Guest guest Posted December 31, 2001 Report Share Posted December 31, 2001 I'm definitely no authority here but I think I'm a good student of Westside so I can try to fill in until someone more reputable does. By vertical, the sideview is implied. During box squats, a ridiculously wide stance is encouraged so from the front, the shins are far from vertical. In fact, while we're speaking of box squatting, off the box, Louie says that you are supposed to bring your knees behind your heel. I can't do this yet but I've seen Matt Dimel do it in their video. His shins were actually past vertical. Dmitry Voronov Ontario, Canada Squats with Vertical Shins?

Science conventionally refers all positions and movements relative to three mutually perpendicular planes (and also axes), while anatomy also uses three basic planes of reference: frontal, sagittal and transverse. In other words, to be perfectly accurate, one has to define what is vertical with respect to all of these axes or planes. If we do so, then we will note that, unless one is standing perfectly upright with heels together, the shins are not vertical with respect to both the frontal and sagittal planes. Even then, the shins (tibiae?) are not necessarily entirely vertical in all people. As soon as one shifts the knees forwards or opens the legs wider, the shins no longer remain vertical in both of these planes. So, I would be most interested to hear exactly what all of these authorities mean by " vertical shins " before we take this topic any further. I do not wish to critique the advice of someone whose definitions have not yet been clearly spelled out. Note that, in addition to these " mutually orthogonal " planes and axes, science also defines torque or rotation with respect to these axes (where axes are located in the three planes), so that conventionally we describe and analyse position and motion in six dimensions, i.e., via the use of at least 6 variables (3 linear and 3 rotational). When one squats, any rotation of the lower extremities ( " the legs " ) creates torque around some or all of the joints and bones involved, so, if one is to examine thoroughly the action of the lower extremities during a squat, one has to consider what happens in all dimensions. Incidentally, rotation coupled with flexion of a joint, can significantly increase the risks of injury to the joint, which is a good reason not to simultaneously tilt and rotate the knees inwards (at least over a large range) under heavy loading (or to trying resist a hard tackle by struggling to keep one's feet firmly planted on the turf).

Off > subject - I enjoy this forum and am anxiously awaiting info on the next > Supertraining camp.> , this basically comes from poor interpretation of research conducted on the squat. The movement refers to forward movement of the knees during the descent of the squat. Now, some research has indicated that movement beyond 11-degrees forward takes away from the mechanics/leverage of the lift. And this is seen to mean that the shins need to remain vertical. Also coming into the picture are some good squatters that have their shins straight up and down while in the hole. Based on this " data " some feel that " you must squat with the shins vertical, " which is really nonsense if you look at how different most people are built and if you consider that the research indicates that your knees can move forward by up to 11-degrees. The box squat, however, is one of those training tools that hasn't been examined by scientists in any detail so exact info on that isn't available, suffice to say, you're still squatting and the general rules from the squat would seem to apply. -- Dan Wagman, Ph.D., C.S.C.S.

Guest guest Posted January 2, 2002 Report Share Posted January 2, 2002 After reading this thread for the past 11 or 12 arguments, I did a little non-scientific research this weekend. I had a Hi 8 mm. video camera, plumb bob and transit, three subjects with weights and squat rack. The three subjects we me (50+), 5'-7 " X 250#'s - best squat 357.5 Kg; my wife (44), 5'-3 " X 130#'s - best squat 160 Kg; and my son (14), 5'-10 1/2 " X 150#'s - best squat 102.5 kg. I set the bar up in the rack and we did three different squats with light and medium weight. During the squat, I set up the transit and Hi 8mm. video camera in line with the end of the bar, and suspended the plum bob from the end of the bar. I made an assumption that the most efficient squat was one in which the bar traveled in a straight line and in a vertical path along a plane perpendicular with the floor. I looked at the powerlifting squat, wide and conventional stance, the high bar " Olympic " squat and the front squat. I found several interesting things. 1.) All three subjects " racked " the bar comfortably in a position directly above the back 1/2 quadrant of the arch of the foot, in both the high bar OL squat and the Lower bar PL Squat (wide and narrow stance) and surprisingly in the front squat with a slight lean to the rear. The PL squat when racked properly was carried considerably lower on the back which resulted in a slight " lean " forward. 2.) All three subjects were then asked to squat the weight. Each lifter experienced an out of balance sensation if the travel of the bar fell outside of a path straight up and down from the original position of the bar. With the bar carried higher in the OL squat, the knees were driven slightly more forward than when the bar was carried lower in the PL squat. The knees were driven considerably more " forward " in the front squat than in the rear squat. 3.) As the bar was carried lower on the back in the PL squat, the work seemed to be more on the hip flexors, glutes and lower back, in the OL squat more in the quads, flexors and glutes; and the front squat, the quads and knees. If the knees were purposely driven forward, (pushing the bar forward of the path of the squat), more of the stress seemed to be placed on the knees and curiously the lower back. In the OL squat, when the heels were elevated and the knees driven forward, unless a strict upright upper body position was maintained, stress was placed upon the knees and quads. If the subject leaned forward, in this position, the stress was transferred to the lower back. Hmmmm....Could this mean that the travel of the path of the bar may be more important than whether the shins were perpendicular to the floor? I have been lifting weights for a while (mostly PL)and pushed the squat weight up to a raw 650#'s, (no belt, no wraps, no suit, but I did have a spotter, heh....I am not stupid). I found it very difficult to squat with any amount of weight without maintain a fairly perpendicular shin positioning. Since I do not use a squat suit nor have I used one in years, I am not sure what effect the suit might have on my form. I concluded that at least with myself, my wife and my son that the path of the bar is a more important aspect of the squat than whether the shins are parallel. It also seems that whether the shins are perpendicular or not so perpendicular is dependent upon the physical structure of the squatter. Of course again I realize that this is far from a scientific study and I have quite a lot of room for error.
