Scientific selection method of treadmill

　　Traditional mechanical treadmills, commonly known as "passive" treadmills, are transitional products with "Chinese characteristics" developed to adapt to the national conditions at that time when my country introduced fitness concepts from abroad in the 1980s. The power source is that the user generates backward thrust through his or her arms, knees, ankle joints and related muscles to push the treadmill to produce movement.

　　On the surface, this method of exercise seems to consume more energy, but the sports injuries it produces are several times those caused by running in nature. Sports medicine experts say: when running on the road, every one kilometer of running, each foot has to hit the ground about 1,000 times, and the ankles, knees and hips are all affected. Being shocked can easily lead to muscle sprains or ligament strains. When running on a mechanical treadmill, in addition to the shock caused by the body's own weight, the ankles, knees and hips, especially the tendons, have to bear additional backward torque to ensure that the running belt moves backward. This additional torque is the source of sports injuries.

　　Because the torque is excessively concentrated in several key stress-bearing parts such as ligaments and joints, it is more likely to cause chronic fatigue in the tendon tissue at the stress-bearing parts, thereby breaking the local balance of this part of the tissue and damaging it. healthy . Turning exercise into a kind of fatigue is the nemesis of people's interest in exercise, and it is also the main reason why most athletes fail to exercise. More and more traditional treadmill users find that the more serious they are exercise , it is not surprising that the more you run, the thicker your legs will become, and the more you exercise the joints, the less powerful they will be.

　　Our running fitness requires methods. Choosing different running equipment and running methods will produce different fitness effects. If you are in elderly , for the purpose of strengthening muscles and bones, promoting blood circulation, medical rehabilitation, and extending life, it is recommended that you choose an electric walking machine, which is currently recognized by experts as the running equipment with the least sports injuries.

　　Various manufacturers have realized the seriousness of the problem and are accelerating the development of electric treadmills suitable for public fitness to accelerate the elimination of traditional treadmills. Currently, the popular household electric treadmills on the market range in speed from 0 to 18 kilometers. The electric walking machine is most suitable for medical rehabilitation, children and middle-aged and elderly fitness. Compared with traditional treadmills, this machine has the following obvious advantages. It is the most affordable public fitness and rehabilitation treadmill. Its folding and assembly are simple and convenient ； It only takes 2 seconds to fold the machine and only 1 minute to assemble the machine. This is the company's latest utility model patented product and is in a leading position in the industry. After opening the packaging box, you only need to gently lift the main column to the appropriate position with one hand, fix it with two knobs, and then you can use it. Loosen the knob and restore the main column, which becomes another horizontal folding method of the machine. You can place it in a lower place at home, taking up less family space. Reduce sports injuries ； The electric walking machine is a healthy electric treadmill with almost zero sports injuries. Medical experts say it can reduce the impact of traditional training methods on joints and avoid sports injuries. There are clear advantages over natural running. Using an electric walking machine can balance and eliminate the load on joints, which not only helps you lose weight and keep fit, but also helps the body recover after injury. There are many benefits.

　　When exercising, increase your steps, touch the ground with your back heels first, and move forward at the same speed in the direction of the running belt. Your hands and feet should imitate running movements: bend your arms at 90 degrees, use your shoulders as the axis, and swing them back and forth, so as to achieve a balanced exercise effect for all muscles in your body. Since the direction and speed of the running belt are consistent with the direction and speed of the footsteps, the torsion on the ligament is offset. Very comfortable to run. In this way, convalescents, children, and the elderly can maintain body balance and concentrate on exercising with peace of mind. If you want to increase the amount of exercise, you can also speed up the movement of your hands and feet.

　　For jogging purposes for rehabilitation and fitness, the heart rate should not exceed 110 to 130 beats per minute, and walking and jogging should be alternated. Jogging on the machine gives your heart and muscles a workout. This method will help middle-aged and elderly people gradually lose excess body fat. Therefore, slow running is especially suitable for elderly obese people.

　　When purchasing a treadmill, consumers should not blindly pursue the grade of the treadmill, nor should they buy old mechanical treadmills that have been eliminated because of fashion. Instead, they should choose a treadmill that suits their fitness needs based on their own fitness goals.
