The sound of puff footsteps sounded quickly on the track and field track, and a figure passed quickly.

Loren Seagrave took the sprint data of Suzu that his assistant had just counted through the electronic recording instrument, and bowed slightly. Then he beckoned to Su Zu, who had stopped in front of the finish line not far away.

"Sue, I think your stride should be redesigned."

Loren Seagrave pointed to a data table in his hand and spoke to Suzu.

"You're longer than the average Asian, about the same height as a black athlete, and I found that you can rely on a big stride in the second half of the 100m to increase your speed."

Suzu leaned over to Loren Seagrave and glanced at the record forms in his hand, many of them were technical terms, and there was no problem in conversing with his English level, but some professional reports were still not enough.

However, a few items in the table are written more clearly, which are all relevant data such as the starting reaction time, the acceleration stage, the mid-way running stage, and the final sprint stage.

"Mr. Seagrave, do you already have an optimization plan?"

Su Zu asked, sprinting technique is closely related to the level of sprinters, and he has been in IMG Academy for more than two weeks, in addition to training, he is also constantly polishing his sprinting skills.

This change is very subtle, sometimes just the size of the angle of the swing arm, and after the posture is fixed, it can make the running lighter.

"Sue, first you have to understand the meaning of stride. Stride length is governed by the explosive force of your stride or the amount of time it takes to touch the ground, and the stride length is affected by the force of the angle between your support leg and the ground. Loren Seagrave pointed to Suzu's thigh and made a running stance, "When you swing your foot to the ground, it creates resistance that slows you down, but when you increase the stride you length, it actually reduces the stride length." The best way to increase stride length is not to change technique or apply more force to the ground. When applied to the ground with a large burst of force, i.e., increased cadence, the stride length naturally increases. ”

Su Zu nodded, he has recently accepted a lot of Loren Seagrave's sports concepts, which is supported by the research of the entire college, and has many unique insights in sports sports and ergonomics.

To put it simply, improving stride length is not just a big stride, or a hard leg press similar to a triple jump, because when using these two methods, the body is also doing work, which will produce a certain amount of resistance, which will offset the advantage of stride length. The increase in stride length is still improved by explosive power and ground contact instantaneousness, and the cadence is further optimized.

"And one more, Sue, it's important to keep your center of gravity!" Loren Seagrave said in an emphatic tone, "You can keep your center of gravity a little better during the acceleration phase, and pay attention to the tilt." The tilt is easy to accelerate, the greater the tilt, the faster the acceleration, once the maximum speed is reached, do not ignore the effect of the tilt. ”

Loren Seagrave said as he instructed Suzu in his demonstration.

In sprinting, the athlete starts and accelerates with the center of gravity in front of the tilt, and every time the athlete successfully pushes the ground, the athlete increases the speed until the athlete reaches the athlete's maximum speed. As the speed increases, the acceleration decreases, and the athlete will slowly reduce the inclination of the body on the track, and when the maximum speed is reached, the posture of the entire body is vertical.

In the sprint event, Li Zhizhong's comparative advantage is strength training, and the optimization of sprinting techniques is a little rough. Later, Su Zu's sprinting skills improved, to a certain extent, from the guidance of Yuan Guohua during relay training.

However, Su Zu did not listen to Loren Seagrave's technical improvements, and completely followed the other party's routine. Instead, according to the experience of one's own body, absorb the advantages, and experience and improve it personally. These technical improvements are not instantaneous, but require repeated running exercises to consolidate the body's memory.

After talking about the previous things, in terms of running technique, the two discussed the essentials of swinging the arm for a while, such as whether the fingers are extended or flexed and extended when swinging the arm, and the situation of taking a long stride when feeling tired near the finish line in the final sprint.

"By the way, have Su, Li and Zhang left the academy?" Loren Seagrave began to ask after the discussion.

"Yes, my two coaches need to go to Baylor University in Texas, and maybe we'll have a bunch of players training there."

"Why, they can come to IMG?" Loren Seagrave had a question typical of old American doubts.

"I don't know about that."

Su Zu said that he didn't know, but he had to complain in his heart, it's not that the cost of your IMG is too high. Li Zhizhong and Zhang Pingqiu went to Baylor University mainly to communicate with the university, and Yang Guangzong will arrive after the Spring Festival for half a year of closed training. Although I can't say how good the level of training there is, it is also under the guidance of Michael Johnson, a leader in the field of athletics.

These hours of training, Loren Seagrave and Suzu get along and have a good time. First of all, Su Zu understands English, except for some professional terms that are not so able to understand the meaning, and it is very good to communicate without barriers in stride.

The second is that Su Zu is mentally mature after all, and he understands many things as soon as he hears them, and he doesn't need to explain them repeatedly, and he can understand Loren Seagrave's intentions and implement his training methods. In addition, although Su Zu is not very old, his achievements are amazing enough, and his knowledge of kinesiology and training concepts have also given Loren Seagrave a lot of ideas.

The experience of a top athlete is a great asset in itself.

For Li Zhizhong, Loren Seagrave also admires it very much. He is 55 years old this year, but he still maintains the intellectual curiosity of a young coach, and he has benefited a lot from the exchange with Li Zhizhong.

A perfect training system is never something that can be achieved behind closed doors. In later generations, Chinese track and field also implemented the strategy of "going out and inviting in" on a large scale, learning from each other's strengths and constantly deepening and optimizing talent training.

"It's almost time, it's time for us to go to the fitness center." Loren Seagrave looked at the time of his watch and said to Suzu.

"Okay." Suzu nodded, picked up the coat next to him and put it on, packed up his things and walked with Loren Seagrave to the IMG Academy's physical training center.

As the ace coach of IMG Academy, Loren Seagrave can't just coach Su Zu alone, and only have a fixed three or four hours of technical guidance every week, and the rest of the time he has to go to the physical training center to guide other athletes in physical training.

Of course, physical training is all together, and many of these athletes, like Su Zu, are top figures from all over the world in various fields.

At the Strength and Conditioning Center, Suzu's strength training has entered a new way.

This strength training program continues throughout his year-round competition, with a focus on strength training in the first few months of each year.

Start with lightweight, gradually increase the weight and reduce the number of reps, so that the muscles can exercise more efficiently.

In addition, as the training program progresses, muscular endurance should also be developed. Muscular endurance training is a circuit training that involves lifting a solid ball or isometric exercises to hit a certain resistance with maximum force.

The last and most important thing is the training of explosiveness. The power of sprinting is primarily about explosiveness, which is indispensable throughout the year and season.

The method is to complete the explosive upward lift quickly with the first amount, which is simply similar to high flips and pushes, but each time there is a requirement for speed. Other exercises such as bench press, snatch, hard press, one-leg squat, front and back leg press dumbbell are all listed in a detailed training plan.

Su Zu continued to carry out this strength training method, and then optimized the subtleties according to the feedback and weaknesses of his body.

At this time, in the physical training center, Su Zu was doing negative bell stool exercises. This action is very simple, the athlete carries the barbell on his shoulder, and then maintains his body balance, constantly stepping up the steps about the height of an ordinary stool in front of him.

Just as Su Zu was busy training, he didn't know that at this moment, not far from him, someone was watching him.

"Maggie, do you have a crush on that Asian?"

It was a black female athlete who spoke, and she noticed that Sharapova seemed to be wandering over the other person several times as she was observing.

IMG has a lot of gyms, but this training center is hosted by Loren Seagrave, and in addition to being hired separately and privately, many big-name athletes are also willing to come and train together to receive guidance from Loren Seagrave.

"Don't you think it's interesting to meet an Asian man?" Sharapova smiled, "I'm going to invite him to my celebration party." ”

This tennis star who dared to shout "I like to go out with different cultural backgrounds and different people" in later generations is still young, but the domineering and strong in his bones have been fully revealed after the baptism of Wimbledon.

The black female athlete shrugged her shoulders, although the other party's figure looked quite good, but this kind of ascetic and stuffy Asian face was not his cup of tea at all.

While speaking, when Suzu stopped training and rested, Sharapova had already walked in front of Suzu.

"Hey, Sue, I see you're training here alone? What about your coach? ”

"They went to Texas on something and will be back in a few days." Su Zu raised his head and looked at Sharapova in front of him a little strange.

These days have been met several times at the strength and conditioning center, after all, Sharapova has been training with Loren Seagrave just like him.

"Sue, I'm here to invite you to my celebratory party the night after tomorrow?"

"Party?"

"Remember to come then." After Sharapova finished speaking, she didn't wait for Su Zu to agree, and turned around and left directly.

Although she is a hairy girl, she grew up in the United States, and Sharapova is actually not much different from an American. It's all too common to invite a boy she's seen to a party. It's just that with the continuous improvement of her grades, her status is not something that ordinary people can qualify for.

"I've been attacked?!"

Su Zu was still a little stunned for a while, it is not uncommon to be invited by his sister, the two are about the same age, but compared to the coffee position, your tennis star is a lot stronger than me, a newcomer who has just emerged in the field of athletics, where did this strange idea come from.

However, Su Zu also knows something about it, and it is just an invitation to a party, and it should be unlikely that people will take a fancy to him.

Here Su Zu also underestimated the Olympics and his influence, in the 2004 sports program, there are not many Chinese who can really be remembered by Lao Mei. Among them, it is needless to say that Da Yao, who competes in the NBA, the other is him.

Compared with Liu Yangyu's 110-meter hurdles championship, in the traditional American sports world, he Suzu is more valued. He challenged a truly strong event, and the loss of the men's 4×100m championship at the Olympics was an accident in the eyes of many Americans, not to mention that it was a group of Chinese who won the championship. And the core athletes, in addition, won the men's 100-meter third place and the 200-meter runner-up.

With a time of 9.89 seconds, there are not many American athletes who can run at present, and it is also ranked very high in the entire history of track and field.

This year's American track and field have called for Su Zu to award the "Owens Award", of course, this possibility is basically zero, the first in the whole of Asia to win this award, in 1994, the Oriental Shenlu luckily won once, and few non-American athletes won it since.

Of course, track and field isn't a big hit in the U.S. itself, but the athlete news about the Red Empire is well worth the hype.

With the blessing of this foreign background, good sports results, and a completely ascetic appearance, it can still arouse the interest of some women who are cheerful and strong in themselves.
