Unfortunately, this study concluded that a DCS programme did not have any significant effect on trunk kinematics. It did, however, demonstrate significant improvement in LE kinematics in anticipated cutting tasks, which can reduce the risk of ACL injury in more predictable situations on the field.
Previous research performed on trunk mechanics during cutting and its correlation with ACL injury risk demonstrates that trunk side bend and rotation in the direction towards which the athlete plans to cut is associated with increased knee valgus and increased risk of ACL injury. Therefore, it may be more beneficial to investigate the utility of a programme that directly targets trunk mechanics vs. just dynamic core control exercises.
It must also be remembered that the cohort studied here was both small and relatively homogenous, in that it was all young, male, elite football players. This group of athletes may very well have had sufficient dynamic core control prior to the study.
These results do not mean that coaches and clinicians should not include dynamic core stability exercises in their training. In fact, the findings of decreased posterior GRFs, increased internal hip extensor moments, decreased internal knee valgus, and external rotator moments all serve to reduce stress on the ACL. Though these were found in anticipated cutting only, there are still a good amount of predicted cutting movements that occur during sport along with the unanticipated movements. Therefore, this training is not futile.
