Marqueurs biochimiques et psychologiques de la fatigue chez les athlètes de MMA

This study investigates the physiological and psychological responses of mixed martial arts (MMA) athletes to a structured high-intensity strength and conditioning training program. The primary focus is on monitoring temporal changes in key biochemical markers (e.g., cortisol, catecholamines, inflammatory cytokines) and psychological factors (e.g., mood profiles, stress, recovery states) to understand the balance between training-induced fatigue and recovery. The study is conducted over three weeks, during which athletes follow a standardized training regimen comprising strength, endurance, and technical drills. Training intensity and volume are carefully managed, with no changes introduced during the observation period to ensure consistent data collection. Baseline measurements are taken 48 hours after a rest period to eliminate the effects of prior workouts. Key Features: Biochemical Analysis: Blood samples are collected at four time points (pre-study, and after each training week) under standardized conditions, including morning fasting to minimize variability due to circadian rhythms. Markers such as cortisol, catecholamines, hs-CRP, myoglobin, and urea are analyzed using validated ELISA protocols and biochemical kits. Psychological Assessment: The RESTQ-76 SPORT (Recovery-Stress Questionnaire for Athletes) and POMS (Profile of Mood States) questionnaires are administered before each blood sample collection to evaluate athletes' stress-recovery balance and mood states. Training Protocol: Athletes train six days a week for approximately 15 hours total per week. Training includes a mix of circuit training, weightlifting, technique drills, and sparring, designed to mimic typical MMA preparation. Study Goals: This study aims to determine the effects of a high-intensity training regimen on the interaction between physiological stress markers and psychological states. It seeks to provide insights into early indicators of overtraining and inform personalized approaches to athlete training that optimize performance while reducing injury risk. By integrating biochemical and psychological data, this research highlights the need for a holistic approach to training management in MMA athletes, with implications for broader sports science and athletic performance enhancement.
