Why is there no strength after 100 meters and 12 years old after 50 meters?

Why is there no strength after 100 meters and 50 meters, your body is in the growth stage now, so your strength is explosive.

Endurance is not enough, I personally recommend strength training twice a week.

There are many factors for the lack of energy in the last 50 meters, especially in the first 50 meters after running 100 meters, especially ventilation, or hold that breath. Otherwise, you'll just feel weak. The boys' 100 meters are usually changed in one breath or halfway. Girls usually do it 2 to 3 times.

It's also possible that you don't have enough stamina to run the 100 meters at full strength. There are a lot of tricks in running the 100 meters that don't have to be done at full strength, and having a buffer when you reach 70 percent will help you sprint to the finish line faster.

Run in the last 50 meters to increase the frequency of your arm swing.

And you also need to train your endurance more.

It is important to warm up before running, if you don't warm up enough, you can easily have problems such as leg cramps when running. To master the skills of the start, it is very important to have explosive power at the start, and you must concentrate on the start and not rush. When running, you should pay attention to the rhythm, and you must run according to the rhythm of your usual training, and you can't be fast or slow.

How to run 100 meters, 100 meters sprint skills.

1.Take a deep breath before the game and try not to breathe during the game.

2.The first 30 meters are centered forward, the mid-range is adjusted back, and the last 30 meters are ready to press the line.

3.When you swing your arms, your fingers are straight, and you think of it as a saw.

4.Use the toe at the start, and switch to the forefoot in the middle and beyond.

5.The swingarm should have strength and speed.

6.Be confident when running, and you should get yourself excited before you run, so that your brain can work faster, so that you can rush out as fast as you can when you start.

7.It's also a tip to put your center of gravity high when running, you have to imagine yourself as 1.9 meters tall with a straight waist.

8.Be sure to have your own rhythm when you run, and not be disturbed by external factors such as the rhythm of others.

9.Feet on the ground with the forefoot, push back hard, don't lift your leg too high after lifting, this will lengthen your time in the air, set up obstacles for you to create good results, but when you step forward, you must use all your strength to take your steps. Generally, sprinters will wear running shoes, and there will be some nails in the front of the running shoes, which are specially designed to let the athlete's forefoot touch the ground and run fast.

There is a distance in 100 meters, usually a 50-meter sprint does not consume endurance, and 100 meters is a test of some endurance.

After running 100 meters and 50 meters, you have no energy, because you are still young, only 12 years old, not yet mature, and your speed and endurance are much lower than that of adults.

This is related to personal physical fitness, if you don't exercise regularly, you won't be able to reasonably distribute your physical strength, you can't run 100 meters well, you have to exercise regularly, in order to have a good body and good results.

This has something to do with the individual's physique, and it is also related to the individual's usual exercise.

You can run 100 meters normally, so let's strengthen your workout! Don't stay active all day, sit and play extracurricular sports, and all kinds of ball games will do.

When I run 200 meters, why do I lose energy in the last 50 meters?

Hello dear I have found out for you when I run 200 meters, why am I bored after 50 meters? A: Because you reach your personal lactate threshold, lactate is produced in large quantities and starts to hinder your ability to exercise.

It also shows that your muscle glycogen reserves in your body are insufficient, energy is depleted, and you can't maintain 200 exercise intensity (which also shows that your muscular endurance is insufficient), your absolute strength is relatively insufficient, and the maximum strength is too small, which is also a reflection of your lack <>of 200 meters, I wish you a happy life

Don't look at 100 meters short, but there are also physical requirements, the back is boring, it is your physical fitness that can't keep up, when you have time, you still run more long distances, which is beneficial to you, run and change the speed of running, such as running 100 and walking 50.

Running 100 meters can only be achieved well with more practice.

It means that you are not explosive enough and can only run 50 meters. I'll send you the training plan for your reference.

Warm up and run three laps first, pulling the ligaments. Raise your leg 50 to 60 times in place, jump 50 meters in stride, twice. Run 30 meters with high leg lifts and sprint 50 meters, doing 3 to 5 sets.

Rest for 3 minutes, run 3 to 4 60 meters, run 2 to 3 100 meters with squatting, and use 70 percent of your strength to run 3 150 meters.

Sit-ups, at least 3 times a week. Do 5 to 6 sets of 20 to 25 at a time. Do push-ups at least 5 times a week. Do 5 to 6 sets of 20 to 30 at a time.

Jump rope 150 to 300 times at a time, or you can use time to jump in place for three minutes. Jumping 3 sets, jumping rope can increase your own bouncing power and increase the coordination of your body.

Frog jump at least 2 times a week, 3 sets of jumps each time, each group of 30 to 50 meters of high strength once a week to press the barbell to do squats, half squats.

With your mind, let yourself stick to it.

Summary. I used to run tens of thousands of meters because the physical conditions at that time were very good. The bottom of my heart is full of youthful vitality. It has more potential for muscles. It is difficult to jog for 100 meters first, but it is only the reason for the decline in physical function.
