Jump Test

Drop Jump Test

The test is applied to quantify the quickness and reactivity of an athlete in the transition from absorption to propulsion during landing and rebound in a jump movement, as well as to examine loading patterns during ground contact as a measure for musculoskeletal control in the knee and ankle joints in particular.

Description

The Drop Jump test is a double-legged jump test and involves dropping from an elevated platform onto the ground with both feet, absorbing the drop and immediately propelling back up (rebound) into a maximal vertical jump and a final landing.

The test poses a fast stretch-shortening movement on the lower extremities as the eccentric landing phase is amplified by means of the dynamic drop component. Hands shall rest on the hip. 5 repeats are performed, the 3 best jumps are evaluated. The goal is to spend as little time as possible on the ground and to jump as high as possible.
