Evidence
- Prospective cohorts: 5 kg lower grip strength associated with 15–20% higher all-cause mortality independent of other risk factors.
- PURE study and others: grip strength outperformed systolic blood pressure as a cardiovascular mortality predictor in some analyses.
Reference ranges
- Male adults: 40–60 kg peak; women 25–40 kg peak.
- Age-declines steepen after 60; sex- and age-adjusted norms are widely published.
- Absolute cutoffs used for sarcopenia diagnosis: <27 kg (men), <16 kg (women) per EWGSOP2.
Device options
- Jamar dynamometer: the reference standard.
- Camry / commercial digital dynamometers: cheaper, adequate for tracking within-person changes.
Use in longevity practice
- Baseline measurement at age 40–50; annual repeat.
- Downward trends prompt resistance-training intervention.
- Cheap enough to buy for home use.
- Gait Speed — Biomarker.
- Frailty — Disease.
