CI, Confidence Interval; Inc, increase temperature; SD, Standard Deviation, Total exercise, from warm-up to 20 min post-exercise.
Range [Min to Max]; Individually measured temperatures for all participants in each group.
A sample size below 15 is due to the occurrence of missing values due to discontinuation of the treadmill protocol.
