description <p> </p><p align="justify"><strong>Objective:</strong> University professors are prone to show physical and psychological diseases related to excessive workload. Such overwork can affect the functioning of the autonomic nervous system, leading to a decrease in heart rate variability (HRV). HRV reflects the continuous fluctuation of the R-R intervals due to sympathetic and parasympathetic actions in the heart and is associated with good physical and psychological health.<strong> </strong>We aimed to evaluate whether psychological stress and anthropometric and clinical variables influence HRV at rest in professors. <strong>Methods:</strong> University professors of both sexes (N=65; 41 men) participated. We collected Anthropometry and Clinical variables, Psychological stress, and HRV parasympathetic parameters (square root mean squares of the differences between RR intervals: RMSSD, number of successive differences between RR intervals, which are &gt; 50 ms: NN50 and high frequency – HF). <strong>Results:</strong>  Four principal components (PCs) represented 68.29% of the data total variation. Principal component 1 (PC1) was called the good cardiac regulation component. PC2 was called the component of reduced stress symptoms. PC3 was named favorable working conditions component. PC4 was denominated component of labor and physiological deregulation. Each HRV parameter was associated with each PC through the use of regression models. The RMSSD was positively associated with PC2. The NN50 was positively associated with PC2 and PC3. HF was positively associated with PC3 and PC4. <strong>Conclusions:</strong> HRV parasympathetic parameters, which represent good physical and mental health, are positively associated with the components of reduced stress symptoms, favorable working conditions, and labor and physiological deregulation.</p><p><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><br /></span></span></strong></p><p><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><br /></span></span></strong></p><p><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><br /></span></span></strong></p><p><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><br /></span></span></strong></p><p><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Objetivo:</span></span></strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"> Professores universitários são propensos a apresentar doenças físicas e psicológicas relacionadas à carga horária excessiva. </span><span style="vertical-align: inherit;">Esse excesso de trabalho pode afetar o funcionamento do sistema nervoso autônomo, levando a uma diminuição da variabilidade da frequência cardíaca (VFC). </span><span style="vertical-align: inherit;">A VFC reflete a flutuação contínua dos intervalos RR devido às ações simpáticas e parassimpáticas no coração e está associada a uma boa saúde física e psicológica. </span></span><strong> </strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Objetivamos avaliar se o estresse psicológico e as variáveis antropométricas e clínicas influenciam a VFC em repouso em professores. </span></span><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Métodos:</span></span></strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Participaram professores universitários de ambos os sexos (N = 65; 41 homens). </span><span style="vertical-align: inherit;">Coletamos variáveis antropométricas e clínicas, estresse psicológico e parâmetros parassimpáticos da VFC (raiz quadrada da média dos quadrados das diferenças entre os intervalos RR: RMSSD, número de diferenças sucessivas entre os intervalos RR, que são&gt; 50 ms: NN50 e alta frequência - HF). </span></span><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Resultados:</span></span></strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">  Quatro componentes principais (PCs) representaram 68,29% da variação total dos dados. </span><span style="vertical-align: inherit;">O componente principal 1 (PC1) foi denominado componente de boa regulação cardíaca. </span><span style="vertical-align: inherit;">PC2 foi chamado de componente de redução dos sintomas de estresse. </span><span style="vertical-align: inherit;">O PC3 foi denominado componente de condições favoráveis de trabalho. </span><span style="vertical-align: inherit;">PC4 foi denominado componente do parto e desregulamentação fisiológica. </span><span style="vertical-align: inherit;">Cada parâmetro de VFC foi associado a cada PC por meio do uso de modelos de regressão. </span><span style="vertical-align: inherit;">O RMSSD foi positivamente associado ao PC2. </span><span style="vertical-align: inherit;">O NN50 foi associado positivamente com PC2 e PC3. </span><span style="vertical-align: inherit;">HF associou-se positivamente com PC3 e PC4. </span></span><strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Conclusões: Os</span></span></strong><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"> parâmetros parassimpáticos da VFC, que representam boa saúde física e mental, estão positivamente associados aos componentes de redução dos sintomas de estresse, condições favoráveis de trabalho e desregulamentação fisiológica e laboral.</span></span></p>
