The BCM Lab utilizes measures of muscle mass, muscle quality, and protein and energy metabolism to improve our understanding of the interactions between disease, illness and aging and nutritional status. The primary goal for the BCM Lab is to more effectively identify and monitor poor muscle health as a key feature of clinical malnutrition in hospital and outpatient settings and develop optimal interprofessional management strategies to improve nutrition status and health outcomes in individuals with chronic diseases such as heart failure and cancer, and in those undergoing hospitalization for acute illness or injury.



Bioimpedance Spectroscopy (BIS)

Measures: intracellular water; extracellular water; fat-free mass; and other markers of nutritional status

Ultrasound (US)

Measures: Quadriceps and biceps muscle thickness and muscle quality

Dual Energy X-ray Absorptiometry (DXA)

Measures: 1) Whole body lean soft tissue and fat mass 2) Whole body, hip and spine bone mineral density


Indirect Calorimetry (IC)

Measures: Resting Energy Expenditure (REE)

Doubly Labelled Water (DLW)

Measures: Total Daily Energy Expenditure (TDEE)
