Maximum Breathlessness Test (MBT)

The maximum breathlessness test measures an individual’s maximum number of paces when walking while holding their breath after exhalation. The test is commonly used to evaluate lung function, especially in people with respiratory disorders or to monitor the progression of a disease over time. The results of the test can help healthcare professionals diagnose conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory conditions.

Function & Dysfunctional Breathing based on MBT

An optimal MBT score lies between 80 and 100 paces. When a person scores 60 or more paces, his breathing is functional.  Below 60 means the breathing is dysfunctional.

Instructions MBT

  • Ind  and exhale normally through the nose
  • Walk at a normal pace
  • Exhale normally and then hold your nose with two fingers to prevent air from entering your lungs.
  • Count the number of paces that you can hold your breath for.
  • Then resume normal nasal breathing. Breathing should be under good control after the breath holds.
