The Nutrition, Exercise Physiology, and Sarcopenia Laboratory conducts studies aimed at the identification, evaluation, and understanding of nutritional and physical activity interventions that possess anabolic properties in skeletal muscle and have the potential to prevent or reverse impaired motor performance and/or physical dysfunction in older adults.
1. Investigate the nutritional and activity-related mediators of skeletal muscle atrophy associated with advancing age in animal and human studies.
2. Evaluate the chronic effects of dietary proteins/amino acids and physical activity/inactivity on changes in skeletal muscle structure and function and physical functioning in at-risk older individuals.
Roger A. Fielding, Ph.D., Laboratory Director
Research focus: Impact of exercise and physical activity on successful human aging; skeletal muscle alterations with advancing age in disabled and non-disabled populations; and age-related alterations in the control of skeletal muscle protein turnover
Donato Americo Rivas, Ph.D.
Research focus: The role of substrates on cellular signaling pathways controlling skeletal muscle metabolism and growth; and how nutrition, aging and exercise contribute to alterations in skeletal muscle energy homoeostasis
Michael Lustgarten, Ph.D.
Research focus: The role of the gut microbiome and serum metabolome on muscle mass and function in older adults
Kieran F. Reid, Ph.D., M.P.H
Research focus: Skeletal muscle performance and human aging; assessment of mobility and cognition; exercise and nutritional interventions to preserve independence with advancing age; translational science to promote healthy aging in underserved populations
