We investigated core body temperature (CBT) during a graded exercise test (GXT) in comparison with gas exchange dynamics. Thirty-two active males performed a treadmill GXT (0.5 km/h increments every 30 seconds, 1.5% incline) until exhaustion. Gas exchange data and rectal temperature (T ) were contin...
