Natural Hydration Protocols in Combat Sports Athletes: A Clinical Framework for Pre-Competition Management

This bilingual clinical technical report (English/Spanish) presents the TFL Natural Hydration Framework, a three-phase, pharmacology-free protocol for pre-competition hydration management in combat sports athletes. The framework covers gradual weight management (Phase A), point-of-care assessment at weigh-in (Phase B), and a structured post-weigh-in rehydration sequence (Phase C) including a glucose-free electrolyte solution, protein introduction at 30 minutes, and subsequent carbohydrate loading. A mechanistic explanation of the 150% fluid replacement target is provided with supporting data from peer-reviewed literature. Special clinical considerations for youth athletes (ages 10–17) are addressed in a dedicated section, drawing on the author's published work (Maccio Pereira, Journal of Combat Sports Medicine, 2026). A homemade oral rehydration solution recipe and commercial product warning are included. Intended for ringside physicians, team medical staff, and combat sports regulatory organizations.
