Countermovement Jump Protocol: A Practical Guide
A repeatable field setup for the jump test, with the choices that make a score worth keeping.

One Human Performance connects training, recovery and measurement for coaches, athletes and curious practitioners. Useful detail, clear limits, no miracle scores.
We read the study, name the protocol, and explain what changes when the test leaves the lab. Explore broad topics below, then go deeper into the method.
Broad doors for the field. Specific questions inside.

Strength, power and programming explained through the decisions that make a session useful.

Velocity feedback can sharpen load decisions, but the research does not support a universal replacement for percentage-based training.

A force-velocity profile is a model of a task, not a complete portrait of an athlete.
Wearables can make sleep visible, but a neat readiness number can hide uncertainty in the measurement.

A timing gate is only as useful as the start rule, distance, surface and repeatability around it.

Screens can organise a conversation about movement. They cannot predict an individual future from one score.

A deload is a change in training stress made for a reason, not a ritual week on a calendar.

Threshold is a useful training idea only when the intensity, duration and purpose are named.

The quality of a jump or landing session depends on more than a contact count.

A sensor can collect data without making the interpretation valid.

Observe the landing task in context before assigning a label to the athlete.

Readiness is a decision context made from repeated signals, not a coloured ring on a dashboard.

Procedure, equipment, population, reference context and limitations in one calm place. Start with the countermovement jump protocol, then compare the method with your own setting.
