Abstract

The purpose of this study was to examine the pattern of urinary protein excretion induced by three consecutive days of wildland firefighting. Eighteen male active duty military personnel were served as the participants. All testing consisting of three consecutive days was conducted at a Northwestern USA fire camp. All participants consumed military-based foods containing 2620-2864 kcal/day. The work activity was evaluated with an accelerometer in association with body weight and hydration markers over the experimental period. Urinary samples were collected at pre- and post-workshift of the Days 1 and 3 to assess glomerular and tubular protein excretion (total protein, albumin, β2-microglobulin, N-acetyl-β-D-glucosaminidase and creatinine). The urinary levels of glomerular and tubular protein were not significantly different. The main findings of the present study indicate that similar alterations of urinary protein composition can be observed, which appears to be dependent on intensity rather than total work output.
