The Claim

Lower relative muscle power, measured as watts per kilogram of body weight during an upper row movement, is strongly associated with higher all-cause mortality in middle-aged and older adults aged 46 to 75 years. Individuals in the lowest quartile of relative muscle power have a 5.88-fold (95% CI: 2.28–15.17) higher risk of death in men and a 6.90-fold (95% CI: 1.61–29.58) higher risk in women compared to those in the highest quartile, after adjusting for age, waist-height ratio, and clinical comorbidities.

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.

In plain English

If middle-aged or older adults don't have much muscle power for their weight — like when pulling motions — they're much more likely to die earlier than those who are stronger, even after accounting for things like belly fat and health conditions.

1 study
  1. Study: Muscle Power Versus Strength as a Predictor of Mortality in Middle-Aged and Older Men and Women.

    The study found that people with less muscle power for their weight were much more likely to die during the study, and the numbers match exactly what the claim says.
