“…The experimental order of the sessions was counterbalanced. The two sessions were separated by 1 week, to keep learning effects to a minimum, and took place at the same time of the day, given this parameter may influence HRV (van Eekelen et al, 2004) and performance (Folkard, 1990; Laborde et al, 2018a). Participants were either taking part in Experiment 1 or Experiment 2, they could not participate to both.…”

This research aims to investigate whether slow-paced breathing (SPB) improves adaptation to psychological stress, and specifically inhibition, when it is performed before or after physical exertion (PE). According to the resonance model, SPB is expected to increase cardiac vagal activity (CVA). Further, according to the neurovisceral integration model, CVA is positively linked to executive cognitive performance, and would thus play a role in the adaptation to psychological stress. We hypothesized that SPB, in comparison to a control condition, will induce a better adaptation to psychological stress, measured via better inhibitory performance. Two within-subject experiments were conducted with athletes: in the first experiment ( N = 60) SPB (or control – neutral TV documentary) was realized before PE (“relax before PE”), and in the second experiment ( N = 60) SPB (or the watching TV control) was realized after PE (“relax after PE”). PE consisted of 5 min Burpees, a physical exercise involving the whole body. In both experiments the adaptation to psychological stress was investigated with a Stroop task, a measure of inhibition, which followed PE. Perceived stress increased during PE (partial η 2 = 0.63) and during the Stroop task (partial η 2 = 0.08), and decreased during relaxation (partial η 2 = 0.15), however, no effect of condition was found. At the physiological level PE significantly increased HR, RF, and decreased CVA [operationalized in this research via the root mean square of successive differences (RMSSD)] in both experiments. Further, the number of errors in the incongruent category (Stroop interference accuracy) was found to be lower in the SPB condition in comparison to the control condition, however, these results were not mediated by RMSSD. Additionally, the Stroop interference [reaction times (RTs)] was found to be lower overall in “relax before PE,” however, no effect was found regarding SPB and Stroop interference (RTs). Overall, our results suggest that SPB realized before or after PE has a positive effect regarding adaptation to psychological stress and specifically inhibition, however, the underlying mechanisms require further investigation.

“…This mid‐sleep variable correlates with DLMO ( r = 0.4–0.8), a gold standard circadian marker (Burgess et al., ; Kantermann, Sung, & Burgess, ; Kitamura et al., ). Other questionnaire‐based approaches comprise an assessment of diurnal preference (Adan & Almirall, ; Horne & Ostberg, ; Laborde et al., ); a comprehensive overview of the existing instruments can be found here (Levandovski, Sasso, & Hidalgo, ; Putilov, ). Chronotype is sometimes used as a proxy for circadian disruption (e.g., Knutson & von Schantz, ; Merikanto et al., ), with the assumption that later types would be more misaligned due to daytime social commitments and activities than earlier types.…”

Circadian disruption: What do we actually mean?

The circadian system regulates physiology and behavior. Acute challenges to the system, such as those experienced when traveling across time zones, will eventually result in re‐synchronization to local environmental time cues, but this re‐synchronization is oftentimes accompanied by adverse short‐term consequences. When such challenges are experienced chronically, adaptation may not be achieved, as for example in the case of rotating night shift workers. The transient and chronic disturbance of the circadian system is most frequently referred to as “circadian disruption”, but many other terms have been proposed and used to refer to similar situations. It is now beyond doubt that the circadian system contributes to health and disease, emphasizing the need for clear terminology when describing challenges to the circadian system and their consequences. The goal of this review is to provide an overview of the terms used to describe disruption of the circadian system, discuss proposed quantifications of disruption in experimental and observational settings with a focus on human research, and highlight limitations and challenges of currently available tools. For circadian research to advance as a translational science, clear, operationalizable, and scalable quantifications of circadian disruption are key, as they will enable improved assessment and reproducibility of results, ideally ranging from mechanistic settings, including animal research, to large‐scale randomized clinical trials.

“…The following MESH terms were used: (bipolar dis* OR mani* OR manic‐depress* OR hypomani* OR affective psychosis) AND (chronotype* OR eveningness OR morningness OR circadian preference* OR biological rhythm* OR circadian rhythm*). The searches were then repeated with the term chronotype* (or equivalents) being replaced by the names of specific self‐rated or observer‐rated scales such as: Horne and Ostberg Morningness–Eveningness Questionnaires (MEQ), 21 Brief or Revised MEQ, 30 Composite Scale of Morningness (CSM), 22 Munich Chronotype Questionnaire (MCTQ), 23 Social Metric Rhythm (SMR), 31 Circadian Type Inventory (CTI), 24,25 Sleep, Circadian Rhythms, and Mood questionnaire (SCRAM), 32 Morningness–Eveningness‐Stability‐Scale improved (MESSi), 33 Caen Chronotype Questionnaire (CCQ), 34 Circadian Energy Scale (CIRENS), 35 Mood Rhythm Instrument (MRI) 36 and Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) 26 .

Chronotypes and circadian rest–activity rhythms in bipolar disorders: a meta‐analysis of self‐ and observer rating scales

Objective Chronobiological models postulate that abnormalities in circadian rest/activity rhythms (CRAR) are core phenomena of bipolar disorders (BDs). We undertook a meta‐analysis of published studies to determine whether self‐ or observer ratings of CRAR differentiate BD cases from comparators (typically healthy controls [HCs]). Method We undertook systematic searches of four databases to identify studies for inclusion in random effects meta‐analyses and meta‐regression analyses. Effect sizes (ES) for pooled analyses of self‐ and observer ratings were expressed as standardized mean differences with 95% confidence intervals (CIs). Results The 30 studies meeting eligibility criteria included 2840 cases and 3573 controls. Compared with HC, BD cases showed greater eveningness (ES: 0.33; 95% CI: 0.12–0.54), lower flexibility of rhythms (ES: 0.36; 95% CI: 0.06–0.67), lower amplitude of rhythms (ES: 0.55; 95% CI: 0.39–0.70) and more disturbances across a range of CRAR (ES of 0.78–1.12 for general and social activities, sleep and eating patterns). Between study heterogeneity was high (I2 > 70%) and evidence indicated a potential publication bias for studies using the Biological Rhythms Interview of Assessment in Neuropsychiatry. Meta‐regression analyses suggested significantly larger ES were observed in studies using observer ratings or including BD cases with higher levels of depressive symptoms. Conclusion This meta‐analysis demonstrates that BD is associated with higher levels of self‐ or observer‐rated CRAR disturbances compared with controls. However, further studies should examine the respective performance of individual instruments when used alone or in combination, to clarify their applicability and utility in clinical practice.
