The Claim

In human populations, assessing relative muscle power improves the accuracy of all-cause mortality risk prediction models beyond conventional risk factors such as age, waist-height ratio, and medical history, with a reported increase in the C-index by 0.0133 in men and 0.0227 in women, and a 40–45% continuous net reclassification improvement, indicating that muscle power provides additional prognostic value in clinical risk assessment.

In plain English

Measuring how powerful your muscles are—relative to your size—might help doctors better predict your risk of dying from any cause, even after considering things like age, belly fat, and medical history. It seems to be especially helpful for women.

Assessing relative muscle power improves the accuracy of all-cause mortality risk prediction models beyond conventional risk factors such as age, waist-height ratio, and medical history, with a 0.0133 increase in the C-index in men and 0.0227 in women, and a 40–45% continuous net reclassification improvement, indicating that muscle power adds meaningful prognostic value in clinical risk assessment.

What the research says

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

    The study shows that muscle power is a better predictor of death risk than muscle strength, but it doesn't prove that adding it to standard health checks improves predictions by the exact amounts claimed.
