      SUMMARY Demographic data indicate tripling the worlds's population 60 years or older bt the year 2050, while recent reports show that preventable, non-communicable diseases are on the rise and now account for 60% of all ...

    • Cardiorespiratory Reference Data in Older Adults: The Generation 100 Study. 

      Stensvold, Dorthe; Bucher Sandbakk, Silvana; Viken, Hallgeir; Zisko, Nina; Reitlo, Line Skarsem; Nauman, Javaid; Gaustad, Svein Erik; Hassel, Erlend; Moufack, Marcel; Brønstad, Eivind; Aspvik, Nils Petter; Malmo, Vegard; Steinshamn, Sigurd Loe; Støylen, Asbjørn; Anderssen, Sigmund Alfred; Helbostad, Jorunn L.; Rognmo, Øivind; Wisløff, Ulrik (Journal article; Peer reviewed, 2017)
      Purpose: Cardiorespiratory fitness (CRF) is regarded a clinical vital sign, and accurate reference values for all age groups are essential. Little data exist on CRF and cardiorespiratory function in older adults. The aim ...

    • Correlates of objectively measured physical activity among norwegian older adults: The Generation 100 Study 

      Viken, Hallgeir; Aspvik, Nils Petter; Ingebrigtsen, Jan Erik; Zisko, Nina; Wisløff, Ulrik; Stensvold, Dorthe (Journal article; Peer reviewed, 2016)
      The aim of this study was to identify how demographics, physical activity (PA) history, and environmental and biological correlates are associated with objectively measured PA among older adults. PA was assessed objectively ...

    • Do weather changes influence physical activity level among older adults? – The Generation 100 study 

      Aspvik, Nils Petter; Viken, Hallgeir; Ingebrigtsen, Jan Erik; Zisko, Nina; Mehus, Ingar; Wisløff, Ulrik; Stensvold, Dorthe (Journal article; Peer reviewed, 2018)
      Introduction Understanding how individual and environmental factors impact physical activity (PA) level is important when building strategies to improve PA of older adults. No studies have examined how hour-to-hour weather ...
