Sports equipment can receive people's favor, in fact, it is mainly willing to be able to strengthen the body, can let us healthy health, below we will come and see.
Developed muscle, growth force
The body has skeletal muscle 639. The average man's muscle weight is about 40 of the weight. 45%, women account for 35%. The body is composed of muscles, bones and joints, ligaments, etc., so that the body can carry out a variety of complex movements. In other words, Sport Equipment the movements produced by the human body are derived from the contraction and stretching of skeletal muscles.
Sports equipment is one of the best ways to exercise your muscles. Because regularly engaged in equipment fitness, can make muscle fiber thickening, muscle of the capillary increased, Sport Equipment so that the muscle of the physiological cross-section of the increase, so that the muscle more substantial, full, developed. At the same time, the improvement of the central nervous system regulation will also lead to stronger muscles. Not only that, device fitness can also promote bone metabolism, improve its compression, tensile, torsion and other properties. In addition, the growth and development of joints and ligaments have a good promoting effect.
The muscles are composed of slender muscle fibers. Muscle fiber is the basic constituent unit of the muscle fibers. The number of muscle fibers in the body is generally five months after birth, Sport Equipment but the muscle fibers are relatively variable. In the process of equipment fitness, repeated and intense stimulation can make the basic constituent substance of the muscle fiber-protein synthesis increase. Sport Equipment These proteins can also synthesize new muscle fibers, which makes the muscle fibers thicker, that is, the muscle mass increases.
In normal conditions, only 30~270 capillary capillaries are open on the transverse section of the muscle of each square millimeter, and the rest are in a closed state. Sport Equipment In the exercise of equipment, there will be up to 200.013 million capillaries open. After a long period of training, the muscles of the open capillary state than usual greatly increased, coupled with the muscle fiber thickened, the muscle will naturally become developed and powerful.
Improve health and eliminate fat
Because the whole body is a unified whole, so each muscle is closely connected with other systems in the body. Regular equipment fitness, can significantly improve the circulatory system, respiratory system, digestive systems and the functioning of the CNS, Sport Equipment so that the overall improvement of physical fitness, health conditions to improve overall.
The circulatory system is composed of heart and blood vessels. Blood vessels throughout the body transmit oxygen and nutrients to all parts of the body, while the waste from the cell tissue activity is transported to the lungs, kidneys, skin and other areas. Device fitness can not only increase the volume of cardiac cavities, but also enhance the elasticity of myocardium and blood vessels, and can improve the contractility and vasodilation ability of the heart. It has been proved that the heart rate of the person who has been engaged in the equipment fitness for a long time can be kept between $number times. The average person's heart rate is more 70~90 times. Sport Equipment Because of the decrease of heart rate and the increase of cardiac rest time, the reserve ability of heart function is greatly improved. It is not difficult to see that a more affordable heart, to improve the human body's activities and adaptability, enhance metabolic function and immunity, how important role.
The lungs are the main organs of the respiratory system, which form the respiratory system with the respiratory tract. The lungs are composed of bronchi, blood vessels, and lung leaflets. Each lung leaflet has 400 alveoli. The lungs have a total of $number million alveoli. The human breath is the gas exchange between the alveoli and the capillaries around it. Adults Breathe $number times a minute in a quiet state and inhale about 0.2 ~ 0.3 liters of oxygen. Only 1/20 of the alveolar opening is enough to complete. During exercise, more oxygen is needed because of increased activity and metabolic enhancement. This requires breathing muscles to shrink more forcefully, absorb more fresh oxygen, and exhale more carbon dioxide. The effect of instrument body-building on respiratory function is to improve the breathing depth, and then the respiration frequency. In this way, the gas exchange volume of each breath increases, not only conducive to the rest of the respiratory muscles, but also improve the function of the respiratory system reserve, so as to ensure that the movement of gas exchange needs to improve the body's functional level.
Exercise Equipment Fitness can also make some defects in the body such as breast, scoliosis correction. Because of the various movements and methods of equipment fitness, Sport Equipment are designed according to the characteristics of human physiology structure, can give the body of various parts with great influence.
