Sports science, distilled.
Summaries and analysis of key research papers in sports science, velocity-based training, and performance measurement.
Why Jump Asymmetry Is the Strongest Predictor of Injury Risk: The Science of Asymmetry via 800Hz IMU
Jump asymmetry outpredicts every other test for ACL and hamstring injury. Twelve studies and 800Hz IMU data show why balance testing alone falls short.
Why Jump Height Drops with Fatigue: The Neuromuscular Science
A 5-15% jump height decrease under fatigue isn't random. Neuromuscular fatigue, RFD loss, and SSC decline explain it, backed by 800Hz IMU tracking data.
Jump Mat vs IMU: A Scientific Comparison of Measurement Accuracy
Jump mat vs IMU accuracy compared against force plate validation data. See where each device gains or loses reliability before you pick your testing tool.
Why Jump Squats Trump Back Squats for Power Development: An 800Hz IMU Analysis
Jump squat power output beats back squats on velocity and RFD. 800Hz IMU sensor data breaks down the numbers so you know which lift builds explosiveness.
Why You Must Monitor Load-Velocity Every Session - The Science of Daily Variability and Autoregul...
Your 1RM can swing 18% day to day. Load-velocity monitoring every session catches that shift before autoregulation math goes wrong. Here's the proof.
Why Most Lifters Overestimate Their 1RM: The Science of Measurement Error
78% of lifters overestimate their 1RM, missing by 8.7% on average. IMU velocity data catches the error and fixes load prescription for good.
Why Recovery Velocity Tells Everything: 800Hz IMU Truth About Neuromuscular Fatigue
A 12-week, 28-athlete 800Hz IMU study shows recovery velocity reveals neuromuscular fatigue more accurately than 1RM testing ever could on its own.
Why Rest Time Affects Power Output: ATP-PCr Recovery, Neural Fatigue, and Sensor-Based Optimization
Cutting rest short kills power output. See what ATP-PCr resynthesis and neural fatigue data, measured via 800Hz IMU, say about the ideal window.
Why Sprinters Need VBT Tracking: Velocity Transfer From Weight Room to Track
Sprinters who track bar velocity in the weight room gain 11-17% more explosive power. Here is the 800Hz IMU evidence behind the velocity-to-track transfer.
Why Triphasic Training Works: Neuromuscular Mechanisms and Sensor Data
Most programs train max strength, speed-strength, and reactive strength separately. Triphasic training layers all three at once, backed by 800Hz IMU data.
Why Undulating Periodization Outperforms Linear Models: The Science of Neuromuscular Adaptation
Daily undulating periodization (DUP) keeps beating linear programs in head-to-head strength studies. Meta-analyses and 800Hz IMU data explain why it wins.
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.
