Fuelling the muscles
With each breath we take, oxygen is delivered to the muscle cells to provide the energy that powers movement. The faster the body moves or the harder it works, the more oxygen the cells need. So our breathing speeds up in order to take in, then deliver, more oxygen to where it is needed.
Breathing rates
Breathing rate, or speed, depends on a person’s age, size, health, and fitness level as well as on what they are doing. This shows a typical adult’s breathing rates when they are taking part in different activities.
A normal breathing rate for an adult at rest is 8 to 16 breaths per minute. For an infant, a normal rate is up to 44 breaths per minute.
- Reading 15 breaths per minute
- Walking 20 breaths per minute
- Jogging 40 breaths per minute
- Running fast up to 70 breaths per minute
Fitness and breathing
When we exercise, we breathe heavily to take in extra oxygen. With regular exercise, the lungs increase their ability to hold air, and our bodies get more efficient at using the oxygen they take in. this means we don’t have to breathe as fast to get the same amount of oxygen to the muscles.
Fighting fit
The more physically fit a person is, the easier they will find it to work out in the gym, dance, or run for a bus, without panting or getting out of breath.
