Повний текст джерелаThe purpose of this study was to investigate psychophysiological relationships in competition in light of psychophysiological models of stress proposed by Frankenhaeuser (1986, 1991) and Henry (1986; Henry & Meehan, 1981). A key notion of these models is that cortisol concentrations are particularly reflective of the hedonic tone of affective state rather then its intensity. To investigate these relationships in the pre-competitive period, three psychological models that emphasize hedonic tone of affective domain in a different manner were chosen: the Mental Health Model (Morgan, 1985), the Directional Model of anxiety (Jones, 1991) and Reversal Theory (Apter, 1989). Eighteen professional soccer players (M age = 24. 6 years, SD = 3. 3), all members of the same team playing in the first division of the French professional league agreed to participate in these studies. Saliva samples were carried out a non-training-day and before three league games. The day of the game, players had to complete three questionnaires. Results of these studies (a) confirmed the existence of differential links between hedonic tone of affective components (e. G. , moods and emotions) and cortisol concentrations during the pre-event phase of the game in professional soccer players; (b) highlighted some psychological constructs that are of interest to investigate psychophysiological relationships. This work attempts to understand and to provide an explanation of stress competition adaptation and purposes, to conclude, different ways in which the results may be useful to optimize performance

Повний текст джерелаMonitoring stress and recovery states is a key issue, especially in high performance sport. An imbalance between stress and recovery can induce fatigue, psychological and physiological exhaustion. Thus, negative consequences on well-being, health and individual and collective performance can be experienced. These consequences are complex as they stem from non-specific environmental, social, psychological and physiological dimensions. These phenomena are subject to important intra-individual and inter-individual variations, which make a diagnosis hard to establish. Based on a several followings of athletes from high performance structures, this research shows the evolution of psychological and physiological variables intervening as a response to stress. From these studies, some predictive variables also showed up in predicting stress and recovery states. Finally, we made evidence of the impact of athletes’ stress and recovery states on emotional states, on the intra and inter-individual levels

Повний текст джерелаSleep disorders in general and nightmares in particular are often associated with psychopathological and physical disorders. They are among the largest and the most frequent complaints reported by patients with PTSD and their links with the severity are now more specified. The overall objectives of this thesis are to shed light on the clinical, psychopathological and psychophysiological aspects of nightmares in the specific context of PTSD, and also to clarify the therapeutic contributions of nightmares centered treatment through a case study. In order to achieve these objectives, a sample of 21 patients suffering from posttraumatic nightmares and hospitalized in a specialized psychotraumatology unit of care were assessed using self-administered questionnaires (IES-R, HAD, PSQI, PSQI-A, NDQ and DES), structured interviews (MINI and the CAPS) and psychophysiological recordings. In parallel, another patient coming from a specialized psychotraumatology center in Paris was carefully monitored in regards of his therapeutic evolution while receiving the Imagery Rehearsal Therapy program on an individual basis. The main results of this research show that the severity of PTSD is strongly and positively associated with the severity of post-traumatic nightmares and that the distress related to nightmares better explains the severity of PTSD that the frequency of nightmares does. The results also confirmed what has been reported in the scientific literature, namely the presence of significant comorbidities. However and in terms of psychophysiological assessments of sleep, no significant results were found in the analysis of polysomnographic recordings, and none of the studied parameters were correlated with the frequency and/or the distress related to nightmares. Finally, the case study was successfully used to evaluate the expected therapeutic benefits of a relatively new psychotherapeutic treatment focusing on nightmares and the results show a significant reduction in the severity of nightmares, accompanied by a reduction in the severity of PTSD and a proportional improvement in sleep quality. In conclusion, the results of this research are consistent with those found in previous studies and underscore the clinical and psychopathological importance nightmares and their involvement in the severity of PTSD

Повний текст джерелаFrench elite athletes specializing in long sprints in track and field face challenges in maintaining optimal performance during international competitions. In this context, the overarching goal of this doctoral research was to adopt a holistic approach to optimize the repetition of high-intensity exercises andenhance athlete recovery during international events. To achieve this, two aspects related to stress were explored: first, the study examined the impact of psychophysiological stress during competition on the regulation of the autonomic and neuroendocrine nervous systems, as well as the evaluation of innovative stress management strategies such as cardiac coherence to improve neuroendocrine regulation and sleep quality during competitions.Additionally, during high-intensity exercises, energy production induces significant metabolic disruptions, such as marked metabolic acidosis (with blood pH below 7 observed after 400 m events), which may hinder performance. To address this, nutritional and hydration strategies, including specific diets and hydration with bicarbonate-rich water, were tested to better regulate metabolic stress.Initial studies revealed psychophysiological disruptions related to competitive stress, with a significant decrease in parasympathetic activity and increased salivary stress biomarkers (cortisol and alpha-amylase). These disruptions, observed during both qualifying phases and finals, correlated withheightened anxiety and reduced recovery capacity (Studies 1 and 2). Interindividual variability highlighted some athletes' heightened sensitivity to competitive stress, emphasizing the need for individualized approaches to better manage these responses.The introduction of coherente breathing as a stress management technique improved autonomic nervous system regulation, reduced inflammation (IL-1β), and enhanced sleep quality, essential for recovery between events. Athletes practicing this technique demonstrated improved hormonal and inflammatory regulation, although no direct impact on competition performance was observed (Study 3).Subsequent studies addressing metabolic stress regulation demonstrated that consuming bicarbonate-rich water combined with an alkalizing diet (as opposed to an acidifying diet) significantly increased blood and urinary pH, improved lactate clearance after repeated exercises, and optimized bufferingcapacity (Studies 4 and 5). These metabolic adjustments enabled athletes to maintain or improve performance, particularly on the third day of high-intensity competition (Studies 5).In conclusion, this research highlights the importance of integrating strategies that combine pre-competitive stress management, particularly through coherent breathing, with tailored nutritional and hydration approaches during international competitions. These strategies promote better regulation ofthe autonomic and neuroendocrine nervous systems, enhance sleep quality, and help manage competition-induced metabolic acidosis. Together, these approaches can improve both performance and recovery for high-level athletes in demanding competitive contexts

Повний текст джерелаThe ability to sense and regulate emotions allows us to have an adapted emotional behavior towards our environment. It is regulated by an interaction of the central nervous system (CNS), including the amygdala and prefrontal cortex (PFC), and the autonomic nervous system (ANS). Yet, our emotional responses can be influenced by a myriad of other factors. They depend for instance on ones' subjective state, and also voluntary conscious intention to control one's emotions. The aim of this thesis is thus to study peripheral and cerebral mechanisms involved in the variability of the emotional response. To do so, we have used five different models susceptibly influencing emotional response: a first model assaying healthy controls in an emotional control task, a second one accounting for their resilience capacity, a third one focused on the impact of neuroticism, a fourth one with acutely stress participants and a last one with post-traumatic stress disorder (PTSD) patients. To better address our objective, we have selected three groups of participants: healthy controls, PTSD patients and fire fighters. We explored responses of the the ANS and the CNS activities using fMRI-based paradigms, specifically tackling the activation of the amygdala and PFC; using an emotional tasks. As hypothesized, our results have shown that voluntary emotional regulation in healthy controls modulates physiological parameters in an emotion-specific manner. For instance the sympathetic system is only activated under those circumstance when processing fearful clips

Повний текст джерелаThis work had two main objectives which were to carry out the monitoring of biopsychological markers, first a) during a season with elite rugby players and b) within two games of a basketball competition. Specifically, we followed up, in a first study, a professional rugby team over a season evaluating whether the status of the competing athlete had an impact on changes in the markers under study. We found significant decreases in markers such as testosterone, the ratio T/C and DHEA-S during the season. These results would suggest that fatigue had increased for the entire group during the season. However, when investigating the role of status, we have only found decreases in testosterone and DHEA-S as well as some states of negative mood (depression, anger) in the group of holders. In the same vein, we have encountered opposite results for the biopsychological markers in the group of players who had been almost never used over the season. Consequently, we can suggest that the status has an important role to account for biopsychological responses of players regardless of the period of the season. In a second study (b), we chose to monitor biopsychological markers of the players in two games of an official competition of basketball championship. Our goal was to study the development of biopsychological markers in athletes used to compete for official meetings and to test if a habituation process could take place among players in the precompetitive phase. The results have not shown clear signs of habituation to precompetitive stress between the two games. We have not shown any significant change in the biopsychological values (i.e., cortisol and anxiety state markers)regardless of the game played. Consequently, the hypothesized habituation process to the competition may have already occurred in the past and results may just be the result of it. In conclusion, the relative stability of biopsychological markers could show a form of habituation to anticipatory stress in team sport players compared to athletes in individual sports

Повний текст джерелаAlthough most people encounter at least one traumatic event over their lifetime, not all of them will develop post-traumatic stress disorder (PTSD). Lifetime prevalence of full-blown PTSD, known as an anxiety disorder, is in fact around 10%. In addition to accidents, aggression, grief, rape, fires, traumatic events can be caused by natural (flooding, earthquake…) or man-made stressors (war, terrorism…). With the contemporary rise in traumatic sources the World Health Organization recent reports describe PTSD as an increasing global health issue, due to its high frequency, severity, comorbidity and cost. A body of research has thus started investigating various aspects of PTSD concerned with intrusive thoughts, hypervigilance, emotional deficits, cognitive disturbances and memory issues. Similarly to other mental health problems, much remains unknown about PTSD, and similarly to other anxiety disorders it is marked by excessive fear. It comes as no surprise that the most prevalent hypothesis in PTSD is that of a fear-processing deficit. Conceptualizing PTSD as a fear disorder can be phenomenologically quite narrow. It has been nonetheless pragmatic in allowing thorough translational research from animal to bench-side and clinical studies. Most studies have suggested that central and peripheral impairments in PTSD revolve around altered neural fear processing network. These alterations involve mechanisms implicated in fear conditioning, as well as emotional and attentional processing, all of which are altered in PTSD
