Why a Wrist-Worn Sensor Under-Reads Vertical Jump Height
A wrist-mounted jump sensor tracks your arm swing, not your center of mass, and that mismatch quietly shaves centimeters off every jump. Here is the fix.
How Arm Swing Inflates Your Jump Test Height (And How to Fix It)
Loose arm-swing rules can shift CMJ and squat jump height by several centimeters between sessions. Fix hand position so numbers reflect leg power, not arms.
Single-Leg CMJ Asymmetry Testing: Protocol, Norms & Rehabilitation Use
Use the single-leg countermovement jump to detect limb asymmetries, track ACL return-to-sport progress, and guide VBT programming decisions.
How to Test the Jump Fatigue Index: Measure Neural Recovery Every Day
Quantify neural fatigue with five consecutive countermovement jumps. Step-by-step Jump Fatigue Index protocol, interpretation, and 800Hz IMU integration.
How to Test Eccentric Utilization Ratio: CMJ vs SJ Comparison
EUR reveals if a strength deficit is stretch-shortening or force-related. Calculate it from CMJ and squat jump heights, then match training to the profile.
How to Track Neuromuscular Fatigue with Daily CMJ
A daily CMJ protocol for catching neuromuscular fatigue early: threshold values, warm-up standardization, and a readiness score to act on before training.
CMJ Monitoring for Athlete Readiness: Research on Countermovement Jump as a Fatigue and...
A lower jump isn't always fatigue, but research points to thresholds that matter. Here's how CMJ flags overreaching and guides same-day training calls.
Countermovement Jump (CMJ): Technique, Measurement & Norms
The countermovement jump (CMJ) test — proper technique, measurement methods, normative data, and how to improve your CMJ score.
