Answer: When we lose the physiological curves of our back or lordosis, the weight falls vertically downwards, stacking the pressure directly on the vertebrae and making the latter take responsibility for all the weight of the others.
Explanation:
Our back, is composed of a series of segments called vertebrae, these segments join together to form a unique set called <u>the spine,</u> but this important and famous bone structure is not rectilinear, it is formed by a <em>series of curves </em>(lordosis and kyphosis ) that play a fundamental role in being able to efficiently support daily body weight.
With age, stress, lack of exercise, sedentary lifestyle ... t<em>hese curves tend to be lost or even reversed, generating lumbar rectification or loss of lumbar curvature, low lumbar hyperlordosis. </em>
This generates a bad adaptation in the distribution of weight and in the efficiency at the time of moving and supporting loads, which in the long run, will weaken and give back problems (disc dehydration, disc protrusions, herniations, facet osteoarthritis ... among others).
With correct lordosis, the weight does not fall directly on the intervertebral discs. The lumbar paravertebral musculature is more toned and predisposed to assume much of the body's weight. In addition, the weight is distributed more homogeneously over the vertebrae, causing the intervertebral disc to remain healthy and hydrated.
It is known, through different studies, that the discs withstand up to 4 times more pressure when there is no correct lumbar lordosis. The so-called lumbar curvature rectification or loss of physiological lordosis occurs.
