Treadmill
A treadmill is a piece of sports equipment that you run on and that is used for physical activity.
Basically, a distinction must be made between two different types:
- electronically operated treadmills
- treadmills powered by your own muscles
An electronically operated treadmill is similar to a conveyor belt used to transport goods . However, treadmills are not used for passenger transport; instead, moving walks that can be used in a similar way have been developed for these purposes .
history
The origin of the treadmill goes back to the 19th century. Documents show that the first treadmills existed as early as 1875. However, these were not made for humans, but were used to drive water pumps and gear trains by being moved by pack animals . The first treadmills for people were not developed until the middle of the 20th century, although at that time they were not intended as sports equipment, but rather for the transport of materials and products. It was only in connection with a stress test carried out by doctors that the first treadmill was developed with a view to physical activity and health.
Electric
Electrically powered treadmills are usually powered by an electric motor. The maximum speed is usually less than 20 km / h. Depending on the model, the band can be set at different speeds and angles of inclination, or allows programmed training programs to be called up (e.g. cross-country running or driving game ). The latest trend is the simulation of races or tracks that can be completed virtually on the treadmill.
There is no risk of getting caught in the moving tape, as the distance between the tape and the housing is only a few millimeters. In an emergency there is also the option of stopping the tape using a magnetic switch that is attached to the runner's clothing. Another advantage of a treadmill is the monitoring function of body activities such as pulse and calorie consumption. Most treadmills are equipped with sensors and computers that do this job.
Mechanically
In addition, there are treadmills that do not have a motor and that move using muscle power. Some have a flywheel , the inertia of which smoothes the speed curve more. Mechanical treadmills are usually cheaper than electric treadmills, both in terms of purchase price and maintenance, because they do not consume any electricity.
Records
The world record for 7 days of running on the treadmill was raised in February 2015 by Rainer Predl (25) from 833 to 852.46 km. During this time he only slept 15 hours.
Anti-gravity treadmill
For a long time, aqua jogging was used to regenerate muscles or bone injuries in order to reduce the stress on the joints through the buoyancy . For a few years now, the anti- gravity treadmill has been used for this purpose . From the waist down, the runner is in an inflated, airtight tent, which is closed at the top by a belt that fits tightly to the body (similar to the splash guard on a kayak ). By changing the air pressure in the tent , the runner can be raised so that, on the one hand, normal running is possible and, on the other hand, the body weight on the legs can be continuously reduced up to 10%. This enables earlier regeneration training, which enables much faster regeneration after injuries.
Use for therapeutic purposes
Training with the treadmill is also suitable for therapeutic purposes. Several clinical studies on treadmill therapy with partial weight relief have already shown that patients can use it to improve their ability to walk. Treadmill training is also used to treat age-typical diseases such as arthrosis or osteoporosis. Training with the treadmill improves joint mobility and increases gait security while reducing pain at the same time.
