How much does core body temperature increase during exercise?

Given that mechanical efficiency varies from 20 to 25%, most of the metabolic energy converted to produce movement is released as heat. For example, exercise performed at 80 to 90% of maximal aerobic capacity (VO2 max) could increase core temperature by 1°C every 5 to 8 minutes if heat was not dissipated.

Does exercise raise core temperature?

Both the exercise itself and the air temperature and humidity can increase your core body temperature. To help cool itself, your body sends more blood to circulate through your skin. This leaves less blood for your muscles, which in turn increases your heart rate.
