  HOW THE EXPAND-A-LUNG WORKS

 

Breathing Resistance Exercise

The flow of air in and out of the alveoli is called ventilation and has two stages: inspiration (or inhalation) and expiration (or exhalation).  To accomplish this, the whole thorax moves and changes size, due to the action of two sets of muscles: the intercostal muscles and the diaphragm.  These are the muscles that are strengthened by using the Expand-A-Lung Breathing Resistance Exerciser.  

Inspiration (Inhaling) with resistance: 

  • The diaphragm contracts and flattens downwards
  • The external intercostal muscles contract, pulling the ribs up and out
  • The volume of the thorax increases
  • More air is delivered deeper into the lungs
  • The lung and alveoli volume increases
  • More oxygen is absorbed 

Expiration (Exhaling) with resistance: 

  • The abdominal muscles contract, pushing the diaphragm upwards
  • The internal intercostal muscles contract, pulling the ribs downward
  • This gives a larger and faster expiration
  • More CO2 is expulsed  

In essence, you inhale more oxygen, and you exhale more carbon dioxide.  The result is a substantial improvement in shortness of breath and endurance through better breathing. All is done naturally, with the help of the Expand-A-Lung Breathing Resistance Exerciser.
