Resting heart rate variability (HRV) may be a useful index of both brain-based executive function and general health. Our purpose in this study was to quantify relationships among HRV, perceptual-motor performance metrics, and wellness survey responses. A cohort of 32 male Reserve Officer Training Corp (ROTC) cadets completed a dual-task upper extremity reaction time (UERT) test, two tests of whole-body reactive agility, and a 10-item wellness survey that produced a 0-100 Overall Wellness Index (OWI). We averaged participants' resting HRV measurements twice per week over 10 weeks to derive an intra-individual grand mean (HRV-IIGM) and over a series of days we calculated an intra-individual coefficient of variation (HRV-IICV). We used median values for the two HRV metrics (HRV-IIGM and HRV-IICV) to separate the cadets into equal-sized high and low HRV groups to form the dependent variable for logistic regression analyses. We found a significant inverse relationship between HRV-IIGM and HRV-IICV ( = -0.723, < .001). Differences in UERT in the left versus right visual hemifields (L-R Diff) and OWI scores were strongly related to both HRV-IIGM ≤ 4.49 and HRV-IICV ≥ 6.95%. Logistic regression models that included L-R Diff and OWI showed 71% classification accuracy for HRV-IIGM (Model χ2 [2] = 12.47, = .002, Nagelkerke = 0.430) and 81% classification accuracy for HRV-IICV (Model χ2 [2] = 14.88, = .001, Nagelkerke = 0.496). These findings suggest that resting HRV, perceptual-motor efficiency, and overall wellness are highly interrelated, supporting a multi-factor biopsychosocial assessment to guide the design and implementation of interventions to maximize operational effectiveness for ROTC cadets and other military personnel.
静息心率变异性（HRV）可能是大脑执行功能和整体健康的有用指标。我们在这项研究中的目的是量化 HRV 与感知运动表现指标和健康调查应答之间的关系。一组 32 名预备役军官训练团（ROTC）学员完成了一项双任务上肢反应时间（UERT）测试、两项全身反应敏捷性测试和一项包含 10 个项目的健康调查，该调查产生了 0-100 整体健康指数（OWI）。我们在 10 周内每周两次平均参与者的静息 HRV 测量值，以得出个体内平均（HRV-IIGM），并在一系列天数内计算个体内变异系数（HRV-IICV）。我们使用两个 HRV 指标的中位数（HRV-IIGM 和 HRV-IICV）将学员分为大小相等的高 HRV 和低 HRV 组，形成逻辑回归分析的因变量。我们发现 HRV-IIGM 与 HRV-IICV 之间存在显著的负相关关系（ = -0.723， <.001）。UERT 在左与右视半视野（L-R Diff）之间的差异和 OWI 得分与 HRV-IIGM ≤ 4.49 和 HRV-IICV ≥ 6.95%均有强烈关系。包含 L-R Diff 和 OWI 的逻辑回归模型对 HRV-IIGM 的分类准确率为 71%（模型 χ2[2] = 12.47， =.002，Nagelkerke = 0.430），对 HRV-IICV 的分类准确率为 81%（模型 χ2[2] = 14.88， =.001，Nagelkerke = 0.496）。这些发现表明，静息 HRV、感知运动效率和整体健康高度相关，支持采用多因素生物心理社会评估来指导设计和实施干预措施，以最大限度地提高 ROTC 学员和其他军人的作战效能。
