The Claim
In older adults, Black individuals experience approximately 28% greater annualized leg strength decline than White individuals, independent of differences in muscle mass.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among older adults, Black individuals lose leg strength at a rate 28% faster per year than White individuals, even when accounting for differences in muscle mass.
See the scientific wording
In older adults, Black individuals experience approximately 28% greater annualized leg strength decline than White individuals, independent of differences in muscle mass, suggesting racial disparities in age-related muscle function loss.
In older adults, the connections between nerves and muscles become less stable over time, causing nerves to lose their ability to fully activate muscle fibers. This leads to a faster drop in strength than would be expected from muscle loss alone, and this process happens more rapidly in some individuals.
What the research says
1 studyThe study found that older Black adults lost leg strength about 28% faster than older White adults, even though both groups lost muscle mass at the same slow rate — meaning something else, like muscle quality or nerve function, might be causing the bigger strength drop in Black adults.
