AB The 6-minute walk test (6MWT) is widely used in clinical practices to assess functional capacity and exercise resistance. Most reference equations for 6MWT in healthy subjects were established based on American and European populations, with only a few proposed for the Brazilian population. Objectives: To compare the distance walked in 6 minutes by healthy males with the predicted distance values obtained from five reference equations, evaluate the difference between them and which would be most reliable for use in the Brazilian population. Methods: We evaluated 104 individuals (mean age 34.12 ± 8.88 years), the level of physical activity, respiratory symptoms, handgrip strength and 6MWD. T Test was performed in order to compare the distance walked with the predicted distances obtained in the five reference equations. Results: The average distance walked by the participants in the 6MWT (6MWD) was 663.43 ± 93.01 meters. The predicted values that were closest to those obtained by Enright & Sherrill, Am J Respir Crit Care Med. 1998;158(5):1384-7 (640.66 ± 100.70 meters) and Iwama et al. Brazilian Journal of Medical and Biological Research 2009: 42: 1080-85 (621.27 ± 15.65 meters), which was proposed for the Brazilian population. Conclusions: We conclude that the Enright & Sherrill and Iwama et al equations can be used in order to estimate a predicted distance walked in 6 minutes in healthy Brazilian men.
