Comparison Nordic Track E5.0 vs Pro-Form Space Saver 700

The maximum weight of the user for which the simulator is designed, in other words, the maximum weight of the athlete, at which the orbit track is guaranteed to work out the amount of time stated in the characteristics without the risk of breakage. This parameter should be adhered to as accurately as possible, do not be mistaken about the fact that 3-5 kg in excess of the calculated weight will not affect the device. Yes, most likely, the simulator will be able to work for some time, but it will experience loads exceeding the calculated ones, and at best it will fail earlier than expected, and at worst it may break at the most unfortunate moment, which is fraught with injuries. In addition, this case is usually not covered by the manufacturer's warranty, and you will have to eliminate the consequences at your own expense.

The design of the system that creates resistance on the flywheel of the orbit track and the corresponding load during training. The following options are currently in use:

— Mechanical. The operation of this system is similar to the brakes of a car: special brake pads are pressed against the flywheel, and by changing the force of pressing, the resistance to movement also changes. The advantages of mechanical loading systems are simplicity and low cost, reliability, the ability to create high resistance for large loads, as well as battery life — they do not require power, and in the design of the orbit track you can get by with a battery for auxiliary electronics (see "Power"). On the other hand, the pads, due to friction against the flywheel, create a certain noise, which can lead to inconvenience; they also wear and tear over time. The mechanical system is used mainly in low-cost orbitrek models.

— Magnetic. In systems of this type, the resistance changes due to permanent magnets: by bringing them closer to the flywheel or moving away from it, you can change the resistance to movement. Similar to mechanical ones (see above), magnetic load systems do not require power; at the same time they provide smoother adjustment and practically do not create noise. At the same time, this variety is poorly suited for training professionals — it is not capable of creating a serious load (although it...is usually quite enough for domestic use).

— Electromagnetic. This type of system is considered the most advanced. The principle of their operation is similar to magnetic ones (see above), however, instead of permanent magnets, stationary electromagnets are used in this case. The load, on the other hand, changes due to a change in the strength of the current passing through the windings of the electromagnets: the stronger the current, the stronger the magnetic field and, accordingly, the higher the resistance to movement. Thanks to this, electromagnetic models are able to provide very solid load levels, while maintaining one of the main advantages of magnetic systems — complete noiselessness. The main disadvantage is the need for a powerful power supply, which is realized either by connecting to the network or by installing a built-in generator (see "Power"). Yes, these trainers are quite expensive.

— Own weight. The load system allows you to work exclusively with the load of your own weight. The simplest mechanism, which has a minimum of nodes, is quite reliable and budgetary.

The weight of the flywheel installed in the orbitrek is a massive wheel, the rotation of which ensures the movement of the pedals and creates a load on them. It is believed that the more weight, the better: a massive flywheel provides smooth movement with a minimum of jerks and creates uniform loads that mimic natural ones as much as possible. This is especially important for athletes with a large body weight — from 100 kg and above. At the same time, it should be taken into account that the cost of the entire orbitrek directly depends on the weight of the flywheel, and for home non-professional use it is not always justified to look for a simulator with a very heavy wheel.

The number of fixed load levels (platform resistance during movement) provided for in the design of the orbitrek. The more such levels provided in the design, the wider the possibilities for adjusting the load and the more accurately it can be adjusted to the requirements of a particular user. At the same time, the abundance of adjustments accordingly affects the price.

The maximum horizontal distance between the platforms of the orbit track, which determines, respectively, the length of the athlete's step when working on the simulator. It is believed that for people of average height, a step length of 400 – 500 mm is optimal, and many simulators are made with this calculation. At the same time, there are models with a variable stride length, which allows you to adjust it to the personal preferences of different users.

Anyway, the step length should be chosen depending on height, physique and personal preferences. Too small a step will lead to the fact that you have to mince, and the imitation of walking will turn into marking time, and too wide will lead to inconvenience and an unjustified increase in load without increasing efficiency. Ideally, it is advisable to test the simulator before buying — how comfortable you will be on it. This applies to both fixed and adjustable stride length.

The possibility of folding the orbitrek to reduce its dimensions during storage and transportation. This feature saves space — the machine can be unfolded to full size and collapsed after use — which is especially true for small apartments where there is little floor space. At the same time, folding structures are somewhat less reliable than clumsy ones. Therefore, it is worth looking specifically for such a simulator only if compactness is of decisive importance for you.

iFit is a technology that provides access to a vast library of training programs designed for each specific machine and for specific fitness goals, as well as picturesque videos that allow you to diversify your workouts. Usually, orbitrecks with support for this system are equipped with an LCD display, and when you start a workout, an HD video appears on the screen of the simulator with views of the terrain along which the jogging route will be laid. The video sequence is complemented by thematic audio compositions. However, the possibilities of the technology go further than conducting workouts to video clips. Advanced models, which are equipped with a large screen and a module for connecting to the Internet, allow you to use the potential of Google Maps. That is, the user can independently lay the route of a morning run through the streets of some famous city.

— Management on the handles. The control buttons for training modes are placed on the handles of the orbit track. With their help, you can change the load without stopping the lesson. However, the control options in each model may be different.

— Fan. The orbit track has its own fan. This feature is useful for cooling during intense workouts with copious “warm-up” and sweating, especially in warm weather.

— Bottle holder. The presence in the design of the orbit track of a special stand on which you can put a bottle or glass. Thus, you will always have a supply of water at hand, and to replenish its amount in the body you will not have to be distracted from working with the simulator.

— Colour display. The presence of a colour monitor in the design of the simulator. This feature does not affect the main features of the device, however, such displays are considered more convenient and pleasant to view than black and white. And some models may include various additional features designed to make classes more interesting — for example, the ability to play DVD movies or virtual workouts (see above).

— Bluetooth. The presence of a Bluetooth wireless module in the orbit track allows the simulator to be synchronized with the user's smartphone, tablet or laptop / PC. Thank...s to data synchronization, the user will be able to control the results of training in a convenient form. Additionally, Bluetooth wireless communication can be used to download new training programs to the on-board computer of the simulator and synchronize with the heart rate monitor via the ANT protocol.

— Wi-Fi. The presence of a Wi-Fi wireless communication module in the design of the simulator. The Wi-Fi interface was originally intended for connecting to computer networks (including Internet access), but more recently it has also been used for direct connection between different devices, without using a network. The specific features implemented using this module may be different. So, some simulators are able to interact with training programs installed on tablets and smartphones and transmit information to such programs about the details of the training (distance traveled, calories burned, etc.), others allow you to update the firmware or change the settings remotely, etc. .P.

— USB connector. USB itself is a universal interface designed to connect external peripherals to a computer or other control device. Actually, for the same purpose it is used in modern simulators; but the specific application in different models may be different. So, USB can be used to connect heart rate sensors and other specialized accessories, to play music and/or video from external media (for example, “flash drives”), to update the firmware using the same media, etc.

— TV tuner. The presence in the design of the simulator of a TV tuner — a device designed to receive television broadcasts. This function is useful for those who would like to be able to watch their favorite TV programs, series, etc. right in the process of training: usually, models with TV tuners also have colour displays and speakers (see below), which allows you to watch the broadcast directly on the simulator. However you need to remember that tuners can be designed for different broadcast standards; therefore, before purchasing a model with this function, it is advisable to make sure that it is compatible with local TV broadcasts.

— mini-Jack 3.5 mm (Aux). The 3.5 mm mini-Jack (Aux) connector is designed to connect an MP3 player or a smartphone/tablet. Thanks to this, it is possible to output a sound signal from multimedia devices to the speakers built into the orbitrek. Some models may additionally have a mini-Jack connector for connecting headphones. The sound output to the headphones will allow you to train to your favorite music without disturbing other users in the same room as you.

— Speakers. The presence in the design of the orbitrek of its own speakers. They can play music, the sound of a movie playing on the display (see "Colour display"), as well as various service messages — for example, a warning about exceeding the maximum heart rate.

— Tablet stand. Allows you to securely and safely mount a tablet with almost any screen size on the orbit track. Thanks to this, the user can enjoy watching TV shows or movies directly during training. Usually, the stand is located under the main screen of the simulator. Advanced class models are often equipped with a stand with the ability to adjust the angle of the tablet.

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.
