Treadmills that use electricity can automatically adjust their speed. It is labor-saving to dig with a machine, and it is easy to slip when it is fast. Machines without electricity are controlled by people, which is laborious and safe.
brief introduction
The reason why it is best for middle-aged and elderly people to use machinery for running exercise is simple. Plug-in treadmill is an auxiliary running exercise tool, which has certain risks. When the running rhythm can't keep up with the treadmill a little, there is a danger of passive fall. Even if there is a safety rope, it will inevitably fall, and because the middle-aged and elderly people have poor balance, they are more likely to fall, so it is better to use machinery.
Running on an electric treadmill is easier than running on a non-electric treadmill. The safety of non-electric treadmills is higher than that of electric treadmills. For sports, running on an electric treadmill and a non-electric treadmill consumes basically the same amount of calories as long as the mileage and time are the same.
The advantage of non-electric treadmill is that it does not interfere with aerobic jogging, fast sprint, slow walking and stop running. Runners don't need to touch any buttons, and there is no interference. They can control their running speed and state only by changing their center of gravity forward or backward. The disadvantage of non-electric treadmills is that non-electric treadmills need runners to use more core muscles to control their bodies in order to play a stable and coordinated role.
