- Abstract
- The purpose of this study was to develop Actical count cut-points for overweight adults that correspond to moderate and vigorous intensity exercise. The standard definitions of moderate (3 METS) and vigorous (6 METS) were used. Cut-points in overweight subjects (OW) were also compared to cut-points in normal weight (NW) subjects. Thirty overweight (BMI >25 kg/m) male and female adults completed a progressive submaximal exercise session on a treadmill while oxygen uptake was measured. The activity count cut-point derived from ROC curves for moderate intensity was 1839 for OW and 1994 for NW and cut-points for vigorous intensity were 3900 for OW and 4381 for NW. Activity count thresholds were greater in the NW compared to the OW subjects at both moderate and vigorous intensities.
