Measuring Power Without a Lab
The Measurement Problem
Power = Force × Velocity.
In a lab, power can be measured using:
- Force plates
- Linear encoders
- Velocity tracking systems
Most climbers do not have access to this.
So the question becomes:
What can we measure realistically?
What Power Means in Climbing
Climbing power is expressed as:
- Fast recruitment
- Explosive pulling
- Quick contact stabilization
- Dynamic force application
It is visible in:
- Deadpoints
- Dynos
- Fast lock-offs
- Contact strength moments
We must measure output indirectly.
Method 1: Standardized Board Benchmarks
The most practical proxy:
Fixed-angle board problem with:
- Defined hold set
- Defined movement
- Consistent conditions
Track:
- First-attempt success
- Total attempts required
- Movement quality
If strength is constant and power improves:
- Contact feels faster
- Fewer attempts are needed
- Movement becomes sharper
Board benchmarks are imperfect —
but repeatable.
Method 2: Contact Strength Proxy
Contact strength can be assessed via:
- Single-move dynamic latch
- Controlled jump-to-hold test
- Fixed campus touch test (low volume)
Measure:
- Success rate
- Stability after contact
- Number of stable repetitions
This does not quantify velocity directly,
but it captures applied force timing.
Method 3: Attempt Quality Tracking
Power deteriorates quickly under fatigue.
Track during session:
- Number of high-quality explosive attempts
- Time until noticeable velocity drop
- Consistency of movement sharpness
If explosive quality degrades after few attempts,
neural fatigue may be high.
This becomes a session-level power metric.
Method 4: Comparative Density
In fixed-intensity power problems:
Measure:
- Number of successful explosive problems in a set time
- Total quality attempts before velocity declines
Density under controlled rest gives indirect insight into power endurance.
But remember:
Power endurance is not pure power.
Keep them separate.
What Not to Use
Do not rely on:
- Pump sensation
- Session exhaustion
- Random gym dynos
- Flashing new commercial routes
These are noisy and style-dependent.
Power measurement requires repeatability.
Testing Frequency
Power fluctuates strongly with:
- Neural readiness
- Fatigue
- Sleep
- Psychological arousal
Testing too frequently creates confusion.
Use:
- 4–6 week comparison windows
- Same board
- Same angle
- Similar skin condition
Trends matter.
Single sessions do not.
The Interpretation Layer
If max hang improves but board benchmark does not:
Integration may be limiting.
If board benchmark improves but max hang does not:
Applied coordination may have improved.
Separate capacity from expression.
The Core Principle
Without a lab, power cannot be measured directly.
But it can be approximated through:
- Controlled board benchmarks
- Contact strength tests
- Repeatable explosive tasks
The key is consistency.
Measure what is repeatable,
interpret over time,
and avoid chasing single-session spikes.
