Submaximal VO2max estimate + percentile — New Orleans.

Low cardiorespiratory fitness is the single strongest modifiable predictor of all-cause mortality, yet most adults have never had VO2max measured. Without a number and percentile, there is no baseline to train against or trend to track. New Orleans rebuilt its safety net after Hurricane Katrina around community health centers rather than the old Charity Hospital model; CrescentCare, now one of the city's largest, became a federally qualified health center in 2013 on more than 40 years of prior community-health work and is a real route to PAR-Q+ clearance.

Pay

$200 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

PAR-Q+ resolved + protocol named + raw inputs (time, HR, mass, age) + estimated VO2max (ml/kg/min) + age/sex percentile + timestamped photo of course and HR readout

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• GPS phone or measured 1-mile flat course (or a 12-inch step + metronome)
• heart-rate monitor (chest strap preferred; wrist acceptable)
• stopwatch
• PAR-Q+ readiness form

Steps

1. 1. Complete the PAR-Q+ readiness screen; if any exertion flag is positive, STOP and route to clinician clearance before testing.
2. 2. Record age, sex, body mass (kg), and resting heart rate after 5 min seated.
3. 3. Warm up 5 min at an easy pace.
4. 4. Rockport: walk 1 mile as fast as sustainable on a flat course; record finish time (min:sec) and immediate post-walk HR. YMCA step: step up-down on a 12-inch box at 96 beats/min for 3 min, then sit and record the 1-minute recovery HR.
5. 5. Estimate VO2max (ml/kg/min) with the protocol's validated equation from mass, age, sex, time, and HR.
6. 6. Convert the estimate to an age/sex percentile against the FRIEND reference and record METs.
7. 7. Photograph the course/step and the HR/time readout; log VO2max, percentile, protocol, and conditions into the proof record and sign it.
8. 8. Record any beta-blocker or other rate-controlling medication; if present, do not apply age-predicted %-max-HR zones or standard heart-rate thresholds — anchor intensity with RPE and the talk test instead.

What counts as done

• Completed PAR-Q+ readiness screen (no unresolved exertion flags)
• Protocol named (Rockport 1-mile walk or YMCA step) with raw inputs
• Estimated VO2max in ml/kg/min with the age/sex percentile
• Timestamped photo of the measured course/step and the HR/time readout

Proof is measured against these, not judged by taste.
