Abstract
Fourteen men and 13 women firefighters walked on a treadmill and climbed a stair ergometer while wearing Goodyear welt stitched-soled and cement-soled leather boots. During treadmill exercise, significant (p < / = 0.05) decreases in VO2 (-4.5%), and VO2/kg (-4.6%), were observed in men for cement as compared to stitched soles. Significant decreases in VO2 (-4.8%), and VO2/kg (-4.0%) were observed in women. These decreases were seen despite the lack of difference in boot weight, a factor that has been shown to increase metabolic and respiratory variables. A significant (p < / = 0.05) gender effect was observed for VO2kg and HR. During stair ergometry, insignificant decreases of 1 - 3% were observed for VE, VO2, VCO2, VO2/kg, and HR in men and women for cement as compared to stitched soles. A significant (p < / = 0.05) gender effect was observed for VO2, VO2kg and HR.
