Zhong Jing's results made the coach very excited.
If Zhong Jing can maintain this result in long-distance running, there is a lot to be done.
"Okay, okay", the coach's face is full of smiles.
If they can win the 5000m championship, it will be a landmark victory. It may be recorded in history.
Even he will benefit a lot shallow
"My grades are not bad." Zhong Jing moved his body, then took the water handed over by the assistant and drank it. He was indeed a little thirsty.
This thing is very wasteful for the body.
"Zhong Jing, let me correct your mistakes in running." The coach walked out of the car and came to Zhong Jing's side.
"The way you ran just now not only wastes your energy, but also affects your speed." Then, the coach showed Zhong Jing the correct way.
Running looks very simple, but it is actually a technical activity.
Many people practice it not only to increase their physical strength, but also to increase their muscles. In addition, he also learned skills.
These were learned by track and field athletes of all ages.
Zhong Jing tried it but didn’t feel anything.
"You may not feel anything now, but if you run far and for a long time, this will have a greater effect. You can do whatever you want for sprinting." Seemingly seeing Zhong Jing's disapproval, the coach comforted him.
""Yes." Zhong Jing nodded.
He has the ability to remember photographs, and these technical things are easy to remember.
The rest is turned into muscle memory.

After resting for a while, several people came to another venue, the javelin training venue.
Javelin is an event in track and field.
The athlete throws the javelin after a run-up.
One of the throwing instruments used in track and field sports, the gun shaft is made of wood (or metal), thick in the middle, thin at both ends, and has a pointed metal head at the front end.
An old-style weapon with a spearhead mounted on one end of a long pole that could be thrown and used to kill enemies or hunt.
The javelin originated as an early hunting tool for humans. It was made by grinding and sharpening both ends of bamboo or wood. It can be pierced or thrown. In later generations, it also evolved into a type of combat weapon.
Javelin throwing is a relatively complex multi-axis rotation event. Its complete technique is to hold the gun on the shoulder and gain momentum through a pre-run-up and throwing step, and then use the explosive final force to act on the longitudinal axis of the javelin to throw the javelin over the shoulder.
In ancient times, the competition method of javelin was not only about distance, but also about accuracy.
It originated from the activity of ancient humans using spears to hunt wild animals. Later, spears developed into weapons of war.
In 708 BC, it was listed as one of the pentathlons in the 18th Ancient Olympic Games. The modern javelin sport began in European countries such as Sweden, Greece, Hungary and Finland in the 19th century.
In 1792, javelin competitions began in Falon, Sweden. At first, the wooden javelins used by athletes were as thick as the front and back. In the early 1950s, American javelin thrower Held developed a wooden javelin that was thin at both ends and thick in the middle, which extended the time the javelin flew in the air, so it was called gliding. javelin.
In the 1960s, Sweden manufactured a metal javelin, which made the javelin more gliding and greatly improved sports performance.
The javelin may be made of metal or other suitable similar material.
The men's javelin weighs 800 grams and is 260 to 270 centimeters long; the women's javelin weighs 600 grams and is 220 to 230 centimeters long.
During the competition, athletes must throw the javelin from above the shoulder with one hand, and the tip of the javelin must fall within the angle line of the throwing area to be effective.
Men's and women's javelin were included as Olympic events in 1908 and 1932 respectively.
Most regions or ethnic groups in our country generally use javelins as tools for productive labor and weapons for self-defense.
Most of the javelins used by ethnic minorities in Yunnan, Guizhou and other southwestern provinces are light and small and have extremely sharp iron arrowheads. The spear shafts are mostly made of bamboo and less of wood, rather than iron. Some spearheads are made of sharpened bamboo wood, which is very convenient and economical, but the effectiveness of killing enemies is not reduced. The Miao and Yao people sometimes apply poison to the tips of their spears, and the life of the winning bidder is at risk. Even if the javelin is not poisoned, its long range, fierce shooting power, and accurate throwing can still penetrate the chest and head.
The javelin was a powerful weapon in ancient times, similar to today's shooting competitions and fencing competitions, both of which evolved in ancient times.
Of course, it can't be exactly the same.
And many evolved based on Western activities.
Fencing competitions are about Western swords, not antique Tang swords.
······
There are many venues for javelin and they are quite open.
This thing is very lethal.
If not maintained well, it may kill someone.
This turned into a major accident.
So, be sure to pay attention to safety. _Feilu reminds you: three things about reading - collection and recommendation
