How do we know we are improving?
We have a variety of tests to gauge individual progress. It's significant because as fitness improves, margins get smaller.
Physiological assessment is how your body responds and adapts to training.
It's hard data that doesn't lie.
Examples:
🧡 Heart rate testing during easy, threshold, or interval running
🧡 VO2 max pace/lab testing
🏋️♂️ 1/5/10 rep max testing on a strength exercise
🏃 3D Gait analysis testing
Reliable, repeatable, easy tests that measure training
Why test runners?
• Identify strengths & limiters
• Validate if training is working
• Guide smarter program design
• Build motivation through progress
We can do this through lab & field testing
Key point:
🔥 Changes in trained runners are small. 🔥 Changes in novice runners are larger.
🔥 Testing must be repeatable & sensitive to matter.
This may be taking 5 seconds off a 1600-meter time, a significant difference for some.
Variation is normal:
• Biological (sleep, stress, fueling)
• Technical (equipment, protocol)
Every individual is slightly different from 1 day to the next, as they are different athletes from 1 year to the next.
This is why consistent testing > one-off tests.
Fitness is fluid and ever-changing. Data should guide decisions.
