What is the reactive agility deficit?

RAD = Reactive test time - Planned test time. A large RAD (>0.3s) suggests the athlete's limitation is decision-making and perceptual speed rather than physical change-of-direction mechanics.

How does reactive agility testing differ from traditional agility tests?

Traditional agility tests (T-test, 5-10-5) use predetermined paths. Reactive agility tests require the athlete to respond to a visual stimulus (light, arrow, opponent movement) to decide direction.
