Capacity 02 · Recover From Stress
Signal · Blood Pressure

The pressure your system carries between beats.

Blood pressure is a recovery signal. Each beat is a pulse of force against the vessel wall; the question is whether your system returns to a calm baseline between them. Elevated average pressure is the body failing to unwind.


The ranges that matter

Four bands. One direction.

What matters most is the direction over time under the same conditions — is the number trending toward the Fit band, or drifting away from it? Your Radar scores every marker 0–100 on the same four-band continuum you see on your report: Fit (90+), Well (50–89), Short of well (26–49), Sick (25 and under). A score of 25 is the diagnosable line at any age. The values below are the age-40 reference — the bands shift with your age and sex, so use the calculator underneath for your own numbers.

Fit
MAP ≤ 85.4 mmHg
e.g. 118/72
Calm vascular baseline. Low chronic wall stress, and a system that returns to rest quickly.
Well
MAP 85.4 – 94.7
e.g. 125/78
Elevated but not diagnosable. Direction across many mornings matters far more than any single reading.
Short of well
MAP 94.7 – 96.7
e.g. 126/80
The Radar scores 25 at MAP 96.7. A systolic ≥ 130 or diastolic ≥ 85 also caps this marker at 55, whatever the MAP.
Sick
MAP ≥ 96.7
e.g. 134/88
Stage-2 hypertension caps the marker at 20 regardless of the average. Chronic elevation stiffens the whole arterial tree.

What it reveals

The wall remembers every beat.

Blood pressure is not one number. It is the pressure your vessels carry at peak output (systolic) and at rest between beats (diastolic). The gap between them — pulse pressure — and the average sustained load over months is what drives remodeling.

Each beat above baseline stiffens the arterial wall by a fraction. The wall adapts. The heart adapts. Over years, the whole system learns to live at a higher pressure — and the cost is paid upstream in brain, kidneys, eyes, and heart.

In coaching, we care less about a single high reading and more about the average across many mornings under the same conditions. The body is asking one question: can I return to baseline? Chronic elevation is the answer 'not quite.'

This sits in Recover From Stress because blood pressure is a window on sympathetic load, sleep, hydration, sodium/potassium balance, and vascular compliance. It is a recovery signal first, a risk marker second.

On the floor If morning pressure is creeping upward over weeks while training, sleep, and diet look similar — your system is not unwinding the way it used to. That is an early recovery failure, not just a cardiovascular number.
