Vital Signs & Cardiac Calculators
Five free calculators for heart rate, walking speed, and running pace — the measurements that track cardiovascular fitness and long-term mobility at any age.
What this category covers
Resting heart rate and walking speed are the two most informative single measurements of cardiovascular fitness and long-term functional health. Both are responsive to training and are used as primary endpoints in clinical research:
- Resting heart rate — a low (within healthy range) RHR is one of the strongest markers of cardiovascular efficiency and longevity.
- Walking speed — usual-pace walking speed predicts 10-year survival in adults over 65 (Studenski 2011, JAMA).
- Gait speed norms — clinical reference values by age and sex, including fall-risk cutoffs for older adults.
- Running pace calculators — convert time, distance, and pace, and see 5K-to-marathon finish times.
For cardio performance tests like the beep test and shuttle run, see the Fitness Tests & Standards category.

How to measure at home
Resting heart rate: sit quietly for 5 minutes, place two fingers on your wrist (radial) or neck (carotid), count beats for 30 seconds, multiply by 2. Best measured first thing in the morning.
Walking speed: measure a known flat distance (10 m is standard), walk at your usual pace, divide distance by time. Our walking-speed calculator has a built-in timer mode.
