“…Reduced HRV has been observed in response to acute psychological stress (Filaire et al, 2010;Nater et al, 2006). Similarly, the present results showed decreased HF-HRV in the stress compared to the control block, reflecting reduced parasympathetic activity under stress (O'Donnell, Landolt, Hazi, Dragano, & Wright, 2015;Thayer et al, 2012). This pattern of parasympathetic inhibition and sympathetic activation under stress is consistent with the NVI model (Thayer et al, 2012).…”

The current study investigated the influence of acute psychological stress on selective attention processes. After an acute stressor or a control condition, 20 participants performed an arrow‐based version of the Eriksen flanker task, while ERPs (N1, N2, P3), reaction times, accuracy, subjective stress, and electrocardiogram signal were measured. Results showed elevated self‐report stress, negative affect, state anxiety, heart rate, and reduced high‐frequency heart rate variability in the stress block than in the control block, indicating that the flanker task was performed in a stressful situation. In the flanker task, faster response and larger flanker effect of accuracy were observed for the stress block relative to the control block, indicating increased arousal level and improved conflict detection under stress. Event‐related potentials locked to target stimuli in the flanker task revealed that (a) frontal N1 was amplified in the stress block than in the control block, indicating elevated vigilance level under stress; (b) frontal N2 was increased in the stress block than in the control block for both congruent and incongruent trials, indicating more intensive attention control under stress; and (c) Increased P3 in the stress block than in the control block may reflect more allocation of neural resources as a consequence of improved attentional control under stress. These findings suggest that acute psychological stress increases general alertness and promotes attentional control in selective attention processes.

“…Researchers studied salivary cortisol (11,28,30–34,37 –40 ,42 –47,49–54,56–68,70,71) and/or salivary α-amylase response to stress (11,29,32,33,35,36,40–42 ,44 ,48,49,52,53,55,59 ,61,63,66,69–72) for their association with CV/CM items. A substantial number of these studies showed significant correlations between salivary cortisol and/or salivary α-amylase and clinical/subclinical CV/CMR indicators (28,29,31,32,36,37,44,50,55).…”

Salivary cortisol and α-amylase: subclinical indicators of stress as cardiometabolic risk

Currently, the potential for cardiovascular (CV) stress-induced risk is primarily based on the theoretical (obvious) side effects of stress on the CV system. Salivary cortisol and α-amylase, produced respectively by the hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic-adrenomedullary (SAM) system during stress response, are still not included in the routine evaluation of CV risk and require additional and definitive validation. Therefore, this article overviews studies published between 2010 and 2015, in which salivary cortisol and α-amylase were measured as stress biomarkers to examine their associations with CV/CMR (cardiometabolic risk) clinical and subclinical indicators. A comprehensive search of PubMed, Web of Science and Scopus electronic databases was performed, and 54 key articles related to the use of salivary cortisol and α-amylase as subclinical indicators of stress and CV/CMR factors, including studies that emphasized methodological biases that could influence the accuracy of study outcomes, were ultimately identified. Overall, the biological impact of stress measured by salivary cortisol and α-amylase was associated with CV/CMR factors. Results supported the use of salivary cortisol and α-amylase as potential diagnostic tools for detecting stress-induced cardiac diseases and especially to describe the mechanisms by which stress potentially contributes to the pathogenesis and outcomes of CV diseases.

“…Moreover, it can be seen as a first step to explaining why different studies came to diverging conclusions concerning the impact of autonomy on physiological stress (O'Donnell et al, 2015;Reeve and Tseng, 2011). Additionally, our results have a high practical relevance, as they suggest that the implicit autonomy disposition -as a moderator of the link between autonomy support and physiological stress -is an important factor to consider when designing health-promoting school environments.…”

“…on this link (Reeve and Tseng, 2011;O'Donnell et al, 2015) have revealed inconsistencies and it is not clear whether autonomy is associated with an increase or a decrease in physiological stress. In a school context, Reeve and Tseng (2011) were able to identify effects of teachers' autonomy support on students' cortisol levels.…”

a b s t r a c tThe empirical evidence for the relationship between autonomy-supportive environments and physiological stress is inconsistent. Whereas some studies report a decrease in stress in autonomy-supportive environments, other studies show a negative effect of autonomy on physiological stress. As previous research has not considered individual differences within this relationship, the present research aims to close this empirical gap by proposing that an implicit autonomy disposition, which is defined as a dispositional preference for self-determination, serves as a moderator. In an experiment, we tested whether the autonomy disposition moderates the effect of different teaching styles (controlling, autonomy-supportive, and neutral) on the acute physiological stress response (salivary alpha-amylase) in adolescents (N = 69). The study revealed that participants with a high implicit autonomy disposition displayed lower salivary alpha-amylase responses when exposed to autonomy-supportive vignettes compared to when they were exposed to controlling or neutral teaching styles. The opposite pattern was found in students with a low implicit autonomy disposition. The results illustrate that experimentally induced variations in autonomy support lead to different physiological stress responses, depending on individual differences in the implicit autonomy disposition.
