本研究检测了心率变异性（HRV）生物反馈在生物反馈期间、反馈刚结束时以及随后实验室诱导的应激过程中对HRV指标的急性影响。18名面临工作相关压力的健康男性被随机分为HRV生物反馈组（BIO）或对照组（COM）。受试者在干预前（斯特鲁普1）和干预后（斯特鲁普2）完成一项改良的斯特鲁普任务。在斯特鲁普1中，两组对压力的生理反应相似。在斯特鲁普2中，COM组的反应与在斯特鲁普1中的反应相似：呼吸频率（RF）和心率（HR）增加，RMSSD和高频（HF）功率降低或有降低趋势，而低频（LF）功率无变化。BIO组在斯特鲁普2中的反应不同：RF增加且LF功率降低，但HR、RMSSD和HF功率无变化。在BIO组中，斯特鲁普2中的RMSSD比斯特鲁普1中的高。总之，HRV生物反馈在随后的休息期和实验室诱导的应激过程中都产生了短期的遗留效应，这表明干预后BIO组的高频迷走神经调节得以维持，而COM组的低频迷走神经调节得以维持。
This study examines the acute effect of heart rate variability (HRV) biofeedback on HRV measures during and immediately after biofeedback and during the following laboratory-induced stress. Eighteen healthy males exposed to work-related stress were randomised into an HRV biofeedback group (BIO) or a comparative group (COM). Subjects completed a modified Stroop task before (Stroop 1) and after (Stroop 2) the intervention. Both groups had similar physiological responses to stress in Stroop 1. In Stroop 2, the COM group responded similarly to the way they did to Stroop 1: respiratory frequency (RF) and heart rate (HR) increased, RMSSD and high frequency (HF) power decreased or had a tendency to decrease, while low frequency (LF) power showed no change. The BIO group responded differently in Stroop 2: while RF increased and LF power decreased, HR, RMSSD and HF power showed no change. In the BIO group, RMSSD was higher in Stroop 2 compared to Stroop 1. In conclusion, HRV biofeedback induced a short term carry-over effect during both the following rest period and laboratory-induced stress suggesting maintained HF vagal modulation in the BIO group after the intervention, and maintained LF vagal modulation in the COM group.
