Another wave of activity, which is also a very normal thing.

Now after Su Shen and Liu Xiang's coffee competition, activities are indispensable.

This is also the reality.

And they are also needed to promote it in China, which is what top stars should do, and it is incumbent on them.

After returning to Ersha Island, the days are no different from before the competition, because the winter training is still continuing.

You don't plan to go out so early yet.

Especially Su Shen, he really didn't plan to rush out so early.

He wants to finish it all and go to Europe to really have a good round of gold, oh no, it's the Diamond League.

The IAAF Diamond League, or Diamond League for short, is a global athletics series launched by the International Association of Athletics Federations (IAAF) in 2010. The event replaced the IAAF Golden League, which was previously limited to Europe, and the end-of-season prize was changed from gold bars to diamonds.

】

The Diamond League has a total of 14 stations, including Shanghai, China, with 32 individual events and a prize fund of 416,000 US dollars, and the top 20 athletes in each event are eligible to participate, and the athletes who win the championship and diamond ring will also receive the first place in the world ranking of each individual event recognized by the IAAF.

This is an expansion of the previous annual Golden League, which, together with the IAAF's annual Super Grand Prix and A-Prix events, transforms the former 6 Golden League events into 14 Diamond Leagues, with venues expanded from Europe to Asia, Europe and the Americas. Secondly, the competition events have been expanded from 10 men and women in the Golden League to 32 men and women, including men's and women's 100m, 200m, 400m, 800m, 1500m, 5000m, 400m hurdles, high jump, long jump, pole vault, triple jump, shot put, discus, javelin, men's 110m hurdles, women's 100m hurdles, etc. As a result of the significant increase in events, the number of competitions has more than tripled, so more athletes will be attracted to participate.

It should be noted that not all of the 32 men's and women's events will be held at every event, but each event will only appear seven times in 14 events, and the IAAF will negotiate with the event organizers on which one will be held, with the aim of reducing the pressure on the organizers and giving athletes more opportunities to choose from competitions.

In addition, the rules of the game and the scoring method are also completely new. Previously, only athletes who won all six Golden League events were eligible to share the million-dollar prize. The Diamond League, on the other hand, does not set a hard and fast rule on the number of times an athlete can participate in the competition, but determines the ranking of players in each event through points. The final winners will change from a maximum of 10 in the Golden League to a certain 32, and the total prize money will also range from one million dollars in the Golden League to $6.63 million in the Diamond League.

Among them, the top 3 players get 4 points, 2 points, and 1 point respectively, and the top 3 players in the final score are doubled, that is, 8 points, 4 points, and 2 points. The highest score in each event will receive a diamond trophy and a 4-carat diamond ring valued at $80,000. If the two players have the same number of points, the one with the most championships will be the first, and if they are still the same, then the results of the finals will be determined.

Of course, these are secondary.

Therefore, I won the championship of the Diamond League, that is, I got a big diamond ring and so on.

Maybe you can use this for marriage proposals, plus an Olympic gold medal, which is simply big and meaningful.

But the biggest significance is:

Wild card.

The IAAF has long stipulated that the overall champion of the Diamond League and the individual champion of the World Championships can get a wild card.

Of course, the Olympics do not have this power, and if you want to enter the selection, you can only score points.

Therefore, the Olympics is also recognized as the highest stage, and Bolt cannot have any preferential treatment.

But if you can beat everyone and win the wild card in the final finals this time...... Then maybe you can let all four people participate in the competition, or you can not participate in the selection competition, and give yourself more time to train.

This goal is still possible.

Because of Bolt's house, don't think about it, looking at his recent news, it is estimated that he has already started the "holiday" in advance.

It's almost impossible to get an athlete of Usain Bolt's type to work hard in a non-major year.

Mills couldn't do it either.

Therefore, Su Shen does not have any chance to win the wild card this year.

If it can be done, then the flower planter can play with four people, so as to avoid the regret that one person will be left behind every time.

Of course, to do all this, Su Shen himself still needs to be strong enough.

After all, this year's Gai Yin is not a strong horse.

……

Ersha Island.

Randy's passionate roar was everywhere.

I really don't know how this guy is so energetic even when he is so old.

Maybe it's really because I don't have a wife and no children? So energy is infinitely good?

Anyway, Liu Xiang came over and felt that Su Shen's side was really thundering and raining every day.

"Su, the moment when the supporting leg is off the ground, that is, the moment when the hip sending action is completed, the hip joint angle of the supporting leg should be about 202 degrees."

"Sue, the knee angle is about 151, and the hip angle of the swinging leg should be 90~100 optimally, and make the trunk, thigh, and calf form a moderate reverse arch."

"Sue, there are too many, there are too many anti-bows, the arc of the anti-bow is not as big as possible, and it depends on whether the speed and power of the swinging leg swing forward after kicking the ground can quickly turn to the next step. From the point of view of the mechanical conditions under which muscles work, technology is interrelated and restrictive. Sending the "hip" action is the key to leg push and swing coordination, and it is also the premise for completing a large and rapid leg exchange and active landing action. However, the hip delivery technique must be closely coordinated with the full extension of the support leg and the active forward swing of the swing leg in order to play its due role, which is too excessive and counterproductive. ”

Sue, look at this paragraph, before "extending the hips" or "sending the hips", the swing of the swing leg is characterized by the folding forward and upward swing in the early stage, and the forward and upward swing with a small increase in the angle of the knee joint in the later stage, but there is almost no "hip extension" or "hip delivery" action in this period; When the thigh of the swinging leg completes 3/4 of the swing action in front of the body, the knee angle of the swinging leg increases significantly, and at the same time, the amplitude of your pelvic rotation must also begin to increase. ”

"Sue, the change of the rear step length is very important, this time you look at the curve chart, it is clear that the swing leg in front of the body to complete the knee angle of the small amplitude and greatly increase the swing, here not only has a special effect on the back leg of the push and extension coordination, but also has a special impact on the pelvic rotation effect. So your hip delivery is a little insufficient, causing your stride to become smaller. ”

"Sue, don't forget that the push and extension of the back push leg makes the human body complete the forward flip process, and the force generated by the push and extension of the back press leg makes the human body obtain the support reaction force, and it can only ensure that the human body does forward and upward acceleration movement within a specific time. This piece is too excessive, don't be too deliberate. This is your own data from the lab, and this can only ensure that the human body accelerates in the horizontal direction and inertial motion in the vertical direction. This also shows that the change of muscle strength of the back pedal makes the change of human movement, which is the same as the muscle contraction of the swinging leg makes the change of the center of mass velocity of the swinging leg. Don't forget about it yourself. ”

"Sue, back pedal, or back pedal, this is a big problem. You come to see, in the process of back pedaling, the support reaction force obtained by the human body can ensure that the human body does forward and upward acceleration movement, you need to use the swing leg to complete a small increase in the angle of the knee joint swing, so that the link center of mass of the swing leg to the horizontal and vertical direction to do the acceleration movement. ”

"Su, the push and extension of the back leg can only ensure that the human body does the acceleration movement in the horizontal direction, and when the inertial movement is done in the vertical direction, it is still necessary to swing the leg to complete the greatly increased swing of the knee joint angle, so that the center of gravity of the swing leg can only be accelerated in the horizontal direction and inertial movement in the vertical direction."

"Su, the stride length is still not right, this is not the future, you are easy to run stiff when you run like this!"

Su, when the swing leg completes the swing of the knee joint angle to increase the slump, it is the critical period for the pelvis to complete the large-scale "fan" horizontal rotation, and the dynamic effect produced here can ensure that the human body continues to accelerate the movement in the horizontal direction, so as to avoid the acceleration of the center of mass of the body in some parts of the body and drive the acceleration of the center of gravity of the human body. Don't forget these things you said yourself. ”

"Su, this shot pays too much attention to the arc of the ground, and the landing is not done well, do you see if this is a credit card or a Xinhua dictionary?"

"Su ......"

Everyone sees Asia's No. 1 flyer, all of them are so rolled, and they take every training so seriously.

The rest have no excuses.

Who is now on Ersha Island who doesn't have a clear personal goal?

This is the "Asian Athletics Holy Land Ersha Island", not a place to come and retire.

Everyone wants to be good, at the very least, to be worthy of the name here.

You can't embarrass Ersha Island.
