Summary

The investigators want to understand the impact of the body losing and gaining water on brain function. Participants will restrict fluids consumed and exercise to lose 5% of body mass. Participants will then be provided fluid equal to the volume lost to consume over 2 hours (recovery). A series of brain function tests will be performed at baseline, following weight loss, and following recovery.

Detailed description

A baseline series of brain function tests will be performed. Following this, participants will complete a 24 hour fluid and water rich food restriction on the day proceeding testing. Participants will then complete moderate to high intensity exercise in a hot/humid room to achieve 5% body mass loss. Once baseline core body temperature returns to baseline levels, the series of brain function tests will be performed. Participants will then consume a sports drink equal to the volume of sweat lost over the course of a 2 hour recover period. Following this, he series of brain function tests will be performed.
