Prior studies have demonstrated that anxiety and depression explain the increase of adverse cardiovascular events an failure to modulate cardiac activity. This study of the nonlinear heart rate (HR) variability (HRV) behavior can provide additional information concerning the autonomic recovery of HR after exercise. The dynamics of these indices in exercise-mediated situations may reveal other ways to assess HRV recovery after physical effort. We studied nonlinear HRV recovery after submaximal exercise in subjects with higher Hospital Anxiety and Depression Scale (HADS) scores. Sixty-six young adults were recruited, and 50 completed the HADS rating scale to quantify their degree of anxiety and depression for later allocation to a suitable group. After experimental procedures, the final sample involved 20 participants (15 female) who were allocated to the group with low HADS scores (LHADS) and 21 (16 female) to the group with high HADS scores (HHADS). We logged HRV data before and during recovery from submaximal aerobic exercise and analyzed this data using symbolic analysis. Young adults with High HADS scores (HHADS) had a slower recovery of the symbolic analysis of HRV via index 2LV% (two like variations) and 2ULV% (two unlike variations) after aerobic exercise. Participants with higher HADS scores presented delayed nonlinear HRV recovery after submaximal exercise.
先前的研究表明，焦虑和抑郁解释了不良心血管事件的增加和心脏活动调节失败。这项关于非线性心率（HR）变异性（HRV）行为的研究可以提供有关运动后 HR 自主恢复的其他信息。这些指数在运动介导情况下的动态可能揭示其他评估体力活动后 HRV 恢复的方法。我们研究了高 Hospital Anxiety and Depression Scale（HADS）评分受试者在亚最大运动后的非线性 HRV 恢复。招募了 66 名年轻成年人，其中 50 名完成了 HADS 评分量表，以量化他们的焦虑和抑郁程度，以便以后分配到合适的组。经过实验程序，最终样本包括 20 名参与者（15 名女性），他们被分配到低 HADS 评分组（LHADS），21 名（16 名女性）分到高 HADS 评分组（HHADS）。我们记录了亚最大有氧运动前后的 HRV 数据，并使用符号分析对这些数据进行了分析。高 HADS 评分（HHADS）的年轻人在进行有氧运动后，通过指数 2LV%（两个相似变化）和 2ULV%（两个不相似变化），其 HRV 的符号分析恢复较慢。HADS 评分较高的参与者在亚最大运动后表现出延迟的非线性 HRV 恢复。
