The Claim
In young and middle-aged adults, relative maximum muscle power (Pmax normalized to body mass) declines more steeply than absolute Pmax due to age-related increases in BMI, with an estimated decrease in relative Pmax of 0.9–1.5% per year, indicating that changes in body composition amplify the decline in functional muscle performance with age.
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.
As people in their younger and middle years get older, their muscle power relative to body weight drops faster than total muscle power—partly because BMI tends to go up, making it harder to stay strong for your size.
See the scientific wording
Relative maximum muscle power (Pmax normalized to body mass) declines more steeply than absolute Pmax in young and middle-aged adults due to age-related increases in BMI, with relative Pmax decreasing by 0.9–1.5% per year in these groups, highlighting the compounding effect of body composition changes on functional performance.
What the research says
1 studyThe study found that as people gain weight with age, their muscle power measured relative to body weight drops faster than their total muscle power, which supports the claim.
