ABSTRACT
This study investigated physiological responses and performance during three separate exercise challenges (Parts I, II, and III) with wildland firefighting work clothing ensemble (boots and coveralls) and a 20.4â¯kg backpack in four conditions U-EX (no pack, exercise clothing); L-EX (pack, exercise clothing); U-W (no pack, work clothing); and, L-W (pack and work clothing). Part I consisted of randomly-ordered graded exercise tests, on separate days, in U-EX, L-EX and L-W conditions. Part II consisted of randomly-ordered bouts of sub-maximal treadmill exercise in the four conditions. In Part III, subjects completed, in random-order on separate days, 4.83â¯km Pack Tests in L-EX or L-W conditions. In Part I, peak oxygen uptake was reduced (pâ¯<â¯.05) in L-W. In Part II, mass-specific oxygen uptake was significantly higher in both work clothing conditions. In Part III, Pack Test time was slower (pâ¯<â¯.05) in L-W. These results demonstrate the negative impact of work clothing and load carriage on physiological responses to exercise and performance.
