The assessment of heart rate variability (HRV) upon waking has been proposed as a method to evaluate mental health; however, owing to large individual differences among athletes, it is unclear whether HRV is adequate to predict mental health decline. In this study, we sought to establish this by evaluating HRV upon awakening in one athlete over 20 months. We assessed mental health once a month by calculating the depression index. In addition, self-reported training load and psychological fatigue index were assessed as psychological indices for athletes. Heart rate and HRV were each measured three days per week in both resting (supine) and standing (upright) positions. The results showed that orthostatic HRV upon waking had moderate linear relationships with the scores on the depression index and psychological fatigue index. By contrast, self-reported training load, a measure of physical stressor, was not associated with HRV. The findings suggest that the repeated assessment of HRV upon waking and mental health indicators may be useful in preventing mental health decline in athletes.
睡醒时心率变异性（HRV）的评估已被提出作为评估心理健康的一种方法；然而，由于运动员之间存在很大的个体差异，因此尚不清楚 HRV 是否足以预测心理健康下降。在这项研究中，我们通过评估一名运动员在 20 个月期间睡醒时的 HRV 来确定这一点。我们通过计算抑郁指数来每月评估一次心理健康。此外，还评估了自我报告的训练负荷和心理疲劳指数作为运动员的心理指标。每周测量三次心率和 HRV，分别在休息（仰卧）和站立（直立）位置。结果表明，睡醒时的直立位 HRV 与抑郁指数和心理疲劳指数的评分呈中度线性关系。相比之下，自我报告的训练负荷，一种身体应激源的测量，与 HRV 无关。研究结果表明，反复评估睡醒时的 HRV 和心理健康指标可能有助于预防运动员的心理健康下降。
