How kind of legs run fast

In the sprint competition, in addition to exerting the maximum physical limit, we should also pay attention to the method of efficient use of physical fitness. The definition of short-distance running technology is a reasonable and effective method or means to solve the problem of human beings running the whole distance at the fastest speed within a certain distance. Sprinting technique Running form:

It refers to the reasonable and effective movements used to achieve the maximum speed in the process from the starting point to the end point, although it is greatly affected by individual differences, it is necessary to understand the general principles of movement technology in order to obtain the correct mechanical posture. Pace: refers to the technique of effectively distributing the body's limited energy to achieve better results, how to avoid too much tension caused by excessive exertion, which affects the speed and range of movements, runners need to have the ability to relax during running, that is, they need to have a good pace.

Strategy: refers to how to create one's own effective combat methods under the principle of abiding by the rules. For example, in the preliminaries, semi-finals, and finals, use some appropriate methods to allocate the physical exertion of their own battles.

Sprint Movement Essentials Speed in sprint running is the foundation of every sport. The technique of running is the basis of other running and jumping events. The essentials of sprint running include:

1. Start, 2. Acceleration run, 3. Maintain the maximum speed, 4. Crossing the line. After hearing the gunshots, his hands quickly pushed off the ground; Bend the elbow to make a strong forward and backward swing arm, and the forward swing arm has the feeling of the elbow swinging forward and upward; At the same time, the legs push and straighten the starting board, the hip joint and knee joint can not be completely straightened, only the force of propulsion occurs, the front foot is quickly straightened, and the body is pushed forward in a large forward posture; The back foot is raised forward and the knee is strided, the knee joint is at an acute angle, and the inclination should be large to help the front leg generate horizontal propulsion. When the hind leg is stepped out, one of the arms swings forward.

One rear oscillation, keep the body from twisting left and right, and the body angle is about 45 degrees to the ground. The distance of the first step should not be too long, and the knee joint should not be raised to shorten the arc length from the starting board to the landing point. Stride length and step count are the two major elements of acceleration.

In the process of acceleration, the stride length is gradually increased with the increase of the number of steps, until the maximum speed is generated, in general, the maximum speed can be reached after 18 or 19 steps after the start, and the stride length changes little. There are four types of postures for crossing the line: jumping, raising arms and chest straight punches, raising arms straight punching, and swinging arm straight punching style. Among them, the swing arm straight flush type is the best.

Therefore, the runner will maintain the same position when he reaches the finish line, turning his body slightly to touch the line with the side of his chest. A slight twist shortens the contact distance, while the center of the chest remains the same. Also, try to land on 1/3 of the front part of the ball of your foot, it will be faster!

Legs with strength, explosive legs, legs with flexibility.
