Nutrition & Recovery Timing for S&C Coaches
The anabolic window is real. It is also much wider than the supplement industry wants you to believe. Here is what coaches actually need to know about fueling recovery.
Recovery › Nutrition & Recovery Timing
Getting the Basics Right First
Before getting into timing, a necessary reframe: the single most impactful nutritional variable for recovery is total daily intake. An athlete who eats enough protein, enough carbohydrate, and enough total calories across the day will recover substantially better than an athlete who is chronically under-fueled but times their post-workout shake perfectly.
Timing matters. But it matters most on top of an adequate foundation. The supplement industry has spent decades emphasizing the window precisely because it sells products. Get total intake right first, then optimize timing.
This page covers the science on post-training nutrition and timing, what actually moves the needle for recovery, and the practical protocols that work in real team and individual settings.
The Foundation
What Athletes Actually Need to Recover
Recovery nutrition serves three primary physiological goals: replenishing glycogen stores, supporting muscle protein synthesis, and reducing exercise-induced inflammation. Each maps to a specific macronutrient and time window.
Carbohydrates: Glycogen Replenishment
MOST URGENT POST-TRAINING
Muscle glycogen is the primary fuel for high-intensity training. Depleted glycogen is one of the primary drivers of fatigue and impaired performance in subsequent sessions. Carbohydrate is the only macronutrient that directly replenishes glycogen. Synthesis rate is fastest in the 30-60 minutes immediately post-exercise, then gradually slows over the next several hours.
Recommended intake:
1.0-1.2g carbohydrate per kg bodyweight in the first hour post-training for maximal glycogen resynthesis. For a 180lb (82kg) athlete, that is approximately 80-100g.
When it matters most:
Two-a-day sessions, back-to-back competition days, or any scenario where less than 8 hours separates training sessions. With adequate time between sessions (24+ hours), total daily carbohydrate matters more than timing.
Protein: Muscle Protein Synthesis
WINDOW IS WIDER THAN MARKETED
Resistance training elevates muscle protein synthesis (MPS) for up to 24-48 hours post-session. The “anabolic window” of 30 minutes that fueled a generation of supplement marketing reflects an earlier, less complete understanding of the research. Current evidence suggests that for athletes who consumed protein in the 3-4 hours before training, immediate post-training protein is considerably less critical. The window that matters is the full 24-hour period, not 30 minutes.
Recommended intake:
0.25-0.40g per kg bodyweight per meal, distributed across 3-5 meals throughout the day. 20-40g high-quality protein post-training is appropriate and sufficient.
Protein quality matters:
Leucine content is the primary driver of MPS stimulation. Whey protein is high in leucine and rapidly absorbed. Whole food sources (chicken, eggs, fish, beef) are equally effective when consumed in adequate amounts.
Fluids & Electrolytes: Rehydration
UNDERVALUED IN PRACTICE
Even mild dehydration (1-2% body weight) impairs performance and slows recovery. Many athletes finish training in a net fluid deficit and don’t rehydrate adequately before their next session. Rehydration is not just water: sodium drives fluid retention, and sweat contains significant sodium that plain water does not replace.
Practical target:
1.5L of fluid for every 1kg of body weight lost during training. Urine color is a reliable guide: pale yellow is the target, dark yellow indicates under-hydration.
Electrolytes:
Sodium (400-800mg per hour of heavy sweating), potassium, magnesium. Sports drinks, electrolyte tablets, or sodium-containing foods all work. Plain water alone is insufficient after heavy sweat sessions.
The Anabolic Window
What the Science Actually Says About Timing
The concept of the anabolic window has been distorted significantly from the original research. The evidence, read clearly, tells a more useful story.
The window exists, but it is not 30 minutes
The elevated sensitivity of muscle tissue to protein and carbohydrate persists for several hours post-exercise, not 30 minutes. A 2013 meta-analysis by Aragon and Schoenfeld concluded that the practical window is the roughly 4-6 hours surrounding the training session. Athletes who ate a substantial pre-workout meal 2-3 hours before training showed no significant advantage from an immediate post-workout shake compared to eating a normal meal within 2 hours of training completion.
The window matters most in specific contexts
Fasted training (morning sessions with no pre-workout meal) shifts the priority calculus. When an athlete has been fasted for 8+ hours, post-training protein and carbohydrate become more time-sensitive. The same applies to two-a-day sessions, where glycogen replenishment within the first hour is genuinely important for afternoon performance. Fasted or back-to-back training raises the urgency of immediate post-training nutrition substantially.
Pre-workout nutrition is equally important
Athletes who eat a mixed meal containing protein and carbohydrate 2-3 hours before training arrive with elevated amino acid availability, which extends the effective window well past the end of training. Obsessing over the immediate post-workout shake matters much less than eating a solid pre-workout meal. For many athletes, getting the pre-training meal right is the higher-leverage intervention.
Pre-sleep protein is the most underused window
Research by Res et al. and subsequent work by Snijders and van Loon demonstrated that 40g of casein protein consumed 30 minutes before sleep significantly increases overnight muscle protein synthesis without disrupting sleep quality. For athletes in heavy training blocks, a pre-sleep protein source (Greek yogurt, cottage cheese, casein shake) is one of the most evidence-supported timing interventions available.
The honest hierarchy
In order of impact: (1) Total daily protein. (2) Total daily carbohydrate calibrated to training load. (3) Pre-training meal quality and timing. (4) Post-training meal within a reasonable window (1-2 hours). (5) Pre-sleep protein in high-demand blocks. The supplement industry has inverted this hierarchy for decades. Coaches who get the first two right and then optimize the rest will see substantially better outcomes than coaches who obsess over timing while athletes walk around chronically under-fueled.
Practical Protocols
What to Do in Real-World Conditions
Coaches deal with bus rides, late practice times, cafeteria schedules, and athletes who skip meals. These protocols work under real constraints.
Single Daily Session
Standard Training Day
Pre-training meal 2-3 hours before: mixed carbohydrate and protein, moderate fat
Post-training: 20-40g protein + 40-80g carbohydrate within 1-2 hours of session end
A real meal beats a rushed shake; total daily intake matters more than strict timing
Pre-sleep: 30-40g protein (cottage cheese, Greek yogurt, casein) in heavy training blocks
Two-a-Days / Back-to-Back
High-Demand Blocks
Carbohydrate within 30 minutes of AM session end: 1.0-1.2g/kg bodyweight
Protein co-ingested with carbohydrate enhances glycogen resynthesis rate by 35-40%
Practical options: chocolate milk, rice + chicken, or a 3:1 or 4:1 carb:protein recovery shake
Do not allow athletes to skip post-AM nutrition in favour of showering or meetings
Travel Days
Away Competition
Travel disrupts eating patterns as reliably as it disrupts sleep; plan protein and carbohydrate sources for the bus or flight
Portable options: protein bars (20g+), trail mix, jerky, Greek yogurt, rice cakes with peanut butter
Pre-competition meal: high-carbohydrate, moderate protein, low fat and fibre to minimize GI distress
Post-game: prioritize protein and carbohydrate before the bus ride home, not after
Late Evening Training
Night Practice / Late Games
Athletes training at 8-10pm face a real conflict between recovery nutrition and sleep quality
Resolution: a moderate meal with protein and carbohydrate immediately post-training, then sleep
High-fat, high-fibre meals late at night delay gastric emptying and impair sleep; keep it simple
Chocolate milk, a small rice bowl, or a protein shake with fruit covers the recovery goal
Daily Targets
Reference Numbers for Coaches
Coaches are not dietitians and shouldn’t try to be. A working knowledge of intake targets makes conversations with athletes and support staff more useful.
Protein
1.6-2.2g
Per kg of bodyweight per day for strength and power athletes. Higher end applies during aggressive training blocks or caloric restriction. Distribute across 3-5 meals rather than front- or back-loading.
Carbohydrate
4-7g
Per kg per day for moderate-to-high training loads. Endurance-dominant athletes and two-a-day blocks may need 7-10g/kg. Scale down on rest or low-intensity days.
Calories
+500-800
Above maintenance during serious muscle-building phases. Most strength athletes trying to add mass are under-eating, not over-eating. Athletes who can’t gain despite eating “a lot” should track calories for one week; the gap between perceived and actual intake is almost always larger than expected.
A note on under-fueled athletes
Chronic energy deficiency (RED-S) is common across all sports and genders, not just endurance athletes or those with disordered eating. Athletes who are chronically tired, not recovering, failing to make strength gains, getting injured frequently, or losing lean mass may be under-fueled. These are nutrition problems, not training problems. Refer to a registered sports dietitian; do not try to troubleshoot in-house.
