Heavier-than-normal breathing is a body response to physical exercise.
Breathing is a vital tool for good physical activity. Breathing in and out in a rhythmic and conscious manner causes oxygen to carry nutrients to the cells and assists the muscles during exercise. On the other hand, carbon dioxide is released after the process. This exchange is of utmost importance for the muscles, which gain more endurance.
When we practice a physical activity, our body is in oxygen debit, the answer to that is that the breathing gets heavier and can even make us gasp.
