SP - e91 EP - e94 VL - 61 IS - 3 N2 - OBJECTIVE: The purpose of this study was to evaluate pre- and post-season measures of body composition, skeletal muscle, and blood parameters/liver lipid in wildland firefighters (WLFF) over the fire season.

METHODS: Alaskan WLFF (N = 27) crews were evaluated pre and post wildfire season, which included 63 ± 10 operational days. Body composition, thigh muscle area and liver lipid were quantified using dual energy x-ray absorptiometry and MRI, respectively. Blood metabolic and lipid panels were also collected and analyzed.

RESULTS: Total body, fat, and visceral fat mass increased from pre to post season (p < 0.05). Total cholesterol, LDL and total globulin also increased (p < 0.05). There was a trend (p = 0.06) towards an increase in IHL.

CONCLUSIONS: The observed maladaptive changes in adipose tissue, blood lipids and hepatic function may reflect adaptations/consequences to occupational demands/conditions and warrant evaluation of appropriate countermeasures.
