All our muscles need oxygen to function correctly. The more we move, the more oxygen we need. Breathing is an automatic and involuntary movement but we can control it when we want to breathe faster or slower.
Breathing has two place:
-Inhalation, when we breathe in and fill our lungs with air.
-Exhalation, when we exhale and the air leaves our lungs.
If for some reason, voluntary or involuntary, we stop breathing, we call it apnea.

-Measure your breathing. Try running different lengths at different speeds. At the end of each run, sit down and breathe. Count how many times you breathe and complete this chart.
