Trial Summary
Trial Overview
Inclusion Criteria
The purpose of the APEX study is to determine whether carbohydrate-electrolyte beverage
intake promotes fluid balance during exercise in the heat compared with water or placebo
intake.

Exercise in the heat has large effects on cardiovascular strain, the ability to regulate
core body temperature, and performance because of an increase in the reliance on body fluid
distribution to the skin to maintain adequate sweat rates and heat dissipation.
Carbohydrate-electrolyte beverage intake during exercise in the heat may improve fluid
balance and subsequent physical performance.

The participants will be assigned each arm in a randomized, counterbalanced, cross-over
fashion separated by at least 2 weeks. Participants will be placed in a heated environment
for the duration of the exercise intervention.

Inclusion Criteria:

- Males aged 18-35 years

- Healthy (No uncontrolled disease)

Exclusion Criteria:

- No medications that influence fluid balance

- No uncontrolled disease
