[Harm of mechanical treadmill] Which one is better, mechanical treadmill or electric treadmill? Mechanical treadmill damages the human body
Walking and running are the most natural human behaviors, For normal people, there is no need to master special skills. Running is an internationally popular aerobic fitness exercise, which is highly praised by the medical and sports circles.
However, due to environmental and climate constraints, it is impossible to run at any time. Therefore, there are many sports and rehabilitation equipment that simulate running or walking.
The early mechanical treadmills were artificially driven by the friction of the soles of the feet. At the same time, the gait is not natural enough to cause the muscle movement to be uncoordinated, and it feels stiff and rigid.
In contrast, the electric treadmill developed in recent years is more in line with the aerobic exercise. Because of its physiological characteristics, it has been loved by people, and gradually entered thousands of households, becoming an integral part of modern family fashion life.
The harm of mechanical treadmills
The mechanical treadmill drives the running belt through the human body, which seems to consume more energy on the surface, but due to the excessively concentrated backward torque on the ligaments, joints, etc., in order to make the running belt run backward during running Several key stress-bearing parts, this torsion is more likely to cause chronic fatigue of the tendon tissue in the stress-bearing parts, thereby breaking the local balance of this part of the tissue and damaging its health.
Turn exercise into a kind of fatigue, It is the nemesis against people’s interest in sports, and the main reason why most athletes fail to exercise.
More and more traditional treadmill users find that the more they exercise, the more their legs run. It’s not surprising that the more you exercise, the less energy you have in your joints. This kind of fatigue and side effects can seriously dampen your motivation to exercise.
The principle of electric treadmill
The electric treadmill drives the running belt through the motor, allowing people to run or walk passively at different speeds or gradients, greatly improving the comfort of exercise, and avoiding the adverse effects of outdoor exercise due to weather, environment and other unfavorable factors. The physical impact of the athlete reduces the possibility of sports injuries.
A person running or walking on a motorized treadmill is a systemic exercise because there is little or no stretching, and Compared with exercising on land, it can reduce exercise intensity and increase exercise volume, which has a very good effect on improving the user’s cardiopulmonary function, physical endurance and fat consumption.
Under the same exercise intensity, Electric running can consume 40% more calories per hour than other common aerobic exercise equipment, such as exercise bikes, rowing machines, mountain climbing machines, etc. Electric treadmills can also easily record exercise through integrated electronic equipment and control systems distance, consumption The heart rate test function can accurately display the current heart rate of the athlete, and exercise more scientifically and safely.
Therefore, an electric treadmill is a high-tech product that combines various technologies such as exercise physiology, ergonomics, and precise mechatronics. Running or walking on an electric treadmill is the best One of the forms of aerobic exercise.
Which is better, mechanical treadmill or electric treadmill
1. Comparison of mechanical and electric treadmill construction principles
The transmission system of the mechanical treadmill is composed of a conveyor belt cover, two fixed shafts at both ends of the conveyor belt are tightened, there is a shaft connected with the roller, an adjustable switch and a fixed frame. It is driven by the friction between the runner’s foot and the running belt.
The electric treadmill relies on the motor to drive the running belt to run, and the motor speed is controlled by the inverter to adjust the speed change during running. The control of the inverter is to process the signal of the sensor (voltage conversion), Then count, you can get the speed. From this point of view, mechanical treadmills are much more laborious and inconvenient than electric treadmills, so they are not easy to stick to.
2. Comparison of the health and safety of mechanical treadmills and electric treadmills for users
A mechanical treadmill can be said to be an active running device. Its power source is that the user generates backward thrust through his own arms, knees, ankle joints and related muscles, and pushes the treadmill to produce movement.
Using this way to exercise on a treadmill will cause several times greater injury than running in nature. Sports medicine experts say: running on the road, every kilometer you run , each foot has to hit the ground about 1,000 times, and the ankles, knees and buttocks are all oscillated, which can easily lead to muscle sprains or ligament strains. Running on a mechanical treadmill, the human body is not only the shock caused by its own weight, but also the ankle. The hips, knees, and hips, especially the tendons, are also subject to additional rearward torque to ensure that the belt moves backwards, and this additional torque is the source of sports injuries.
Because the electric treadmill is a combination of active and passive exercise, running or walking on the electric treadmill will save a leg-stretching action compared to ordinary people. The advantage of this is that everyone will feel very relaxed and happy when running on the electric treadmill.
In addition, the running boards and running belts of mechanical treadmills are of very general material, which cannot protect the joints, and have little shock absorption design. It is easy to cause damage to the knee and ankle joints of the exercisers; the electric treadmill has added a lot of technological content to make the training effect more scientific. small, reducing the possibility of sports injuries.
3. Comparison of the development trend of mechanical treadmills and electric treadmills
Mechanical treadmills belong to the sports products of the 1990s and are an earlier generation of running machines. With the replacement of treadmills, they were gradually replaced by electric treadmills, and now they have basically faded out of the market. The development and production of electric treadmills are based on mechanical treadmills, and it can be said that it becomes an upgraded version of mechanical treadmills.
4. The difference between mechanical treadmills and electric treadmills Price comparison
A mechanical treadmill costs only a few hundred yuan, and the cheapest electric treadmill costs about 2,000 yuan. The price difference is several times, but it is related to the driving force, basic structure and function and comfort of the treadmill. The motor, running board, running belt, heart rate test and other components of the electric treadmill are very different from the running belt and roller of the mechanical treadmill. Electric running also has different resistance and slope adjustment, and the display of data such as running kilometers, energy consumption, heart rate, etc., cannot be achieved by mechanical treadmills. As the saying goes, you get what you get for every penny, and it’s perfect here.
My summary:
Mechanical treadmill
Advantages: simple, solid, durable, economical Electricity, cheap.
Disadvantages: easy to cause sports injuries, poor exercise effect, has been eliminated from the market.
Electric treadmill
Advantages: more natural movement, and computer programs, computer speed control, more convenient exercise.
Disadvantages: In order to achieve the purpose of safety and comfort in modern electric running, the running belt is getting wider and longer, and the corresponding area is larger than that of mechanical running. It is recommended to choose the same size. Treadmill with wide running belt.
