Question: If running after eating is bad for you, why does the army practice this?
That's why they call it training. Its just away to train you and make your body adapt to every situation, physically and mentally.
How would you be able to do it in war time if you never did it in training? It prepares you to be able to keep your food down during rigorous physical activity. If you didn't practice it, everyone would be throwing up on the battle field.
It also makes you stronger, because the weakest people are the first to puke in that situation.
