Long term participation in sprint and high jump competitions. Will it have any effects on the body?

Engaging in sports, or strenuous exercise. There's a chance that the membrane (as you call it) will rupture. If it breaks, it is also an accident.

It's not your fault. Don't worry too much, if you feel uncomfortable, you can go to the hospital for repair. Have a good day.

Will long-term sprint training cause any harm to the body?

There are many benefits of running every day, mainly to promote cardiorespiratory endurance and can reduce the occurrence of metabolic chronic diseases, such as hypertension, diabetes, hyperlipidemia, coronary heart disease, stroke, etc. Even running can prevent the occurrence of malignant tumors, these are the benefits of running. Any exercise is risky, including running can also cause injury, especially if you often run without paying attention to protection, or the running posture is not right, or the lower limb force line is abnormal, resulting in knee injury, so there will be running knee, knee pain, front tibia pain, heel pain, plantar fasciitis and so on.

This is not caused by running.

It is caused by physical abnormalities such as flat feet, thumb valgus or anterior pelvic tilt, foot varus and valgus, knee varus and valgus. There are many benefits to running for long periods of time. It will make the various muscle tissues of the human body consume more excess fat in the body, exercise the cardiopulmonary function, increase the lung capacity, and then make the digestive function and the physiological functions of the nine major systems in a better state.

It speeds up metabolism, promotes bone growth, increases bone density, improves sleep, and many other benefits.

But there are also some disadvantages, the bad part is mainly the wear and tear of the knee joint, because the human body is squatting, the pressure on the knee joint is very large, and the single leg is supported when running, so the weight of the whole body will be concentrated on one individual leg, and then cross back and forth, so that there will be friction on the meniscus of the knee joint, and this friction will not show anything for a day or two. But if it is a long-term run for 1-2 years, the friction of the meniscus is irreversible. Because there are no corresponding blood vessels and nerves in the articular cartilage and meniscus, pain is not felt.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

If the patient does not know how to protect the knee joint, long-term running will lead to excessive wear and tear of the knee joint, pain, if the patient runs for a long time, he must pay attention to protecting the knee joint, you can wear a knee brace, or take a proper rest during the running process to relieve the fatigue of the knee joint.

It can be improved a little, but the important thing is to master the skills.

If you can read it, just look at the following paragraphs. If you can't stand it, just read the title.

1. Stand with both feet equally.

The two-legged stance is often overlooked. Physical education textbooks have different opinions on this issue: some "slightly divide the legs"; Some require "shoulder-width width feet".

As for what posture to stand into, the textbook does not specify specifically, so most physical education teachers use the "eight" shape standing method. In my teaching practice, I feel that the former scale is difficult to grasp, while the latter is clear but larger. Here's how I do it:

Stand with your feet in an upright position, then use your foretoes as a support point, and follow your feet apart to the sides until your legs are parallel. In this way, the toes are forward, consistent with the direction of movement, and the legs are basically in a vertical position, which does not produce an angle, and is conducive to the movement of the knee and ankle joints. And students dare to grasp it easily.

2. The swing of the arms and the coordination of breathing.

It is important to swing the arm and breathe properly. In the teaching, the arms are relaxed and slowly swung from the bottom to the top to the head, followed by a relaxed inhale, and then the arms are exhaled from the top to the sides and back. When it is time to jump, the arms are quickly swung from the bottom to the top of the head, and now the breath is quickly and deeply inhaled and the hem is carried to the sides and back, the movement is as fast, but not exhale, but hold.

This provides maximum energy for the muscles before they take off, and enhances the instantaneous explosive power of the muscles when they take off.

3. Shift the center of gravity of the body forward.

In teaching, my practice is as follows: before jumping, when the arms swing from top to bottom to the sides and back, the upper body leans forward, and then the arms are bent into a semi-squat position, the heels are lifted, and the forefoot is used to grasp the ground, control the body balance, and the center of gravity moves forward. Although the center of gravity is not very forward, it is important.

In this way, there is no need to expend force to move the center of gravity forward when taking off, and the conditions are created for the body to move forward and upward.

Fourth, pedaling is the key.

The effect of the swing during the take-off is an important factor in determining the distance of the body. In teaching, I don't simply swing the Tongbuji from back to front and upwards as in the textbook. Because that pendulum only acts on the arms, but not on the whole body.

For this reason, I use the swing of my arms when I jump high, but not just upwards, but forward and upward. When jumping, kick the ground with the forefeet and swing your arms from the back of the sides to the front and upwards to lift your body forward and up.

There will be an impact. Sprinting or long-distance running for a long time.

Muscle fibers are different.

However, in this case, it is recommended that you train for endurance.

You can jump up the stairs every day. Work your thigh muscles. Or do a squat with a heavy load on your shoulder. Exercise your leg muscles and do some squats on a regular basis. Squat jumps. Work on the coordination of the bounce. Until the legs are weak. If you can't do a few, you won't do it.

It can be in groups of thirty. Do three sets a day. After a long time, it was changed to five groups. It was easy to do this slowly. It is necessary to strengthen the connection between the lumbar and abdominal muscles.

Lumbar abs exercises are designed to help you walk farther away when you are standing and jumping.

Only the lumbar abdominal muscles are good. Only then can there be air supremacy.

When jumping. Be sure to exert force from your thighs. Homeopathy to take the body out. Movements should be practiced. The body cannot be disconnected.

If there is a condition.

It is mainly the coordination of lower limb strength and movements, the angle of vacancy, the expansion of the hips and abdomen in the air and the swing of the arms.

Enhance the ability to bounce and coordinate the exertion of the upper and lower limbs.

There are also explosive exercises for the lower limbs.

Follow the correct way to jump the long jump and swing the arms back and forth. On the line, there is a qualification problem for the long jump.

Acceleration run, step point, jump angle.

Practice frog jumping, kick jumping, running stairs, practice posture, and try to be driven by inertia before going down to the pool, so that your feet are forward.

Do more strength training, do frog jumps often, and try to lift your body up when you take off.

Exercise more leg muscles and waist muscles. You'll find that you've grown a lot.

Jump boxes and steps to practice the explosive strength of your lumbar abs and lower limbs!

Practice tomorrow and walk with larger steps

Practice more lightness, leg muscles are not developed.

Long jump. It is important to pay attention to the warm-up exercise before taking off, otherwise it is easy to get injured and muscle stiffness.

Technical points of standing long jump:

1.Stand with your feet shoulder-width apart;

2.Squats should be deep (thighs should be parallel to the ground);

3.When stepping and jumping, the arms should swing upwards with all their strength to drive the body into the air;

4.When vacating the air, the head should be tilted upward;

5.After Teng Jianchang is empty, he should do his best to close his abdomen (Da's finger legs are close to his chest), and his calves should be stretched forward as much as possible (don't be afraid to sit on the ground);

6.Don't be afraid of the weight when you land quickly, pay attention to the fact that after the foot lands, the buttocks will naturally move closer to the calf. (Many children stand on the spot when they land, and their grades will be much worse.)

Human bouncing power is limited.

And to jump far, you need not only a vertical speed, but also a horizontal speed.

If you have a stationary long jump, you have to jump not only upwards but also forwards at the same time, so that the limited bouncing force is broken down into two directions.

Once you have a certain speed, you just have to jump up and use all the limited bounce power.

The above is analyzed from the perspective of mechanics.

From a physiological point of view, with the initial velocity of the run-up, when the last step is bounced, the muscles can be tightened to the greatest extent, just like the spring is compressed, and there can be a stronger ** force.
