The FAC represents a strategic interdisciplinary alliance between the Muscle Mechanics and Metabolomics Laboratory, the Laboratory of Exercise Physiology and Physical Performance and the Health and Disability Research Institute at Boston University and the Nutrition, Exercise Physiology and Sarcopenia Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University. The core provides standardized, state-of-the-art technologies to measure muscle performance, functional limitations, and disability in human and animal studies for OAIC’s pilot and exploratory projects and for several OAIC related projects funded through other sources.

Dr. Fielding is an internationally known researcher who studies the underlying mechanisms contributing to the age-associated decline in skeletal muscle mass, the resultant impact on function, and the potential role of exercise and physical activity on attenuating this process. Dr. Fielding has a strong record of NIH funding and oversaw the development of the interventions for the LIFE (Lifestyle Interventions for Elders) Pilot study and served as the Chair of the LIFE Intervention and Operations Committee. He also is a co-investigator and chair of the Body Composition Analysis committee for the NIA-funded “Calerie” trial.
