DXA Body Composition Applications from Sarcopenia to Sport
Saturday, April 25, 2026, 2:45pm - 3:45pm Eastern Time (NY/USA)
Description and Objectives
This session will provide DXA technologists with a focused, practical framework for acquiring, analyzing, and reporting body composition data tailored to the needs of diverse clinical specialties. Participants will review primary DXA-derived body composition metrics—including appendicular lean mass (ALM), visceral adipose tissue (VAT), and fat mass index (FMI)—and learn how their clinical relevance differs across geriatrics, bariatrics, and sports medicine. The program will emphasize identification of the most appropriate body composition outputs for monitoring patient progress in metabolic risk assessment, eating disorder recovery, and athletic performance. In addition, the session will explore the clinical significance of regional versus total body composition measurements, enabling technologists to better support referring providers through accurate data acquisition, interpretation, and communication.
After attending this lecture, participants will be able to:
- Differentiate between the primary DXA metrics (such as ALM, VAT, and FMI) required by various specialties, including geriatrics, bariatrics, and sports medicine.
- Identify which body composition outputs are most relevant for tracking patient progress in metabolic risk assessment, eating disorder recovery, and athletic performance.
- Discuss the clinical significance of regional and total body composition data to better understand the diverse needs of referring providers.
Handouts

Jonathan Bennett, PhD
Epidemiology
University of Hawaiʻi Cancer Center
Dr. Jonathan Bennett's research focuses on the technical aspects of body composition assessment technologies and the relationships between body composition measures and disease risk. His PhD research identifies the qualities and capabilities of assessment technologies for the assessment of nutrition status. His current research identifies specific components of body composition and their role in disease prevention, risk, and/or progression. His studies range in populations from infants (0-5y) to older adults with functional decline, including specialized populations such as astronauts, athletes and patients with obesity or cancer. His current efforts focus on how targeting specific aspects of body composition can impact disease risk and treatment.
Dr. Bennett received his MSc in Kinesiology (California State University, Long Beach) and PhD in Nutrition (University of Hawai'i at Manoa) and is currently a fellow at the University of Hawai'i Cancer Center. His work has been recognized at national and international conferences and working groups; he also serves as a Body Composition expert for the International Atomic Energy Agency and is on the Scientific Advisory Board of the International Body Composition Symposium conference.
