Flight-to-Contact Ratio: Diagnosing Whether a Jump Problem Is Slow Contact or Low Flight
RSI dropped, but why? Split flight time from ground contact time to tell slow contact from low flight before you pick a fix.
Optimal Drop Jump Box Height: Find Your h-opt in 5 Tests
RSI drops once you pass your true peak height. Test 5 box heights 10 cm apart, plot the curve, and pinpoint your h-opt with this step-by-step protocol.
How to Perform Drop Jump RSI Test: Finding Optimal Height
Using the same drop height for every athlete skews RSI. This protocol covers box height selection, cues, and benchmarks for each athlete's optimal drop.
How to Test Reactive Strength Index Protocol
The RSI drop jump protocol in five steps: contact-time cutoffs, the calculation formula, and sport benchmarks so you know if your number is actually good.
How to Accurately Measure RSI with Drop Jumps
The wrong drop height skews your RSI numbers before the test starts. This guide covers optimal box heights, flight-time calculation, and norms by sport.
Drop Jump vs Depth Jump: Key Differences, When to Use Each, and How to Program Both
Coaches often use drop jump and depth jump interchangeably, but the technique and RSI targets differ. Here is when to program each, plus benchmarks.
Power Testing Protocols: A Coach's Complete Guide
CMJ, drop jump, isometric mid-thigh pull, or velocity-based test, which protocol fits your setup? Step-by-step standards for building one battery.
Reactive Strength Index (RSI): What It Is & How to Improve It
A low RSI score means slow ground contact is costing you power — how to calculate RSI, normative values by sport, and proven ways to raise it.
Reactive Strength Index (RSI): Complete Training Guide
There is no single good RSI score; the benchmark shifts by position. Covers measurement, position norms, ground-contact protocols, and progress tracking.
Drop Jump Exercise: Technique, Benefits & RSI Testing
Most drop jump errors trace back to ground contact time, not landing depth. Technique cues, common mistakes, and how to use drop jumps for RSI testing.
