A study in the Journal of Athletic Training found that volitional abdominal contraction prior to a landing created a protective advantage to the ACL.
Core training that strengthens the core and hips allows for greater control of the pelvis during landings.
This pelvic control helps with knee stabilization, protecting against injuries.
A sore knee will prevent you from jumping high and training to jump higher.
To help protect your knees, train for core stability.
Anti-rotation, flexion and extension-based exercises should be used to optimize control of the hip and knee on landing.
