start of 1:1-Block public summary

Brief Summary in Lay Language

The knee injury risk is higher when performing lateral movements as typically encountered during soccer or handball games. Females are at a 2- 8- fold higher risk to sustain an knee injury than males. One of the reason for that higher risk is the difference in knee joint biomechanics. However, the way the trunk is controlled seems also to play a important role.
It has been reported in few studies higher trunk lateral flexion and rotation for females than males.
Moreover, perturbations during the landing phase of lateral movement require a higher neuromuscular control of the the whole body and especially of the trunk. Such a training design would therefore stimulate the control of the knee joint and the trunk and possibly reduces the injury risk.
The aim of the study is to investigate the influence of such a perturbation training on the control of the knee and trunk and if the coupling between these two segments could be improved

Brief Summary in Scientific Language

The knee injury risk is higher when performing lateral movements as typically encountered during soccer or handball games. Females are at a 2- 8- fold higher risk to sustain an knee injury than males. The neuromechanical coupling between the trunk and knee joint plays a important role, especially be females who demonstrate higher knee valgus position and higher trunk abduction.
Moreover, perturbations during the landing phase of lateral movement require a higher neuromuscular control of the the whole body and especially of the trunk. Such a training design would therefore stimulate the control of the knee joint and the trunk and possibly reduces the injury risk.
The aim of the study is to investigate the influence of such a perturbation training on the control of the knee and trunk and if the coupling between these two segments could be improved
The improvement of the control of the trunk and knee joint after a training based on perturbation during lateral reactive jumps will be compared to the results obtained after a classical plyometric training. 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 as well as electromyography data will give some insight in the control of the knee joint.

Interventions/Observational Groups

  •   Arm 1: Training group A, healthy athletes practicing team sports will ball would be tested using stereophotogrammetry and electromyography methods. The perturbation training consists in performing lateral reactive jumps while landing will be perturbed and would take place 3x a week for 30min during 5 weeks.
  •   Arm 2: Training group B, healthy athletes practicing team sports will ball would be tested using stereophotogrammetry and electromyography methods. The plyometric training (control group) would take place 3x a week for 30min during 5 weeks.

Primary Outcome

The improvement of the control of the trunk and knee joint after a training based on perturbation during lateral reactive jumps will be compared to the results obtained after a classical plyometric training. 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 as well as electromyography data will give some insight in the control of the knee joint.
The dependant variables will be measured first before the start of the training and then after 5 weeks.
