Cardiovascular and thermal strain during 3–4 days of a metabolically demanding cold‑weather military operation
Castellani, John W.; Spitz, Marissa G; Karis, Anthony J.; Martini, Svein; Young, Andrew J; Margolis, Lee M; Karl, J Philip; Murphy, Nancy E; Xu, Xiaojiang; Montain, Scott J; Bohn, Jamie A; Teien, Hilde Kristin; Stenberg, Pål H.; Gundersen, Yngvar; Pasiakos, Stefan M (2017)Background Cardiovascular (CV) and thermal responses to metabolically demanding multi-day military operations in extreme cold-weather environments are not well described. Characterization of these operations will provide ... -
Changes in intestinal microbiota composition and metabolism coincide with increased intestinal permeability in young adults under prolonged physiologic stress
Karl, J Philip; Margolis, Lee M; Madslien, Elisabeth Henie; Murphy, Nancy E; Castellani, John W.; Gundersen, Yngvar; Hoke, Allison V; Levangie, Michael W; Kumar, Raina; Chakraborty, Nabarun; Gautam, Aarti; Hammamieh, Rasha; Martini, Svein; Montain, Scott J; Pasiakos, Stefan M (2017)The magnitude, temporal dynamics, and physiological effects of intestinal microbiome responses to physiological stress are poorly characterized. This study used a systems biology approach and a multiple-stressor military ... -
Effects of a 7-days military training exercise on inflammatory biomarkers, serum hepcidin, and iron status
McClung, James P; Martini, Svein; Murphy, Nancy E; Montain, Scott J; Margolis, Lee M; Thrane, Ingjerd; Spitz, Marissa G; Blatny, Janet Martha; Young, Andrew J; Gundersen, Yngvar; Pasiakos, Stefan M (2013)Background Hepcidin, a peptide that is released into the blood in response to inflammation, prevents cellular iron export and results in declines in iron status. Elevated serum and urinary levels of hepcidin have been ... -
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 ... -
Heat stress in chemical protective clothing: porosity and vapour resistance
Havenith, George; den Hartog, Emiel; Martini, Svein (2011)Heat strain in chemical protective clothing is an important factor in industrial and military practice. Various improvements to the clothing to alleviate strain while maintaining protection have been attempted. More recently, ... -
Human performance research for military operations in extreme cold environments
Sullivan-Kwantes, Wendy; Haman, Francois; Kingma, Boris R.M.; Martini, Svein; Gautier-Wong, Emilie; Chen, Kong Y.; Friedl, Karl E. (2020)Objectives Soldier performance in the Arctic depends on planning and training, protective equipment, and human physiological limits. The purpose of this review was to highlight the span of current research on enhancing ... -
Military training elicits marked increases in plasmametabolomic signatures of energy metabolism, lipolysis,fatty acid oxidation, and ketogenesis
Karl, J Philip; Margolis, Lee M.; Murphy, Nancy E.; Carrigan, Christopher T; Castellani, John W.; Madslien, Elisabeth Henie; Teien, Hilde Kristin; Martini, Svein; Montain, Scott J.; Pasiakos, Stefan M (2017)Military training studies provide unique insight into metabolic responses to extreme physiologic stress induced by multiple stressor environments, and the impacts of nutrition in mediating these responses. Advances in ...
