Oxygen debt: When you exercise maximally, beyond your anaerobic threshold (>85% of your age-based maximum predicted heart rate (154 for you) for more than a few minutes, your muscles shift from aerobic to anaerobic metabolism and you build up an "oxygen debt" with lactic acidosis that must be paid back. The longer you continue, the more you owe. If a tiger is chasing U, it can save your life! Thus: gasping!
