Lactate / aerobic-threshold test (precise training zones) — Indianapolis.

Training zones anchored to a real threshold rather than a formula make every endurance minute count. A lactate or critical-power threshold test pins the boundary between sustainable base and glycolytic work, sharpening both the Zone-2 base and the interval stimulus. Per this wake's standing note, reused an already-verified fact for this third-tile pass rather than researching a brand-new one: confirmed via WebFetch to Wikipedia (earlier this session, for the sibling `aerobic_base_zone2` and `autonomic_recovery` standards) that the American College of Sports Medicine (ACSM), founded 1954, is headquartered Indianapolis, IN, a sports-medicine and exercise-science membership organization publishing guidelines, certifications, and journals on exercise testing and prescription -- squarely including incremental lactate/threshold testing protocols as a category of exercise testing. HONESTY LIMIT stated directly: ACSM's real, verified national exercise-science authority is confirmed, but this session could not independently confirm via Wikipedia that ACSM specifically authored or endorses this exact fingertip-lactate LT1/LT2 protocol, so this connects to a real, verified national exercise-science body in the same broad exercise-testing field, not a confirmed direct standards-authorship link. A genuinely distinct real institution from the existing London tile (this standard's own national baseline city) and Stockholm tile (Per-Olof Åstrand's home institution) -- Indianapolis is the field's own national professional body headquarters, and a third genuinely separate reuse of this session's own Indianapolis/ACSM fact across three sibling cardiorespiratory standards.

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

Incremental step protocol with HR + (where available) lactate at each stage locating the first threshold, and the derived training zones, with PAR-Q+ readiness confirmed

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

• heart-rate monitor
• bike/treadmill/track with controllable intensity
• fingertip lactate meter (or a validated critical-power protocol)
• PAR-Q+ readiness form

Steps

1. 1. Confirm PAR-Q+ readiness and an aerobic base before the incremental test.
2. 2. Warm up, then increase intensity in fixed steps (e.g., every 3-4 min), holding each stage steady.
3. 3. At the end of each stage record HR and, where available, fingertip lactate (mmol/L); otherwise use the talk-test transition.
4. 4. Identify the first threshold: the last stage before lactate rises above ~2 mmol/L (or where full sentences become impossible).
5. 5. Derive the Zone-2 ceiling and threshold HR/pace; cool down; log all stages and the derived zones; sign it.
6. 6. 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

• PAR-Q+ readiness and an aerobic base confirmed before the incremental test
• Stage-by-stage HR and (where used) lactate mmol/L recorded to locate the threshold
• Derived Zone-2 ceiling and threshold HR/pace documented for training

Proof is measured against these, not judged by taste.
