Max. user weight
The highest weight of an athlete, at which the treadmill is able to work indefinitely for a long time (at least during the warranty period) without negative consequences. Most modern models have a "weight category" of the order of 150 kg and even more, which allows them to be used even by people of large build; however, there are exceptions, so this parameter is still worth paying attention to when choosing a treadmill.
Note that it is worth choosing a model by weight with a significant margin — at least 10 kg more than your weight, even if you expect to lose it during training. If, on the contrary, you are going through a comprehensive training course in order to gain weight, then you should focus on the result you want by the end of the course. Anyway, the "weight category" of the simulator must be greater than the weight of the user — otherwise the device will work with off-design loads and may break at any time.
If the treadmill is planned to be used for several users, accordingly, you need to focus on the weight of the largest of them.
Max. running speed
The highest speed at which the treadmill can move. This parameter is indicated only for models of the electric type (see above) — in mechanical and magnetic ones, it depends solely on the capabilities of the athlete himself, and it is impossible to accurately indicate the maximum speed in the characteristics of such simulators.
The higher the maximum speed — the greater the load can be given to the trainee and the better the treadmill is suitable for intensive training. However, for household models, a speed of 15 – 16 km/h is considered quite sufficient; more "fast" simulators usually belong to the advanced class and are designed for professional athletes.
Note that in everyday use it does not always make sense to chase a high maximum speed. If your level of physical fitness is not high or if high loads are undesirable, a speed of 10 – 12 km/h may well be enough.
Motor power
Power of the motor installed in the electric treadmill (see "Type"). This indicator is directly related, first of all, to the smoothness of the ride and the maximum speed (see above) — the more powerful the engine, the more uniform the movement of the canvas will be and the faster it can move. Also, engine power determines the resistance to high loads: with an equal weight category (see "User weight"),
a more powerful model is better suited for people with large body weight, especially at high speeds.
In general, most recreational treadmills have motors between 1.5 and 2.5 hp; more powerful options usually belong to the professional class.
It is worth noting that above we were talking about the constant power of the engine — that is, the power with which it can work for a long time without being subjected to overloads. In some models of simulators, the so-called peak power — the power that the engine can develop for a short time, for a few seconds. It is higher, but long-term operation at such a load is fraught with the failure of the device. Therefore, before buying, it is worthwhile to clarify, if possible, what power is implied in the characteristics — nominal or peak; this is especially true for high power models.
Training programs
The number of
training programs provided for in the design of the simulator. This is not about load levels, but about automatic modes of operation, during which the track can change the speed of movement, signal the beginning and end of a lesson, etc. For details on the number of programs, see Built-in Programs.
Running belt size (LxW)
Under the dimensions of the canvas in the characteristics of treadmills, they usually mean the dimensions of the working area — that is, the platform within which the user's legs stay during training. There are a number of points that determine the optimal length and width of the canvas.
The long treadmill length ensures safety — less likely to seriously stumble and fall out of rhythm. On the other hand, a long canvas requires a more powerful motor, and the dimensions of the simulator increase accordingly. With all this in mind, it is believed that the optimal length for home use is 120 – 130 cm; longer tracks are designed for use in fitness centers and professional training.
Both safety and comfort when using the simulator also depend on the width of the canvas; This parameter is especially important for people of large build — on a narrow canvas, they can be “cramped”. On the other hand, as in the case of length, a large width means a large size of the simulator itself. In general, entry-level models have a canvas up to 40 cm, in more advanced tracks there are options for 45 cm, and for professional use this figure can reach 50 cm.
In fact, when choosing a treadmill according to the size of the canvas, it is best not only to take into account all of the above, but also to try out the option that interests you in fact before making a purchase. After all, a lot depends on personal characteristics and preferences, and it is possible that...a seemingly suitable simulator will be small — or vice versa, a more compact and inexpensive option is quite suitable.
Dimensions
The dimensions of the equipment in the assembled and ready to work state. It is important to note that in fact more space is needed for comfortable and proper operation of the simulator.
Weight
The total weight of the treadmill when assembled.
All such simulators are quite massive — models weighing up to 50 kg inclusive are considered
light. And when choosing, it is worth considering that both small and significant weight have their advantages. So, lightweight structures are more convenient when moving, while weighty ones are more stable, often have more extensive functionality, and are also better suited for people with large body weight.
