Tingting just smiled, to be honest, she wanted to be with Xia Xia more than White Tiger.

Although he is smaller than the White Tiger, he has a maturity and stability that the White Tiger does not have, and he knows how to distinguish priorities, he can bring a smile to Chu Xia, a man who has liked him for so many years and has not been distracted, it is really worth cherishing.

"Didn't you come to read a book? How do you feel like you're analyzing Xia Xia. Realizing that she was off topic, Tingting quickly pulled the topic back.

"Read books, read books." Fei turned his head and took a magazine and spread it on the table, and he couldn't read it anymore after reading a few pages.

Bored...... What is there to see in the entertainment industry.

Hongdao Arena

"Ye Yu took Fei and Tingting to go to the supermarket, so comfortable!" Looking at Feifa's circle of friends, Xuanwu, who was watching the game, said that he was very unhappy.

filmed several videos and swept up the private chat.

Because of the facility problem, they were delayed for more than 3 hours before it started, and the video was just sent to Feifei and called.

"Haven't you started the 100 meters yet?"

"Not yet, there was an accident with the electronic watch, it has just been replaced, and the next group will go to Molin." Xuanwu replied, this thing is still warming up, how can it be a game.

"We'll be right back." Tingting replied, and after hanging up the phone, the two ran downstairs to the beautiful IKEA, Ye Yu had been waiting for a long time.

"Let's go! Go back and watch the game! Stuffing the vegetables into the trunk, the three of them drove the car on the exclusive lane.

Arena

"Now we can see our Captain Qinglong, our Captain Qinglong is an athlete in North America!" The narrator explained with a grin.

"The man who has competed with the sprinters of Jamaica, the world's flying nation, let's wait and see his outburst!"

Jumping around, standing behind the starting block, looking left and right at the surrounding audience, don't you say back?

"Athletes, please!" The referee urged, there will be a finals later! Can't you prepare faster?

But they didn't dare to urge Mo Lin, this man who ran out of lightning could prepare for as long as he wanted.

After looking around a few more times to make sure there was none, Shanshan went up.

"Ready to go! Preparation! ”

Because the electric whistle was broken, they used the method of firing the gun, and knowing Mo Lin's situation, the referee moved the firing position back many steps.

With a bang, the eight people on the road were like tigers descending the mountain, menacing and chasing after each other.

Originally, he was going to run around and finish the job, but a familiar voice behind him stimulated him.

"Mo Lin, you dare to make garbage results, don't think about the old lady in the future!" Looking at Mo Lin's casual running posture, Fei's anger did not come to one place.

Suddenly accelerating and blinding the other people around him, his brain couldn't react at once, and he had already begun to accelerate and stride towards the end.

Probably because of the lack of effort in the early stage, the score was only 9.98, which was 0.01 seconds faster than the preliminary race.

"He's meowing, it's really floating!" Mo Lin who ran back with his teeth grinding.

His 100 meters were taught by the gods, and his running form was trained to the rhythm of Usain Bolt.

Mo Lin's start was impeccable, but the acceleration phase was a bit weak.

Some athletes have a 30-40 metre long stage, while others reduce it to 20-25 metres, depending on how good the start is. If an athlete has a problem with the start, then he will definitely want to reach the maximum speed as soon as possible, which has a good chance of ruining his acceleration. Conversion phase.

From 50 meters to 55 meters, this is the transition phase between Bolt's acceleration run and sprint run. He will reach his maximum speed at this stage, which is around 27 mph.

If you enter this stage 10 meters early, you will be able to sprint 30-40 meters at maximum speed.

Some of the most explosive athletes are able to reach their speed limit very quickly, often within 30 metres. But at the same time, it means that they will have a lot of trouble at the 70m or in the next 30m.

Mo Lin has stamina, so he will not slow down and be tired in the later stage.

Limit speedAthletes try to maintain their limit speed before the deceleration phase, as they have to slow down the moment they hit the line.

The reason why Mo Lin was asked to learn the skills of Bolt and the Jamaican athletes in sprinting is because the advantage of Jamaican athletes in sprinting is that they have a large stride, and all other athletes can't compare with him, which is a skill that Old Man Mo hopes Mo Lin will learn.

But in addition to this advantage, other characteristics are not recommended by the old man. Usain Bolt will be able to maintain his limit speed for as long as possible, even if there will be a limit. Especially in the last 20 meters, when he occasionally looks around and gradually starts to slow down, he will always look at the timer habitually.

In the eyes of those who are not very proficient in the 100 meters, they all believe that when the body's center of gravity shifts over the vertical plane of the human fulcrum, it enters the stage of supporting leg back and forward swing.

At this time, the knee joint of the swinging leg exceeds the supporting leg, and under the coordinated contraction of the iliopsoas muscle, rectus femoris, sartorius muscle, tensor fascia lata and other muscles, it begins to swing forward and upward quickly and powerfully, and drives the pelvis on the same side to send forward, so that the thigh is lifted to a horizontal or lower horizontal position, and the supporting leg swings forward and upward quickly and forcefully under the coordinated contraction of the gluteus maximus, biceps femoris, semitendinous semimembranosus muscle and triceps calf muscle under the cooperation of the swinging leg positive forward swing.

With the active forward swing of the swinging leg, the supporting leg quickly and forcefully extends the hips, knees, and ankles in succession until the soles of the feet are pushed off the ground.

At the end of the back pedal, the angle between the legs of the support leg and the swing leg should be greater than 100 degrees, and the line between the support leg support point and the hip joint forms an angle of about 47~50 degrees with the ground.

In the stage of back push and forward swing, it is now believed that the knee joint of the swing leg exceeds the support leg and begins to swing forward and upwards quickly and powerfully, and drives the pelvis on the same side to send forward, the thigh is lifted to about 15~20 degrees from the horizontal plane, and the support leg is actively swinging forward with the cooperation of the swing leg, and the hip, knee and ankle joints are quickly and effectively extended in turn until they are kicked off the ground, forming the coordinated action of the support leg and the swing leg.

At the end of the back pedal, the angle between the two thighs of the supporting leg and the swinging leg is about 100~110 degrees; The line from the fulcrum of the supporting leg to the hip joint is about 55~60 degrees from the ground.

It can be seen that the back and forward swing phases of modern sprints emphasize the details of the action even more. In terms of angles, the range is smaller and more specific. For example, in the past, it was required to be lifted to the level or slightly below the level, but now the thighs should be lifted to an angle of 15~20 degrees with the horizontal plane, which not only saves energy, but also shortens the time.

Mo Lin's running style is a fusion of Bolt's running style, and it also has various details of modern sprinting.
