Abstract

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.

摘要

随着运动竞赛的强度和身体需求不断提高,更快更好的恢复变得至关重要。本研究旨在评估在进行亚极量有氧运动恢复时,心率变异性生物反馈(HRVB)的效果。十名身体活跃的研究生参与了这项研究,该研究分为四个阶段进行:自由呼吸恢复下的运动、第一共振频率(RF)检测、第二 RF 检测和在恢复期间应用 HRVB 的运动。测量包括跑步和恢复时间、HRV 参数以及恢复/用力感知。结果表明,在恢复期间使用 HRVB 可改善心脏变异性(RRmean、SDNN、RMSSD 和 LF;p<0.01)。HRVB 还降低了恢复时间(p<0.05),并似乎改善了恢复感知(p=0.087)。此外,应用 HRVB 时,运动时间(p<0.01)和感知的身体用力(p<0.05)更高。HRVB 为高强度有氧运动后的心理生理适应提供了有益的益处,不仅对竞技运动员,而且对普通人群也是如此。
