Notes: Minimum = minimum value prior the CIVD. Maximum = maximum value during the CIVD. Onset time = time of the minimum value − start time of the cold immersion. Peak time = time of the minimum value − time of the maximum value. Average = mean values of the last 35 min of the cold immersion. Amplitude = maximum − minimum temperature.
