The reason why fitness equipment is more and more popular is that it has a unique role that cannot be replaced by other sports. Through scientific, systematic and long-lasting fitness exercises, people not only enhance their physical fitness and cultivate their sentiments, but the biggest gain is that they can greatly improve their bodies. Obese people can become healthy; thin people can be burly physique; moderate people can make the body fitter
; deformed people can make the body shape corrected. Another feature of fitness equipment is that all men, women and children can participate in it, and everyone can benefit a lot.
Develop muscles, increase strength
The human body has 639 skeletal muscles. In general, the muscle weight of men accounts for about 40.45% of the body weight, and women account for about 35%. The human body movement organs composed of muscles, bones, joints, ligaments, etc., enable the body to perform various complex exercises. In other words, the various movements produced by the human body originate from the contraction and extension of skeletal muscles.
Fitness equipment is the best way to exercise muscles. Because regular fitness exercises can increase muscle fibers and increase 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 improvement of the central nervous system's regulatory functions, the muscles will become stronger and stronger. 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 role in promoting the growth and development of joints and ligaments.
Muscle is composed of thin muscle fibers. Muscle fibers are based on myofibril as the basic unit. The number of muscle fibers in the human body is generally determined four to five months after birth, but myofibrils are relatively variable. In the process of fitness equipment, repeated and strong stimulation can increase the synthesis of protein, which is the basic component of muscle fiber. These proteins can synthesize new myofibrils, thereby making muscle fibers thicker, that is, increasing muscle mass.
Under normal conditions, there are only 30 to 270 capillaries open per square millimeter of the muscle cross section, and the rest are closed. When exercising with equipment, as many as 2,000 to 3,000 capillaries will open. After a long period of training, the state of open capillaries in the muscles has greatly increased than usual. Coupled with the thickening of muscle fibers, 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 with other systems in the body. Regular exercise of equipment can significantly improve the functional level of the circulatory system, respiratory system, digestive system and central nervous system, so that the physical fitness can be comprehensively strengthened, and the health condition can be comprehensively improved.
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. At the same time, it transports the waste generated by the activities of cell tissues to the lungs, kidneys, skin, etc. to be excreted from the body. Fitness equipment can not only increase the volume of the heart chamber and increase the elasticity of the flywheel stationary bike myocardium and blood vessels, but also increase the contractility and vasodilation of the heart. Practice has proved that people who have been engaged in fitness equipment for a long time can maintain their heart rate between 60 and 70 beats per minute. The average person's heart rate is between 70 and 90 beats. Due to the decrease in the number of heartbeats, the rest time of the heart increases, which greatly improves the reserve capacity of heart function. From this, it is not difficult to see how important a heart that can bear a greater burden is to improve the body's ability to move and adapt, and enhance metabolic function and immunity.
The lung is the main organ of the respiratory system, and it forms the respiratory system together with the respiratory tract. The lungs are composed of bronchi, blood vessels and pulmonary lobules. There are 400 alveoli on each lung lobule. There are 500 to 700 million alveoli in the lungs. Human breathing is the exchange of gas between the alveoli and the capillaries around it. Adults breathe 12 to 18 times per minute in a quiet state, and the inhalation of oxygen is about 0.2 to 0.3 liters. This kind of workload requires only 1/20 of the alveoli to open. During fitness exercise, due to increased activity and increased metabolism, more oxygen is needed. This requires the breathing muscles to contract more vigorously, inhale more fresh oxygen, and exhale more carbon dioxide. The effect of fitness equipment on respiratory function is to increase the depth of breathing, followed by breathing rate. In this way, the amount of gas exchange per breath increases, which not only benefits the breathing muscles to rest, but also improves the functional reserve of the respiratory system, thereby ensuring that the gas exchange needs during exercise are met, and the functional level of the human body is improved.
Fitness equipment also has a good effect on the digestive system composed of the digestive tract and digestive glands. Because muscle activity consumes a lot of nutrients, it needs to be supplemented in time. At the same time, muscle activity can promote gastrointestinal peristalsis, stimulate the increase of digestive juice secretion, so that digestion and absorption capacity can be improved. Good appetite, natural appetite greatly increased.
Fitness with equipment, like all sports, is performed under the control of the central nervous system. Conversely, exercise can also improve the strength, balance and flexibility of the central nervous system. Many neurasthenia patients recover through fitness equipment.
Practice has proved that exercise and scientific diet are the best way to eliminate fat.
During exercise, the main source of energy supplied by the human body is sugar and fat. The exercise speed is fast, the intensity is high, and the duration is short, which mainly consumes sugar; the exercise speed is slow, the intensity is low, and the duration is long, which mainly consumes fat. Studies have shown that long-term, moderate-intensity exercise, fat energy can reach more than 40% of the body's total oxidation energy. If you want to use fitness equipment to lose weight, just follow the training principles of low load, light equipment, and long time, and persist for a few months, and you will surely receive very obvious results.
Beautify body shape, correct deformity
A beautiful body shape refers to the proportions, coordination and balance of all parts of the body. From the appearance point of view, the contours of the entire body and the main muscle groups have reasonable curves. Genetics tells us that a person's height and limb ratio are unlikely to change due to genetic influences, but the bust, waist, leg, and hip circumferences that are restricted by a person's weight and weight can all be changed. The "biggest feature" of fitness equipment is to "sculp" the muscles and fats that make up the body. For example, as long as a person with a slippery shoulder develops the deltoid muscles, the shoulders will be wider and the shoulders will be lifted, and the body shape will become more symmetrical; people with narrow chests and flat chests, through the training of the chest muscles, the chest will be better. It will increase and the three-dimensional sense will increase, and the body shape will naturally become thick and tall; people with slender leg muscles, as long as the leg training is strengthened, the body shape will become coordinated and burly. As long as those fat ladies or fat ladies who accumulate fat on the abdomen, buttocks and thighs, as long as they insist on aerobic training, the clear lines and light posture are no longer a luxury. As the body shape improves, the posture will also be beautified. For example, the so-called snake waist stretcher who is not standing or sitting, after a period of training, his posture and posture will naturally become upright, sitting and sitting.
Fitness equipment can also correct certain defects of the body, such as chicken breasts and scoliosis. Because the various movements and methods of fitness equipment are designed according to the characteristics of the human body's physiological structure, they can have a huge impact on all parts of the body. For example, people who have sagging shoulders insist on doing front flat lifts, side flat lifts, and back neck press exercises. By developing the deltoid and trapezius muscles, the shoulder defects can be compensated. A health care expert once said: "Machine fitness is the best medicine for people with localized muscle atrophy."
