Researcher: Grant M. Tinsley, Ph.D.
Title: Assistant Professor of Exercise Physiology
Laboratory: Room 114, Energy Balance & Body Composition Laboratory
Overview
Dr. Tinsley is the Director of the Energy Balance & Body Composition Laboratory in the Department of Kinesiology & Sport Management at Texas Tech University. His lab group studies the impact of nutrition, exercise, and supplementation on human body composition, exercise performance, and health. Two particular research interests are evaluating intermittent fasting programs in active individuals and examining body composition assessment methodology, including validity and reliability testing of novel assessment techniques.

- Muscle cross-sectional area, thickness, and quality
- Visceral fat estimation
- Fluid analysis
- Total body water
- Intracellular water
- Extracellular water
- Automated anthropometric analysis
- Total and segmental volumes
- Circumferences and lengths of virtually any body segment
- Bioelectrical parameter analysis
- Resistance, reactance, and impedance
- Phase angle
- Resting metabolic rate assessment
- Substrate oxidation assessment
