What it is
Usual walking speed, in meters per second, over a short measured course. The paper is older adults. Training has been shown to change the walk. It has not been shown to change death.
How it is modeled (not scored)
Technical notes
The curve uses Studenski 2011 (9 cohorts, 34,485 community-dwelling adults 65+, mean gait 0.92 m/s): age-adj all-cause mortality HR 0.88 (0.87–0.90) per +0.1 m/s usual 4 m-equivalent pace; fully adj 0.90 (0.89–0.91). In that paper, 1.2 m/s “suggests exceptional life expectancy”; this calculator recentres HR=1.0 at 1.2 for a ~45 reference — ours, not their 0.92 mean. Veronese 2018 is the later measured-gait all-cause mortality meta (self-report excluded): community HR 1.12 per 0.1 m/s slower (inverse ≈ 0.89), still mean age 72, mixed clinical overall. Liu 2024’s 0.94 per 0.1 mixes self-reported walking pace. LIFE (Pahor 2014) cut mobility disability (HR 0.82) and did not decrease the death rate. No ~45 usual-4 m all-cause mortality meta-analysis is available.
How to improve it
- Walk regularly at a brisk, purposeful pace
- Add lower-body strength training (squats, step-ups)
- Work on balance and mobility to support a confident stride
