For me it was news when still only went to study at the fitness trainer, how it increases bone density after exercise. I used to think that it only ... biochemical processes in the body - increases metabolism,improved health (in general, the semi-mythical sense) "dumped toxins" :)) and all at once it becomes better and more beautiful, and the bones too. But it turns out ... More on that below.
1. That is just how unpleasant becoming a human skeleton and posture due to a decrease in bone density with age:
2. Women, unfortunately,This process is largely due to accelerated outcome variables hormonal levels - throughout life and very much after menopause.Right, according to the illustrations in textbooks in the chapters on osteoporosis, usually marked age 60-65 years.
3. But a woman is 75 years old (!) - Incomparable Ernestine Sheppard (Ernestine Shepherd).Why do you think it did not affect these changes with age?
Well, besides a very strong back, which can keep the body. Not to mention the fact that with age is very difficult to collect at least some muscle and develop strength ... She has very good bone density. It is not appropriate to her age in the good sense of the word.4. Let's see how the bone tissue of age - a little later,or sedentary lifestyle - a little earlier.Upper picture - it's a good dense bone (not to be confused with the big bones on the hips .Lower picture - This is now bone of low postnasal very fragile and completely ready to fracture.
5. And the secret, in fact,is strength training. These mechanical effects on bone. When we do yoga exercises, the muscles contract. Muscle pulls the bone through the tendon in a particular location on the bone to which it is attached. The body begins to increase bone density in this particular location to the bone could not resist this thrust,in response to this load.The more regular power loads, the higher the weight lifted, the greater the density of the bone is forced to create in this place. Thus, the bone density will be greater in a fixing "working" the muscles than in a place where the muscles do not work.
6. Egeach vertebra of our spine bears a huge burden. And attached to the spine so many muscles: the main and most powerful skeletal muscle and small stabilizers. And when the bone in the spine becomes less dense as the picture on the left, the spine ceases to perform its supportive function,as in the right illustration.
7. Of course, in addition to the mechanical effect of the process of muscle contraction affecting the increase in bone density, there are also changes in the biochemical processes by which increased bone metabolism. And they also, to a greater extent, started strength training.Easier This can be explained as follows: the body does not need calcium if his body does not spend. As soon as he begins to spend something, it starts to consume and digest it. Works something like metabolism of different tissues and body as a whole.Keep in mind that the Calcium - is the main chemical component in the process of muscle contraction.When reduced muscle - calcium spent. When the tendon pulls the bone and bone density increases - calcium spent too. So he begins to digest only after this point. Lie on the couch and have the minerals and vitamins they rich or food - meaningless because they do not need the body, it does not spend them.
