What are the functions and benefits of fitness equipment?

　　The main reason why fitness equipment is favored by people is that it can strengthen the body and make us healthy. healthy It’s healthy, but many people may not know how to maintain fitness equipment? How to maintain common treadmills? Let’s take a look with everyone below.

　　Develop muscles and increase strength

　　The human body has 639 skeletal muscles. The average man's muscle weight accounts for about 40% of his body weight. 45%, women account for about 35%. The human body's movement organs, which are composed of muscles, bones, joints, ligaments, etc., enable the body to carry out various complex movements. In other words, all kinds of movements produced by the human body originate from the contraction and extension of skeletal muscles.

　　Equipment fitness is for muscles exercise one of the best methods. Because regular exercise with equipment can thicken the muscle fibers and increase the capillaries in the muscles, thereby increasing the physiological cross-section of the muscles and making the muscles stronger, plump and developed. At the same time, due to the central nerve Improvements in system regulation will also lead to stronger and stronger muscles. Not only that, fitness equipment can also promote bone metabolism and improve its resistance to compression, tension, and torsion. In addition, it also has a good promotion effect on the growth and development of joints and ligaments.

　　Muscles are made up of thin muscle fibers. Muscle fibers take myofibrils as the basic unit. The number of muscle fibers in the human body is generally determined four or five months after birth, but myofibrils are relatively variable. During the process of equipment fitness, repeated and strong stimulation can increase the synthesis of protein, the basic component of muscle fibers. These proteins can synthesize new myofibrils, thereby thickening the muscle fibers, that is, increasing the size of the muscle mass.

　　Under normal conditions, only 30 to 270 capillaries are open per square millimeter of muscle cross-section, and the rest are closed. When exercising with equipment, as many as 2,000 to 3,000 capillaries will be opened. After a long period of training, the number of open capillaries in the muscles is greatly increased than usual. In addition, the muscle fibers become thicker, and the muscles will naturally become developed and powerful.

　　Improve health and eliminate fat

　　Because the whole body is a unified whole, every muscle is closely connected to other systems in the body. Regular exercise with equipment can significantly improve the functional level of the circulatory system, respiratory system, digestive system and central nervous system, thereby comprehensively enhancing physical fitness and improving overall health.

　　The circulatory system is made up of the heart and blood vessels. The blood in the blood vessels throughout the body transports oxygen and nutrients to all parts of the human body, and at the same time transports waste products produced in the activities of cell tissues to the lungs, kidneys, skin Excreted from the body. Equipment fitness can not only increase the capacity of the heart chamber, enhance the elasticity of the myocardium and blood vessels, but also improve the contractility of the heart and the ability to relax the blood vessels. Practice has proved that people who have been engaged in equipment fitness for a long time will heart rate It can be maintained between 60 and 70 times. The average person's heart rate is between 70 and 90 beats. As the number of heartbeats decreases and the rest time of the heart increases, the reserve capacity of the heart function is greatly improved. It is not difficult to see from this that a heart that can bear a larger load plays an important role in improving the body's mobility and adaptability, and enhancing metabolic function and immunity.

　　The lungs are the main organ of the respiratory system, and together with the respiratory tract, they form the respiratory system. The lungs are composed of bronchi, blood vessels and pulmonary lobules. There are 400 alveoli in each lung lobule. There are 500 to 700 million alveoli in the lungs. Human breathing, that is, gas exchange, takes place between the alveoli and the capillaries surrounding them. Adults breathe 12 to 18 times per minute in a quiet state, and inhale about 0.2 to 0.3 liters of oxygen. Such a workload only requires 1/20 of the alveolar opening to be completed. During fitness exercises, due to increased activity and enhanced metabolism, more oxygen needs to be supplied. This requires the respiratory muscles to contract more vigorously, inhaling more fresh oxygen and exhaling more carbon dioxide. The impact of equipment fitness on respiratory function focuses on improving breathing depth, followed by breathing frequency. This increases the amount of gas exchange in each breath, which not only helps the respiratory muscles rest, but also improves the functional reserve of the respiratory system, thereby ensuring that the needs for gas exchange are met during exercise and improving the functional level of the human body.

　　Beautify body shape and correct deformities

　　A beautiful body shape refers to the well-proportioned, coordinated and balanced body parts. From the appearance point of view, it means that the lines and outlines of the entire body and major muscle groups have reasonable curves. Genetics tells us that a person's height and limb proportions are unlikely to change due to the influence of genetic genes, but a person's weight and the chest circumference, waist circumference, leg circumference, and hip circumference restricted by weight can all be changed. The "biggest feature" of equipment fitness is to "sculpt" the muscles and fat that make up the body shape. For example, as long as people with sloping shoulders develop their deltoid muscles, their shoulders will become wider, their acromions will be raised, and their body shape will become much more symmetrical. ； For people with narrow chest and flat chest, through chest muscle training, the chest will be enlarged, the three-dimensional sense will be enhanced, and the body shape will naturally become thicker and taller. ； For people with slender leg muscles, as long as they strengthen their leg training, their body shape will become coordinated and tall. For those fat men or fat ladies with fat accumulation in the abdomen, buttocks and thighs, as long as they insist on aerobic equipment training, clear lines and a light figure are no longer a luxury. As your body shape improves, your posture will also be beautified. For example, the so-called snake-waisted and hip-drawn people who are neither standing nor sitting, will naturally become straight-chested and straight-backed, walking and sitting upright as long as they undergo a period of training.

　　Equipment fitness can also correct certain body defects such as chicken breasts and scoliosis. Because various movements and methods of equipment fitness are designed according to the characteristics of the human body's physiological structure, they can have a huge impact on various parts of the body. For example, those with scapula ptosis should insist on doing exercises such as front raises, lateral raises, and behind-the-neck presses to make up for shoulder defects by developing the deltoid and trapezius muscles. A health care expert said: "Equipment fitness is the best medicine for people with local muscle atrophy. ”

　　Gym strength equipment and aerobic area maintenance and upkeep

　　Check the wire rope for broken wires. Check whether the screws of each part of the instrument are loose, whether each part is shaking or not hidden. If found, tighten it immediately. If the problem cannot be solved, notify the manufacturer for processing.

　　During use:

　　Listen carefully to see if there are any normal sounds. If you find any, stop using it immediately to prevent greater damage to the machine, and call the manufacturer for repairs.

　　After use:

　　Clean the appearance of the instrument with a slightly damp cloth, especially the parts with sweat stains. Clubs that have the conditions can wipe all parts of the instrument with water-based wax after wiping to avoid paint peeling and rust. Wipe the weight guides and slide rails with water-based wax at least once a week. Electronic equipment - treadmill A treadmill is a fitness equipment device that simulates running and walking. Running and walking are systemic aerobic metabolic exercises. The power of the treadmill is that the power drives the roller to move the rubber belt, and people run on the rubber belt. The exercise load can be adjusted by adjusting the speed of the rubber belt.
