Measuring heat production to determine metabolic rate = ?
Mini Test Study Guide
Direct calorimetry:
- Measuring heat production to determine metabolic rate.
Resting energy use: Basal metabolic rate → typically taken in a darkened room upon waking after eight hours of sleep, 12 hours of fasting to ensure that the digestive system is inactive, and with the subject resting in a reclined position)
