When Your Tennis Serve Speed Gun and IMU Disagree: Ball Speed vs. Racket Speed Explained
A racket IMU reading half your radar number isn't broken - it's measuring a different object. See the physics, two real studies, and how to read both.
How to Improve Hip and Glute Power: An 800Hz IMU-Verified Training Guide
Weak hip extension shows up as flat jumps and slow sprints. This 12-week protocol uses 800Hz IMU velocity zones, RFD, and jump height to build power.
How to Test Power Output in the Bench Press: 800Hz IMU Sensor Protocol for Upper-Body Power
Test bench press power output with an 800Hz IMU sensor. Step-by-step protocol covering mean velocity, peak power, and optimal load identification.
How to Fix Shoulder Impingement in Overhead Athletes: 800Hz IMU-Based 4-Stage Rehab Protocol
Nearly 6 in 10 impingement cases return when only pain is treated. This 4-stage, IMU-tracked protocol targets the scapular deficit behind the recurrence.
How to Improve Hex Bar Deadlift Power: A Step-by-Step 800Hz IMU Guide
An 800Hz IMU sensor shows exactly where the bar slows down. See the velocity-based training approach and 12-week periodized protocol behind it.
How to Improve Handball Throwing Power: 800Hz IMU Rotational Kinematics 12-Week Protocol
Elite handball throwers hit 130 km/h+ off a coordinated kinetic chain, not raw shoulder strength. This 12-week IMU protocol targets a proven +6 km/h gain.
How to Program Volleyball Jump Training: 800Hz IMU 12-Week Periodization Guide
The spike jump doesn't train like a generic vertical. Follow the 4-stage, 12-week progression with RSI and landing-load checkpoints from 800Hz IMU data.
How to Test Single-Leg Asymmetry: A Complete 800Hz IMU Protocol
A 10% gap between legs raises injury risk. This 5-step 800Hz IMU protocol finds single-leg asymmetry and shows how LSI data should change your programming.
How to Track Recovery with CMJ: Complete Guide to Daily Neuromuscular Monitoring
Daily CMJ testing flags overtraining before it costs you a session. See the 5 jump metrics an 800Hz IMU tracks and the fatigue threshold worth watching.
How to Train Triple Extension with an 800Hz IMU Sensor: The Complete Guide
Triple extension makes or breaks an Olympic lift, yet few lifters see their own sequencing. An 800Hz IMU tracks hip-knee-ankle timing and peak velocity.
Why Isokinetic Machines Are Overrated: The 800Hz IMU Paradigm Shift in Strength Assessment
Isokinetic machine limitations show up fast under real sport loads—Cybex and Biodex miss what 800Hz IMU sensors capture in the field. Here's the evidence.
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.
