Changes in biophysiological markers related to perceived burnout and self-comfort were tested in this study. Forty-two student-athletes from middle and high school grades were evaluated for burnout, salivary cortisol levels, measures of arousal-related physiological markers (i.e., blood volume pulse; BVP), galvanic skin response (GSR), and respiratory rate, and self-comfort variables during the last two weeks of the season. Using self-comfort theory as its conceptual framework, we examined burnout through a conceptual model in which feeling of discomfort with the self was related to biophysiological markers affecting perceived burnout. The proposed model was tested by using a partial least squares structural equation modeling (PLS-SEM). The main findings indicate that increased self-discomfort is significantly (p < .001) associated with increased salivary cortisol (β = - 0.189) along with a significant (p = .050) decrease in GSR (β = - 0.259). Increased salivary cortisol is significantly (p < .001) associated with increased burnout (β = 0.242). The findings partially support the model and encourage further effort to capture the burnout syndrome through the integration of biological and psychological markers.
本研究旨在测试与感知倦怠和自我舒适相关的生物生理标志物的变化。在赛季的最后两周，对来自中学和高中的 42 名运动员进行了倦怠、唾液皮质醇水平、与觉醒相关的生理标志物（即，血流脉冲；BVP）、皮肤电反应（GSR）和呼吸率以及自我舒适变量的评估。本研究以自我舒适理论为概念框架，通过一个概念模型来考察倦怠，其中自我不适的感觉与影响感知倦怠的生物生理标志物有关。使用偏最小二乘结构方程建模（PLS-SEM）来检验所提出的模型。主要发现表明，自我不适的增加与唾液皮质醇的增加显著相关（p <.001，β = - 0.189），同时 GSR 的显著下降（p =.050，β = - 0.259）。唾液皮质醇的增加与倦怠的增加显著相关（p <.001，β = 0.242）。研究结果部分支持该模型，并鼓励通过整合生物和心理标志物进一步努力捕捉倦怠综合征。
