Introduction:

Functional tests are important clinical instruments, because they are non-invasive methods, easy to apply, low cost, and require the study of their psychometric properties.

Objective.

To evaluate the consistency of the 2-minute walk test in healthy people aged 18 to 69 years.

Methodology:

Psychometric evaluation of test-retest and intra- and inter-rater reproducibility and level of agreement of the 2-minute stationary walking test in healthy individuals of both sexes, aged 18 to 69 years, with a 7-day interval. The intraclass correlation coefficient (ICC) and Bland-Altman limits of agreement were used.

Results.

The study sample included 101 participants, predominantly men from middle socioeconomic backgrounds, physically active, and overweight. The 2-minute walk test demonstrated excellent reliability, both in the test-retest (ICC ≥ 0.97) and interrater (ICC ≥ 0.97) assessments. The lower and upper limits of agreement were -26.26 and 19.88, respectively, with 7% of the values outside the 95% confidence interval.

Conclusion.

The 2-minute stationary walk test is a reliable measure to measure the aerobic capacity of apparently healthy individuals, considering different times and examiners.
