Isometric Squat Test: Setup, Protocol, and How It Compares to IMTP
Get the knee angle wrong and the whole session is wasted data. Here is the isometric squat rig setup, trial protocol, and how it stacks up against the IMTP.
RSI-Modified Explained: The Countermovement Jump Reactive Metric
Your CMJ height looks fine, but something's off in the timing. RSImod explains why — the formula, protocol, real research findings, and common testing errors.
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 Set Up Force Plate Testing: Step-by-Step
A miscalibrated force plate ruins every test after it. Follow the setup, zeroing, athlete positioning, test selection, and interpretation steps in order.
How to Use Force Plates Effectively
Force plates measure more than jump height: jump analysis, asymmetry testing, and readiness monitoring, with step protocols and metric norms.
Force Plate Testing Without a Force Plate: Affordable Alternatives
Lab force plates run $8,000-30,000. IMU sensors, timing mats, and jump tests deliver comparable jump-height and RSI data for a fraction of that cost.
Jump Height Measurement Methods: Accuracy Comparison Study
Jump mats read 4.6cm higher than force plates on average. Compare force plate, IMU, video, and mat error rates to pick the right tool for your context.
Jump Height Measurement Methods: Flight Time vs Force Plate
The h = g x t^2/8 formula assumes equal takeoff and landing height. Hip pike and knee bend break that and skew results 1-3cm. IMU validation data inside.
Countermovement Jump Test: Complete Protocol & Norms
Complete CMJ test guide: standardized protocol, force-time curve interpretation, normative data by sport and sex, and how to use CMJ for fatigue.
Isometric Mid-Thigh Pull (IMTP): Testing Protocol, Norms & Applications
How to run the isometric mid-thigh pull correctly: bar height, ramp instructions, force-time variables to track, and normative data for comparison.
