Yup i do
GI is very important in regards to sports performance.
For example i see alot of players gobble up lollies after a game.
This is good as the muscles need to restore the glycogen to their depleted muscles.
This must be done quickly as there's only a small window of time to get the sugars back in there.
Thats about the only time a high GI is going to aid you as there's a payback (sugar low) that follows due to increased Insulin levels.
When that kicks in you'll feel falt. Before that happens you need to eat a balance (protien, carb & good fat) meal. Low GI.
That'll sort you out for 2-3 hours more.
Then another meal. Obviously the whole time drinking fluids (but not sugary fluids)
So by now food recovery is complete.
Back to full force.
I can go into more detail if you like?
