Mechanisms of Anabolic Resistance in Older Humans
Mayo Clinic
Summary
The purpose of this research is to understand how chronic inflammation affects muscle function and responses to exercise in older adults.
Description
Inflamed adipose tissue may contribute to blunted exercise response in skeletal muscle of older adults. The objective of this project is to evaluate a hypothesis that inflamed adipose secretes factors that activate inflammatory cascades in skeletal muscle, which may interfere with exercise-responsive molecular pathways and contribute to dysfunctional muscle phenotypes with aging. This project determine how adipose tissue influences skeletal muscle function and anabolic response to exercise in older adults. Young and older adults will complete studies to assess molecular response to acute exerc…
