Table 1 Outputs from the AM7164, GT1M and GT3X+ among 16 Norwegian 9-year-olds during 3 days of free-living data assessment (mean and SD)

From: Comparison of three generations of ActiGraph activity monitors under free-living conditions: do they provide comparable assessments of overall physical activity in 9-year old children?
