I did a search (on several journals as well), but to no avail -
Can anyone point me to a specific study showing knee angle speeds greater than 360 degrees/sec?
I’ m doing research, and I am trying to expose what I believe is the not relevant way we test athletes on a isokinetic open chain leg curl-type machine and then claim it is related to sprinting…
OK, I know this is a shot in the dark, but can anyone lead me to water?

and there are plenty of others…
Actually sorry just reread your post these studies show speeds greater than 360 degree at the hip more so than the knee… so may not be what you are after…
Some discussion on the subject.

You might also look into the early works (late 90’s) of Derek Kivi. Perhaps the results are viewed differently today. However there might be some supporting works that are referred to.
Thanks , TMSSF
I appreciate it… this helped!
You are certainly correct about the machines. They are not just irrelevant but dangerous and have prolonged and/or screwed up the rehab for individuals for decades . I suppose I shouldn’t complain about the machines since they’ve created the scenario that has sent a number of NFL players my way to fix what they’ve screwed up.
