How do junior high school students run 400m and1500m?

The main focus of physical strength distribution in the1.400m race is on the final speed of100m. Physical strength distribution, according to the environment of your school, accelerate from 0 to 100 meters, keep the speed from 100 meters to 300 meters, and sprint from 300 meters to 400 meters. Generally between 290 meters and 320 meters, amateur trainers will accumulate quite a lot of acid in their legs. The purpose of this physical distribution is how to prolong the time of this phenomenon. In fact, the distribution of physical strength varies from person to person, and there will be no standard. According to my observation, the physical strength of 400-meter running should be distributed like this. Before 100 meters, after accelerating to the highest speed, adopt the method of inertia running. This inertial operation must maintain a relatively high speed. Secondly, we must absolutely relax. In the first 30 meters before entering the second corner, it is necessary to accelerate the use of inertial running+relatively complete corner running technology after entering the corner = saving physical fitness. At the moment of bending down, all the accumulated physical strength should be released. 400 meters is a sprint. The standard posture is: the upper body is upright and the body leans forward slightly. Swing your arms back and forth 45 degrees, relax your hands (virtual fist), send your hips forward obviously, raise your thighs (parallel to the ground as much as possible), relax your calves, and touch the ground with your forefoot. When touching the ground, there is an obvious backward "scraping" action.

2. 1500m is a middle race, which is also a relatively difficult event. To tell the truth, there is no quick and easy way. The first thing is to know about yourself and your opponent. Whoever has a high level and good grades should know fairly well. Second, we should be fully prepared. Prepare a comfortable sportswear, and remember that you can't wear new sports shoes, which are easy to rub your feet. Have a good rest the day before the game. Don't eat too much before the game and don't drink water for half an hour before the game. Don't start too fast, stay in the middle and don't fall behind. If you fall behind too much, it will be difficult to catch up. There are two tactics to choose from in the competition: one is to follow, find an athlete with good grades, follow him all the time, and then overtake him in the final sprint. The other is to run ahead. Those with good physical strength can run ahead, and it is not easy for them to catch up if they leave others behind. You may not always win the first place in the competition, but you should do your best without regrets. In the race, you must run at an average speed. Running like this is also the most labor-saving. Start faster, sprint with all your strength, and keep the average speed at other times. After the race started, some people ran very fast at the start. Such people can't get good grades in the exam, so don't follow. It is also very important that after running a third of the distance, you will feel uncomfortable, have difficulty breathing and don't want to run any more. This is a physiological phenomenon. Excellent athletes known as "poles" will also appear, but they appear late and not obvious. Be sure to stick to it at this time, and it will be fine in a moment. That's all. I wish you a satisfactory result.

It is best to wear vest shorts and running shoes when running, and you can wear T-shirts, tights and running shoes. If you don't have running shoes, wear a pair of light high-heeled sneakers (don't wear those thick-soled sneakers). Pre-competition warm-up activities include jogging, ligament stretching (leg press, waist stretching, upper limb pressing), dynamic exercises (sprinting about 30 meters, leg-lifting running, back pedaling running, etc. You should exercise fully, especially the ligaments should be pulled apart, otherwise the weather will be cold, your muscles will be stiff and you won't run well.
