Summary Objective The aim of this study was to evaluate the test–retest reliability, concurrent validity and agreement with peak oxygen uptake ( VO 2 ) obtained during cardiopulmonary exercise testing ( CPX ) on a treadmill for the incremental shuttle walking test ( ISWT ) in obese women. Methods Prospective study with a convenient sample of 46 community‐dwelling obese women ( BMI > 30 kg m −2 ). The main outcome measures were walking distance on the ISWT and peak VO 2 . Results Test–retest reliability was good to excellent for the exercise tests ( ISWT distance ICC : 0·90; and CPX peak VO 2 ICC : 0·90). Peak VO 2 obtained during CPX correlated significantly with ISWT distance ( r = 0·54, P <0·05) and peak VO 2 obtained during the ISWT ( r = 0·64, P <0·05). Bland and Altman plots demonstrated a high degree of repeatability. Conclusion The ISWT had excellent reliability as well as good concurrent validity and agreement. The ISWT may be a potential tool for monitoring clinical status and intervention efficacy (e.g. programmes for weight loss and rehabilitative strategies) in this population.
