Moisture control is a primary concern. Crewmembers will contribute moisture to the cabin environment in the form of sweat while exercising. The effects of continuous aerobic exercise for improving and maintaining aerobic capacity is well characterized. Likewise, evidence suggests that high intensity interval exercise for shorter durations is also effective in building and maintaining aerobic capacity.<\/jats:p>\n<jats:p>\n<jats:bold>METHODS:<\/jats:bold> On separate days, measures of sweat and respiratory responses were made for continuous (30\u2009min of steady state exercise at \u223c75% of aerobic capacity) and two interval (4\u2009\u00d7\u20094\u2009min, 8\u2009\u00d7\u200930\u2009s) exercise protocols.<\/jats:p>\n<jats:p>\n<jats:bold>RESULTS:<\/jats:bold> We observed that the 4-min and 30-s interval protocols produce 16% and 66% less metabolic water loss vs. the continuous exercise protocol, respectively. These responses were highly correlated with the amount of work performed (R<jats:sup>2<\/jats:sup> = 0.81) and the amount of energy expenditure (R<jats:sup>2<\/jats:sup> = 0.83) during exercise.<\/jats:p>\n<jats:p>\n<jats:bold>DISCUSSION:<\/jats:bold> These results suggest that interval exercise may be a useful alternative to continuous aerobic exercise when metabolic water production is an environmental concern. The results may inform the choices of aerobic exercise countermeasure protocols for use in deep space exploration.<\/jats:p>\n<jats:p>\n<jats:bold>Ryder JW, Crowell JB, Song HJ, Ewert M. <jats:italic>Sweat production during continuous and interval aerobic exercise<\/jats:italic>.
