Jesus Christ already.
When was the last time you sprinted full bore? And what happened when you did?? You started breathing hard! REALLY hard! Hands on your knees, gasping for breath, out of air. Muscles feel fine, but you're 100% out of air. And after a few minutes of breathing, you're back and ready to go.
Your body needs practice taking in and consuming oxygen, exhaling CO2, and doing so in an extreme, adrenaline induced manner. The more you do it, the better your body gets at it.
Martial arts is not just an aerobic activity. When you push yourself really hard, your body uses its anerobic energy stores, then its lactic acid, then its aerobic energy. When you bust your ass going for something big, your body burns its ATP (andenosine tri-phosphate) first, its anerobic fuel source, and then starts using its lactic acid and aerobic energy stores, requiring you to breathe heavily so that your aerobic capacity can temporarily make up for the loss of ATP and get rid of the built up CO2.
So, do High Intensity Interval Training. Do shorts burst of activity that leave you completely out of breath. Rest, repeat. This will train your body to increase its anerobic abilities, and help condition it to recover more quickly. It'll train your body how best to use the oxygen it has, and to quickly exchange O2 and CO2.
The whole ATP thing is just wrong. ATP is the final outcome of the Krebs sycle (glucose) or fatty acid (fat) or just Glucolisa. ATP is the energetic mediator, and nothing can replace it i repeat nothing ATP is the final outcome for energy production by burning sugar with O2 OR Fatty acids with even more O2 or the An aerobic glycolysis, they all produce ATP just in different amounts and ways. "GLYCOLYSIS: The series of biochemical reactions in which glucose is broken down to pyruvate with the release of usable energy in the form of ATP. One molecule of glucose undergoes two phosphorylation reactions and is then split to form two triose-phosphate molecules. Each of these is converted to pyruvate. The net energy yield is two ATP molecules per glucose molecule. In aerobic respiration pyruvate then enters the Krebs cycle. Alternatively, when oxygen is in short supply or absent, the pyruvate is converted to various products by anaerobic respiration. Other simple sugars, e.g. fructose and galactose, and glycerol (from fats) enter the glycolysis pathway at intermediate stages.

You can even take a more alaborate test (V02 MAX) with a mask on that messures your gass exchange, that will tell you all the things you need to know, forget the crap about food allergies that is just stupid. It shouldn't be too expensive because they make athletes do it for enssurence (Hell even i had 2, one for boxing and one at med school while we studied physiology of stress and breathing.
