Longevity diagnostics: three days, seven markers, a plan
The entry point to a spa stay: three days, seven biomarkers from Garmin devices, an extended blood panel and spectral HRV analysis — and a written stay plan at the end.
What it is. Programme 01 of the resort's ten Longevity programmes and the only one that treats nothing: it measures. The base stay is 3 days, which is also the minimum.
Why. So that the next programme is chosen from numbers rather than from a complaint at the desk: after the diagnostics the guest has body composition, a lipid profile, HbA1c, an HRV spectrum and seven markers from the watch.
How it is measured. By seven markers: VO₂max, Fitness Age, HRV, Resting HR and Sleep Score are computed by the portal from the hotel watch data (the fleet is Garmin Forerunner 165 / 165 Music), while BMI and Muscle Mass come from the Garmin Index S2 scale in the room.
The medical frame. Five items on the first morning, two on the second day, a specialist consultation on the last. In this programme the frame is the body of the course: the paid slots never pick its items up.
What it costs. The demo three-day plan comes to 15,150 CZK (≈ 606 EUR) in procedures; the room is counted separately, from 2,900 CZK a night.
Who decides. The algorithm drafts, the medical examination stands on the first morning, the doctor has the last word (how the algorithm works).
What the guest leaves with. A plan for the next programme, the specialist's conclusion and numbers they can come back to a year later: they stay in the guest's cabinet.

The seven markers the programme runs on
Every Longevity programme has its own set of markers. Diagnostics has seven, more than any other: it does not run a course, it describes the starting point — and it describes it from two sides, fitness and body composition.
Five numbers the portal computes from watch data, two arrive from the scale. The names are left in English: that is how they are labelled in Garmin Connect and on the watch itself, and how they stand on the programme tile in the portal and on the website shelf.
Marker
Where it comes from
What it means
Why it is in this programme
VO₂max (maximal oxygen uptake)
The Garmin watch; if the model does not report it, the portal estimates it from a walk
Millilitres of oxygen per kilogram per minute
The strongest single marker of endurance. The walk estimate uses the ACSM walking cost equation extrapolated on heart-rate reserve; the error of submaximal methods is about 5 ml/kg/min, so the portal shows the trend rather than a single figure
Fitness Age
Computed by the portal from VO₂max, sex and age
The age at which this VO₂max is the population median
Translates VO₂max into language a guest understands. Outside the normative table the portal does not show it at all: a 'fitness age of 85' from a noisy estimate frightens without telling anything true
HRV (heart rate variability)
The Garmin watch, overnight
The spread between heartbeats during sleep, ms
The state of autonomic regulation. Garmin's own verdict needs about three weeks of wear, so the portal compares the night with the guest's own average rather than with someone else's norm
Resting HR
The Garmin watch
Beats per minute at rest
A cheap and stable marker: a shift of a few beats shows up before the guest feels tired
Sleep Score
The Garmin watch, overnight
0–100 plus the structure of the night by stage
Sleep is the entrance to any programme: under a low score the doctor does not prescribe hard procedures
BMI (body mass index)
The Garmin Index S2 scale in the room
Mass divided by height squared, kg/m²
A rough frame. It is read together with muscle mass: for a trained guest BMI overstates the risk
Muscle Mass (skeletal muscle mass)
The Garmin Index S2 scale, bioimpedance
Muscle mass, kg
The main consumer of glucose at rest and the first thing lost with age. It decides which programme is offered next
The demo guest's 'My states' page: sleep 4:42 with a score of 53, variability 33 ms, Body Battery 73, resting pulse 61 bpm, 3,487 steps and blood oxygen 92 % — the single page the review starts from×
What the guest sees in the portal
The portal's front page is LONGEVITY: the rings of the day, 'Today's report' scored from 0 to 100 and the 'State by state' column, where every line explains what the number means today.
In the screenshot the demo guest's report is 48 out of 100 with the line 'Rest — the doctor decides': variability 33 ms, 19.9 % under their own average of 41.2 ms. On such a day the portal offers no hard procedures, and pulse ox acclimation of 88 % against a threshold of 90 % sends the guest to the doctor before any procedure.
The screenshots are in English on purpose: Garmin's product terms are not translated in any locale, while the portal itself speaks to the guest in their own language — the interface is translated into 36. The guest in the screenshots is fictional, this is the demo stand.

Three days: what stands in each
In diagnostics the medical frame does not top up the course, it is the course. The portal places it itself, by the length of the stay rather than by the budget: frame items never compete for paid slots.
The first morning is the examination, an ECG, INBODY, the drinking cure prescription and the blood draw. The second day is spectral HRV analysis and the life test. The last day is a specialist consultation — cardiology or gastroenterology, depending on what was found.
A stay longer than a week adds two more items: a doctor's consultation in the middle and a repeat INBODY the day before departure, so that the conclusion compares two measurements rather than one.

The results discussed and the next programme planned
The demo guest's three-day plan: day one is badged 'arrival & check-up' — five items, 3 × 150 ml of water and a 30-minute walk on route II; the blood draw is labelled as a day the reception confirms×
Four items whose day floats
The blood draw, spectral HRV analysis, the specialist consultation and the laboratory panel are marked in the plan: their day is a wish, not a booking.
The reason is domestic. The nurse works a short-week and long-week rota, and the appointment regularly slides to the next day. Promising a day nobody guarantees is the worst kind of precision, so the portal puts a sensible day and says plainly that the reception assigns the exact one.
The algorithm does not place them. In the procedure catalogue they are marked unplannable: ordinary programme slots never take them, only the diagnostic frame does.
They do not appear without a doctor. All four need a prescription, and the guest cannot add them from the shelf.
The blood panel price is an estimate. The extended panel is not in the printed 2026 procedure price list, the portal says so out loud, and the hotel corrects the number in the admin panel without a deploy.
A specialist consultation costs 2,000 to 5,000 CZK: it depends on who looks and how long the discussion takes.
Functional tests: three measurements without instruments
Besides the instruments, diagnostics carries a battery of three tests. They need no equipment: a stopwatch, a chair and a measured corridor. The thresholds are taken from published clinical work, not invented for the portal.
The six-minute test the watch records by itself — six minutes of walking is a distance, and distance is what the watch is for. In the other two the watch holds the stopwatch and files the result, but a human performs the test: the seconds are counted, the quality is not.
There is no dynamometer in the house. Grip strength was the fourth test and was dropped on 06.08.2026: the instrument does not exist here, and a 'not measured' line every morning teaches the eye to skip the three lines under it.
There are only three bands — low, ok, good. Five bands would promise a precision these tests do not have.
The six-minute test yields a second VO₂peak estimate from the Ross 2010 equation — a check on the same figure independent of the walk.

The frame: the walk, the pool and the drinking cure
Between the measurements the days are held by the frame rather than by procedures: the core of diagnostics is almost empty on purpose. Nordic walking three times a week, the pool four; on top of that oxygen therapy twice and one classic massage a week.
The walk and the drinking cure do not compete for slots: they are the spine of every programme at the resort and stand in every day. For the demo guest day one is 30 minutes on route II and three servings of 150 ml.
Guided Nordic walking — 60 minutes, 350 CZK; it also gives the portal the material for the VO₂max estimate.
The pool is included in the stay and carries no price in the estimate.
Oxygen therapy — 50 minutes, 550 CZK.
The drinking cure is prescribed on day one and then runs from its card: the spring, the volume, the temperature (the drinking cure).
What the stay costs
The estimate is built from the same plan: included items carry no price, paid ones carry a price-list line. For the demo guest on three-day diagnostics the procedures come to 15,150 CZK — about 606 EUR at the rate of 25 CZK to the euro the portal uses for reference.
The room is counted separately and per night: Standard — 2,900 CZK (≈ 116 EUR), Design — 3,400, Lux — 4,200, Junior Suite — 5,200 CZK. The city tax of 50 CZK per guest over 18 per night is paid at the reception and is not part of the estimate.
The most expensive item of the course is the extended blood panel (4,500 CZK); the cheapest paid ones are the ECG and the guided walk, 350 CZK each.

Diagnostics is an entry point, and the portal is built so that guests leave it for a treatment programme rather than for nothing.
The specialist's conclusion on the last day carries not only the result but the recommended programme: Metabolic Reset for high HbA1c with low muscle mass, Heart & Endurance for low VO₂max, Deep Recovery for an unbalanced variability spectrum.
The numbers stay in the cabinet. The guest sees them on their phone a year later, when they come back: the comparison with the previous stay builds itself.
The questionnaire is already filled in. The profile from the diagnostics is carried into the next programme's questionnaire — the same questions are not asked twice.
Diagnostics cannot be picked as a second goal. It is absent from the 'anything else worth improving' question: its core is nearly empty, and as an add-on to another programme it adds nothing.
The night loop and contraindications
Three days is a short stay, but the night loop works on it too. Not before 06:00 the night just past is compared with the guest's own average, and flags reach the doctor's morning sheet: resting pulse above the usual, variability below it, a Body Battery that did not charge, a short night.
What is free and ours the portal changes itself, what is paid it offers to the doctor. The owner of the platform drew that line.
On a flagged day the walk is 30 % shorter, but never under 20 minutes and never twice in one morning.
Contraindications remove items before the plan exists. The questionnaire collects them first, and a procedure in conflict never reaches the plan (the morning sheet thresholds).
An acute condition stops everything. The portal raises a 'see the doctor first' warning and issues no course until the doctor has seen the guest.
Who does what
The guest. Wears the watch, steps on the scale in the morning, comes to the measurements and marks the water they drink. They install no apps and open no accounts in anyone else's service.
The front desk. Hands out the kit, has the personal QR code scanned, confirms the day of the blood draw and returns the watch to the fleet at check-out (working with the apps).
The doctor. Sees the guest on the first morning, signs the plan, reads the blood panel and the variability spectrum, prescribes the next programme.
The spa coordinator. Books by the plan and moves bookings when a room is busy: the plan is a wish with opening hours, not a cabinet timetable.
The portal. Drafts the course, computes VO₂max and fitness age, checks the night and prints the doctor's morning sheet (the morning round).
Questions and answers
Why only three days? Diagnostics measures the starting point rather than changing it: the blood panel, body composition and the variability spectrum are taken over two mornings, and the third day is for the discussion. Treatment is the next programme, and that one is longer.
What of this cannot be done at home? Spectral variability analysis, INBODY by segment and having every number read by one doctor within one stay. The watch and the scale are handed out on site, and a guest's own device can be connected too (your own device).
Is wearing the watch compulsory? The instrument measurements and the conclusion happen either way, but five of the seven markers will not be collected without the nights: the portal computes them from watch data. In that case it says plainly that the data is missing instead of inventing numbers.
Can a guest take the diagnostics and leave? Yes. The plan for the next programme stays in the cabinet and can be picked up on the next stay.
Who sees the results? The guest and the resort doctor. Export and deletion live in the guest's cabinet (personal data).
