1, reasonable distribution of physical strength
The first lap of 400 meters should not be too fast. Candidates with high level will be faster in the first 400 meters, and will be controlled when the level is low. After running 600 meters, they should make the final sprint a little earlier.
2. Adjust the running speed
Generally speaking, you run two or three steps to exhale and two or three steps to inhale. With the acceleration of running speed and the appearance of fatigue, the frequency of breathing also increases. You can use the method of running one step to exhale and inhaling one step. Exhale should have a certain depth, accounting for about one-third of vital capacity, with the emphasis on exhalation. Only by fully exhaling carbon dioxide can we fully inhale oxygen. Breathing is usually carried out with the nose and the half-open mouth at the same time. When practicing long-distance running or running against the wind in winter, in order to avoid cold air and strong airflow directly irritating the throat, the tip of the tongue should be upturned and slightly licked on the palate.
3. Pay attention to the explosion point
Grab the road and run into the route. Don't grab the road, don't overtake your opponent in the corner, or you will go ahead on the outside of the runway and lose more distance. It is good for overtaking to enter the straight after running through the corner. After entering the corner, try to run along the inside. You can enter the sprint at the last 150 ~ 200 meters, and don't be pulled down by your opponent before starting. When sprinting, try to increase the swing arm movement, speed up the pace frequency and amplitude, cross the finish line at the fastest speed, and don't look back at others.
4. Practice hard and don't give up halfway.
If we want to achieve success, we must practice hard. If running is regarded as a pyramid, the top events once or twice a year are its pyramid, and the endurance foundation is the tower foundation. Kentucky is the most interesting place for runners who pursue health. But for most runners, the tower foundation is the starting point and end point of the whole plan. Without a good foundation, it is impossible to work with greater intensity and speed.
runway
800 meters, the start is on their own runway, and athletes can't leave their own runway until they pass the separation line that marks the swimming lane. In the first round of the group competition, which runway the athletes are arranged on is freely arranged by the computer. In the next few rounds, the choice of runway depends on the performance of athletes in the final round. The purpose of this rule is to make better athletes queue up on the middle runway. Good runways are Runways No.3, No.4, No.5 and No.6, which should be occupied by the top four athletes respectively. 1, 2, 7, 8, the road is occupied by the last 4 bits.
achievement
In track and field competitions, the ranking of all runners depends on the order in which their trunk (excluding head, neck, arms, legs, hands or feet) reaches the finish line and ends along the vertical plane, and the first runner ranks first. In any competition, if the athletes' scores are equal when they enter the next competition according to their scores, the referee of the terminal camera should consider the actual scores of the athletes concerned11000 seconds. If the result is still the same, the athletes concerned should enter the next competition. If the actual conditions do not allow, we should draw lots to decide who will enter the next game. In the final, the first place has the same score, and the referee has the right to decide whether to play again. If there is an unconditional rematch, tie for first place. As for other rankings, the results are the same and will be processed in parallel.
