Jump Test

Drop Jump

The test is applied to quantify jump performance related to an athlete's stretch-shortening cycle. In particular, it evaluates the quickness and reactivity in the transition from absorption to propulsion during landing and rebound. In addition, the text examines loading patterns during ground contact as a measure for musculoskeletal control in the knee and in the ankle joints.

Description

The Drop Jump test is a double-legged plyometric 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 remain on the hip throughout the entire movement. 3 repeats are performed, the jump with the highest ReGo Score is evaluated. The goal is to spend as little time as possible on the ground and to jump as high as possible.

Test Preparation
