When people run on the treadmill, if the treadmill doesn't often change its angle and keep a speed, all the forces will concentrate on one point of the knee joint. Older and overweight people's articular cartilage, meniscus and surrounding ligaments have been tortured to death by years and weight. Together with an impact on the treadmill, it only takes 3-4 months to destroy the knee joint.

Disadvantages of treadmills:

Broken leg and dislocation

Treadmill is a device specially designed for brisk walking, jogging or running. Some common knee, hip injuries and leg fractures are caused by runners jumping forcibly on the treadmill. The running belt movement of the treadmill imitates the road surface. If you join other sports during running, you can imagine that you will be easily injured.

Tibial pain and stress fracture

Excessive exercise in any environment may lead to tibial pain and stress fracture. Many runners mistake the stress fracture of the leg for the pain of the tibia, thinking that it is good to survive. But in fact, the two are not the same, and both need appropriate treatment.

Excessive exercise may cause pain in the tibia, that is, every time I put on running shoes, my calf hurts faintly. If the pain disappears over time, you can wear shoes unimpeded, indicating that your calf pain has healed itself. But if you still feel pain when walking on hard ground, you may have a stress fracture. If the pain persists, seek medical attention immediately, otherwise the situation will be worse.

Half-hearted harm

Running on the treadmill allows you to carry your mobile phone or other electronic equipment with you. This may lead to inattention and injury. Most people jog for a while after getting on the plane, and then run faster. In the acceleration stage, texting, making phone calls and even using electronic products may cause serious sports injuries.

Extended data:

Warm up and flow well before going on the treadmill, otherwise it is very easy to cause thigh and calf muscle strain. Leg press, squat, stretching muscles, flexion and extension joints can reduce the temperature of muscles and make them softer. After getting on the treadmill, you should start with "dynamic" warm-up such as walking and jogging, and gradually increase the amount of exercise. This process usually takes 10 to 15 minutes. In addition, when you get off the treadmill, you should gradually slow down to prevent dizziness and fall.

Precautions for running:

1. Don't lower your head, raise your head, and keep your eyes on the front, so as not to hurt the cervical vertebra.

2. When running uphill, it will be easier to reduce the pace.

3. The landing feet should be light, and the overweight "waste" will increase the burden on the bones; When your feet touch the ground, your knees should bend slightly.

4. The back should be kept straight and relaxed. Lean forward because of poor stability and strength. At this time, try to straighten out and exercise your muscles.

Don't twist your hips and waist too much, which will increase the chance of injury.
