Full textIl est généralement accepté qu'une plus grande capacité de consommation d'O2 musculaire est associée à une meilleure performance aérobie. A l'inverse, une faible capacité de consommation d'O2 musculaire est également associée à une récupération inter-effort réduite/ralentie. A la fin des années 80, le suivi non invasif de l'oxygénation musculaire (mO2), déduite par la mesure de l'hémoglobine ([Hb]) / myoglobine ([Mb]) saturé en oxygène (O2) et de l'[Hb]/[Mb] dépourvu d'O2, a émergé dans de nombreuses études avec l'inclusion de la spectroscopie du proche infrarouge (NIRS). Le fait que la NIRS soit devenue portable rend libre l'évaluation continue de la balance entre apport d'O2 aux muscles en action et consommation musculaire d'O2 des lits capillaires du muscle considéré. Dans cette thèse, nous nous sommes attachés à examiner les considérations méthodologiques de l'utilisation de la NIRS pour évaluer mO2 et consommation d’oxygène musculaire (mVO2) (Etudes 1 et 2). Les études 2, 4 et 5 ont étudié les relations éventuelles qui peuvent exister entre la mO2 et la performance lors d'exercices répétés à haute intensité. Initialement nous avons étudié la reproductibilité et la sensibilité de mO2 post-exercice (Etude 1). Un niveau modéré de reproductibilité, ainsi qu'une indépendance des relevés en fonction de l'intensité d'exercice lors de la récupération sans occlusion ont été constatés. Par contre, lorsque la récupération de la mVO2 était observée, il fut relevé que les mesures étaient, certes modérément reproductibles à l’instar de mO2 post-exercice mais à contrario dépendantes de l'intensité d'exercice. Dans une étude subséquente (Etude 2), nous avons inspecté l'influence des changements de direction (COD) sur la mVO2. Nous avons ainsi observé une plus grande mVO2 avec COD : pour des vitesses similaires absolues de course, les courses en navette sur 20 m étaient associées à de plus grandes mVO2 que lors des courses en ligne droite. Ces résultats suggéraient que mVO2 déjà sensible à l’intensité de l’exercice, l’était aussi à la modalité de course (avec ou sans COD). En second lieu, le rôle de la mO2 sur le paramètre de récupération de force musculaire durant des efforts maximaux répétés a été examiné (Etude 3). Les résultats ont confirmé que la récupération de mO2 peut jouer un rôle modéré dans la production de force maximale. Suite à cette étude, nous avons souhaité évaluer l'influence du type d'entraînement sur la récupération de mVO2 (Etude 4). Ainsi, la comparaison entre entraînement en endurance et entraînement au sprint révèle une meilleure récupération de mVO2 dans le groupe endurance. Cette accélération de la récupération de mVO2 était liée à une meilleure capacité à répéter des sprints. L’entraînement agit donc sur le paramètre de récupération de mV2. En dernière partie, nous avons inspecté dans une étude longitudinale (Etude 5) les effets d’une période d'entraînement aérobie sur la mO2 post-sprints. L'amélioration de la capacité à répéter des sprints a été associée à l'accélération de la mO2 post-sprints, ce qui confirme que la fonction musculaire aérobie pourrait jouer un rôle au niveau dans la récupération métabolique entre les sprints

Full textFrench 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

Full textThe purpose of this study was to investigate the effects of a high intensity interval training program (HIIT) using the upper extremities on peak oxygen uptake (VO2peak), peak heart rate (HRpeak), total time-to-fatigue (TTF), peak power output (PPO), rating of perceived exertion (RPE), and blood lactate concentrations (bLa). Results showed significant (p ≤ 0.05) improvements by the HIIT group in VO2peak, HRpeak, PPO, and TTF when compared to a continuous training (CT) group.
Results of this study suggest that upper extremity HIIT appears to produce greater improvements in several physiological outcome measures when compared to CT and may be an effective way to improve cardiopulmonary fitness. Furthermore, a HIIT program using the upper extremities as little as 2 days per week appears to be a viable way to improve factors that contribute to cardiopulmonary fitness, muscular fitness, and performance, while being an efficient use of time.

Full textContemporary aerobic exercise guidelines comprised of continuous durations and higher intensities have been shown to be effective in the prevention and treatment of risk factors associated with obesity and cardiovascular disease (CVD). However, high-intensity interval training (HIIT) has recently been examined as an advantageous protocol for producing more favorable physiological and psychological benefits in comparison to traditional continuous exercise guidelines. The dual-mode model, which examines the dose response relationship between exercise intensity and affective valence, would suggest that exercise performed well above the ventilatory threshold (VT) in the severe domain should result in negative affective valence.
Numerous investigations have confirmed the reliability of the dual-mode models ability to predict compromised affective valence in the presence of heavy to severe exercise intensities, but only a small amount of research has examined the efficacy of the dual-mode model during HIIT. However, no research to date has combined HIIT with the dual-mode model's efficacy to predict affective valence in target populations challenged by exercise adherence, such as overweight and sedentary individuals. Therefore, the purpose of this study was to examine the dual-mode model's reliability to predict affective valence for overweight and sedentary individuals performing HIIT.
A total of 14 participants (7 male, 7 female) with a mean age of 23 ± 4 (range = 18-33) and mean BMI of 29 ± 3 (range = 25-33) completed the study. Each participant completed a ramp maximal exercise test to determine VT and peak power data, which allowed for specific exercise intensities of delta (DT) to be prescribed for experimental trials. Participants were low to moderate risk. The four experimental conditions were all matched for total work: 1) continuous at 10% DT (Continuous-Heavy - CH), 2) 24 × 30-second intervals at 60% DT (Interval-Severe 30 Second - IS30), 3) 12 × 60-second intervals at 60% DT (Interval-Severe 60 Second - IS60), 4) 6 × 120-second intervals at 60% DT (Interval-Severe 120 Second – IS120). The continuous exercise condition was 20 minutes in duration, whereas all interval exercise conditions were 24 minutes in duration.
Results indicated that in-task perceptual responses defined, as affective valence and perceived enjoyment were overall more favorable during IS30 and IS60 in comparison to CH and IS120. IS30 was the only experimental condition in which affective valence did not decline significantly (p > 0.05). Ratings of perceived enjoyment were greater at all measured time points during IS60 (p < 0.05) in comparison to CH. The findings of this study suggest that HIIT comprised of 30 and or 60 seconds help to facilitate more favorable perceptual responses of affective valence and perceived enjoyment than continuous exercise and intervals of longer than 60 seconds duration.
