Have a click on this link - it is Ryan's landing technique!
What do you think?
Notice the slight collapse of the knee's when he goes to jump. This can lead to knee pain and worse still risk of ACL injuries.
On Ryan's landing, his knee's are strong - they do not collapse inwards and he bends his knee's on impact to absorb shock. This reduces his risk of knee injuries when landing, compared to if his knees fell in.
It is super important to train this technique as a part of your preparations and normal training. This reduces the risk of severe knee injuries! The preventative programs for AFL, Soccer, basketball and netball ALL look at landing mechanics and exercises to improve this. Unfortunately, there is always going to be a risk of injury, but if you could do something to reduce that risk - why wouldn't you?
