NCT04339569

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.

Outcome Measures

Primary Outcomes (1)

  • Change in landing biomechanics (kinematics and kinetics)

    Trunk and lower extremity joint angles and moments will be extracted with an opto-electronic system and synchronised force plate

    Immediately after fatiguing exercises

Study Arms (2)

History of patellar tendinopathy

Diagnostic Test: Biomechanical analysisOther: Fatigue protocol

Healthy controls

Diagnostic Test: Biomechanical analysisOther: Fatigue protocol

Interventions

Biomechanical analysisDIAGNOSTIC_TEST

3D analysis of landing manoeuvres.

Healthy controlsHistory of patellar tendinopathy
Fatigue protocolOTHER

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

Healthy controlsHistory of patellar tendinopathy
