Carbohydrates as a CNS Fuel: Why Throwers Still Need Carbs
Debunking the 'protein-only' myth for big athletes by explaining how the central nervous system rapidly depletes blood glucose during explosive throws.
Why this matters
A common nutritional error among strength and throwing athletes is the assumption that because they don't run miles, they don't need carbohydrates, leading them to focus exclusively on extreme…

DAILY CARB GOAL
300-500 Grams of Carbs
- Fuel your brain and muscles for explosive power.
- Keeps you from hitting the wall during long practices.
YOUR BRAIN NEEDS CARBS!
Your brain runs on glucose (sugar from carbs).
- Explosive throws demand huge brain power.
- Low carbs = tired brain = weak throws.
MUSCLES LOVE CARBS TOO!
Fast, powerful moves use stored carbs (glycogen).
- Long practices burn through these carb stores.
- No carbs = no energy for reps or lifting.
The Intramuscular Glycogen Demand
Explosive, 1-to-3 second movements utilize the Phosphagen system, which uses ATP, not oxygen or fat.

### The CNS Carbohydrate Rule
A competitive high school or collegiate thrower (Shot Put, Discus, Hammer) should easily consume between 300 to 500 grams of carbohydrates daily.

Protocol
Fueling the Central Nervous System
While distance runners use carbs to fuel their skeletal muscle during a 10K, throwers use carbohydrates to fuel their Central Nervous System (CNS) and Fast-Twitch Fibers.
The brain operates almost exclusively on glucose.
When a thrower executes 50 maximal-effort standing throws and full glides, the…
If blood glucose is low (from following a low-carb diet), the CNS fatigues rapidly. The…
