ResumoAbstract Objective To establish reference values for the 6‐min walk test in healthy children and adolescents aged 6–12 years. Methods This cross‐sectional, prospective study selected healthy children and adolescents aged 6–12 years, at three elementary schools in Porto Alegre. The anthropometric data of all the individuals were evaluated and two 6‐min walk tests were performed. Based on this, a reference equation was generated, and the test reproducibility was evaluated. Results One hundred eighty‐eight children (92 boys) performed the test. Pearson correlation showed that age (r = 0.51), height (r = 0.49), difference in heart rate before and after the test (dif. HR) (r = 0.30), and weight (r = 0.29) were significantly correlated with the distance covered in 6 min. The best multiple regression model included these four variables resulting in the following equation: 145.343 + [11.78 × age (years)] + [292.22 × height (m)] + [0.611 × dif. HR (bpm)] − [2.684 × body weight (kg)]. The intraclass correlation coefficient confirmed the reproducibility among tests. Conclusion The reference equation for the 6‐min walk test was generated and the distance covered is influenced by age, height, difference in heart rate before and after the test, and body weight.
