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

In a rowhouse city where daily life already means stairs, older residents lose leg power silently until a stumble becomes a fracture. Measuring stair-climb power and coaching a safe rate-of-force progression converts the stairs they already climb into both a test and a training tool.

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.
