PURPOSE: Individuals with Chronic Obstructive Pulmonary Disease (COPD) may exhibit significant reduction in physical performance due to various factors such as dynamic hyperinflation and progressive deconditioning associated with inactivity. A study in the Dead Sea suggested that COPD patients showed improvement in dyspnea and the distance traveled at lower altitudes. Objective: To evaluate the influence of altitude in the 6-minute walk test (6MWT) in patients with moderate to severe COPD

METHODS: We evaluated 29 patients with moderate to severe COPD who underwent a 6MWT in the Pulmonary Rehabilitation clinic in Santo André ( above sea level ) and at the beach in Guaruja ( sea ​​level ), 08 patients performed the test both on the sand uneven floor and on the sidewalk firm ground in order to assess whether there is any change in performance during the test and in the distance during 6MWT in lower altitude (alt=above sea level) data ( heart rate , oxygen saturation , the walk test distance and borg scale) were compared between individuals.

RESULTS: There was no difference in the walking distance above sea level and sea level, and between sand and hard floor (distance of 387.75 ± 5.02 and 375.00 in the sand ± 40.88 on the sidewalk, p = 0.654) and in saturation percentage (in the sand Sat = 95.12 ± 1.80 %, and the sidewalk Sat = 96.87 ± 1.64 %, p = 1, 05, ie, the test was reproducible in both floor. We found a good correlation between lower limb Borg scale and oxygen saturation ( p< 000,1)ie, the lower oxygen saturation, the higher the scale and the same with dyspnea scale Borg.

CONCLUSIONS: 6MWT was reproducible above and at sea level in COPD patients and performed in hard or uneven floor.

CLINICAL IMPLICATIONS: Improved quality of life for patients.
