Vitality Age Calculator

Formula Used:


VitalityAge = chronological age
              - (VO₂max - 35) * 0.5
              + (resting heart rate - 60) * 0.2
              - (HRV - 50) * 0.1
              + (fat percentage - 20) * 0.3
              - (muscle mass / lean body mass) * 5
              - (strength level - 5) * 1.5

Chronological Age: Your actual age in years.

Resting Heart Rate (bpm): Lower values suggest better cardiovascular fitness.

VO₂max (ml/kg/min): Maximal oxygen uptake—higher values suggest a younger biological age.

HRV (ms): Higher variability indicates better autonomic nervous system balance and recovery.

Fat Percentage (%): High fat levels are associated with metabolic stress and aging.

Muscle Mass (kg): More muscle supports vitality and resistance to aging.

Lean Body Mass (kg): Used to calculate muscle ratio (muscle/LBM).

Strength (1–10): Subjective estimate of total body strength.
