  Device-based measurement of lifestyle-related variables from the hip 

  Weitz, Marc (Doctoral thesis; Doktorgradsavhandling, 2025-06-17)

  Physical activity epidemiology is the study of patterns, risks, and effects of physical activity within populations. It plays a crucial role in understanding how physical activity influences health outcomes, such as reducing the risk of chronic diseases like cardiovascular disease, diabetes, and obesity. An important prerequisite is the accurate measurement of physical activity, which can be assessed ...

  Automatic time in bed detection from hip-worn accelerometers for large epidemiological studies: The Tromsø Study 

  Weitz, Marc; Syed, Shaheen; Hopstock, Laila Arnesdatter; Morseth, Bente; Henriksen, André; Horsch, Alexander (Journal article; Tidsskriftartikkel, 2025-05-06)

  Accelerometers are frequently used to assess physical activity in large epidemiological studies. They can monitor movement patterns and cycles over several days under free-living conditions and are usually either worn on the wrist or the hip. While wrist-worn accelerometers have been frequently used to additionally assess sleep and time in bed behavior, hip-worn accelerometers have been widely ...

  Antarctic glaciers export carbon-stabilised iron(II)-rich particles to the surface Southern Ocean 

  Jones, Rhiannon L.; Hawkings, Jonathan Robert; Meredith, Michael P.; Lohan, Maeve C.; Moore, Oliver W.; Sherrell, Robert M.; Fitzsimmons, Jessica N.; Kazemian, Majid; Araki, Tohru; Kaulich, Burkhard; Annett, Amber L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2025-05-30)

  Iron is an essential micronutrient for phytoplankton and plays an integral role in the marine carbon cycle. The supply and bioavailability of iron are therefore important modulators of climate over glacial-interglacial cycles. Inputs of iron from the Antarctic continental shelf alleviate iron limitation in the Southern Ocean, driving hotspots of productivity. Glacial meltwater fluxes can deliver ...

  Nature guiding and relational perspectives on sustainability: Exploring practices of care and local knowledge enactments in Northern Troms, Norway 

  Omma, Frida Marie (Doctoral thesis; Doktorgradsavhandling, 2025-06-19)

  Nature-based tourism is a significant industry in Norway and globally, contributing economically to local communities. However, it can negatively impact local nature and culture. Despite a trend towards sustainable tourism development, sustainability has been criticised for prioritising economic interests. Climate change and biodiversity loss further threaten the foundation of nature-based tourism, ...

  The influence of menstrual cycle phase on performance-determining variables, acute training responses and recovery in endurance-trained athletes 

  Taylor, Madison Y. (Doctoral thesis; Doktorgradsavhandling, 2025-06-12)

  <p><i>Aims:</i> This thesis aimed to investigate the influence of MC phase on endurance performance-determining variables (Paper I), the acute responses to low- and high-intensity training sessions (LIT/HIT) (Paper II), and sleep and recovery following exercise (Paper III). It also aimed to assess the accuracy of a modified MC tracking system (2-step method) for detecting subtle menstrual disturbances ...
