Understanding how aging and exercise affect fat within muscles

Effects of aging and exercise training on intermuscular adipose tissue (IMAT) in MoTrPAC

NIH-funded research University of Colorado Denver · NIH-11115647

This project looks at how fat marbled within our muscles changes with age and exercise, and how it might contribute to conditions like type 2 diabetes and muscle weakness.

What this research studies

We are exploring how fat found within skeletal muscles, called IMAT, might lead to decreased muscle sensitivity to insulin and muscle loss as we get older. Our goal is to understand if aging causes IMAT to release certain substances that harm muscle health, and if exercise can help reduce these harmful effects. By clarifying these connections, we hope to find new ways to improve muscle mass, strength, and insulin sensitivity in older adults. This work could help develop better strategies to prevent or manage age-related type 2 diabetes and sarcopenia.

Who could benefit from this research

Good fit: This research is relevant for older adults concerned about age-related muscle weakness, loss of muscle mass, or the risk of developing type 2 diabetes.

Not a fit: Patients who are not experiencing age-related muscle changes or type 2 diabetes may not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to new interventions that modify muscle fat to improve muscle health and reduce the risk of type 2 diabetes and sarcopenia in older individuals.

How similar studies have performed: While the role of IMAT in age-related conditions is recognized, this specific focus on fibronectin and myostatin secretion and cellular composition represents a novel approach to understanding its mechanisms.
