- Identify Selected Track & Bioenergetic Profile: State your chosen track (Track 1 Clinical, Track 2 Community, or Track 3 Performance), client initials, and primary energy systems recruited during their activity.
Indique la ruta seleccionada, iniciales del cliente y los sistemas energéticos principales reclutados. - Clinical Framing Protocol (Pattern / Rule / Solve) Analysis (Pattern / Rule / Solve): Detail the metabolic bottleneck or crossover shift (Pattern), apply federal DGA carbohydrate intake ranges in g/kg/day (Rule), and calculate an individualized acute post-workout recovery target in grams (Solve).
Detalle el cuello de botella metabólico (Patrón), aplique las pautas DGA de carbohidratos en g/kg/día (Regla) y calcule la meta de recuperación post-ejercicio en gramos (Solución). - Bilingual Client Takeaway Card: Provide a concise 2-sentence explanation of the fueling strategy in both English and Spanish so your client understands why carbohydrate timing protects performance and recovery.
Incluya una explicación concisa de 2 oraciones en inglés y español para educar al cliente sobre la importancia del glucógeno y la recuperación.
Peer Engagement Requirement / Requisito de Interacción (Due Sunday by 11:59 PM MST)
Respond to at least ONE (1) classmate who selected a different track than yours (Minimum 1 Reply Required). Evaluate their carbohydrate calculations (g/kg/day and recovery targets), compare their substrate crossover demands, and discuss how nutritional timing differs between clinical, occupational, and athletic settings.
Responda al menos a UN (1) compañero que haya elegido una ruta diferente a la suya (mínimo 1 respuesta). Evalúe sus cálculos de carbohidratos y compare la demanda de sustratos entre el ámbito clínico, ocupacional y deportivo.
10/10 High-Fidelity Student Exemplar / Ejemplo de Entrega (10/10)
Target Cognitive Level: Track 3 (Athletic Performance) Example- Track & Energy Systems: Track 3 Sports Performance. A.V. relies on Fast Glycolysis for repeated 10-to-30 second high-intensity sprints, interspersed with Oxidative Phosphorylation during recovery intervals to clear lactate and resynthesize phosphocreatine (PCr).
Ruta 3 Rendimiento Deportivo. Utiliza glucólisis rápida para sprints repetidos y fosforilación oxidativa durante pausas para resintetizar fosfocreatina. - Clinical Framing Protocol (Pattern / Rule / Solve) Audit:
Pattern (Substrate Crossover & Depletion): High-intensity soccer forces the metabolic crossover entirely to carbohydrate oxidation (RER > 0.95). Consuming <3 g/kg/day carbohydrate results in chronically low pre-match glycogen stores, precipitating severe fatigue by minute 75 when glycogen is exhausted.
Rule (DGA & Sports Nutrition Standards): High-endurance athletes training 1 to 3 hours/day require 6 to 10 g carbohydrate/kg/day to sustain glycogen stores (74 kg 7 g/kg = 518 grams carbohydrate daily).
Solve (Acute Post-Workout Protocol): Within the 0-to-4 hour recovery window, A.V. must consume 1.0 to 1.2 g carbohydrate/kg/hour (74 kg 1.1 g = 81 grams carbohydrate per hour) paired with 22 g protein (0.3 g/kg) using whole foods (e.g., chocolate milk, rice bowls with chicken, oatmeal with bananas).
Patrón: El juego de alta intensidad depende de carbohidratos. Consumir <3 g/kg agota el glucógeno en el minuto 75. Regla: Requiere 6 a 10 g/kg/día (518 g/día). Solución: 81 g carbohidratos/hora + 22 g proteína en las 4 horas posteriores. - Bilingual Client Handout Card:
EN: "Fueling with 518 grams of daily complex carbohydrates and eating 81 grams of carbs with protein immediately after matches will refill your muscle glycogen tanks and eliminate late-game fatigue."
ES: "Consumir 518 gramos de carbohidratos diarios y 81 gramos con proteína inmediatamente después de los partidos recargará su glucógeno muscular y eliminará la fatiga al final del juego."
