# Design Recovery Nutrition Protocol

Optimize post-exercise nutrition to maximize glycogen restoration, muscle repair, and rehydration — with timing, quantity, and food selection matched to the athlete's recovery window.

## Why This Is Best Practice

**Why best:** Post-exercise nutrition timing and dosing directly accelerates glycogen resynthesis and muscle protein synthesis, translating into measurably faster recovery between sessions.
**Adopted by:** AIS, USOC, and all major elite sport nutrition programs provide athletes with post-training recovery nutrition as part of daily support. EPL clubs and NBA franchises deliver structured post-training recovery meals (protein shakes, carbohydrate sources) immediately after sessions — treating post-workout nutrition as a performance intervention, not optional.
**Impact:** Ivy et al. (2002) showed that consuming carbohydrate immediately post-exercise vs. waiting 2 hours accelerated glycogen resynthesis by 45%. Moore et al. (2009) established the dose-response for muscle protein synthesis — 20-40g high-quality protein (depending on body mass) maximally stimulates MPS, with leucine content being the primary trigger. When recovery between sessions is <8-12 hours, aggressive early nutrition significantly impacts performance in the subsequent session.

## Steps

### 1. Identify the recovery priority

Different sessions require different recovery focuses:
- **<8 hours to next session:** glycogen resynthesis is top priority — carbohydrate is critical; protein is second
- **Strength/hypertrophy session:** protein synthesis is top priority — protein dose is critical; carbohydrate is secondary
- **Long endurance session (>2 hr):** both glycogen and protein are critical — maximize both
- **Light session (<60 min):** normal next meal is sufficient; immediate recovery nutrition not critical

### 2. Time the recovery nutrition window

The anabolic window is real but wider than previously believed:
- **Optimal:** consume within 30-60 min post-exercise for maximum glycogen resynthesis rate
- **Acceptable:** within 2 hours post-exercise for most athletes
- **Critical (rapid recovery situations):** consume within 30 min if next session is <8 hours

For most recreational athletes training once per day with adequate daily intake: the window effect is small. For twice-daily athletes or those with consecutive competition days, the window matters significantly.

### 3. Set carbohydrate dose

For glycogen resynthesis:
- **Rapid recovery (next session <8 hours):** 1.0-1.2 g/kg body mass/hour for 4 hours = very high intake; use high-GI carbohydrates to maximize resynthesis rate
- **Normal recovery (>24 hours):** meet daily carbohydrate targets from subsequent meals; immediate post-exercise carbohydrate less critical
- **Practical examples:** banana + 500mL sports drink; bowl of rice + fruit juice; chocolate milk (also provides protein)

### 4. Set protein dose

For muscle protein synthesis:
- **Optimal dose:** 0.3-0.4 g/kg body mass per meal (approximately 20-40g for most athletes)
- **Leucine threshold:** ensure at least 2-3g leucine to trigger MPS — present in 20g+ of whey or 3 eggs
- **Protein quality:** whey > casein > soy > plant proteins for acute MPS, but total daily protein over 24 hours matters more than source for most outcomes
- **Practical examples:** 3 eggs; 200g chicken breast; 30g whey protein powder; 250mL Greek yogurt; 300g cottage cheese

### 5. Restore fluid and electrolytes

Rehydrate as per `apply-hydration-protocol`:
- Begin rehydrating immediately post-exercise
- 125-150% of fluid deficit over 4-6 hours
- Include sodium (food, electrolyte drink) to retain fluid

Many practical recovery foods provide both carbohydrates and sodium (chocolate milk, recovery bars, real food meals with salt).

### 6. Use food first, supplements when impractical

Recovery nutrition hierarchy:
1. **Real food meal:** most complete nutritional profile; preferred when time and access allow
2. **Chocolate milk:** well-evidenced recovery beverage (3:1-4:1 carb:protein ratio, sodium, fluids); inexpensive and effective
3. **Commercial recovery shake + food:** when a full meal is not possible within the window
4. **Protein + carbohydrate supplement alone:** last resort when food access is impossible

## Common Mistakes

- **Only consuming protein, ignoring carbohydrates after endurance session:** Insulin from carbohydrates co-stimulates MPS and is required for glycogen resynthesis; protein alone post-endurance is insufficient.
- **Waiting for appetite to return:** Exercise suppresses appetite for 30-90 min in many athletes. Waiting = missing the recovery window. Liquid nutrition (shake, smoothie, chocolate milk) is easier to consume when appetite is low.
- **Protein above 40g per meal:** No additional MPS benefit from >0.4g/kg protein in a single dose; excess is oxidized for energy.

## When NOT to Use

- Rest days: recovery nutrition timing is irrelevant; meet daily macronutrient targets across normal meals.
- Athletes in active weight loss phases: nutrient timing is secondary to total daily intake and deficit management.
