it involves risks that need to be budgeted, but it is also true that we need to choose those technical-sporting lines of thought that allow us to optimize results while minimizing the dangers.
The example of the squat
For example, if we consider the exercise of the squat, in a condition of altered postural state, it can lead to a series of problems which, with the silent capacity of repeated microtraumas, would create problems that are often disproportionate when attributable to the cause that caused them. determined.
The squat in the healthy subject
A "normo-postural" subject, therefore who is in a condition of well-balanced loads on both feet, will have a fairly equal subdivision of the stresses given by the resistances imposed by the exercise.
In other words, if the subject weighs 100 kg and has a homogeneous distribution on both limbs - loading 50% of the weight on the side - he will weigh 50 kg on the right and 50 kg on the left. Using an overload of 100 kg placed on a barbell in the squat exercise, we will have a total of 100 kg on the left and 100 kg on the right. We could say, broadly speaking, that everything works as it should.
Therefore, if the subject enjoyed "adequate flexibility and all the skills necessary for" execution as correct as possible, he would obtain excellent results while remaining safe. But if the same person had a "postural alteration, even in minimal terms, was not aware of it and therefore continued to train, the problems would be almost inevitable - without wanting to be fatalistic.
The squat in the subject with body imbalances
For example, suppose that for a cause not apparently attributable to a specific event, this person had a rotation of one of the two hemibacins. This condition would lead to a functional (non-structural-anatomical) shortening or lengthening of a lower limb, which in the jargon of manual medicines are commonly defined as "false short leg or false long leg".
Given that this type of problem is not attributable only to the rotation of the pelvis, but also to imbalances of the knee and ankle or even of the upper part of the body, but for simplicity here we will limit ourselves only to describing only the essential concept, we will not go into the merits of all postural biomechanical alterations potentially responsible for this alteration.
Therefore, the problem of the pelvis almost always leads to a disproportion of the lower limbs, which involves an overload on the side of the "short leg" which, for compensation, will be forced to support the greater load.
The stress of the ankle under examination with respect to the lateral counter will be greater; the same goes for the knee and the hip. The sacroiliac joint will also be stressed more than the counter-lateral one, as well as the alteration of the curves on the sagittal plane of the spine will involve a greater overload of some points and so on up to the cervical tract.
All this, of course, in the standing position without exercise, without additional loads; imagine ourselves with the loads of the squat.
