Aim. The authors hypothesized that inconsistent SIgA response to exercise is caused by the different adaptative status of subjects to a cold environment. The purposes of the study were to examine whether moderate-intense exercise in a cold environment decreases SIgA and whether adaptation to a cold environment has any effect on SIgA. Methods. Young male skaters, short track (N=9) and inline (N=10VOC), participated in this study. All subjects cycled for 60 min at 65% VO2max in cold (ambient temperature: 5±1 °C, relative humidity 41±9%) and thermoneutral (ambient temperature: 21±1 °C, relative humidity 35±5%) conditions. Saliva samples were collected as follows: before and after 1hour of environmental exposure; immediately, 30-min, 60-min and 120-min after the exercise. Results and conclusion. Salivary SIgA and saliva flow rate decreased after the exercise in both groups only in thermoneutral conditions. The SIgA secretion rate did not decrease after moderate-high intensity exercise in a cold environment, and the SIgA response to exercise was not affected by the different adaptative status of subjects to the cold environment.
