Muscle Oxygen (NIRS) Motion Artifact Troubleshooting: Telling Sensor Slip From Real Desaturation
A SmO2 spike mid-interval isn't always desaturation. It can be sensor slip, thick adipose tissue, or strap pressure. Here's how to tell them apart.
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.
AI in Sports Analytics: Performance Monitoring Research
Which AI injury-prediction and load-management models hold up under real training data, plus how IMU sensors feed the readiness scores coaches rely on.
