Bodies don't produce oxygen. we breathe it in.
Running causes the body to produce more blood to make oxygen to obtain stamina while walking is a low energy exercise and the build up of more blood to produce oxygen is slower.
The lack of oxygen your body has after running causes this. Your body uses up oxygen and makes it hard to take in more to substitute for the amount you are using up.
To produce more oxygen to spread throughout your body.

It causes more energy in your body when your lungs run out of oxygen(air).
Your body is an engine that uses fuel (food) to produce energy for you to do exercise. The fuel contains carbon from the carbohydrates you eat, and the body uses oxygen from the air to do a chemical reaction that combines the carbon with the oxygen to produce energy plus carbon dioxide. If you do exercise, you use more fuel and more oxygen, and you produce more carbon dioxide. The body has sensors that detect excess carbon dioxide in the blood, and they make you breathe faster to get rid of it.
the body is working extremely hard to force blood and the oxygen in the blood around the body, so by working harder you need more oxygen to travel around your muscle's, so your heart is working harder, therefore you need more oxygen.
When you exercise, your body uses up more oxygen, which your body's cells need as fuel. You also produce more waste gas (carbon dioxide) because the cells are working harder. You breathe heavily when exercising because you need to expel more carbon dioxide than usual from your lungs and take in more oxygen than usual.
