Functional age is an indicator that compares the biological age of your body, how your organism actually feels, with your chronological age.

What Functional Age Means

Lower functional age = your body is in better condition than the average person of the same age and gender.
It handles stress, load, and recovery more effectively.

Higher functional age = may indicate fatigue, long-term stress, or an imbalance between load and recovery.

How Elonga Calculates Functional Age

Functional age in Elonga is designed to be:

• balanced,

• easy to understand for everyday users,

• motivating rather than discouraging.

The goal is to provide realistic, long-term motivating feedback that supports gradual improvement.

What Influences Functional Age

Functional age is determined by:

• the state of the autonomic nervous system (HRV),

• long-term trends in recovery and stress,

• lifestyle quality (sleep, movement, mental load, nutrition, etc.).

With regular morning measurements, consistent optimal physical activity
(ideally following the movement plan), and overall lifestyle improvements,
your functional age can gradually decrease, reflecting better fitness and resilience.
