Abstract
The individual’s response to exercise is an important clinical assessment tool, since it provides a composite assessment of their respiratory, cardiac and metabolic systems. The current gold standard for assessing a person’s aerobic exercise response is the maximum incremental cardiopulmonary exercise test. However, most daily activities are performed at submaximal levels of exertion and, therefore, it has been proposed that submaximal functional tests are a better reflection of physical capability. The ability to walk a set distance is a quick, easy and inexpensive way to assess physical function. It is also an important component of quality of life, since it reflects the capacity to undertake day-to-day activities. A recent review of functional walking tests concluded that the 6-min walk test (6MWT) is easier to carry out, more acceptable and provides a better reflection of activities of daily living than other walk tests. The six-minute walk test (6MWT) has been frequently used in the last decade to evaluate the submaximal effort of an individual, the 6MWT is easy to administer, better tolerated, and more closely reflects the activities of daily life. The test can be used to monitor the progress of disease and response to therapy in patients with various diseases. However, the most common use of 6MWT is in pulmonary and cardiovascular diseases. The 6MWT is a reliable test for the assessment of physical fitness. It evaluates the global and integrated responses of all the systems involved during exercise, including the pulmonary and cardiovascular systems, systematic circulation, peripheral circulation, blood, neuromuscular units and muscle metabolism.
