1. How many muscles?
Total in the human body are fewer than 640 to 850 from the 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. Muscles have an average 40% body weight.

2. Top-most muscles
The most enduring of human muscle - the heart, the shortest - stirrups (it strains the eardrum in the ear). Its length - 1.27 millimeters. 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. masseter muscle (strength of their pressure can reach 100 kilograms) is very strong, as well as calves and glutes.

3. These different muscles
Muscles are not the same person. Therefore, they need to train in many ways, and recovery time, and different muscle groups differs. The fastest way to recover the triceps, the slowest - back muscles. This should be considered during training, the 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. Muscle Endurance
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 the doctors, "safety margin" of the average of the heart no less than 100 years. 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 - appeared in the cell membrane gap through which leaking calcium into the muscle cells.

5. Muscles and emotions
It is known that the movement of the facial muscles directly related to human emotions. In the beginning of the last century Russian scientist Ivan Sikorsky was the classification of facial expressions: the muscles around the eyes are responsible for the expression of mental phenomena, the 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. If they work from 29 to 34 muscle groups.

6. Muscle and genes
Amazingly, muscle training has an impact not only on the person, but also on his genes. In these modifications occur, which further helps muscle fibers to be ready for new loads. 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, the muscles adapt to increase metabolism.

7. Muscles and telepathy
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 abilities 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 one thinks intensely about something, the brain cells transmit impulses to all the muscles of the body."

8. Long palmar muscle
Only one out of six people on the ground kept both hands on the long palmar muscle. Some of them have only one hand. 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 transplantation material muscles.

9. Muscles and chocolate
Ironically, 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 epicatechin substance 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 chocolate can be considered as the prevention of heart disease and atherosclerosis.

10. Loss of muscle
Muscles do not last forever. After 40 years, they begin to actively combusted in the year a person begins to lose 2 to 3 percent of muscle tissue, after 60 years - up to 5%. Therefore, training in adulthood is not as important as in his youth.
