the collected
data were calculated, and the Wilcoxon signed-rank test was performed using SPSS windows 18.0. Results. Changes
in HRV by the biofeedback training were significant. Standard Deviation of Normal to Normal (SDNN; Z = -2.38, p
= 0.017) in time domain and Low Frequency (LF, Z = -2.52, p = 0.12) and the ratio of LF to High Frequency (HF; Z
= -2.52, p = 0.12) in frequency domain were increased. Conclusion. The present study provides empirical results
needed to expand HRV biofeedback training research for the performance enhancement program of athletes.
