However, if the running posture is incorrect, it will not only fail to achieve the ideal fitness effect, but may also bring harm to the body. \x0d\ Error 1: All feet touch the ground. Many people are used to touching the ground with all their feet when running. In fact, this landing method is not correct. Because there is no buffer and transition when landing, it is easy to "squat" and easily impact the cervical spine, especially when running on hard ground such as asphalt road. In the long run, it is easy to cause tibial periostitis. \x0d\ Error 2: The stride is too big. When people start running for fitness, they always like to increase their stride to improve the exercise effect. In fact, increasing the stride will inevitably lead to long flight time, large fluctuation of the center of gravity, heavy landing force and increased vibration to the human body. When you exercise on the treadmill, you should choose the appropriate speed according to your own ability. Stride and stride frequency beyond one's ability may increase the chance of sports risk. \x0d\ Error 3: Internal and external characters. Many people have splayed feet when walking every day. If they still have splayed feet or splayed feet when running, their knees and toes can't keep the same direction, which will increase the burden on the knee joint and easily cause injuries to the knee joint and other parts in the long run. \x0d\ Mistake 4: Look up and watch TV. In order to get rid of athletes' boredom, many gyms have installed televisions above treadmills or machines, so many people either raise their heads or lower their heads when running, which will increase the burden and vibration of cervical vertebrae. When running, naturally keep your head straight and your eyes straight ahead. \x0d\ Error 5: Swing from side to side. Some enthusiasts, especially teenagers, like to shake their bodies from side to side when running. They think running like this is "exciting", just like the "swinging" action of riding a bicycle. In fact, this will not only increase unnecessary physical exertion, but also destroy the linearity of running and affect the speed and effect. \x0d\ So, what should the correct posture be? In fact, the essence of running is to exercise at a relaxed speed. When running, your upper body should lean forward slightly. This "leaning forward posture" invented by Russian athlete Nicholas Romanov can not only reduce the joint burden and exercise intensity, but also prolong the exercise time. The range of leaning forward should be natural and comfortable. If you lean forward too much, it will increase the burden on your back muscles; If you lean back, it will lead to excessive tension in the chest and abdomen muscles.
