However, due to the different physical qualities between people, the actual time spent is also different.

Training methods:
1, variable speed running training
The so-called variable speed running is the training of running the same or different distances at different speeds. Almost all the training methods of 400-meter running are variable-speed running, and many excellent athletes in the world still use variable-speed running training methods.
So this is one of the most basic methods of 400-meter running training. The main feature of this kind of training is that the energy metabolism of the athletes in training is close to 400 meters, but the running speed is much lower than the competition. The intensity standard of variable-speed running is equivalent to 60%-70% of full-intensity running, and the pulse beats per minute are 140- 160.
2. Training method of interval running
It is a method of practicing in strict accordance with the prescribed distance, frequency, interval and rest mode. The most fundamental feature is that athletes are required to carry out the next training without full recovery, focusing on the development of anaerobic endurance. This interval training method is one of the most important training methods in the 400-meter event.
So, what is the scientific basis of interval training method? How to arrange the running distance, exercise intensity, rest time and rest mode to achieve the best effect? Here is a brief introduction.
It can be said that Tobeck's interval training is more formal and successful. Running distances are mainly 200 meters and 400 meters, and the amount of training is gradually increasing every year.
The factors that constitute the training method of interval running. There are five factors: location, running distance, running speed, rest mode and repetition times. Therefore, everyone can make various training plans for variable speed running based on this factor according to their own situation.
(1) venue: mainly on the runway.
(2) Running distance: Most people run for 200-600 meters. However, in order to strengthen the training of respiratory and circulatory system and adapt to the complex situation in the competition, some people not only repeatedly carry out interval training for short-distance sprints (50- 100 meters), but even carry out interval training for longer distances (600- 1000 meters).
(3) Running speed: Interval running training has the best effect at heart rate120-180 times/min.
(4) Rest arrangement: During the interval training, the next group of exercises can be conducted at the interval of120s-180s.
(5) Repetition times: Repetition times are determined according to the relationship between athletes and other factors (running distance, running speed and rest mode). In general, it is usually carried out between 10 and 20 times.
3. Training methods of interval running for different purposes
(1) Interval running develops endurance. This kind of interval running needs a little speed control, which is not strong, short jogging time in recovery period, many repetitions and long distance.
(2) Develop speed, enhance leg strength and run intermittently. High-intensity short-distance fast interval running (50m) and short-distance full-intensity running (100-200m) are adopted, with a long interval, which can be carried out not only on the runway, but also on the sloping runway.
(3) Run intermittently to improve practical ability. Usually used before the game, and timed at the same time. It should be emphasized that you should run as hard as possible in the second half, jog with high quality when you recover, and have fewer repetitions.
(4) Experience the interval running in different positions and the interval running by more than two people. To experience and adapt to various positions repeatedly in the competition, we can negotiate or alternately lead or consciously create encirclement. Of course, we can also take ourselves as the main body and experience disadvantages, disgusting positions, backward positions, internal roads and external roads without consultation.
(5) Improve intermittent operation technology. Intermittent running can not only enhance the endurance of respiratory and circulatory system, but also cultivate correct running posture. For example, it emphasizes intermittent running with swinging arms, increasing stride length with high leg lifts, and relaxing and striding intermittently.
(6) Speed Distribution of Intermittent Running In intermittent running, you can use running with sharp changes in up-and-down speed, and you should also carry out intermittent running in a planned way according to the speed changes required by the actual competition.
