LOCKED KNEE OR NOT LOCKED KNEE? THAT IS THE QUESTION...

🔹I had a question from @b_qian6 last week regarding hyper extended knee and what my thoughts were. 🔸I’ve picked out 2 videos. Zelezny from the 1995 World Champs and Vetter from the 2017 edition, primarily because there is data to support. It’s important to stress at this point, these are the top two throwers of all time! 🔹Firstly both won gold so the discussion about a straight (er) front leg carries weight in this regard. You’ll see that at FFC Zelezny’s knee was 173 degrees (apologies for the poor quality table). Vetter on the other hand displayed a 190 degree knee angle, which is clearly a significant hyper extension and even more so when decelerating a significant frame travelling in excess of 7ms^-1. 🔸Both championships were won with 89m+ so the outcome was broadly the same, and reading down the results list you can see that in general a straighter front knee is beneficial (note Röhler at 192.4 degrees). As ever there are anomalies. 🔹My thoughts are as follows: ▶️ A braced (non collapsing) front leg which resists flexion is what I would consider desirable. ▶️ The ability to execute this will strongly relate to the processes which have preceded it. ▶️ A hyper extended knee is extreme and likely not a ‘trained’ quality but something that occurs because the individual strives to brace and thus block with solid mechanics but moreover can actively ‘hyper-extend’ due to the genetic &/or physical ability to do such during other activities. 🔸Is it something I would encourage given the above...no, but I would suggest a knee angle as close to 180 degrees with minimal deviation from this raises the potential for better result. As mentioned in my previous post, this will create an effective force vector which allows for a greater contribution from the torso. However there are so many other variables that can influence outcome that even a great block doesn’t always yield the best outcome. Therein lies the unique challenge of our event. 🔹As ever, come back to me with questions or thoughts and I hope this was useful!
