A certain question about running. HELP！！！！！！

The usual reason is because long-distance running is a running that can control the rhythm, you don't need to sprint too fast in the early stage, and you can even speed up when you run halfway, which is also normal, and 400 or 800, especially 400, that is the most tiring, because you have to sprint all the way, so you need to keep your body in the fastest state from the start to the end! The 800 is similar. As for the sprint speed, it is unlikely to increase the short-term speed, only at the start of the lead, and at the end of the line to master a certain amount of skill.

There are also sprints that generally practice squats, and if you can, you can increase the weight of the barbell appropriately, but you must pay attention to the problem of how much to add, otherwise it is the most troublesome thing to get injured. Thank you, this is some of my previous exams and exercises, I hope it can help you, I wish you success in the exam!

Sprinting is anaerobic metabolism, and long-distance running is aerobic metabolism.

Targeted contact is recommended.

You can run in the sand, and you can increase the speed of your sprint! You can try.

You can change the field to run, each field, the oxygen content is different, often contact the high leg lift, as well as short sprints, improve explosiveness, you can try to run a 5 km every day, you can enhance physical strength.

Maybe it's too tiring to work out for a long time, right? Improving the speed of sprinting requires training on reaction speed and explosiveness. See your doctor.

That's why the 100-meter flyer is so much of the world's attention, whether it's running or hurdles.

There is a certain amount of skill, and other attachments may have a certain effect, but the method is key.

It is recommended that you consult your PE teacher, after all, he is closest to you, can best experience your physical fitness, and will have unexpected gains from communicating with him.

Good luck

omg……To be honest, I have also run 4000 meters, and I have never seen a ...... with a tracheal running injury

It may be that you are not born with this piece ......

I don't know what kind of injury you are talking about, have you been to the hospital? Or is it just hard to feel it?

It may be that the environment in which you run is too poor and the air pollution is serious.

Let's go on a day with better visibility.

LZ itself has internal injuries! 1 Huh.

Don't be nervous,,, tie sandbags,,, don't get too tired, just work hard.

Do five sets of high leg raises.

Three sets of sit-ups.

I'm sure you'll be able to run fast, I'm on the track team. Trust me!

One set at a time.

It depends on your own strength. If you are very strong, you can play your level after fully warming up.

Fast is a neurological problem, and you have to force yourself to train, such as running downhill. Wait.

Take a deep breath before the game, and the turn is a big swing of the outer arm.

Train hard and wear spiked shoes when you compete.

Improving physical fitness is not a day or two, keep exercising, you will be the first.

As long as you run as if you were the only one, then you will be a brother.

There are 8 pieces in total, the first 5 pieces, the second 2 pieces, and the last 1 piece.

The incubation period of rabies can reach up to 30 years, so it doesn't mean that it's okay if you don't get sick now, maybe you may not remember what it is like if you suddenly get sick after ten years, and rabies can only be prevented by vaccination at this stage, once the disease occurs, there is no way to treat it, so it's best not to take chances, it's not expensive to buy a peace of mind for hundreds of dollars, but it's more troublesome to get this injection into several shots, and there are quite a lot of abstinences, such as not drinking alcohol and so on.

Anti-rabies immunization is one of the earliest immunization methods, invented by the famous French scientist Pasteur. In 1885, the rabies vaccine was administered to humans for the first time. At present, the rabies vaccine widely used in China is made by using mouse kidney tissue culture and inactivation.

Anti-rabies serum is made from the serum of horses that have had rabies and developed antibodies to rabies after proper treatment.

When a person is bitten, scratched or licked by a dog or other animal, whether or not they are a rabid dog or a mad animal, they should be vaccinated against rabies.

If the dog or animal that bites a person must be a mad dog or a mad animal, or if the bite is severe, or if the wound is close to the central nervous system, such as the head, face, and neck, anti-rabies serum should be used in addition to rabies vaccine immediately. This is because it takes 15 to 20 days to produce antibodies after the rabies vaccine is injected, and the antibody level can reach the peak in about 1 month to effectively prevent the onset of the disease. When the bite is severe or the bite site is close to the central nervous system, the disease often occurs before the body has time to produce enough antibodies after vaccination.

Combined with the use of anti-rabies serum, the antitoxin of the serum can neutralize the free virus in the body in time, prevent the spread of the virus, and relatively prolong the incubation period of rabies, so that the body has enough time to produce its own antibodies, reducing the chance of onset. Allergy testing should be done with anti-rabies serum.

The rabies vaccine should be given 1 injection intramuscularly on the first day, for a total of 5 injections. 0 refers to the day of the first injection, and so on. If anti-rabies serum is injected, it is best to use it the day before or on the day of the vaccine, and should be given a booster dose on the 10th day and 10th day after the full 5 doses of the vaccine.

Rabies vaccine and serum should be injected in a timely, full-course and sufficient amount, and the earlier the injection time is from the bite time, the better the prevention effect.

You're too careless. I don't know how many days it has? It is important to know that the incubation period of rabies is 70% within one month, as short as 7---8 days, and as long as decades.

Therefore, it is difficult to accurately calculate the incubation period, whether it will develop the disease, and when it will occur. It is recommended that you follow the precautionary principle of 'it is better to make up for it than to be lacking', and go for the rabies vaccine as soon as possible.
