exercise in a temperate environment. 7 In contrast to our findings, these studies 7 , 29 observed classic signs of heat acclimation (eg, reduced HR, greater body mass loss). Differences in intervention length, training duration, and participants’ training status may explain the conflicting results. 7

). The physiological characteristics that could potentially influence IL-6 and hepcidin were not different between the dietary groups at the baseline, nor were the total energy expenditure (6,155 kcal/day), body mass loss (2.7 kg), and energy deficit (∼55%) at the end of the march. Samples were collected
