Program Description

This session will begin with a discussion of the importance of muscle health, the role of nutrition, specifically dietary protein, and factors, such as age and exercise, which may affect digestion and absorption of protein sources to impact muscle health.  The presenters will focus on findings from recently completed studies that investigate the role of exercise, leucine, amino acid blends and blends of proteins on skeletal muscle myofibrillar protein synthesis and amino acid transporter expression in young and older subjects.  The session will include an emphasis on methods and mechanisms and conclude with a discussion of practical outcomes and clinical implications.  A panel discussion with audience engagement will be included.

Learning Objectives

At the end of this session, attendees will be able to:

• Discuss the role of nutrition and specifically dietary protein in muscle health;
• Review recent findings on the effects of post-exercise ingestion of leucine and protein blends on muscle protein synthesis and growth.
