Muscle, Mobility, and Aging (SOMMA2)

Study of Muscle, Mobility and Aging: SOMMA2

NIH-funded research California Pacific Med Ctr Res Institute · NIH-11195674

This project looks for biological changes in muscle and blood that predict loss of strength, trouble with daily activities, dementia, or early death in older adults.

What this research studies

You would join a long-term effort that adds 650 older adults to a group already studied for muscle and mobility changes. Participants give blood, have muscle biopsies repeated over time, and complete tests of strength, fitness, and thinking. Researchers will study muscle energy production, DNA damage, oxidative stress, cell aging signals, and gene activity to see which changes match declines in power, fitness, or daily function. The goal is to find body-level signs that happen before disability, dementia, or death so future tests or treatments can target those pathways.

Who could benefit from this research

Good fit: Ideal candidates are older adults who can travel to San Francisco, undergo blood draws and repeat muscle biopsies, and participate in physical and cognitive testing.

Not a fit: People who cannot have muscle biopsies, already have advanced disability, or cannot attend repeated clinic visits are less likely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this work could help predict who is at higher risk for mobility loss or dementia and point to new treatments to keep older adults healthier and more independent.

How similar studies have performed: An earlier phase (SOMMA1) already linked muscle mitochondrial function to mobility decline, and SOMMA2 expands that work to more people and more biological pathways.
