Subjects were randomly assigned to one of two 9-day heat acclimation groups. The first group (WARM; n\u2009=\u200910) cycled for 2\u2009hours at 50\u2009W in 34.4\u2009\u00b0C water, while the second group (HOT; n\u2009=\u200910) cycled for 1\u00a0hour against minimal resistance in 36.7\u2009\u00b0C water. Following acclimation, TTE was tested by underwater cycling (30\u2009W) in 35.8\u2009\u00b0C, 37.2\u2009\u00b0C, and 38.6\u2009\u00b0C water.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Throughout acclimation, the rate of core temperature rise in the first 30\u2009minutes of exercise increased (P\u2009=\u2009.02), but the maximum core temperature reached was not different for either group. Time to exhaustion (TTE) was reduced, and the rate of core temperature rise during performance testing increased (both P\u2009&amp;lt;\u2009.001) with increasing water temperature but was not different between groups. Core temperature and HR increased throughout performance testing in each water condition and were lower in the HOT compared to the WARM acclimation group (all P\u2009&amp;lt;\u2009.05) with the exception of core temperature in the 37.2\u2009\u00b0C condition.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Underwater exercise performance did not differ between the two acclimation strategies. This study suggests that passive acclimation to a higher water temperature may improve thermoregulatory and cardiovascular responses to exercise in warm water.
