Lungs: How They Work

If you’re preparing for an exam, getting ready for a meeting, or are just simply curious, the following information about breathing should be kept in mind.

The lungs of the average individual moves approximately 0.5 L worth of air whenever a relaxed breath is taken. This amount may spike up to 3 L when exercising vigorously.

The Surprising Results That Come with Breathing Improperly

The diaphragm can be described as a muscle in the shape of the dome situated under the lungs. Whenever you inhale, the diaphragm moves downward in a flattening position.

It presses against your abdominal organs, allowing your lungs to expand. With that said, some adults don’t engage their diaphragms properly. Stress, poor posture, and other aspects cause people to start breathing shallowly.

This makes your upper rib cage move more than necessary. Such movement may result in back and chest muscle discomfort. It may also weaken lower back or pelvic floor muscles, as well as disrupt the way the spine and shoulders naturally move.

To show clients how to achieve correct diaphragmatic breathing, their hands should be placed on the lower rib area. That way, clients will be able to feel the ribs fall and rise when breathing.

Most of this breathing motion will be felt in this area, as opposed to your upper chest, not just during exercise, but all day long.

How Much Do You Know About Lung Disease?

Lung disease is a condition that stops the proper functionality of this vital organ. People suffering from lung disease usually experience fatigue and breath shortness a lot faster when exercising.

The following refresher can offer several guidelines when you are working with clients who have lung disease (assuming their doctors have approved exercise for them).

The Proper Way of Breathing When Exercising

When it comes to strength training, exhaling should happen during exertion, while inhaling should happen during relaxation. For cardiovascular exercises, you should be breathing out and in through your nose.

When the intensity revs up, mouth breathing is encouraged. Consider the following breath control techniques to use with clients.


RMT (Respiratory Muscle Training) involves breathing exercises that can build muscles up – specifically ones that have a connection to respiration. Sometimes, unique devices are used for this activity. A study was conducted in 2013 at the University of British Columbia on RMT.

Thousands of participants were systematically interviewed for the sake of narrowing down the subjects to 21 people.

Their findings revealed that RMT is capable of improving sports performances, but researchers weren’t able to determine why. RMT displayed no increase of VO2 max.

Many have speculated that RMT might postpone breathlessness (or at least an onset of it), allowing athletes and exercisers to push much harder for a longer period of time.
