The Claim
In adults aged 46 to 75 years, relative muscle power is a stronger predictor of all-cause mortality than relative muscle strength, as demonstrated by higher hazard ratios comparing the lowest versus highest quartiles and greater improvement in risk prediction model performance when muscle power is added compared to muscle strength.
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.
For middle-aged and older adults, how fast your muscles can generate power might be a better sign of how long you'll live than how strong they are — especially in men.
See the scientific wording
Relative muscle power is a stronger predictor of all-cause mortality than relative muscle strength in adults aged 46 to 75 years, as evidenced by significantly higher hazard ratios and greater improvement in risk prediction models. The hazard ratio for mortality in the lowest vs highest quartile was 5.88 for muscle power in men versus 1.62 for muscle strength, and the C-index improvement from adding muscle power to risk models was 0.0133 in men and 0.0227 in women, compared to 0.0023 and 0.0114 for strength.
What the research says
1 studyStudy: Muscle Power Versus Strength as a Predictor of Mortality in Middle-Aged and Older Men and Women.
The study shows that how fast someone can use their muscles (power) predicts death risk better than how strong they are (strength), especially in men.
