Objective: Determine serum lipid and general health/fitness alterations following a 5-month
wildfire suppression season. Methods: We recruited 100 wildland firefighters (WLFFs) to a 5-
month pre-to post-season observational study. Nude body mass, blood pressure (BP), grip
strength, and steptest heart rate (HR) were recorded. Blood samples were collected for lipid
panel analysis (total cholesterol, high density lipoproteins (HDL)-cholesterol, low density
lipoproteins-cholesterol, very low density lipoproteinscholesterol, triglycerides, triglyceride …

… However maladaptive seasonal responses in adiposity and blood lipid profiles have
been noted. PURPOSE: To determine changes in clinical health metrics and serum lipids
resulting from 5 months of seasonal wildland fire suppression. METHODS: We recruited
wildland firefighters (WLFF), (n=100, 92 males, 8 females) from seven crews (5 Hotshot
crews, 1 Initial Attack crew) based in MT and CA. After an overnight fast, nude body mass,
blood pressure (BP), grip strength, and step test heart rate (HR) (~VO2=20.7 mL/kg/min) …
