Second, jogging is not as slow as possible. Make sure that when flying, the calf is thrown forward, close to the thigh, and then the calf rebounds. When approaching the ground, the calf is almost perpendicular to the ground, and the calf has a certain angle with the thigh. The landing point is in front, the knees are behind, and the body center of gravity is behind the knees. (of a ground mapping point) then the body moves forward with the center of gravity passing through the knee. This is the foot has landed. The face cushioned the impact on the knee.
3. At this time, the heel is pressed to the ground, and when its bearing capacity is about to increase, the back pedaling action of the leg step begins to leave the ground again, providing enough power for the next forward flight. During the whole process, there was a feeling that the head seemed to be pulled off the ground by a rope. When you run, others look light. Keep running when you are tired, because your legs can't be thrown away and your knees can't be fully stretched. Every step you take is like using a hammer.
Fourth, lean back when starting. Although you are speeding up your running, your body will stand upright. Now you should lean forward slightly, but not too much. There must be a principle that you can't cross your knees before landing. As for the position of the foot tribe, it is best to follow the ground when it is slow (at this time, the body also leans backwards), and it is best to fall on the outer edge of the foot surface when it is medium speed. In this running posture, you must keep your waist straight and don't bow your head.
In fact, running exercise should be not only running, but also functional exercise, such as muscle training of ankle joint. Knee joint, hip joint and ankle joint should be hard and well coordinated, so as to share the load of the knee and the knee will not be injured.
6. Jogging is conditional. For example, you must have a pair of shoes with good shock absorption (good insoles will do), your body is too heavy (lose weight quickly first), and whether middle-aged and elderly people have degenerative factors such as osteoporosis and calcium deficiency (nutrition should keep up). None of these external conditions are available, and even the best running method is useless.
Seven, joint movement, stretching-contraction-stretching-contraction, so as not to get hurt, we can only exercise muscles, not joint bones, do more static exercises and stretch muscles, which has many benefits. This is all my experience.
