Chronic Obstructive Pulmonary Disease (COPD) leads to a reduction in exercise capacity that affects the quality of life and increases mortality of these patients. So, exercise tests are considered as an essential component of the clinical evaluation of the patients with COPD. The objective of this study is to evaluate the reproducibility sensitivity and validity of the Six Minute Step Test (6MST) in patients with COPD and in health volunteers, and verify its relation with the "Body-Mass Index, Airways Obstruction, Dyspnea and Exercise Capacity" Index (BODE). This Observational, Transversal, Prospective study will be conducted in the "Special Unit of Respiratory Physiotherapy", of the "Federal University of São Carlos". To participate in this study, 120 subjects, both gender, will be invited and will be allocated in five groups: Group I (30 healthy young subjects of 17 to 27 years old), Group II (30 healthy elderly individuals of 60 to 75 years old), and patients COPD, 60 to 80 years old, with mild, moderate, severe and very severe obstruction determined by the forced expiratory volume in one second (FEV1) by forced vital capacity (FVC) relation "FEV1/FVC" <70% and FEV1 in predict percentage < 80% composing the Group III (20 COPD patients in GOLD stage I), Group IV (20 COPD patients in GOLD stage II) and Group V (20 patients COPD stages III and IV). All subjects will be submitted to body composition and anthropometric assessment, pulmonary function test, three 6-minutes walk test (6MWT) and three 6MST. Furthermore, the patients of the groups III, IV and V will answer the Modified Medical Research Council (mMRC) scale, and BODE index will be calculated to each of them.

The enrolled patient's and subject's numbers were smaller than the estimated for healthy elders and different COPD groups, because of the low acceptance of a three days evaluation protocol. So COPD patients were analyzed in a single group.

It is composed by other commonly used evaluations tools in COPD, Forced Expiratory Volume in the First second (from spirometry); classification in the scale ranging from 0-3, Body-mass index, classification in the scale ranging from 0-1; Six-minute walk test distance, classification in the scale ranging from 0-3 and referred dyspnea, classification in the scale ranging from 0-3. It was only used the total score (0-10) | 2 COPD were excluded since they did not appeared in the second day of evaluation. The other two populations were not verified, since the measure is specific for COPD patients | Posted | Median | Inter-Quartile Range | units on a scale | Second day |

| Secondary | First "Six Minute Walk Test" Exertion Perception | This test was conducted by the "Rater 1", the subject walked as far as it could in a 30m corridor during 6 minutes. The Exertion Perception will be evaluated using BORG scale. This scale is a self-reported scale, which range from 0 to 10, where 0 means none exertion perception and 10 means very intense exertion perception (the highest the patient has ever felt). Lower values means that the patient feel less discomfort. | 2 COPD patients and 2 healthy young individuals were excluded since they did not appeared in the second day of evaluation. | Posted | Median | Full Range | units on a scale | First day or second day of the protocol (random) |

This scale is a self-reported scale, which range from 0 to 10, where 0 means none exertion perception and 10 means very intense exertion perception (the highest the patient has ever felt). Lower values means that the patient feel less discomfort. | 2 COPD patients and 2 healthy young individuals were excluded from the study since they did not appeared in the second day of evaluation. 3 COPD patient Analysis Population Description: s and 5 elderly subjects didn't show on the third day of evaluation, then, they were just excluded in the analysis of the variables collected in this day. | Posted | Median | Full Range | units on a scale | On the third day of evaluation, seven days after the first day of evaluation. Since it was performed in the same day of the third 6MST, the choice of the first test was random, and there was a 30 minute interval between them. |
