Official title: Neural mechanisms of age-related weakness

Funded at Ohio University Athens · NIH-11380730 · Data updated 2026-11-12

Researchers are studying why older adults lose muscle strength and how brain and nerve activity contribute, with findings that could lead to better ways to keep people independent.

Who could benefit from this research

Could help

Older adults experiencing or at risk for age-related muscle weakness and mobility limitations.

Less likely to help

Results may not directly benefit younger individuals or those without age-related weakness.

What this research studies

This project looks at why aging causes weakness by linking neural activity to muscle function in older adults and tests potential treatment strategies in both humans and animals. It includes a longitudinal human study to see if neural hypoexcitability predicts future strength loss, plus supporting rodent experiments to explore mechanisms and interventions. The work aims to identify targets that could be used to improve strength and mobility in older people, potentially leading to new therapies or exercise approaches. Results could inform personalized plans to maintain independence as people age.

Why it matters

Potential benefit: If successful, the research could identify neural factors contributing to weakness and guide new or refined therapies to preserve strength and independence in older adults.

How similar studies have gone: Preliminary evidence suggests a link between neural activation and age-related weakness, with translational studies showing promise in animals and humans.
