Four types of people are not suitable for running treadmill exercise:
1. People with arthritis, meniscus or ligament damage or artificial joint replacement will cause repeated wear and tear of hip, knee and ankle joints due to high-frequency running. People with joint problems will get more and more injured when they run ;
2. For patients with heart disease, because the speed of the treadmill is difficult to control and the load on the heart is relatively large, it is very dangerous in the event of an accident;
3. For people with cervical spondylosis and lumbar spondylosis, running in a state of high concentration for a long time will cause tension in the neck and lower back muscles, and the treadmill also has a recoil on the spine, which may aggravate the original condition;
4. People with osteoporosis are prone to sprains, falls and fractures during high-intensity running due to their reduced bone density and loose ligaments.
How to maintain a running treadmill:
1. As one of the large household appliances, treadmills have high requirements on motor power. Therefore, under the condition of unstable voltage, do not blindly use the treadmill. Weak voltage not only makes it difficult to drive the treadmill, but also reduces the feeling of use and exercise efficiency, and damages the motor.
2. Add lubricating oil in time. It is one of the most important maintenance methods to protect the inner hub and outer belt of the treadmill. The correct nursing steps are to clean the impurities between the running board and the running belt, remove the oil stains, and add the specified brand of lubricating oil to the inlet to prevent leakage.
3. The treadmill is usually turned off after 2 hours of use, allowing the motor to rest for 10 to 15 minutes.
