Earlier in the running circle, there were some big news that "running on the treadmill hurt my knee", which scared many friends who wanted to buy a treadmill. I can't completely deny this statement here. After all, an unreasonably designed treadmill will really hurt the joints of the trainers.

Usually, in order to avoid sports injuries, a good running opportunity has a very scientific shock absorption system, which provides more buffer for runners than road running, so a good shock absorption system can better protect the knees and relieve the pressure on the knees and ankles. The so-called good shock absorption system does not mean that it is particularly soft to step on, but through the use of composite materials, it tries to make runners run more comfortably without losing their sense of running.

The treadmill drives the belt through the motor, and then drives the running belt through the roller. This series of electromechanical and mechanical operation processes will inevitably produce certain noise. When a runner is training, the noise will be amplified by the sound of footsteps, footsteps and running belts, plus the sound of the motor doing work. In order to prevent the noise of runners from disturbing neighbors too much and interfering with the work and study of cohabiting families and lovers, it is stipulated that the standard requirement of a brand-new treadmill that has just left the factory is to run on an open platform (5 kilometers per hour), and the sound measured within the range of treadmill 1 meter is not higher than 70 decibels, which is also the protection standard of living environment noise. This has many requirements for the motor design of the treadmill.

2. Track domain

When ordinary people run, the pace of their feet is about the same as the shoulder width, so the wider the running track, the greater the activity space; The longer the running belt, the greater the pace change and the space for advancing and retreating. According to ergonomics and referring to the horsepower of the motor, 45cm( 17

3/4 inch) width X 130cm(50 inch) length should be a suitable reference area, and then it should be increased or decreased according to the individual's actual situation.

Theoretically, under the same horsepower, it is more suitable to choose a treadmill with a large runway area and a small space occupied by the whole machine.

3. Vertical pipe specifications

The pipe string connecting the electronic dial and the treadmill is called a riser (see the picture above). If the vertical board is thick and firm, the more stable the overall structure of the treadmill is, the safer it will be to run.

4. Other details

1) displays the information of the dashboard: whether it includes speed display, timing, running distance, slope display, heat consumption, etc. In addition, a good treadmill also provides a demonstration of the exercise plan, so that you can better understand the situation during the exercise.

2) Convenient and simple operation buttons: start, stop, speed adjustment, slope adjustment, and exercise course selection (such as fat burning mode and heart rate maintenance mode). A good treadmill provides a direct choice of exercise programs.

3) Safety magnetic lock function in case of emergency power failure.
