Tu es un diététicien du sport certifié ayant travaillé avec des athlètes de haut niveau. Je veux optimiser ma nutrition pour améliorer mes performances sportives. Mon profil : Sport pratiqué : [sport]. Niveau : [niveau : loisir confirmé / compétiteur régional / semi-pro]. Objectif principal : [objectif : améliorer l'endurance / gagner de la force / perdre de la masse grasse en gardant la masse musculaire / récupérer plus vite]. Poids : [poids] kg. Entraînements : [fréquence et durée]. Problèmes actuels : [problèmes : fringales pendant l'effort / manque d'énergie / récupération lente / crampes / autre]. Crée un plan de nutrition sportive complet incluant : 1) Les besoins caloriques et macronutriments calculés pour les jours d'entraînement et de repos (periodization nutritionnelle), 2) Le timing des nutriments : pré-effort (2h avant, 30 min avant), pendant l'effort (pour les séances > 60 min), post-effort (fenêtre anabolique), 3) Les meilleures sources alimentaires de glucides à index glycémique adapté selon le timing, 4) Les protéines : quantité, sources, timing, acides aminés essentiels, leucine threshold, 5) La nutrition pour la compétition et la récupération spéciale post-compétition, 6) La supplémentation éprouvée scientifiquement (créatine, beta-alanine, nitrates, caféine) vs suppléments inutiles, 7) L'hydratation et les électrolytes adaptés à mon sport, 8) Des exemples de repas et collations type pour les jours d'entraînement intense.
Why this prompt works
<p>Periodized nutrition (different intakes on training vs rest days) is the advanced approach that distinguishes elite sports nutrition from simply 'eating healthy'. Adjusting carbohydrates based on training load optimizes both performance and body composition without the negative effects of constant caloric restriction.</p><p>The request about the leucine threshold is an advanced level of precision: leucine is the trigger amino acid for muscle protein synthesis, and consuming a sufficient dose (approximately 2-3g of leucine per meal) is the necessary condition to trigger post-exercise muscle rebuilding. This biochemical precision makes a practical difference.</p><p>The distinction between validated supplements (creatine, beta-alanine, caffeine) and useless or potentially dangerous supplements is particularly useful in a sports nutrition market where many expensive products have no scientific evidence. This critical filter helps athletes not spend unnecessarily and focus on what actually works.</p>
