Is a treadmill harmful to the body?

Running is a kind of fitness exercise we do in our daily life. It is also an aerobic exercise that is good for the body. It plays a role in strengthening the physical fitness and preventing various diseases. With the progress of society and the improvement of people's physical level, the ways of running have become more diversified. In particular, many friends will run on a treadmill indoors, which has many benefits to the human body. However, we must also pay attention to the method. Incorrect method can also be harmful. Let's learn about it below.

Excessive exercise. The time and intensity of exercise on a treadmill should be determined according to the purpose of exercise. Jogging for more than half an hour will consume fat, and jogging for more than an hour will consume protein. Therefore, if the purpose is to lose weight, the exercise time should not be too short or too long, 40 minutes is appropriate, otherwise it is easy to overdraw your physical strength and cause sports injuries.

The speed setting is too fast. The first thing to do when using a treadmill is to understand your own exercise limits. If you don't have enough physical strength and the set speed is too fast, it's easy to fall down because you can't keep up with the rhythm. This is a common problem for "newbies".

No warm-up. You should do warm-up exercises before getting on the treadmill, otherwise it is easy to cause thigh and calf muscle strain. Pressing the legs, squatting, stretching the muscles, flexing and extending the joints, etc. can increase the temperature of the muscles and make them softer. After getting on the treadmill, you should start with "dynamic" warm-up such as slow walking or jogging, and gradually increase the amount of exercise. This process usually takes 10-15 minutes. In addition, you should gradually slow down when getting off the treadmill to avoid dizziness and falling.

Through the above introduction, we now know that although treadmills are good, they can also be harmful to our bodies if used incorrectly. This is something we need to pay attention to when exercising on a treadmill. In addition, we must also pay attention to replenishing the body's water while running. Sweating while running can cause a loss of water in the body.
