Peak VO<sub>2</sub> obtained during CPX correlated significantly with ISWT distance (<italic>r</italic> = 0·54, <italic>P</italic><0·05) and peak VO<sub>2</sub> obtained during the ISWT (<italic>r</italic> = 0·64, <italic>P</italic><0·05).

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.</p> </sec> </abstract>
