IMU
Multi-Sensor Time-Sync Offset Is Corrupting Your Analysis: How to Find and Fix It
Force plate, IMU and video each start their own clock, and a 20ms gap between them can flip your phase timing and RSI. Here's how to catch and align it.
IMU Magnetometer Interference Indoors: Why Steel Gyms Cause Heading Drift
Steel racks and rebar bend the local magnetic field and corrupt IMU heading. Two lab studies quantify the drift and the floor-mapping fix that controls it.
IMU Gyroscope Saturation in Rotational Sports: Why the Data Flat-Lines and How to Fix It
A flat 2,000°/s ceiling on a pitcher's shoulder trace isn't a bug — it's gyroscope saturation. Here's how to spot clipped data and set the right range.
IMU Drift and Sensor Fusion: Why Your Data Wanders and How It's Fixed
A bar velocity reading that creeps upward for no reason isn't a broken app. It's uncorrected IMU drift, and a 90-second calibration habit controls it.
IMU Sensor Placement: Best Practices for Reliable Movement Data
Where you strap an IMU changes the number it reports. A field guide to lumbar, sternal, wrist, and shank mounts, with the errors that quietly wreck data.
Timing Gates vs IMU: Which Sprint Timer Is Worth It?
Timing gates and IMU sensors both promise accurate splits, but differ in setup time and cost. See which fits a 20-athlete squad versus a solo trainer.
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.
How to Improve Acceleration in Football: IMU-Driven 0-10m Sprint Power Protocol
This 12-week protocol uses IMU jump and barbell velocity data to find where power leaks and build 0-10m acceleration in football players.
How to Train Football Throwing Power: A 12-Week IMU and Medicine Ball Program
Long throw distance in football comes from rotational power, not arm strength. A 12-week IMU program added 14% to throw distance with medicine ball work.
Power-Time Curve of the Clean: An 800Hz IMU Analysis of First Pull, Transition, and Second Pull
The clean's power-time curve puts 60-70% of total power in the second pull. See how 800Hz IMU data from PoinT GO breaks down each phase of the lift.
Why Warmup Jumps Predict Performance: The Science of Neuromuscular Readiness
A flat warmup jump can be an early warning sign. RSI and jump-height shifts during warmup forecast same-day performance via 800Hz IMU tracking.
IMU Data Interpretation for Coaches: Turning 800Hz Jump and VBT Data into Decisions
RSI, jump height, and velocity numbers on a report — now what? A practical guide to reading 800Hz IMU data and turning it into load and selection calls.
