“…As HRV is associated with impaired sleep (Tobaldini et al, 2013;Uçar et al, 2018) and with cardiac (Haensel et al, 2008) and metabolic problems (Stuckey et al, 2014), we were expecting to observe a (Sato et al, 2011). In the present study, significant correlations were found between HRV parameters and sleep parameters and cortisol measured after wakeup in the morning.…”

“…When the participants brought their saliva samples to the laboratory, they were kept resting for at least an hour. ECG record of the rested participants was taken for 5 min in supine positions (Uçar et al, 2018). The participants were not allowed to speak, or close their eyes longer than blinking (they were told not the close their eyes as if they are sleeping but stare at the ceiling).…”

“…In fact, significant correlations have been found between the end product of HPA axis, that is cortisol secretion, and body mass index (Joseph et al, 2017). Furthermore, cortisol awakening response (CAR), a measure of the activity of HPA axis as assessed by salivary cortisol levels immediately following wake up in the morning, has also recently been associated with sleep parameters (Devine &Wolf, 2016;Uçar, Özgöçer, & Yildiz, 2018), cardio-metabolic health (Kastaun et al, 2014), obesity (Incollingo Rodriguez et al, 2015). ANS activity, measured non-invasively by heart rate variability (HRV), that is beat-to-beat variation in heart rate, has been associated with sleep parameters (Tobaldini et al, 2013;Uçar et al, 2018), cardiac (Haensel, Mills, Nelesen, Ziegler, & Dimsdale, 2008) and metabolic problems (Stuckey et al, 2014).…”

However, it is currently not known whether the detrimental effects of late night eating of high calorie foodstuffs is manifested by sleep impairment, or disruption of stress axes, namely HPA and ANS, or both.…”

Aim of the current study was to assess the effects of the digestibility of late-night high calorie meal on sleep and the activities of the hypothalamo-pituitary-adrenal (HPA) and autonomous nervous system (ANS) in healthy young males. For that purpose, effects of an easily digestible meal (starch + sugar-rich meal, SSR, i.e., dessert) or a slowly digestible meal (protein + fat-rich, PFR, i.e. kebab) were investigated in a crossover design in 16 participants (20-26 year old). They did not eat anything after 07:00 PM on Day 0; had an SSR meal on Day 1 and a PFR meal on Day 2 at 10:00 PM. HPA and ANS activities were measured by cortisol awakening response (CAR) and heart rate variability (HRV), respectively. The participants provided salivary samples for CAR; had a 5-min continuous electrocardiogram recording for HRV; and filled in sleep questionnaires. Late-night eating of SSR and PFR diets increased the area under the curve of CAR (p < 0.05) but did not affect HRV parameters (p > 0.05). PFR meal significantly disturbed sleep (p < 0.05). The data suggests that increased activity of HPA, but not ANS, might be involved in pathophysiology of late-night eating and that this might be due to disturbed sleep if slowly-digestible meal is consumed.

“…Of interest, single bouts of exercise are unlikely to change the CAR; two studies did not provide support for changes in CAR when exercise was carried out the day prior to the CAR measurement (Garde et al, 2009;Uçar, Özgöçer, & Yildiz, 2018). However, single bouts of exercise might be effective in reducing overall cortisol levels; low-level physical exercise reduced cortisol levels in young adults on the Autistic Spectrum, who are considered to experience severe stress and anxiety (Hillier, Murphy, & Ferrara, 2011).…”

The effect of acute exercise on the cortisol awakening response

et al. 2023

The effects of acute exercise on the cortisol awakening response (CAR), characterized by the rapid increase in cortisol concentrations within the 30-45 min following sleep offset has yet to be fully elucidated. Thus, our study investigated the effects of late-evening acute exercise on the CAR the following morning. We hypothesized that exercise would have a significant effect on the CAR the following morning. Twelve participants (mean (SD): age = 23 (4) years; mass = 76.8 (8.7) kg; height = 175.6 (5.0) cm; V ̇O2max = 48.9 (7.5) ml.kg−1.min−1) reported to the laboratory in the evening (1800 h) on two occasions and were randomly assigned to either exercise for one hour (70-75% of maximal power output) or rest condition. Blood and saliva samples were assayed for cortisol. Mixed-effects models determined the effect of exercise on the cortisol response postwaking in both blood and saliva. Participants demonstrated an average exercise-induced increase in circulating cortisol of 477.3%, with actual mean (SD) heart rate relative to maximum of 87.04% (6.14%). Model results demonstrated a negative effect for exercise condition when modeling the serum and salivary cortisol responses to awakening via a quadratic growth model (serum, βCondition = − 42.26 [95% CI − 64.52 to − 20.01], p < 0.001; saliva, βCondition = − 11.55 [95% CI − 15.52 to − 7.57], p < 0.001). These results suggest that cortisol concentrations in saliva and blood are significantly lower the morning following a prior evening exercise session. Therefore, the CAR may serve as a useful biomarker to monitor responses to exercise training, although the underlying mechanism for these decreases in the CAR should be investigated further.
