APS Annual Meeting at Experimental Biology

Nutrition and Skeletal Muscle: The Role of Macronutrients Beyond Energy

Symposium — Friday, April 30, 2021 — 2:00 PM - 3:30 PM — Virtual Session, Room APS-8
Nutrition Physiology Interest Group — Chair: Joe T Brozinick — Co-Chair: Tracy G Anthony

Skeletal muscle accounts for approximately 40% of total body mass and is influenced by environmental changes such as diet and physical activity levels.  A reduction in skeletal muscle mass and metabolic function can have detrimental effects on overall health and is a major contributing factor to the onset of chronic diseases such as obesity, diabetes, and cardiovascular disease. Loss of muscle mass and subsequent physical function not only places individual at greater risk of chronic disease but can lead to frailty and reduced quality of life as we age.  Nutritional strategies that improve skeletal muscle metabolic function could have a major impact on the development of chronic disease and, in the long-term, improve quality of life.  Therefore, the objective of this symposium is to present information related to the role of macronutrient intake on skeletal muscle health.
