Developing and validating equations to predict
Study Goal
The researchers aimed to develop new prediction equations for maximal oxygen consumption (V̇O₂) using the 6-Minute Walking Test (6MWT) in childhood ALL survivors.
Results Summary
The study established new clinical V̇O₂ prediction equations based on the 6MWT, suggesting its utility in assessing cardiorespiratory fitness in this population. The abstract implies the 6MWT is a viable method for functional capacity evaluation, though full results are not detailed.

INTRODUCTION: The 6-Minute Walking Test (6MWT) is a safe, standardized and well utilized method to assess the functional capacity. Recently, it was reported that the published prediction equations cannot accurately predict a valid maximal oxygen consumption (V̇O METHODS: A total of 200 childhood ALL survivors were enrolled in this study, among which 168 participants underwent a cardiopulmonary exercise test and a 6MWT to assess their functional capacity and their cardiorespiratory fitness. In addition, participants completed a physical activity questionnaire. Participants were randomly divided in two groups to establish the equations ( RESULTS: The new establish clinical V̇O CONCLUSION: This is the first study that predicted V̇O
