Abstract This study compared physiological responses and total work tolerance time following forearm submersion (FS) or leg submersion (LS) in cool water, after performing work in a hot environment while wearing firefighting protective clothing (FPC). Participants walked at 3.5 mph on a treadmill in a hot environment until a rectal temperature of 38.5░C was reached. They were then subjected to one of two peripheral cooling interventions, in a counterbalanced order. Forearms or lower legs were submerged in water (16.9▒0.8░C) for 20 min, followed by a work tolerance trial. Findings are discussed. There was little difference between FS and LS for physiological measures. Despite a lack of statistical significance a 5-min (24%) increase was found for work tolerance time following LS.
