What are the benefits of fitness 2 1 to promote the growth and development of teenagers?

Regular exercise can promote the growth and development of teenagers, because bones and muscles need a lot of blood during exercise, which contains a lot of oxygen and nutrients, and the metabolism is in a vigorous state; On the other hand, the epiphyseal cartilage is constantly rubbed and squeezed during exercise, and the cells are constantly divided and ossified, which makes the bones thicker and longer, so people who insist on exercise grow taller and their limbs develop more symmetrically than those who don't like exercise.

2, delay aging

Insisting on exercise can regulate the function of nervous system, accelerate nerve reflex, make the heart beat vigorously, increase blood output and enhance muscle strength; Moreover, exercise needs more oxygen, so regular exercise can exercise the respiratory muscles, delay the aging of the respiratory system, promote the internal metabolism and visceral function of the body, and effectively delay aging.

3. Make people happy

Regular exercise can keep the balance between excitement and inhibition in cerebral cortex, and also increase norepinephrine in blood and brain. Norepinephrine can strengthen the connection between the brain and nerves in various parts of the body and improve the excitability of the nervous system. When norepinephrine increases in the blood, people's mood will become happy.

4. Enhance cold and heat resistance.

The human hypothalamus has a thermoregulation center, which can keep the balance of heat production and heat dissipation in the body according to the changes of external cold and heat. Insisting on exercise can improve the sensitivity of the thermoregulation center, regulate the body temperature faster and more accurately, and thus enhance the human body's ability to resist cold and heat. Long-distance running, cold bath, sunbathing, swimming, skating, skiing and other sports are all very helpful for the exercise of cold and heat resistance.

5. Make people smart

Exercise can effectively increase the weight of the brain and the thickness of the cortex, making it more active and functional. When people exercise, the brain cells that manage exercise are often in the process of rapid excitement and inhibition. After exercise, it can improve its adjustment function, reaction speed, flexibility and accuracy. Furthermore, regular exercise can mobilize the enthusiasm of brain cells, give full play to their potential, release enkephalins and endorphins in the brain to participate in metabolism, enhance understanding and memory, and make people smarter.

6, bodybuilding figure

When you exercise, your whole body muscles will move, and you can shape a beautiful figure through muscle changes. In the process of muscle contraction, from quantitative change to qualitative change, a series of changes occur, and muscle fibers increase and thicken. Among them, the contents of sugar, protein and minerals gradually increase, the muscle volume increases, the surface bulges, and it is more plump and powerful.

7. Improve people's mental outlook

Insisting on exercise can improve the body's immunity and improve people's mental outlook. Because exercise consumes a lot of energy, it needs to speed up the metabolism in the body to supplement it, which will speed up the heartbeat, deepen breathing, strengthen digestion and absorption, promote vigorous blood circulation and meet the urgent needs of the body. In this way, all tissues and organs in the body can maintain vigorous vitality, significantly enhance their functions, improve their speed, strength, agility and other qualities, coordinate their actions and be full of energy.

8. Prevention and treatment of diseases

Persisting in exercise can enhance the disease resistance of nervous system, enhance the functions of heart, lung, endocrine and other internal organs, make metabolism vigorous, improve nutritional status, enhance the hematopoietic function of the body, increase red blood cells and white blood cells in the blood and antibodies against germs, and enhance the resistance to various diseases and infectious diseases. At the same time, during exercise, due to the improvement of metabolic level, indigestion, obesity, hypertension, arteriosclerosis and coronary heart disease are also prevented. In addition, exercise can also enhance the working ability of the thermoregulatory center in the hypothalamus, so that it can regulate the body temperature sensitively and accurately, and prevent diseases such as colds, frostbite, heatstroke and thermal spasm.
