ABSTRACT

The six-minute walk test (6-MWT) is an instrument used for the evaluation of exercise tolerance, prescription and supplementary oxygen during exercise, and to evaluate the functional status after pulmonary rehabilitation, thoracic surgery or lung transplantation. There are no reports on the distance covered in the test by the healthy Mexican population, we therefore considered it necessary to standardize this test. Objective: To standardize the 6-MWT for a group of healthy Mexican subjects. Methods: This descriptive cross-sectional study included 200 healthy subjects, aged 40 ± 16 years. All subjects were evaluated using chest X-rays, spirometry and 12-lead EEG. Measurements for evaluation of respiratory muscle force (Pimax and Pemax) were also registered. All subjects performed two different 6-MWT (one at a “normal” speed and another at a fast speed) on a 25m long open corridor. Results: A total of 89 men and 119 women were studied. The mean overall distance covered during the first 6-MWT (“slow”) was 481.51 ± 51m for men and 463 ± 55m for women (p= 0.001). For the second (“fast”) test mean values were 605 ± 56m and 563 ± 57m for men and women respectively (p= 0.001). The models for the slow walk showed no statistical significance but for the fast walk they showed significance with respect to age, gender and body mass index (p‹ 0.01). Conclusions: These results show that anthropometric characteristics such as age, gender and body mass index are factors which determine the distance covered during the fast 6-MWT.
