How Exercise Quiets a Muscle-Wasting Inflammation Signal in Older Women
Graded Moderate — two human studies in older adults including a 48-week exercise intervention, though participant numbers are unreported and the mechanistic evidence comes from mice and cells.
This study suggests regular structured exercise may help lower inflammation tied to age-related muscle loss.
Scientists found a specific inflammation signal called CXCL2 that climbs as muscle loss gets worse with age. In older adults, higher levels tracked with weaker strength and worse mobility. A year of structured exercise sharply lowered this signal and improved strength, while non-exercisers kept declining.
