The biologists finally figured out why physical exercises have a rejuvenating effect on the body. Studies have been performed on humans and not on animals. The studies found that performing exercise, aktiviziruyutsya power stations of the cell – the mitochondria. In addition aktiviziruyutsya and genes responsible for their work. This leads to the fact that even decrepit old men become one and a half times stronger, and younger.

The mitochondria are the power plants of cells. They are responsible for the synthesis of the main energy carrier in cells – ATP. In addition, the mitochondrion is the only organelle that has its own genome. In different cells of the body is different the number of mitochondria, it all depends on the energy needs of the body. The accumulation of mutations in the genome of mitochondria and disruption of their function, most commonly associated and the aging process.

Systematic physical exercises to restore the functions of the energy stations of the cell-the mitochondria is determined by canadian scientists from the Institute of ageing Tank in Ontario.

For the experiment chose people of two different age categories. The group of "young,"and included men and women aged 20 to 35 years, senior group – people from 65 to 70 years, all participants had not any complaints about their health. Before the experiment, all participants were about the same food, did not use any medical drugs that could at least like something to affect the function of mitochondria, not fond of sports. In the beginning of the experiment all participants took samples of muscle tissue. Then 25 people from the senior group for six months was engaged in power exercises. The exercises were performed on machines available in any fitness centers. Training was conducted 2 times per week, they include 30 cuts aimed at different muscle groups, this chart is used in many workouts. At this time, the people of the"younger" group were not engaged or anything.

After six months all participants took again to the analysis of the muscle tissue. Thoroughly studied how the active genes responsible for mitochondrial function. So as we all know that the failure of mitochondria is the primary cause of aging. As soon as the work of mitochondria deteriorates, losing muscle mass, deteriorating the activity of the muscles, it has long been proven by scientists. Conducting the study finally appeared the opportunity to compare how active genes in muscles of young and elderly people.

As suggested earlier, the work of mitochondria in muscle cells of old people before the training was low. But the most surprising was the fact that after training, the activity of genes recovered.

Mainly those which are so necessary for the mitochondria to work properly. Again measured muscle strength, up to the beginning of classes the muscles of older people were 59% weaker than muscles of young people, after six months of training, this result dropped to 38%. From this we can conclude that older people were stronger by almost half.

The doctor said Mel "We did not expect that the activity of genes in the cells of the muscles will increase. We assumed that at this age, such obvious changes to happen can't." As said Dr. Melov, this study proves that physical activity necessary to restore the operation of mitochondria, and rejuvenate the entire body, improve health.

The uniqueness of this experiment is that the study was performed on humans, not laboratory animals (rats, mice), and that is emphasized by the authors. Again, this study shows all men that they can correct the approach of old age, or to stop this process altogether.

The log shows a detailed report on this research. However, this is not the limit, and the authors not want to stop. Next in the plans of scientists to figure out how changing the activity of genes and mitochondrial function in other tissues and organs of the human body during regular strength training sessions.
