Standing long jump was slightly injured, who knows the force analysis of standing long jump?

At present, the main thing is to recuperate. You don't have to watch the game and rush to exercise. Usually face it with a heart.

Because you have the foundation. So there's no need to rush. You can't sit at home.

Because you're okay walking. No fractures, no bruises, no swelling. When the eye can't be recognized, the ** is broken.

It is not recommended that you go to the hospital. I also practice sports. Training is inevitably bumpy.

Start by laying your leg flat and rubbing the injured area with your hands. Rub until heated. Then squat.

Try to keep this position as soon as it hurts. in kneading. Do some basic exercise.

Stretched the body open. No problem. Take it easy.

Good luck.

I definitely can't practice again in the afternoon!! If you practice, there will be problems

Today's Monday and Friday exams、How much will it affect it、There are still a few days before the exam that shouldn't be practicing.、、、

But don't worry too much, it shouldn't be a big deal

You may just have a momentary pain in your knee

I'm too afraid that it will affect your grades, don't practice these days

If you get hurt again, it's completely over

First of all, don't be in a hurry!

You said that you have no problem walking, it hurts when you squat down, and the problem is not very big.

You rub it with your hands! You can practice today, but take good care of it. You can't get hurt anymore, sports will inevitably stumble, but you can also be too hasty, otherwise it will backfire, in addition, don't practice too much these days, feel for yourself, just be moderate, believe in yourself!

It should be a dislocated kneecap, it's not a big deal, it's better to rub it often, it will recover on its own, I used to have something similar, it won't be fine in a few days! It's best to tell the teacher in the afternoon, don't let your knees misalign again, Friday should be fine!

I must practice I practiced 3 steps on 1 week and got my feet to it. Our PE teacher said no. If it hurts, you have to practice it. That's why I support you to practice when you hurt.

It's not a grunt, if so, there should be something.

Gotcha, raise. It definitely hurts. Try not to overexert yourself. Walk too much.

Hurt muscles and bones for 100 days, pay attention to rest, pro.

See entry for details: London 1908.

On July 13, 1908, the 4th Olympiad was officially opened. At the opening ceremony, athletes enter the stadium in a national line, and many countries send selected national teams to participate. Archers William and Charlotte Dodd became the first brother and sister to win medals.

The 60-year-old became the oldest athlete to win an Olympic gold medal, winning the men's deer singles individual event. The 1908 Olympics also saw diving and hockey events for the first time. The sportsmanship was evident in the middleweight wrestling final, which was between Martensen and Anderson, and was allowed to be postponed for a day to allow the lightly injured Martensen to resume the match, and Martensen won the gold medal.

Yuri won his third time in the standing long jump and standing high jump, becoming the only athlete in Olympic history to win eight gold medals in individual events. The dramatic end of the marathon caught the attention of people around the world, and in the 42km run, Italy's Pietri was the first to enter the stadium, but he fell on the track five times and was disqualified when he crossed the finish line with him.

For the first time, the Olympic Games stipulated that all delegations at the opening ceremony should dress uniformly and guide the following teams under their national flags. Great Britain took first place in the gold medal table (56) and the United States finished second with 23 gold medals, with the marathon and 400m running being the main events of the Games, which took place on 24 July. Italian player D

Petrie fell several times in extreme fatigue, got up several times, and finally reached the finish line with the help of others. Although he did not win the championship, he was in a moving spirit and won a special gold trophy from the Queen of England. After the London Olympics, the International Olympic Committee (IOC) reformed its refereeing work, stipulating that in the future, refereeing work will no longer be arranged by the host country, but will be planned by the IOC and international sports organizations.

The 1908 London Olympic Games, the fourth Olympic Games were held in London, England on July 13, 1908, and 22 countries participated in the Olympic Games. Finland, Turkey and New Zealand (part of Australasia) are participating in the Games for the first time, while Great Britain has won 145 medals, the United States has won 47 medals and Sweden has won 25 medals.

In 1906, Rome, which was originally scheduled to host the fourth Olympic Games, applied to the International Olympic Committee, but due to Italy's financial difficulties, it could not afford to build stadiums and announced that it would give up the right to host. The International Olympic Committee (IOC) had to work with Great Britain on an ad hoc basis to relocate the Games to London. In just two years, the UK** has shown amazing productivity.

They quickly built a 10,000-seater, 70,000-seat "modern" stadium in a barren bushland in London's West End, known as the "White City" stadium, in a barren bushland in the West End.

The 4th Olympic Games were held in London, England from April 27 to October 31, 1908.

It was also the first time that London, England had hosted the Olympic Games.

At the moment before the foot leaves the ground, the force analysis gravity g is vertically downward, and the elastic force n1 of the ground to the foot is vertically upward, g=n1 and in the opposite direction. The kicking force of the foot to the ground n2 obliquely backward can be divided into two components, horizontal backward force n3 and vertical downward force n4, if the angle between the direction of movement and the ground when the person jumps is a, then n3 = n2 * cosa n4 = n2 * sina corresponds to two elastic forces t3 and t4 horizontally forward and vertically upward, t3 and t4 The resultant force of t3 and t4 is t2, and the size is the same as n2 The direction is opposite Therefore, the person moves forward and upward, that is, the direction of t2.

From the soles of the feet to the ground (friction, pressure, support) (ankle force, colleague's arm swinging back and forth) to knee push (support) to hip joint push (stand up, form an arch, air gravity, forward momentum, air resistance), abdominal tuck on the ball of the foot (friction), knee bending, squat (gravity decreases).

If you need to say one, it is the ankle joint, because the ankle joint needs to bear the weight of your entire body when it lands, as well as the momentum, which is a test for the ankle joint. In addition, the ankle joint can be sprained due to your poor landing movement.

I'm good at that!! Running is definitely not a practice! You can't do the long jump (because your knees hurt when you're half-squatting, and you have to half-squat for a regular long jump) It's okay to sit and bend forward!

Because it doesn't use the area of your knees, but it can't be excessive, in moderation) (it uses the tendons below your knees, which is why you can't overdo it).

Ice compress is the most useful, don't exercise vigorously these days, rub safflower oil every day, relieve menstruation and invigorate blood, move slowly after swelling, and rub Shuangfeiren if it still hurts during the exam!! It's OK to wipe it hot.! I was like that before.
