Leg-power (stair-climb) assessment + power progression for older adults — Boston.

Boston, MA is home to the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University's Friedman School of Nutrition Science and Policy, confirmed via WebFetch to Wikipedia as the largest research institution in the world devoted to investigating the relationship between nutrition and aging -- the literal research center behind this standard's Reid & Fielding 2012 power-mortality citation. A distinct connection from this library's existing Philadelphia tile, which is built on that city's own rowhouse-stairs daily-life context rather than the underlying research's academic origin, and a distinct reason from this library's other Boston tiles (Czeisler's circadian research; I-Min Lee's step-count epidemiology) for a third genuinely different Boston-area research program.

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+ screen + measured staircase height + body mass + timed ascent + computed leg power (watts) vs age/sex reference, with a coached rate-of-force + tendon-loading progression

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

• a measured staircase (known step count + rise) with a handrail
• stopwatch/timer
• body-weight scale
• tape measure (step rise)
• PAR-Q+ or clinician clearance note
• heart-rate monitor (optional)

Steps

1. 1. Screen with PAR-Q+ FIRST: cardiovascular disease, uncontrolled BP, recent falls, severe balance/joint/tendon problems, or symptoms (chest pain, dizziness) -> route to a clinician or physical therapist for clearance before any power test or plyometric progression. Do not proceed if flagged.
2. 2. Measure the staircase: count steps and measure the rise per step to compute total vertical height; confirm a solid handrail and clear, dry footing.
3. 3. Record body mass; have the person ascend the flight as fast as they safely can, using the rail as needed, and time it. Two attempts with full rest between; keep the faster.
4. 4. Compute leg power = mass × 9.81 × total height ÷ time (watts); compare to an age/sex reference as a fall-risk/trend signal, not a diagnosis.
5. 5. Set a conservative coached progression: build rate-of-force intent (fast, controlled concentric) in safe patterns (sit-to-stand, step-ups) before any low-amplitude plyometrics, with heavy-slow resistance for tendon adaptation; progress volume before intensity.
6. 6. Record the height, mass, time, computed power, reference comparison, screen result, and the progression plan; sign. Route any red flag to a clinician / physical therapist.

What counts as done

• Completed PAR-Q+ screen (cleared, or routed to a clinician / physical therapist)
• Staircase vertical height (steps × rise) + body mass + timed ascent recorded
• Computed leg power (watts = mass × 9.81 × height ÷ time) compared to an age/sex reference as a fall-risk/trend signal, not a diagnosis
• Coached progression recorded (rate-of-force intent → heavy-slow tendon loading → cautious low-amplitude plyometrics)

Proof is measured against these, not judged by taste.
