RFD
Isometric Bench Press Test: Measuring Upper-Body Force and RFD
No bar path, no technique, just output: the isometric bench press test isolates pressing force and RFD the same way the IMTP does for the lower body.
Rate of Force Development Training Methods: Evidence Review
Ballistic, heavy, isometric, and plyometric training rank differently by RFD phase. See loads, frequency, and the 5-rep protocol behind each.
How to Train Explosive Knee Extension: An 800Hz IMU Guide to RFD, Jump Power, and Velocity
Explosive knee extension training raises jump height and sprint speed. An 800Hz IMU tracks knee RFD across a 12-week protocol built for up to 71% gains.
Why the Isometric Mid-Thigh Pull Matters: The Gold Standard for Maximum Strength Assessment
The isometric mid-thigh pull remains the gold standard for peak force and RFD testing. See how IMU sensors extend IMTP data into daily velocity tracking.
Why 30% Velocity Loss Is the Best VBT Cutoff: A Meta-Analysis of Pareja-Blanco and Beyond
Stop guessing when to end a set. Pareja-Blanco's data shows a 30% velocity loss cutoff balances hypertrophy and power better than VL10, VL20, or VL40.
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 Train Explosive Hip Extension: An 8-Week Protocol for Bigger Jumps and Faster Pulls
Untrained lifters average 1,800 N/s of hip RFD; elite jumpers exceed 4,500. This 8-week, IMU protocol targets the 20-30% gain behind explosive jumps.
How to Train Grip Strength Velocity with an 800Hz IMU Sensor
Peak grip strength means little if it arrives too slowly. An 800Hz IMU measures grip RFD and acceleration, exposing a gap most lifters never even test for.
Force-Time Curve Analysis: Performance Assessment Methods
Two athletes can jump the same height with very different force-time curves — and different injury risk. Here's how curve shape is measured in practice.
Rate of Force Development: Explosive Strength Factors
RFD separates athletes who look strong from those who are fast off the ground. This covers the neural and fiber-type factors, plus how tests measure it.
Force Plate Testing Guide: Key Metrics, Protocols, and Practical Alternatives
Not sure which force plate protocol fits your goal? Compare CMJ, drop jump, IMTP, and RFD tests against normative data tables coaches actually use.
How to Improve Rate of Force Development
RFD benchmarks span 800 N/s in untrained lifters to over 9,000 N/s in elite weightlifters. See where you rank, then close the gap with proven methods.
