Squat
"A biomechanical model for estimating moments of force at hip and knee joints in the barbell squat" Bruce Ross
"It ... seems appropriate to question the efficacy of the squat as a general exercise for developing leg strength. In particular the wisdom of its use in preparing athletes for participation in sports that themselves have high incidence of back and knee injury must be doubted."

"Biomechanics of the knee during the squat exercise"
"The purpose of this paper is to review the effect of squatting in a weight training program. Such issues as co-contraction within the thigh muscles, open verses closed kinetic chain exercises, torque at the knee and proper form will be discussed."

"Squat exercise - should you prescribe the squat as a rehabilitation exercise? Here's a review of the evidence"
"very deep squats involve high compression forces making them unsuitable for patients suffering with knee injuries.

"Squat research review"
"if you want to be able to jump high or leap long in your sporting activity, you would be wise to focus very heavily on squat training, since it correlates very, very well with both these attributes."

"Squatting and the implications of technique on muscle function" David Woodhouse
"Increased lifting speed causes higher maximum, and greater variation in, shear and compressive force in the knee and spine. This is because a faster descent requires greater deceleration forces from the knee and hip extensors in order to slow and stop the weight at the bottom of the descent ."

"Squatting exercises: How safe is squatting? Does it injure the knees or even the spine? Here's an exhaustive review of the research" Owen Anderson
"when individuals hurt themselves while squatting, it may not be the exercise itself which is harmful - but the manner in which the squatting is performed."

"Squatting exercises: How safe is squatting? Does it injure the knees or even the spine? Here's an exhaustive review of the research - Part 2" Owen Anderson
"Although incorrect utilization of the squat exercise during training can certainly heighten one's chances of getting hurt, correctly performed squats are not only safe, they also can dramatically improve functional leg-muscle strength, jumping ability, and running speed. "

"The role of synchronised hip and knee joint angles in efficient squatting " Bruce Ross
"I suspect that many people fall into the habit of excessive forward trunk lean from observing power lifters. However a typical power lifter is probably someone with a very strong back who is focussed on muscling up maximum weight without being concerned as to whether they are adequately exercising their leg extensors."
