Yoga (Sanskrit yoga) is a mixed word of Hindi and Germanic, which means "yoke of cattle" in English, that is, restraint and control. The original meaning of yoga is "correspondence", that is, how to achieve spiritual consistency and spiritual understanding through introspection, self-control, appearance of the world and coordination with everything.
Yoga has been developed for more than 5000 years. It was originally a way for Indian ascetic monks to practice, but now it has become a popular way for mass fitness. Because in a highly competitive and developed modern society, people are faced with more pressures from all sides, and they often feel anxious, irritable and tired.
Due to the application of high technology, the time and physical consumption of productive labor are reduced, which leads to the decline of the function of some organ systems in human body. The repetition of a single action for a long time makes people's body in a sub-health state. All this makes people have a strong idea of returning to nature and tranquility.
I need a way to completely relax my nervous nerves under high pressure. Yoga is the best choice to solve this problem. This is nothing new. As an ancient sport, it stands out among many sports with its unique charm and is loved by more and more people.
Yoga integrates stretching, breathing and meditation, which enables people to achieve the state of unity of body and mind. Regular exercise can adjust the balance of hormones in various glands in the human body, relieve nerves in the body, improve sleep, eliminate fatigue, and keep people peaceful, calm and young. It can also activate the spine, improve the deformation of the spine, correct slight disc dislocation (such as hunchback, neck probing and other bad postures), and at the same time strengthen the strength of major muscle groups, thus achieving the role of fitness.
Yoga is not only a body art, but also a philosophy of life. It integrates medicine, science and philosophy, and it is not only intellectual, perceptual, but also rational in practice.
The weight loss principle of yoga
Breathing: A unique breathing training method in yoga practice, because breathing is deeper and longer than usual, which completely increases the supply of oxygen, purifies blood and strengthens lung tissue.
When breathing correctly, breathing is calm and the excitability of cerebral cortex is low, which can effectively regulate the brain that controls appetite and prevent overeating. This is equivalent to the effect of fenfluramine in diet pills, which acts on the satiety center of the feeding center, reduces the excitability of nerves, reduces the excitability of people to food and the impulse of overeating, and has no side effects brought by drugs.
In the process of breathing, the diaphragm moves up and down, which improves the massage and self-regulation ability of internal organs, strengthens the peristalsis function of intestinal tract and effectively prevents constipation, which is equivalent to the role of laxatives.
Breathing method accelerates blood circulation with its unique breathing exercise mode, and the amount of oxygen delivered by blood in unit time can be increased, thus creating conditions for aerobic metabolism during exercise.
Because some special breathing methods in yoga breathing require continuous movement of abdominal muscles, such as compound breathing and pump breathing, it can effectively exercise the abdomen, mobilize abdominal fat and play a role in losing weight.
Posture method
First of all, yoga posture is a kind of whole-body exercise, which not only moves to the large muscles and muscle groups of the body, but also moves to the small muscle groups of the body, thus avoiding the disadvantage that various parts of the body can not be exercised due to excessive local burden in general exercise, so that some parts of the body that are easy to accumulate fat can also be effectively stimulated, such as women's waist, buttocks and thighs, men's waist, abdomen and chin, thus avoiding the formation of local "fat".
In addition, yoga posture exercises make muscles stretch longitudinally as much as possible, which can reduce fat around cells, improve material circulation, promote cell division and renewal, and adjust the metabolic rate that slows down with age.
Maintaining the speed of body metabolism can consume excess fat in the body, reduce body fat weight, lower body mass index, and achieve the purpose of losing weight and controlling weight.
Yoga movements are mostly slow and continuous stretching with low intensity. The contraction modes of skeletal muscle include centripetal contraction of active muscle, eccentric contraction of antagonistic muscle and isometric contraction of active muscle and antagonistic muscle. The tension during contraction is small and the speed is slow, so the muscle fibers are mobilized in turn during exercise, and the mobilization of slow-moving units is mainly the contraction of slow muscle fibers. Long-term practice of yoga will cause adaptive hypertrophy of slow muscle fibers and disuse atrophy of fast muscle fibers. As we all know, slow muscle fibers are thin in diameter and small in volume, while fast muscle fibers are thick, so the overall effect of muscle adaptation brought by yoga exercise is to reduce muscle volume.
Yoga exercise lasts for a long time, and a complete exercise takes more than 1 hour. It belongs to the exercise that is mainly aerobic metabolism in the energy supply continuum.
In yoga practice, the role of phosphate system and glycolysis system is relatively limited, resulting in less fatigue substances such as lactic acid, and the exercise fatigue and fatigue are relatively light. Practitioners can practice for a long time with a happy mood and relaxed feeling.
In addition, in the process of yoga practice, muscles always contract and relax alternately, which increases the amount of blood flowing back from veins in muscles and ensures the full perfusion of muscle blood during practice. In addition, yoga emphasizes breathing, so that the muscles of practitioners can get enough oxygen for aerobic metabolism.
The energy source in yoga is basically the aerobic oxidation of fatty acids and blood sugar. Because of the long exercise time, many actions are repeated continuously, which consumes a lot of energy, and the oxygen supply is sufficient to ensure aerobic oxidation, so it can effectively activate the solid fat in the body and reduce blood sugar and blood lipid.
ponder
The process of meditation requires "peace of mind" and pays attention to "intention", which has a good training effect on brain activity and improves the sum effect of nervous system. When meditation reaches a certain state and changes the body function, the effect of relaxation during meditation is three times that of sleep.
When people completely relax and rest, the respiratory rate drops, blood pressure drops, blood oxygen saturation increases by three times, and oxygen consumption drops.
People can fully relax in meditation, and the brain and internal organs enter a state of rest, which can trigger hibernation genes in the body and consume fat and energy in our body. Everyone knows that many animals hibernate, such as bears and snakes.
Their hibernation is a physiological response to changes in the external environment. They consume a lot of fat during hibernation. Because they don't eat when they hibernate, there is almost no sugar consumption. Fat decomposition is almost the source of all energy.
It is reported that some researchers are now working on developing hibernation genes, hoping that in the future, we can lose weight and consume excess fat during sleep, and easily get the body we like during sleep.
