How to Test 30-Second Anaerobic Power with a Jump-Based Protocol
No Wingate bike? This jump-based 30-second test gives coaches the same fatigue index and power-drop data, plus IMU-based interpretation norms.
How to Test Explosive Strength with IMU: 5 Validated Protocols
Explosive strength testing doesn't need a lab. Five 800Hz IMU protocols measure CMJ flight time, squat jump RFD, slam power, and barbell acceleration.
How to Test Takeoff Velocity in Vertical Jump: The 800Hz IMU Protocol That Beats Jump Height
Jump height is just an outcome; takeoff velocity is the real number. Here is the 5-step IMU protocol, normal ranges, and how to read your result.
How to Track a Pitcher’s Throwing Velocity with IMU: An 800Hz Sensor Standard Beyond the Radar Gun
Radar guns clock the pitch, not the arm behind it. An 800Hz IMU tracks 5 metrics like MER velocity, where injury risk climbs past 8,500 deg/s.
Why Snatch Form Matters More Than Weight: An IMU Perspective
Loading the bar before your technique is solid? IMU bar-path data shows why snatch form costs more power than adding kilos, plus an 8-week fix.
Force Deck vs IMU: Jump Measurement Accuracy, Metric Agreement, and Field Reality
A lab-grade force plate and an 800Hz IMU can still disagree on jump height. See the ICC, Bland-Altman limits, and which tool is accurate enough.
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.
Deadlift Velocity Zones Explained: A Science-Based Framework Using 800Hz IMU Data
Deadlift minimum velocity threshold is not squat's. See all five zones from 0.15 to 0.75 m/s, measured with an 800Hz IMU, and how to program each one.
How to Test Broad Jump Distance: An 800Hz IMU Protocol for Horizontal Power
See where your broad jump ranks against 7 populations from HS to NFL Combine, plus takeoff velocity, angle data, and 7 scoring errors to avoid.
Rotational Power Test Protocol: IMU-Based Standard Measurement Guide
Standard protocol to measure rotational power with 0.95 ICC reliability for baseball, golf, MMA athletes. 800Hz IMU analyzes asymmetry and output.
How to Measure Bat and Golf Club Rotational Velocity
Peak angular velocity separates elite swings from average ones. Mount an IMU on a bat or golf club, learn which metrics matter, and compare norms by level.
IMU Sensor Validity for Barbell Velocity Measurement: Systematic Review
A 23-study review found IMU sensors match lab-grade linear transducers within 0.01-0.04 m/s. Where that accuracy holds, and where it breaks down.
