AB  - Average acceleration (AvAcc) and intensity gradient (IG) have been proposed as 
      standardised metrics describing physical activity (PA) volume and intensity, 
      respectively. We examined hypothesised between-group PA differences in AvAcc and 
      IG, and their associations with health and well-being indicators in children. 
      ActiGraph GT9X wrist accelerometers were worn for 24-h.d(-1) over 7days by 145 
      children aged 9-10. Raw accelerations were averaged per 5-s epoch to represent 
      AvAcc over 24-h. IG represented the relationship between log values for intensity 
      and time. Moderate-to-vigorous PA (MVPA) was estimated using youth cutpoints. BMI 
      z-scores, waist-to-height ratio (WHtR), peak oxygen uptake (VO(2)peak), Metabolic 
      Syndrome risk (MetS score), and well-being were assessed cross-sectionally, and 
      8-weeks later. Hypothesised between-group differences were consistently observed 
      for IG only (p < .001). AvAcc was strongly correlated with MVPA (r = 0.96), while 
      moderate correlations were observed between IG and MVPA (r = 0.50) and AvAcc (r = 
      0.54). IG was significantly associated with health indicators, independent of 
      AvAcc (p < .001). AvAcc was associated with well-being, independent of IG (p < 
      .05). IG was significantly associated with WHtR (p < .01) and MetS score (p < 
      .05) at 8-weeks follow-up. IG is sensitive as a gauge of PA intensity that is 
      independent of total PA volume, and which relates to important health indicators 
      in children.
