The day before the event, the participants completed a demographic questionnaire, and body composition was measured using bioelectrical impedance analysis (mBCA 525, Seca). The swimming event consisted of laps over a 1000-m course, for up to 6 hours, in water at 12.5 to 13 \u00b0C. <jats:inline-formula\/> was measured using an ingestible temperature sensor (e-Celsius, BodyCap) during and up to 1\u00a0hour after the swim. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> A total of 14 participants (38 [11]\u00a0y; N\u2009=\u200914, n\u2009=\u200911 males, n\u2009=\u20098 in swimming costume and n\u2009=\u20096 in wetsuit) were included. Before swimming, <jats:inline-formula\/> was 37.54 (0.39) \u00b0C. The participants swam for an average of 194.00 (101.94)\u00a0minutes, and mean <jats:inline-formula\/> when exiting the water was 35.21 (1.30) \u00b0C. The duration of continued cooling was 25 (17)\u00a0minutes with a minimum <jats:inline-formula\/> of 34.66 (1.26) \u00b0C. Higher body mass index (<jats:italic>r<\/jats:italic>\u2009=\u2009.595, <jats:italic>P<\/jats:italic>\u2009=\u2009.032) and fat mass (<jats:italic>r<\/jats:italic>\u2009=\u2009.655, <jats:italic>P<\/jats:italic>\u2009=\u2009.015) were associated with longer continued cooling, independent of wetsuit wear. Also, the rate of <jats:inline-formula\/> drop during swimming (\u22121.22 [1.27] \u00b0C\/h) was negatively correlated with the rate of <jats:inline-formula\/> gain after swimming (+1.65 [1.23] \u00b0C\/h, <jats:italic>r<\/jats:italic>\u2009=\u2009\u2212.682, <jats:italic>P<\/jats:italic>\u2009=\u2009.007). <jats:italic><jats:bold>Conclusion<\/jats:bold>:<\/jats:italic> Increased body mass index and fat mass were associated with <jats:inline-formula\/> continued cooling duration after prolonged outdoor cold-water swimming at 12.5 to 13 \u00b0C.
