dc.description.abstract A great deal of research has been done to assess the effects of exercise intensity and duration on excess post-exercise oxygen consumption (EPOC). But the effects of an elevated core temperature (Tc) post-exercise have not been directly examined. To assess the effects of an elevated Tc on EPOC, eight healthy, active male subjects (27.5 ± 6.1 years) underwent two 45 minute exercise trials at =70% VO2max in an environmental chamber (36 °C / 10% RH) followed by a 45 minute recovery in either the environmental chamber (42 °C / 10% RH) wearing insulating clothing (HC), or in the ambient conditions of the testing lab (22 °C / 42% RH) without any additional clothing (AM). Oxygen consumption (V02), minute ventilation (VE), heart rate (HR), and rectal temperature (Tc) were recorded pre-, exercise, and post- during both trials. Subjects were monitored postexercise for 45 minutes. EPOC was determined by subtracting pre-trial V02 from the recovery V02 until the difference between the values equaled zero or until 45 minutes had elapsed. Within 25 minutes post-exercise, V02 during the AM recovery had returned to near resting levels (p = 0.146), while V02 during the HC recovery remained significantly elevated for at least 45 minutes (p = 0.027). Given that V02 remained significantly elevated through 45 minutes of recovery, and that all other measured variables (HR, VE, and respiratory exchange ratio) were significantly affected during the HC recovery, it is clear that an elevated Tc has an effect on EPOC.
