BLOOD FLOW SHUTDOWN
80% Less Blood
- Your body is a superhero, sending blood to your muscles, heart, and lungs.
- This means your stomach and gut get way less blood when you're pushing hard.
WHAT IS GI ISCHEMIA?
It's when your stomach and gut don't get enough oxygen.
- Happens during super intense, long competitions like the Heptathlon.
- Makes you feel super nauseous and unable to eat solid food.

Implementation
What stalls progress vs what moves it
Specific-population manuals work best when the plan fits the athlete's actual event demands.
What stalls progress
- Copying a generic plan from a different event
- Chasing one supplement before the food pattern is stable
- Waiting until the athlete feels broken before acting
What moves it
- Match the plan to the event load and appetite pattern
- Keep food, hydration, and screening simple enough to repeat
- Use one coach or parent follow-up step this week
