10 facts about muscles, after which it becomes clear how they work and work

1. How many muscles? H3> In total, the human body There are fewer than 640 to 850 muscles. During a simple walk to the body uses 200 muscles. Muscle tissue is 15% thicker and heavier than fat, so the trained person may exceed the total weight, but unsportsmanlike person of the same height. on the muscles on average up to 40% of body weight.

2. Top-most muscles h3> The most enduring human muscle - the heart, is the shortest - stirrups (it strains the eardrum in the ear). Its length - 1, 27 millimeter
.
The longest arm of the human body - tailoring. The fastest muscle -. Morgan

With regard to what kind of organism is the strongest muscle, you can find a variety of opinions. It is often said that the most powerful muscle - the language, but the language is composed of several muscles, so this view is false. Very strong are the masseter muscle (strength of their pressure can reach 100 kg ), as well as calves and glutes.

3. These different muscles h3> The muscles are not the same person. Therefore, you need to train them in different ways, and time for recovery and different muscle groups is different. The fastest way to recover the triceps, the slowest - back muscles. This should be considered during training, your muscles need rest as much load as the growth of muscle fibers is due to the effect supercompensation. Full recovery of the muscles occurs only after 48 hours of intensive exercise.

4. Endurance Muscle h3> Endurance - the ability of muscles to maintain performance over time. Most muscle endurance of the human body, as we have already said - the heart. According to estimates of physicians, «safety margin" of the average of the heart no less than 100 years old.

Muscles get tired, when they end, glycogen, and fatigue due to the large amount of calcium in the muscle. Previously, it was thought that the main culprit of fatigue is lactic acid.

The study was conducted by Columbia University, which three weeks mice swam daily and cyclists trained for three days. It was found that after exercise in the chemical structure of the ryanodine receptor, which is responsible for muscle contraction, significant changes have occurred - a gap appeared in the cell membrane, through which the filtered calcium into muscle cells
.

5. Muscles and emotions h3> It is known that movement of the facial muscles directly related to the emotions of man In the beginning of the last century Russian scientist Ivan Sikorsky was the classification of facial expressions:. The muscles around the eye is responsible for the expression of mental phenomena, muscles around the mouth - for the expression of the will acts, and feelings express all the muscles of the face
.
In 2011, scientists were able to discover that the human mimicry occurs well before his birth. Even during the prenatal period, the child is already able to move the facial muscles to smile, raise eyebrows in surprise or frown. Facial muscles are 25% of the total number of muscles, while smiling involved 17 groups of muscles, during anger or crying - 43. One of the best ways to preserve the smooth skin on face - kissing When you are working on 29. up to 34 muscle groups.

6. The muscles and genes h3> Amazingly, muscle training has an impact not only on the person, and its genes. They occur modification, which further helps muscle fibers to be ready for a new load.

In order to prove or disprove the scientists from Aarhus Universitetea scored focus group of 20 volunteers and carried with them a 20-minute aerobic exercise on a stationary bike. After studies in subjects quadriceps biopsy was taken to see how the changed genes in their cells.

It was found that exercise activates genes related to the muscles. This is because the cells retain DNA with methyl groups. If they are removed, the information is converted into a gene enzymes and proteins that are necessary for burning calories, a set of muscle mass and oxygen consumption. Following the experiment, all subjects reduced the number of methyl groups - that is, muscles adapt to increase metabolism
.

7. Muscles and telepathy h3> The common man can not establish control over all the muscles of the body, so the unconscious muscle contractions can be used for people who know an indicator of hidden thoughts or actions conceived. High-level psychologists and "telepathic" can use the knowledge of these processes.

Wolf Messing, one of the most famous telepaths explained his phenomenal ability to is not magic, but a thorough knowledge of the work of human muscles he said. "It's not mind-reading, and, if I may say so," reading muscles "... When a person is thinking intensely about something, the brain cells transmit impulses to all the muscles of the body. »

8. Long palmar muscle h3> Only one of the six people on the ground kept both hands on the long palmar muscle. For some they are only one of the hands. These muscle fibers are responsible for the issue of animal claws. A person understanding, such a function is not necessary. Long palmar muscle, thus, are rudimentary, surgeons used if necessary as a material muscle transplantation.

9. Muscles and Chocolate h3> Oddly enough, one of the most useful products for the heart and muscles in general is dark chocolate. Studies at Wayne State University in Detroit found influence contained in dark chocolate substance epicatechin on the growth of mitochondria in muscle cells. L'Aquila University scientists also conducted a study in which subjects were given a hundred grams of chocolate for 15 days and measured their blood pressure. At normal pressure, improved blood circulation during the experiment in humans. Accordingly, the moderate consumption of dark chocolate can be considered as prevention of heart disease and atherosclerosis.

10. Loss of muscle h3> The muscles do not last forever. After 40 years, they begin actively "burn" in the year of a person begins to lose 2 to 3 percent of muscle tissue, after 60 years - up to 5%. Therefore, in adulthood training are no less important than in his youth.
