“…Following mental (Noto et al, 2005) and emotional (Takai et al, 2004) stress, anxiety scores proved to correlate to sA‐A concentrations. Furthermore, fatigue and tension‐anxiety POMS scales reflected cortisol increases to episodic stress in young college students (Izawa et al, 2007). Because the present data do not confirm a correlation between salivary and POMS values, it is possible to speculate that intense exercise and high competitive situations impose such a high stress on athletes that the parameters studied might highlight different stress‐related mechanisms.…”

The aim of this study was to evaluate the effects of an official Taekwondo competition on the heart rate (HR), salivary α-amylase (sA-A), salivary free cortisol (sC), and Profile of Mood States (POMS) in 10 young male (14±0 years) and six female (13±1 years) athletes. POMS and hormones were measured 15 min before and directly after the competition. During the recovery phase (30 and 90 min), sA-A and sC were also measured. HR measured during the competition was expressed as a percentage of individual's maximal heart rate (%HR(max) ) to evaluate the intensity of exercise. During the competition, athletes spent 65% of the time working at HR>90% of individuals HR(max). A significant increase (P<0.0001) in sA-A (115%) was observed at the end of the match. At 30 min of recovery, sA-A returned to the pre-competition level. The peak sC values were observed at 30 min of recovery (P<0.001), returning to the pre-competition level at 90 min of recovery. A gender difference (P=0.01) emerged only for sC, although a similar trend was observed for female and male athletes. Significantly higher post-match scores emerged for Anger-hostility (pre: 6.1±1.1, post: 11.2±1.9; P=0.03) and Depression-dejection (pre: 4.5±0.5, post: 10.2±1.9; P=0.006), whereas the reverse picture was observed for Vigour-activity (pre: 23.2±1.2, post: 16.3±1.7; P=0.0006). Taekwondo competition results in temporary changes in the stress-related parameters measured in this study. The present findings suggest that this experimental paradigm can represent a useful model for further research on the effects of various stressors (i.e., training and competition) in Taekwondo athletes of different levels (i.e., novice, international).

Even though it has been shown that stress and itch are associated in patients with atopic dermatitis (AD), it remains unclear whether this relationship occurs due to certain coping strategies being activated under stress. Therefore, this study investigates the role of coping as possible mediating factor between stress and itch in 31 patients with AD. Coping and itch were assessed by self-reported measures, while stress was measured both by a validated questionnaire and by a physiological stress marker, the postawakening cortisol. Using a regression and a mediation analysis, this study showed a relationship between perceived stress and itch (corrected R 2 = 0.21), which was fully mediated by negative itch-related cognitions. 62.3% of the variance of itch intensity could be explained by negative itchrelated cognitions. This finding helps to explain the positive effects of cognitive restructuring in the treatment of chronic itch.Key words: atopic dermatitis -coping -itch -postawakening cortisolstress Accepted for publication 28 October 2014Background Atopic dermatitis is a chronically relapsing skin disease characterized by pruritus, lichenification at certain body sites and other atopic diseases in the patient or his family (1). In most of the patients, itch occurs daily (2,3). Stress is proposed to have an impact on the itch intensity (4). Some studies have shown a link between stress and the AD severity (e.g. 5-8), but only one study has specifically shown a relationship between itch and stress in this patient group (9).Coping can be defined as adaptable thoughts and behaviours intended to manage subjective demanding experiences (10). Some authors found that depressive mood/social anxiety, negative itchrelated cognitions and catastrophization are associated with itch in patients with chronic itch (11,12), but whether the effect of stress on itch is mediated by this kind of coping remains unclear thus far. Question addressedThis study investigates whether the relationship between stress and itch in patients with AD is mediated by coping. Experimental designThe data were collected in the context of a greater research project on the effects of stress management in AD (13). Thirty one patients with AD came for two appointments. During the first appointment, patients gave their informed written consent and were instructed on how to collect saliva in the morning on two consecutive days. During the second appointment, perceived stress, coping and itch were assessed. This appointment took place on the second day of saliva collection. VariablesThe criterion variable, 'itch intensity', was determined using a visual analogue scale (0-10) in the context of assessing the severity of AD [SCORAD (14)].The predictor variable, 'perceived stress', was measured by the Recovery-Stress Questionnaire [REST-Q; short version (15)]. The stress items of the REST-Q were aggregated to 'overall strain'. Postawakening cortisol as a physiological marker of chronic stress (e.g. 16,17) was assessed as further predictor. Patients colle...

“…Further, research has demonstrated the effect of certain conditions on levels of different markers. For instance, cortisol levels in saliva are elevated in individuals who have experienced general chronic stress 21,22) . As sIgA decreases with chronic stress, it can be used as an index to objectively evaluate chronic stress 23,24) .…”

We examined the effects of resilience on life stress by measuring subjective and physiological responses. Subjects were 32 college students who reported no remarkable subjective burden at the start of the study (initial period: T1), but some level of stressful burden 3 months later (second period: T2). Resilience levels were evaluated using the Bidimensional Resilience Scale (BRS), which measures innate and acquired resilience. The subjective stress level was assessed with the Stress Response Scale-18 (SRS-18). Saliva was also collected to measure the salivary secretory immunoglobulin A (sIgA) level. BRS was performed at T1, and SRS and saliva collection were administered at both T1 and T2. The subjects were divided into high-and low-resilience groups according to their median scores at T1. Additionally, the high-resilience group was classified as either high-innate resilience (HIR) or high-acquired resilience (HAR), and the low-resilience group as low-innate resilience (LIR) or low-acquired resilience (LAR), respectively, to reveal information in more detail. The depression-anxiety score for the SRS-18 in the low-resilience group was significantly higher than that in the high-resilience group at T2. The sIgA level of the high-resilience group was significantly higher than that of low-resilience group at T2. There were significant negative correlations between innate resilience and depression-anxiety, and total SRS-18 score; and negative correlations among acquired resilience and depression-anxiety, helplessness, total SRS-18 score, and sIgA level, respectively. These results suggested that the stress response in low-innate and acquired resilience differs depending on the length of time elapsed with stress, because low-innate and acquired resilience causes higher susceptibility to "depression-anxiety" as a psychological stress response factor. On the other hand, higher acquired resilience improved immune function in the presence of subjective burden.
