start of 1:1-Block public summary

Brief Summary in Lay Language

The risk to injury his knee during lateral movements is higher than during other tasks. Female athletes have a higher knee injury risk than their male conterparts (2- to 8-fold) during such movements, i.e. sidesteps or cutting maneuvers.
One of the reason for this higher injury risk could be a different control of the upper body. It is assumed that the pelvis and trunk segment play a role in the coupling between the lower limb and the upper body. This coupling could be worse in female than male athletes.
Improving the coupling between the upper and lower body by means of a Core Stability Program could improve the control of the trunk and reduce the knee injury risk during lateral movements.
The aim of the study is to investigate in female athletes practicing team sports the effect of a Core Stability training on the biomechanics of lateral movements.

Brief Summary in Scientific Language

The risk to injury his knee during lateral movements is higher for female athletes than their male conterparts. During cutting maneuvers, the combination of knee valgus and rotation moments leads to high knee joint loads stressing the anterior cruciate ligament.
One of the reason for this higher injury risk could be a different neuromechanical control of the upper body. It has been shown that high lateral trunk flexion and external rotation increased the knee joint loading. Several studies suggest a core stability training to improve the neuromechanical coupling between the upper and lower body.
The aim of the study is to investigate in female athletes the effect of a Core Stability training on the control of the trunk and the loading of the knee joint during lateral movements. It has been hypothezised that trunk rotation and lateral flexion could be reduced and therefore that knee valgus moment would be lower after such a training.

Interventions/Observational Groups

  •   Arm 1: Training group A, healthy female participants practicing team sports. Measurements based on stereophotogrammetry. The Core Stability training will last 5 weeks, 3 x a week during 60 minutes.

  •   Arm 2: Training group B (control group), healthy female participants practicing team sports. Measurements are based on stereophotogrammetry. The perturbation training is based on lateral reactive jumps performed over a motor-driven plate that could move inducing perturbations upon landing. The training will last 5 weeks, 3 x a week during 30 minutes.

Primary Outcome

Changes in the control of the trunk and knee joint after a training based on core stability will be compared to the results obtained after a perturbation training based on lateral reactive jumps.
Kinematical data of the trunk (flexion, rotation, laetral flexion of the trunk with respect to the pelvis segment) will provide information about the control of the trunk. Knee joint moment values will give some insight in the control of the knee joint.
Measurements will take place before the 5 weeks training (baseline) and after this training (post measurement).
