Ask for running skills, 1000 meters, 100 meters, 400 meters, 800 meters, 400 meters, and comprehensi

Then you run slower first, and then run slowly faster, and you must practice more.

1. Straight acceleration of sprint run: Acceleration on the last straight of 400 meters can imitate the acceleration run after the start of 100 meters. When accelerating, bend your elbows and swing back and forth vigorously, and alternate your legs with hard pushes and swings forward.

It is no longer possible to accelerate as fast and powerful as a 100-meter run. In a state of extreme physical fatigue, you should move your weight forward and swing your arms as much as you can.

2. Control the rhythm of breathing and running: In the final acceleration stage of 400 meters, due to the change of working conditions of internal organs, the first level of oxygen seriously lags behind the needs of muscle activity. As a result, athletes will experience severe physical discomfort when they reach this stage.

For example, the breathing rhythm is disrupted, chest tightness, running speed is reduced, and there are thoughts of giving up. This phenomenon is a normal physical reflection. If the breathing rhythm is severely disrupted during the second acceleration phase of the sprint, the first thing to do is to maintain your speed and movement, and establish the belief that you will persevere to the end.

The second is to increase the intensity and depth of exhalation, try to exhale the carbon dioxide in your lungs, so as to inhale a large amount of oxygen to maintain the body's oxygen**, and minimize the negative impact of insufficient oxygen on performance. Remember, don't take a quick sip of air during the 400-meter sprint.

3. Finish line crossing technology: Crossing line technology is a very important application technology in sprinting, long-distance running and middle and long-distance running. Good line-crossing technique can often make the difference between victory and defeat in a stalemate of a match.

1. Lean forward slightly when running, and the angle with the ground is about 80° to 85°.

2. During the process of running, you should pay attention to raising your head and stomach, and cooperate with your feet to reduce the shaking of your body from side to side and reduce unnecessary energy waste.

In order to balance this forward leaning, it is natural to strengthen the coordination of the pedal swing and increase the swing amplitude of the upper limbs, so as to promote the technical action of the rear range without deformation, and finally achieve the effect of improving the rear course.

4. Let the heel land first, but pay attention to the foot surface can not form a large angle (less than 10 °) with the ground or the whole foot landing. After landing on the ground, move the center of gravity downward while moving forward.

5. When you start running (the first 500 meters), the breathing section is a breath every 3 steps, 3 steps and a breath, if you feel difficult to breathe when maintaining speed, you need to adjust it to 2 steps and one breath, 2 steps and one breath, and you need to keep the breathing uniform and depth consistent.

6. Others: Maintain good sleep and physical strength, prepare for exercise, and warm up and exercise the shoulder joints, elbow joints, back and waist muscles, legs, knees, ankles and other parts, so as to prevent injuries and improve sports performance.
