Résumé : The link between stress and heart rate variability (HRV) has been extensively studied, considering this biomarker an objective measure of stress responses because it reflects autonomic nervous system characteristics. Indeed, HRV indexes the balance between the sympathetic nervous system and the parasympathetic nervous system, which are both impacted in stress responses. Due to the neurobiological structures involved in HRV, it has often been associated with emotion regulation, a component of a broader emotion management concept: emotional competencies. Some researchers have proposed a protective role of emotional competencies on physiological reactivity to stress, such as cortisol secretion, but HRV has received much less attention despite its utility to assess stress responses. Thus, the aim of this study was to explore the links between HRV and emotional competencies under stress conditions. Sixty-eight participants fulfilled the criteria of the Profile of Emotional Competence, and HRV was measured during 5 minutes in resting, reactivity to, and recovery from an interpersonal stressor induced in a laboratory. Contrary to our expectations, we did not find any associations between HRV measures and trait emotional competencies scores. Interestingly, we highlighted that subjects with higher trait emotional competencies scores returned to the same HRV level as in the resting measure, but those with lower scores continued to exhibit a reduced HRV. In conclusion, our study is one of the first to evidence that trait emotional competencies might have a positive influence on the capacity and the rapidity of the autonomic nervous system to recover from a stressor.
