Step-by-step, no fluff.
Practical guides for improving athletic performance and training smarter with measurable data.
Mountain Bike Repeated Climb Power Test: Scoring XCO Fatigue Resistance
One clean climb time won't predict lap five. A repeated-climb protocol that scores power maintenance across 5 reps, built for XCO race demands.
Neck Isometric Strength Dynamometer Protocol: 4-Direction Setup and Concussion-Risk Interpretation
Neck strength dynamometer testing done sloppily wastes a preseason baseline. A 4-direction setup, scoring math, and normative bands for contact-sport screening.
Monitoring Fatigue-Induced Landing and Jump Decrement in Netball
Track late-quarter landing collapse and jump height loss in netball to flag substitution windows before ACL-risk mechanics show up on court.
Padel Repeated-Sprint and Change-of-Direction Test: A Short-Court Protocol
Straight-line sprint tests miss what padel actually demands: 7m bursts, glass rebounds, a turn every few seconds. Here's a protocol built for that.
How to Measure Seated Throw Power for Para-Athletics
Throw distance can't tell you if extra range came from trunk or arm. Get the field protocol that isolates each, plus class norms and 2 cited studies.
Player Load Spikes as False Positives: How to Fix the Unit Shake Artifact
A loose harness can add 40+ AU to a session with zero real work behind it. Here's how to spot a Player Load false spike and stop it at the source.
Prone Hamstring Isometric Dynamometer Test: A Reproducible 15-Degree/90-Degree Knee-Angle Protocol
Handheld dynamometer hamstring numbers swing between testers because the device is hand-resisted. A strap-anchored 15-degree/90-degree protocol that holds up.
Repeated Jump Anaerobic Endurance Test: Protocol, Fatigue-Slope Scoring, and Norms
A single jump height tells you nothing about round 15. A 20-jump field protocol that fits a fatigue slope to the decline and scores real anaerobic endurance.
The 2k Erg Benchmark Test: A Drag Factor and Pacing Protocol for Comparable Scores
Same rower, three different 2k times, no fitness change. A protocol for locking drag factor and pacing so 2k erg scores actually compare across sessions.
The 30-Minute Rowing Critical Power Test: How to Measure CP and W' on the Erg
Most rowers guess threshold from a discounted 2k split. A 30-minute erg test pulls out real critical power and W' with the math, cutoffs, and zones.
Rowing Erg Drag Factor: Why It Silently Breaks Your Watt and 2K Comparisons
Locking the damper lever isn't locking resistance. Drag factor drift quietly wrecks watt and 2K comparisons across sessions, and here's the fix for it.
RSI Inflated by Short Contact Time: How to Find and Fix the Measurement Error
A drop jump reads RSI 3.1 with a 0.09s ground contact time that felt nothing like a stiff bounce. Here's why timing-gate error inflates RSI and how to retest.
