10 most interesting muscle facts

On this page there will be articles related to fitness in all its manifestations. About nutrition, weight loss, muscle gain, training and competition, and more.

200 muscles are included in the work with just one step. The heart – the most enduring muscle of the body – works constantly. Muscles grow and train, tons of sports literature are written about them. We will tell you the most interesting.

1. How many muscles? In total, the human body has from 640 to 850 muscles. During a simple walk, the body uses up to 200 muscles. Muscle tissue is 15% denser and heavier than adipose, so a trained person can exceed the weight of a full, but unsportsmanlike person of the same height. Muscles account for an average of up to 40% of body weight.

2. The most-most muscles The most hardy muscle of a person is the heart, the shortest is the stirrup (it strains the eardrum in the ear). Its length is 1.27 mm. The longest muscle of the human body is the tailor. The fastest muscle is blinking. Regarding which muscle of the body is the strongest, one can find different opinions. It is often said that the most powerful muscle is the tongue, but the tongue consists of several muscles, so this point of view is false. Chewing muscles are very strong (their pressure can reach 100 kilograms), as well as calves and buttocks.

3. Such different muscles. Human muscles are not the same. Therefore, they need to be trained in different ways, and the time for recovery and different muscle groups is different. The triceps are the fastest to recover, and the back muscles are the slowest. This must be taken into account during training, the muscles need rest no less than the load, since the growth of muscle fibers occurs due to the supercompensation effect. Full muscle recovery occurs only 48 hours after intense exercise.

4. Muscle endurance Endurance is the ability of a muscle to remain functional over time. The most enduring muscle of the human body, as we have said, is the heart. According to doctors, the “safety margin” of the average heart is not less than 100 years. Muscles begin to tire when glycogen runs out in them, and fatigue is also explained by the large amount of calcium in the muscles. Previously, it was believed that the main culprit of fatigue is lactic acid. At Columbia University, a study was conducted in which mice swam for three weeks daily and cyclists trained for three days. It turned out that after physical exercises in the chemical structure of the ryanodine receptor, which is responsible for muscle contraction, serious changes occurred – a gap appeared in the cell membrane through which calcium seeped into muscle cells.

5. Muscles and emotions. It is known that the movement of facial muscles is directly related to human emotions. At the beginning of the last century, the Russian scientist Ivan Sikorsky compiled a 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 acts of will, and feelings express all the muscles of the face. In 2011, scientists were able to discover that facial expressions of a person arise long before his birth. Even during the prenatal period, the child is already able to move his facial muscles, smile, raise his eyebrows in surprise or frown. The facial muscles make up 25% of the total number of muscles, 17 muscle groups are involved during a smile, and 43 during anger or crying. One of the best ways to maintain smooth skin on the face is through kisses. When they work from 29 to 34 muscle groups.

6. Muscles and genes It is amazing, but muscle training affects not only the person himself, but also his genes. Modifications occur in them, which later help the muscle fibers to be ready for new loads. In order to prove or disprove this, scientists from Aarhus University recruited a focus group of 20 volunteers and conducted a 20-minute aerobic exercise with them on an exercise bike. After the study, a quadriceps biopsy was taken from the subjects to see how the genes in their cells changed. It turned out that physical activity activates the genes related to the muscles. This is because cells store DNA using methyl groups. If they are removed, the gene information turns into enzymes and proteins, which are necessary for burning calories, gaining muscle mass and consuming oxygen. After the experiment, the number of methyl groups decreased in all participants in the study – that is, the muscles adapted to increase metabolism.

7. Muscles and telepathy A simple person is not able to establish control over all the muscles of the body, so irresponsible muscle contractions can serve for knowledgeable people as an indicator of hidden thoughts or conceived actions. High-level psychologists and telepaths can benefit from knowledge of these processes. Wolf Messing, one of the most famous telepaths, explained his phenomenal abilities not with magic, but with a thorough knowledge of the work of human muscles. He said: “This is not reading thoughts, but, so to speak,” reading muscles “… When a person thinks hard about something, brain cells transmit impulses to all the muscles of the body”.

8. Long palmar muscle. Only one out of six people on earth retained long palmar muscles on both hands. Some only have one on their hands. These muscle fibers are responsible for claw release in animals. A person, of course, does not need such a function. Long palmar muscles, therefore, are the rudiment used by surgeons, if necessary, as a material for muscle transplantation.

9. Muscles and chocolate Strange as it may seem, dark chocolate is one of the most healthy foods for the heart and for muscles in general. Studies at Wayne University in Detroit have revealed the effect of the epicatechin substance in dark chocolate on the growth of mitochondria in muscle cells. Scientists at the University of Aquila also conducted a study in which they gave test subjects one hundred grams of chocolate for 15 days and measured their blood pressure. During the experiment, people returned to normal pressure, blood circulation improved. Accordingly, moderate consumption of dark chocolate can be considered as the prevention of heart disease and atherosclerosis..

10. Loss of muscle. Muscles are not eternal. After 40 years, they begin to be actively burned, in a year a person begins to lose from 2 to 3 percent of muscle tissue, after 60 years – up to 5%. Therefore, training in adulthood is no less important than in youth.
