    • Absolute intensity thresholds for tri-axial wrist and waist accelerometer-measured movement behaviors in adults 

      Mielke, Gregore Iven; de Almeida Mendes, Márcio; Ekelund, Ulf; Rowlands, Alex V.; Reichert, Felipe Fossati; Crochemore-Silva, Inacio (Peer reviewed; Journal article, 2023)
      Aim: This study was aimed to: (1) compare raw triaxial acceleration data from GENEActiv (GA) and ActiGraph GT3X+ (AG) placed on the non-dominant wrist; (2) compare AG placed on the non-dominant and dominant wrist, and ...

    • Comparability of accelerometer signal aggregation metrics across placements and dominant wrist cut points for the assessment of physical activity in adults 

      Migueles, Jairo H.; Cadenas-Sanchez, Cristina; Rowlands, Alex V.; Henriksson, Pontus; Shiroma, Eric; Acosta, Francisco M.; Rodriguez-Ayllon, Maria; Esteban-Cornejo, Irene; Plaza-Florido, Abel; Gil-Cosano, Jose J.; Ekelund, Ulf; van Hees, Vincent T.; Ortega, Francisco B. (Peer reviewed; Journal article, 2019)
      Large epidemiological studies that use accelerometers for physical behavior and sleep assessment difer in the location of the accelerometer attachment and the signal aggregation metric chosen. This study aimed to assess ...

    • The physical behaviour intensity spectrum and body mass index in school-aged youth: A compositional analysis of pooled individual participant data 

      Fairclough, Stuart J.; Hurter, Liezel; Dumuid, Dorothea; Gába, Ales; Rowlands, Alex V.; del Pozo Cruz, Borja; Cox, Ashley; Crotti, Matteo; Foweather, Lawrence; Jones, Owen R.; McCann, Debroah A.; Noonan, Robert J.; Owen, Michael B.; Rudd, James Robert; Taylor, Sarah L; Tyler, Richard; Boddy, Lynne M; Graves, Lee E. F. (Peer reviewed; Journal article, 2022)
      We examined the compositional associations between the intensity spectrum derived from incremental acceleration intensity bands and the body mass index (BMI) z-score in youth, and investigated the estimated differences in ...

    • Reference values for wrist-worn accelerometer physical activity metrics in England children and adolescents 

      Fairclough, Stuart J.; Rowlands, Alex V.; del Pozo Cruz, Borja; Crotti, Matteo; Foweather, Lawrence; Graves, Lee E. F.; Hurter, Liezel; Jones, Owen; MacDonald, Mhairi; McCann, Deborah A.; Miller, Caitlin; Noonan, Robert J.; Owen, Michael B.; Rudd, James Robert; Taylor, Sarah L.; Tyler, Richard; Boddy, Lynne M. (Peer reviewed; Journal article, 2023)
      Background: Over the last decade use of raw acceleration metrics to assess physical activity has increased. Metrics such as Euclidean Norm Minus One (ENMO), and Mean Amplitude Deviation (MAD) can be used to generate metrics ...

    • Utilization and harmonization of adult accelerometry data: review and expert consensus. 

      Wijndaele, Katrien; Westgate, Kate; Stephens, Samantha K.; Blair, Steven N.; Bull, Fiona C.; Chastin, Sebastien F. M.; Dunstan, David W.; Ekelund, Ulf; Esliger, Dale W.; Freedson, Patty S.; Granat, Malcolm H.; Matthews, Charles E.; Owen, Neville; Rowlands, Alex V.; Sherar, Lauren B.; Tremblay, Mark S.; Troiano, Richard P.; Brage, Søren; Healy, Genevieve N. (Journal article; Peer reviewed, 2015-10)
      Purpose: This study aimed to describe the scope of accelerometry data collected internationally in adults and to obtain a consensus from measurement experts regarding the optimal strategies to harmonize international ...
