    • Effects of a 10-d Military Field Exercise on Body Composition, Physical Performance, and Muscle Cells in Men and Women 

      Vikmoen, Olav; Teien, Hilde Kristin; Tansø, Rita; Aandstad, Anders; Lander, Elise; Cumming, Kristoffer Toldnes; Ellefsen, Stian; Helkala, Kirsi Marjaana; Raastad, Truls (2024-04)
      Purpose: To investigate the effects of a demanding military field exercise on physical performance, body composition and muscle cellular outcomes in men and women. Methods: Ten men (20.5 ± 0.5 years) and 8 women ...

    • Effects of exercise mode, energy, and macronutrientinterventions on inflammation during military training 

      Pasiakos, Stefan M; Margolis, Lee M; Murphy, Nancy E; McClung, Holy L; Martini, Svein; Gundersen, Yngvar; Castellani, John W.; Karl, James P.; Teien, Hilde Kristin; Madslien, Elisabeth Henie; Stenberg, Pål H.; Young, Andrew J.; Montain, Scott J; McClung, James P (2016)
      Load carriage (LC) exercise may exacerbate inflammation during training. Nutritional supplementation may mitigate this response by sparing endogenous carbohydrate stores, enhancing glycogen repletion, and attenuating ...

    • Effects of Supplemental Energy on Protein Balance during 4-d Arctic Military Training 

      Margolis, Lee M; Murphy, Nancy E; Martini, Svein; Gundersen, Yngvar; Castellani, John W.; Karl, James P.; Carrigan, Christopher T; Teien, Hilde Kristin; Madslien, Elisabeth Henie; Montain, Scott J; Pasiakos, Stefan M (2016)
      Soldiers often experience negative energy balance during military operations that diminish whole-body protein retention, even when dietary protein is consumed within recommended levels (1.5-2.0 g[middle dot]kg-1[middle ...

    • Energy deficit increases hepcidin and exacerbates declines in dietary iron absorption following strenuous physical activity: a randomized-controlled cross-over trial 

      Hennigar, Stephen R.; McClung, James P.; Hatch-McChesney, Adrienne; Allen, Jillian T.; Wilson, Marques A.; Carrigan, Christopher T.; Murphy, Nancy E.; Teien, Hilde Kristin; Martini, Svein; Gwin, Jess A.; Karl, J. Philip; Margolis, Lee M.; Pasiakos, Stefan M. (2020-11-12)
      Background Strenuous physical activity promotes inflammation and depletes muscle glycogen, which may increase the iron regulatory hormone hepcidin. Hepcidin reduces dietary iron absorption and may contribute to declines ...

    • Introduction: Training is more important than technology (for performance in the cold) 

      Friedl, Karl E.; Hasselstrom, Henriette; Kingma, Boris R.M.; Norheim, Arne Johan; Ojanen, Tommi; Sullivan-Kwantes, Wendy; Teien, Hilde Kristin; White, Graham (2023-07-27)
      After more than 50 years of studying soldiers in the cold, we are well past the phase of defining the unique problems; the research requirements are known but the solutions have been slow in coming. This requires iterative ...
