The heat condition is the intervention. Personal protective equipment will be used to create the rapid heat stress condition, resulting in a rapid rise in core temperature. This will be in combination with the physiological heat produced by the treadmill protocol.

The gradual heat condition is the control. Physiological heat will be produced by exercise on a treadmill, and light exercise clothing will help moderate the rise in core temperature.
