Treatment and study plan

Assessment of resting energy expenditure

Device

We will assess the resting metabolic rate and respiratory exchange ratio of twenty healthy adults, with every metabolic cart on two days in the morning. The assessment will last 30 minutes on each metabolic cart, with 15-minute breaks between measurements. The order of the metabolic carts will be randomly selected and replicated the second day.
