Brief summary

In this case-control study, two- and three-dimensional landing biomechanics, by means of lower limb joint angles and moments (opto-electronic system with synchronised force plate), will be compared between 30 male volleyball/basketball players with a history of patellar tendinopathy and 30 healthy controls.

Interventions

DIAGNOSTIC_TESTBiomechanical analysis

3D analysis of landing manoeuvres.

OTHERFatigue protocol

A circuit of different tasks (e.g. jumping, sprinting forward and backward, side-stepping exercise) was performed to induce fatigue.
