Clinical Trial Summary

There is a large number of young women who sustain serious knee injuries from playing soccer. Female athletes are at high risk of knee injuries from soccer than males. We will conduct a research project to assess the effect of a warm-up on changing some of the movement patterns thought to contribute to these serious knee injuries.

It is hypothesized that a core position and control movement strategy (Core-PAC) group reduce biomechanical risk factors at the knee compared to a control after the training program.

Description:

There is a large number of young women who sustain serious knee injuries from playing soccer. Female athletes are at high risk of knee injuries from soccer than males. We will conduct a research project to assess the effect of a warm-up on changing some of the movement patterns thought to contribute to these serious knee injuries.

A core position and control movement strategy (Core-PAC) may be one method of modifying high-risk movements such as side-cutting. The Core-PAC is a simple method of getting the centre of mass (COM) closer to the plant foot or base of support (BOS). Moving the COM closer to the BOS may bias joint loading to the sagittal rather than the frontal and transverse planes, which often occurs in female athletes and poses a risk for ACL injury.

In this study, we will conduct a randomized controlled trial to compare a Core-PAC trained group to a control group for peak flexion angles and peak abduction moments at the knee during a side-cut and an unanticipated side-cut prior to kicking a soccer ball and a side-hop task after a six-week training program.

It is hypothesized that a Core-PAC group would have greater peak flexion angles and lower peak abduction moments at the knee compared to a control after the training program.

Primary	Peak knee flexion angle and peak abduction moment	Intervention group will be instructed to move from the trunk first during a series of athletic tasks. The Control group will be instructed to move with their usual athletic movements during the same tasks.; After 6 weeks of this training, subjects will be asked to return to the GF Strong Rehabilitation Center for biomechanical testing.	6 weeks	No
