A friend of mine and I were discussing squats the other day. He was saying that going down to parallel is bad for the patella tendon. And I was saying that as long you’re doing a PL squat (i.e. sitting back, tibia stays as vertical as possible) the stress on your patella is the same the whole time throughout the squat - at the top and at parallel - as long as you keep your lower leg as vertical as possible.
I’m pretty positive I’m right but I was just wondering if somebody could help me out in finding the references proving this. Thanks.
(and if I’m wrong, please enlighten me)
