Estimated 1RM Keeps Changing Daily: Is It Noise or Real Readiness Drift?
Your velocity 1RM swings 8kg between sessions with nothing changed. Separate measurement noise from real readiness drift and build a stable baseline.
When Tester Strength Biases Handheld Dynamometer Readings
Handheld dynamometer scores shift with who holds the sensor. See why make vs. break testing hides tester-strength bias, and the fixation fix that removes it.
Mean vs Peak Velocity in VBT: Which Metric Should You Use?
Mean velocity, mean propulsive velocity, or peak velocity — they do not track load the same way. This review shows which metric fits which exercise.
IMU Jump Height Accuracy vs Force Plate: Research Review
Can wearable IMU sensors replace a force plate for measuring jump height? This review breaks down validity and reliability data across lab and field.
VBT vs RPE: Which Is More Accurate? A Practical Field Guide
We tested velocity-based training against RPE on precision, reliability, and cost. See the load, tempo, and progression cues each method gets wrong.
