Abstract

Introduction. Heart rate variability (HRV) is considered a marker of autonomic nervous system (ANS) function and a biomarker of interest in evaluating nervous system function following traumatic brain injury. This study validates prior research with larger sample sizes and proposes a model for establishing baseline HRV reactivity in healthy participants. Methods. Sixty-two healthy collegiate athletes were recruited for this study. Following informed consent, they were evaluated supine using the Elite HRV CorSense monitor and platform to record low frequency/high frequency (LF/HF) ratio and root means square of successive differences (RMSSD) over 5 min. A bag of ice was placed on their face, then RMSSD and LF/HF ratio were collected over three successive 1-min intervals. Results. RMSSD was elevated at 1 and 2 min (+47.4 ms, p < .0001; +16.5 ms, p = .014) following face cooling and fell to baseline at 3 min (+4.6 ms, p = .52). LF/HF ratio decreased following face cooling at 2 and 3 min (change from rest %: 2 min, −33%, p = .007; 3 min, −50%, p = < .0001). Conclusion. The Elite HRV platform can detect an elevation in RMSSD in the first minute following face cooling with a return to baseline in the second and third minutes. It can also detect a consistent decrease in LF/HF following face cooling.

利用潜水员反射对心率变异性的移动评估

介绍心率变异性（HRV）被认为是自主神经系统（ANS）功能的标志物，也是评估创伤性脑损伤后神经系统功能的生物标志物。这项研究用更大的样本量验证了先前的研究，并提出了一个在健康参与者中建立基线HRV反应性的模型。方法。本研究招募了62名健康的大学生运动员。知情同意后，使用Elite HRV CorSense监测仪和平台对他们进行仰卧评估，以记录5分钟内的低频/高频（LF/HF）比和连续差异均方根（RMSSD）。在他们的脸上放一袋冰，然后在三个连续的1分钟间隔内收集RMSSD和LF/HF比。后果面部冷却后1分钟和2分钟RMSSD升高（+47.4 ms，p<.0001；+16.5 ms，p=.014），3分钟降至基线（+4.6 ms，p=.52）。面部冷却后2分钟和3分钟LF/HF比率下降（与休息相比变化%：2分钟，−33%，p=.007；3分钟，−50%，p=<.0001）。结论。Elite HRV平台可以在面部冷却后的第一分钟检测到RMSSD的升高，并在第二分钟和第三分钟返回基线。它还可以检测到面部冷却后LF/HF的持续下降。

期刊介绍： NeuroRegulation is a peer-reviewed journal providing an integrated, multidisciplinary perspective on clinically relevant research, treatment, reviews, and public policy for neuroregulation and neurotherapy. NeuroRegulation publishes important findings in these fields with a focus on electroencephalography (EEG), neurofeedback (EEG biofeedback), quantitative electroencephalography (qEEG), psychophysiology, biofeedback, heart rate variability, photobiomodulation, repetitive Transcranial Magnetic Simulation (rTMS) and transcranial Direct Current Stimulation (tDCS); with a focus on treatment of psychiatric, mind-body, and neurological disorders. In addition to research findings and reviews, it is important to stress that publication of case reports is always useful in furthering the advancement of an intervention for both clinical and normative functioning. We strive for high quality and interesting empirical topics presented in a rigorous and scholarly manner. The journal draws from expertise inside and outside of the International Society for Neurofeedback & Research (ISNR) to deliver material which integrates the diverse aspects of the field, to include: *basic science *clinical aspects *treatment evaluation *philosophy *training and certification issues *technology and equipment
