So I've been doing some research into the biomechanics of the squat and one thing that's always surfaced is the topic of a partial vs. deep motion.
(Assuming partial = above parallel thighs & that deep = hips below patella, thighs just below parallel)
All these articles have been telling me that shear force at the knee reaches its max at the lowest point of the squat, and that when you go beyond parallel, you are risking injury to the menisci and cruciate ligaments.
But then on the other hand you have a lot of people saying that the lower you go the better, and that it is actually safer than just going parallel b/c the hamstrings are activated more and take some load off the quadriceps.
I'm completely confused. Can the veterans here please advise?
