Повний текст джерелаHigh-intensity interval training has been shown to be more effective than moderate intensity continuous training for improving maximal oxygen uptake (VO2max) and metabolic profile in patients with coronary heart disease (CHD). However, no evidence supports the prescription of one specific protocol of high intensity interval exercise (HIIE) in this population. We have compared the acute cardiopulmonary responses to four different sessions of HIIE in order to identify the most optimal one in CHD patients. In random fashion, subjects performed the different HIIE sessions, all with exercise phases at 100% of maximal aerobic power (MAP), but which varied in interval duration (15 s or 60 s) and type of recovery (0% of MAP or 50% of MAP). Each protocol lasted 35 minutes or until exhaustion. When considering perceived exertion, patient comfort and time spent above 80% of VO2max, we found that repeated bouts of 15s at 100% of MAP interspersed by 15s phases of passive recovery was the optimal HIIE session for these coronary patients. Then, we compared the physiological responses to the optimized HIIE versus a moderate intensity continuous training (MICE) protocol of similar energy expenditure in coronary patients. When considering physiological responses, safety (no elevation of Troponin T) and perceived exertion, the HIIE protocol appeared to be well tolerated and more efficient in this group of stable coronary patients. Finally, a single bout of HIIE did not induce deleterious effects on the endothelium, as demonstrated by endothelial microparticules analyses. We conclude that high-intensity interval exercise is a promising mode of training for patients with stable CHD that should also be further investigated in cardiac patients, particularly with exercise-induced ischemia

Повний текст джерелаEvolution of performances and fatigue processes during intermittent cycling sprints (6-8 s)is analyzed through effects of time of day, gender, and recovery period repartition. Fatigue and recovery processes of anaerobic maximal power output are poorly dependant on biologic rhythms and gender. However, women exhibit greater fatigability than men within the same srpint (P<0,005). The repartition of recovery periods (same total duration : constant, increasing, or decreasing duration)modifies the time of fatigue development (P<0. 05), but do not affect overall performance during series. Owing to neuromuscular activity and inter-muscle coordiantion, the decline in performances during sprints is attributable to fatigue that is peripheral and central in origin

Повний текст джерелаEndurance training is currently used in chronical diseases to improved aerobic performance and quality of life of these patients. Continuous endurance training and interval training are the both modalities used in rehabilitation. In a first part, we compared the effects of these two trainings modalities from systemic to cellular adaptations. Sixteen subjects performed the both trainings modalities which are characterized by same energy expenditure and training duration. Aerobic performance was improved by both trainings modalities throughout different adaptations. Interval training improved central adaptations (cardiac output) and peripheral adaptations (capillary density and mitochondrial function) whereas continuous training enhanced capillary density. In the second part, we compared sedentary subjects and endurance athletes to determine the effect of endurance training at high intensity on mitochondrial function. Athletes presented quantitative and qualitative modifications toward a greater capacity to oxidize carbohydrate. Our results improve the knowledge about the endurance training induced adaptation. They favorite the endurance training prescriptions for chronical disease patients and allow to choose the training modality in function of patient’s disease. Finally, it will improve quality of life of chronical disease patients

Повний текст джерелаThis thesis falls within the general framework of the energetic physiology, and includes three studies, ranging from global exploration of the humans in motion (field tests with athletes of the French Cycling Team, laboratory exploration during exercise on trained cyclists) to studies of muscle metabolism by techniques of cellular and molecular investigations in active subjects. This work has focused on high-intensity exercise generating high levels of muscle fatigue and the resulting adaptive cardiorespiratory and muscular responses. Supplementation of sodium bicarbonate against placebo was used to study the precise role of the accumulation of protons during sprint cycling sessions. Through this work, we have shown that, if an induced alkalosis did not systematically improve sprint cycling performances, a significant disruption of the pH led to changes in oxygen transport during exercise, in mitochondrial function after 24h of recovery, but also in the expression of some proteins involved in pH regulation (i. E. , lactate/proton co-transporter (MCT1) its chaperone protein CD147, and the sodium/proton exchanger (NHE1)). These changes were related to a reduction of the oxidative stress induced by alkalosis, suggesting a harmful role of the carbonylation in these protein expressions. These results provide a new perspective on the role played by acidosis in the regulatory mechanisms at physiological, cellular and molecular levels in humans

Повний текст джерелаThe functional adaptations of various skeletal muscles, were investigated in response to a high-intensity exercise training, i. E. Jumping. The mechanical analysis reveals an increase in resistance and passive stiffness of pennate Extensor Digitorum Longus (EDL) and Rectus Femoris (RF) muscles after training, in addition to a general increase induced by age. This increase in passive mechanical qualities could be linked to an increase in collagen concentration of muscles. .

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 джерелаEndurance exercise is essential for different reasons in athlete and also in aging and pathological people. Two training modalities were found: high intensity interval training (HIIT) and moderate intensity aerobic training (MOD). However, the specific outcomes of these modalities on physical performance and cerebral and muscular plasticity are controversial because many exercise protocols exist. The 1st study explore the impact of these 2 training on endurance and functional capacity and also on muscular and cerebral molecular modifications throughout 8 weeks in healthy rats. HIIT and MOD programs are work-matched and training intensity are determined thanks to the lactate threshold. Our results show a superior and fast effect on endurance capacity after HIIT compared to MOD. Hippocampal plasticity is stimulated only after HIIT and muscular modifications appear to be specific to each modality. A great interest of HIIT is found in stroke patients for whom evidence of endurance modalities efficiency is still missing. A previous study has shown a beneficial effect of HIIT in the acute phase of stroke despite incomplete sensorimotor recuperation. Hence, the interest to deepen in second part of this manuscript the impact of two HIIT modalities (short and long) in recovery optimisation. Our results show that 2 HIIT strongly improve endurance performance and strength of injured paw with a fast effect for long HIIT. The 2 modalities seem to induce cerebral angiogenesis. However, these 2 training do not increase sensorimotor and cognitive functions. In perspective, it appears necessary to develop muscular and cerebral outcomes induced by these 2 HIIT modalities

Повний текст джерелаAfter being contraindicated, physical activity take an increasingly important place in the management of multiple sclerosis (MS). The training at mild to moderate intensity is widely documented, contrary to the high intensity training. This work has focused on the effects of high intensity interval training combined with resistance training during 12 weeks in 26 MS patients. Our results show that peak oxygen consumption, maximum tolerated power, isokinetic muscle strength in both quadriceps and hamstrings and quality of life are improved. Women show more important and more numerous improvements than men, however, the disability level does not seem to limit improvements. Our work has demonstrated that high intensity interval training combined with resistance training is well tolerated and allows physical capacities and quality of life improvements

Повний текст джерелаHigh blood pressure is a common disease with many cardiovascular complications. Inactivity is also an important cardiovascular risk factor, and the regular practice of physical activity (PA) decreases very significantly this risk, more than the single improvement of blood pressure (BP). Therefore, PA is recommended for its contribution on the management of hypertension. The “acute” BP fall following a bout of exercise contributes to the “chronic” antihypertensive effect of physical training, by inducing both functional and structural adaptations (BP regulation systems and components of arterial wall, respectively). Face to the many modalities of PA (aerobic, strength, continuous or intermittent mode, outdoor, indoor or in swimming-pool) and to the desires and availabilities of the patient, we aimed to assess, in hypertensive individuals, the effect of new modes (high-intensity intermittent exercise (HIIE), cycling in immersed condition) using preferably ambulatory BP monitoring measures. Thereby, our research identified, through a meta-analysis and 3 clinical studies, the following results:A- regarding PA characteristics : 1- a BP decrease following one bout of HIIE, 2-week HIIE training (thrice a week) and 9-month HIIE training (twice a week) in a combined lifestyle program;2- an additional BP improvement in up-to-the chest immersed condition; 3- an improvement in arterial stiffness (pulse wave velocity, PWV);B- regarding patient’s characteristics: favorable moderators such as a resting BP ≥135/85 mm Hg, or the association of diet intervention. These results should contribute to improve prescription of PA in hypertensive individuals
