What was done
This is a narrative review outlining a working hypothesis regarding lower extremity peak skeletal muscle power as a key determinant linking age-related physical impairments to functional limitations and disability.
What was found
The abstract reports conceptual findings without quantitative data: muscle power declines earlier and more rapidly with advancing age compared with muscle strength, and peak muscle power serves as an important predictor of functional limitations in older adults.
Why it matters
It highlights that interventions targeting mobility in older adults should potentially focus on muscle power generation rather than absolute muscle strength alone.
Limits
The abstract contains no primary quantitative data, sample sizes, or systematic review methodology, representing an expert perspective and conceptual framework.
