A lot of truth in this!

"all gene expression not significantly different from the preexercise levels by 24 h postexercise"

therefore the muscle is repaired in 24hrs.(I think )

I have great difficulty with this statement. As I understand it, taking the squat such that it subjects the knee joint to an acute (i.e. less than 90 degree) angle puts a vastly increased strain on the knee joint (as opposed to a greatly increased muscular load). I never take my squats lower than parallel because on the occasions I have done, I got some serious warning signs from my knee[s]. It just didn't feel right. Thinking about it intuitively, it is not a natural position for your body to be under load! You do not normally operate with your legs bent double completely over.

Haven't quite a lot of people seriously damaged their knee joint from squatting excessively low? It does not seem biomechanically advisable, long-term, to subject the knee joint to this stress. And it is worth pointing out that a lot of the Olympic powerlifters who do massive snatches, effectively going into a super-low squat during the lift, have also experienced serious knee injuries. Not good. On a similar vein, I heard that it is also not advisable to do military presses behind-the-neck, as it can effectively force the shoulder joint to pull out.

Opinions/experiences?

Aren.

I love hearing things about full squats, I've always used them and been told I will damage my knee's. Mostly by guys that boast about there half squats and the weights their lifting. The funny thing is I'm one of nearly all the guys I know with no knee problems. I believe in full movements with all exercises, if they are done correctly and the amount of weights used are not rushed into, you will have no problems. As for Olympic lifters, any top level athlete that is pushing his body to the max will have injuries or problems. Footballers and other athlete's have problems with knee's and that don't squat heavy weights.

I wish I could find the info from last year, It was a report from some research or another suggesting that full squats actually help lubricate the knee joint more effectively than partial squats. As for natural positions most weight training done is not natural. Examples being Bench press and tricep extensions but squats are.

We are naturally hunter gatherers so bending and carring is some of our most natural ways of doing things. If you look at people that are naturally strong they normally have good legs back shoulders and biceps.
