Expert information after PRE cuts |
Verbal instructions provided before each POST cut |
External knee abduction moment |
“An external knee abduction moment is a rotational force around your knee joint that can cause your knee to move inward, increasing the risk of knee injuries. By reducing the force, illustrated by the length of the arrow here, or bringing it closer to the knee joint, we aim to decrease the knee abduction moment shown in this graph. Targeted instructions will be provided to help you achieve this reduction.” |

Foot strike angle |
“The foot strike angle indicates how your foot lands when you cut. Landing flatfooted or with the heel first, corresponding to low or negative values in the graph, is associated with elevated knee abduction moments. To avoid this, try to land softly and with your forefoot first, corresponding to high values in the graph.” |
“Land softly and on your forefoot first.” |
Knee valgus angle |
“The knee valgus angle indicates the alignment of your knee between your foot and hip when you land. If your knee moves inward, corresponding to negative values in the graph, it can contribute to elevated knee abduction moments. To avoid this, press your foot and knee out to maintain proper alignment, corresponding to values close to zero in the graph.” |
“Avoid your knee falling inward by pressing your foot and knee out.” |
Vertical impact velocity |
“The vertical impact velocity indicates how fast your body moves downward and results from the height of your jump before the cut. High vertical impact velocities, corresponding to high values in the graph, are associated with elevated knee abduction moments. To make your cut more efficient, try jumping less high before the cut, corresponding to low values in the graph.” |
“Make your cut more efficient by jumping less high before the cut.” |
