400 meters, when running, pay attention to the coordination of breathing and foot rhythm. Basically, the coordination of breathing and exhaling is 6-8 steps. Take as big a step as possible at this frequency. The whole process is like riding a bicycle. There is an acceleration process. Divide 400 meters into 4 stages: 1. There is a curve as soon as you start running. During this period, it is a uniform acceleration process, and the speed starts from zero. Increase it to 85 to 95 percent of your full speed. 2. It is a straight road after exiting the bend. During this 100 meters, try to maintain the speed you had when you exited the first bend. During this process, you must pay attention to your rhythm. If you finish the 100 meters at a constant speed. 3. At the second corner, your physical strength has dropped significantly. You need to reduce the speed a little without affecting the rhythm. Hold on! 4. In the last 100 meters, your physical strength has almost been exhausted. At this time, you must pump your arms. Swing as wide as possible, the swing of your arms will drive your legs to run together, take as long a stride as possible, and insist on maintaining the rhythm of your breathing. (I have practiced the 400-meter special event, and my results are just fine.

(I have practiced 400-meter special events, and my results are just about average. This is my experience. I don’t know if it will be helpful to you. On the contrary,I think the combination of breathing and pace is very important. The speed does not have to be very fast, as long as the speed does not get obviously faster during the whole process, just slow down!)
