Sled Push Load-Velocity Testing: A Field Protocol That Beats Guessing
Stop loading sleds by feel. Run this 5-load field test, calculate F0 and v0 from push velocity, and find each athlete's real power-peak load.
Rising Velocity Mid-Block: Real Gain or Artifact?
Velocity climbing at the same load mid-block? A checklist for telling real strength adaptation apart from technique cleanup and plain measurement noise.
When VBT Velocity Jumps After Caffeine: Reading It Right
A caffeine-driven bar speed jump isn't a strength gain. How to separate stimulant-driven VBT velocity spikes from a real 1RM improvement, with numbers.
Why a Two-Load LV Profile Gives You the Wrong 1RM
A two-load velocity profile can be off by 10-20% on your 1RM when the loads sit too close together or bunch at one end. Here's why - and the fix.
How Grinding Reps Corrupt Your Load-Velocity Curve and Skew 1RM Estimates
A single sub-maximal-intent rep can shift a load-velocity regression by 4-7% 1RM. Here's how to spot grinding reps and screen them out of your profile.
When to Recalibrate Velocity Zones Across a Mesocycle: Signals and Retest Rules
Your velocity zones were accurate in week 1 — are they still accurate in week 6? The strength-change signals and retest rules that tell you when to recalibrate.
How to Build a Velocity Zone Cheat Sheet for Every Lift
Stop guessing your training zones from memory. Collect load-velocity data, derive four personal bands, set velocity-loss caps, update every 4-8 weeks.
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.
Sex Differences in the Load-Velocity Profile: Evidence Review for VBT Practice
Do velocity zones and 1RM thresholds differ by sex? A 130-athlete study found the group curve holds, but individual variation tells the real story.
Load-Velocity Profiling for 1RM Prediction: Accuracy Review
Can load-velocity profiling replace a maximal 1RM test? This review breaks down error rates by method and which protocols hold up in practice.
Why Barbell Velocity Is the Most Accurate Predictor of 1RM: A Research-Based Analysis
RPE and rep-max formulas guess at your 1RM; barbell velocity measures it. 800Hz data shows why velocity beats both for predicting a true one-rep max.
How to Calculate Velocity-Based 1RM: Estimate Max Without Maxing Out
Submaximal velocity data predicts today's 1RM without a single max-out attempt. This guide covers the math, per-exercise thresholds, and accuracy limits.
