Estimating energy expenditure in wildland fire fighters using a physical activity monitor
This study piloted the use of an electronic acitivity monitor (MTI AM 7164-1.2) as a tool estimating acivity (EE ACTkcal day(exp-1)) and total (EE TOT, kcal day(exp-1)) energy expenditure in wildland fire fighters during extended periods of wildland fire suppression. Ten Hot Shot fire fighters (9 men, 1 woman) volunteered to wear a MTI monitor during every work shift for 21 consecutive days. Summarizing whole-baody motion data each 1 min, the raw activity data (counts min-1) were transformed into units of kcal min-1, using a custom somputer program with standard conversion equations. EE TOT averaged (Mean+/-SD) 4768 +/- 478 kcal day-1, while EE act averaged 2585+/-406 kcal day-1, neither of which differed significantly (P=0.198 and 0.268, respectivaly) from literature values reported for Hot Shots using the double lebelad water technique. These data suggest that the electronic acitivity monitor provided reasonable estimates of EE in wildland fire fighters. This study should be verified, however, with a more complete validation methodology to ensure these findings.
