Is the six-minute walk test valid for classifying cardiorespiratory fitness compared to cardiopulmonary exercise testing in adults?
The 6-minute walk test is a valid and practical alternative to cardiopulmonary exercise testing for screening and monitoring cardiorespiratory risk, particularly for identifying adults with low fitness.
