Abstract

Purpose: To study the effect on HRV of archer athletes one day before competition after three different abdominal respiratory frequencies.

Methods: Eight elite archers performed three different respiratory frequency tests, HRV were recorded in pre-, during, and post-frequency control in frequency 16 (F16 group, n = 8), 8 (F8 group, n = 8), and 5 (F5 group, n = 8) times per minute, and hoped to find a respiratory adjust way to reduce stress. RMSSD, RR_triangular index, TP, VLF, LF, HF and LF/HF were analyzed to describe the effect of respiratory frequency.

Result: The average RR separate, RR_triangular index and HF showed no significant change in three respiratory frequency (P > 0.05); LF increased significantly in F16 group, but LP of F8 and F5 group increased first then reduced (P < .05); VLF rose in F8 and F5 group (P < .05, respectively), the LF/HF has the similar change as the LF in all the groups.

Conclusion: The F16 group increased equilibrium of sympathetic and pneumogastric nerve system; F8 increase excitability of sympathetic nerve; mental fatigue remission in F5.

Keywords: Abdominal breathing; Archer athletes; HRV; before the competition.
