In fact, many people in the ordinary running process, are using the wrong running posture, so that the effect of exercise will be discounted, while in the process of exercise is particularly vulnerable to injury. The controversy over running posture is a long-standing topic among runners. Runners who support forehand landing believe that forehand running can increase speed and reduce the risk of knee injury; runners who support full-palm/heel landing first believe that this can effectively utilize the joggling technique of running shoes and relax muscles and joints while running; and some "middle-class" think that running posture is due to people. Different, as long as they are used to it. Recently, Dr. Nicholas Romanov, an expert of the American Triathlon Coaching Committee, introduced a "Pose Method Running" in his new book "Running, How to Run". His theory is based on his track and field coaching experience of more than 20 years. He believes that there is a universal optimal running position for all people. His theory is not simply to answer the question of which part landed first, but to give a standard of running posture. Many of his followers, after training according to his method, have effectively improved running efficiency and reduced the frequency of injuries. Specifically, "Posture Running" has the following points: 1. Keep the muscles of the whole body relaxed. 2. The body leans forward slightly and the supporting foot is directly below the body when landing. 3. Pull the supporting foot off the ground with the strength of the posterior thigh muscles. 4. Keep the legs bent all the time, support the foot in the middle of the palm to form a support point, the body is S-shaped. 5. Small strides and high frequencies. Don't stretch forward excessively when the supporting foot is pulled off the ground. So many rules can make you feel that such running posture is too deliberate. In fact, when you take off your running shoes and run barefoot, you will find that your running posture is very close to the description above. Therefore, the author calls this running method "inaction" when training team members, which means that this running style is the most natural and most in line with the characteristics of the human body. But this does not mean that we can easily master this running position, especially for runners who have been running for many years and have formed a fixed position. Before the author learned to practice this running posture, he tried many running postures in order to avoid injuries, but the result was that it was impossible to do so, instead, more parts were injured. Specifically, the advantage of this running position is that compared with the forehand running, the "posture running" has no toe pedal, so that you will not feel excessive pressure on your ankles and calves. Many opponents of forehand running argue that the calf muscle strength of runners is not enough to support the body to run longer distances, while "posture running" requires that the landing position of the supporting foot be closer to the arch of the foot, and that the heel should also be landed, but it basically does not bear the weight of the body. When overcoming gravity to lift the supporting foot, only the rear thigh muscles and buttocks muscles exert force, feeling is to pull the foot off the ground, rather than the foot itself to give a downward pressure on the ground, and then rely on reaction force to lift the foot. This action also reduces the contact time between the foot and the ground, thus improving the efficiency of running.
