All inferences were calculated comparing the water immersion strategy with the CTRL condition. mRR: mean R-R intervals; ln rMSSD: normal logarithm of the square root of the mean of the sum of the squares of differences between adjacent normal R–R intervals; SD1: instantaneous beat-to-beat variability; SD2: continuous beat-to-beat variability.
