Review Recasts Age-Related Strength Loss as Whole Motor-System Decline, Not Just Muscle

Summary
A new review argues age-related strength decline reflects deterioration across the brain, spinal cord and nerves—not only shrinking muscle mass.
The authors say similar muscle size can produce very different strength and mobility because aging also weakens nerve-muscle signaling, reaction time and proprioception.
That broader view may explain why treatments that add muscle do not always deliver matching gains in strength or daily function, while exercise can help even with little muscle growth.
For older adults, the review points to 2 to 3 weekly resistance sessions plus adequate protein and balance or coordination work such as single-leg stands, direction changes or dancing.
The paper is a research review rather than a new trial, making the case that healthy aging should target the entire motor system instead of muscle mass alone.
