On a track and field field at IMG Academy, Su Zu took a standing starting posture, leaned over, leaned forward, swung one arm back, and one arm naturally hung down to touch the track.

Li Zhizhong stood next to Su Zu, watched Su Zu put on a starting posture, reset the stopwatch in his hand to zero, and shouted loudly: "Prepare - run!" ”

The sound of puff footsteps sounded quickly, and the sprinters started and accelerated at close range, full of indescribable power and speed, and the sudden burst seemed to be like a sports car that refueled in an instant, and it rushed out with a "buzz".

After starting from Suzu, Li Zhizhong followed to the finish line not far from the starting gear. On the edge of the finish line, Zhang Pingqiu stood at the inner edge of the runway, also holding a stopwatch in his hand, watching Su Zu running around the 400-meter standard track from a distance.

Tick tock...... Dozens of seconds passed in a flash, and Su Zu, who started from the starting line of the corner, had already completed a lap and crossed the finish line. At the same time, Li Zhizhong and Zhang Pingqiu also pressed the stopwatch in their hands.

"43.22 seconds!" Zhang Pingqiu reported the time of the stopwatch in his hand.

"43.17 seconds!" Li Zhizhong glanced at the stopwatch, and then said the results of this group, with a satisfied smile on his face, "It's not bad, it's improved compared to before." ”

"Yes, both groups are doing very well." Zhang Pingqiu also laughed and replied.

It is very rewarding to follow an athlete whose training performance is always improving, and you can see that the other person is improving every once in a while. Effort pays off, and it's not so easy for athletes who reach a high level on the training ground.

"The speed and endurance training is still very effective, and I think that if it is replaced by an electric record, it will almost be able to break the domestic 400-meter record." Zhang Pingqiu picked up the record book, filled in the data results of this group, and looked up at Li Zhizhong and said.

"When the level is reached, it is not difficult to break the domestic 400m record." Li Zhizhong nodded slightly, "The key is that this training method can improve the speed in the second half of the race, Loren Seagrave suggested that we should pay attention to speed and endurance, although we have trained before, but we still haven't taken it seriously." ”

"100 meters is 95% anaerobic metabolism, 200 meters is 90% anaerobic metabolism, 10% aerobic metabolism. By the 400 meters, the aerobic ratio is 20%-30%, and the data they give is said to have been tested by a large number of athletes. ”

In the past few months, Zhang Pingqiu has been studying at IMG Academy except for a trip to Texas with Li Zhizhong, which is also an eye-opener. Needless to say, all kinds of high-end instruments and equipment, the key is that many training concepts and training methods are supported by science and technology, and they are very refined, and a training program will not simply stay on the surface.

For example, the training method provided by the other party is very fine, general speed training (50%-70% of the maximum speed), there are three kinds, > 100 meters, > 200 meters, > 80 meters, this is an aerobic type of sprint speed training, each group recovers for 30 seconds, and a total of about 1,000 to 3,000 meters.

There are also anaerobic type speed trainings, 20-80 meter sprints for anaerobic and lactic acid, in addition to several training sessions for speed endurance and specialized endurance.

It can't be said that these training methods have not been exposed to before, after all, sprinting training methods always can't escape those few. But few are as precise and meticulous as others, from the exercise goals of each set of training are aerobic, anaerobic, mixed, glycolysis, lactate tolerance, or rest time intervals, respiratory rate, blood oxygen supply, etc., there are very clear reports. From the goal of training, to the desired results and the way to take, many things are in the hands of an experienced coach and can be seen at a glance.

And during the time that Li Zhizhong and Zhang Pingqiu were discussing, on the runway, Su Zu was panting with his waist crossed, frowning from time to time, revealing a bit of muscle soreness and pain.

The feeling of running 400 meters and running 1200 meters is completely different. After only two tests of 400 meters at full speed, Su Zu felt a little tired and needed to make a transition before he could gradually recover.

After walking around the runway for a while, Su Zu felt that his qi and blood were gradually calming down, so he found a folding chair and sat down on the sidelines, kicked his feet left and right, and directly took off his spikes.

His training at IMG was directed and taught by Loren Seagrave at the beginning, and in the later stage, various training plans slowly came out, and Loren Seagrave came relatively rarely, mainly implementing his own coaches Li Zhizhong and Zhang Pingqiu, counting various training data and arranging time.

The intensity of the training has also increased compared to before, mainly due to the reduction in training time. Some of the same endurance and strength trainings that used to take two hours to complete are now required to be done in an hour and a half.

However, this extra time is not idle, in addition to free activities to recover, there will also be some flexible stretching training, similar to some yoga movements.

"I'll go back to China the day after tomorrow, and I won't train tomorrow, do you have anything you want to buy?" Li Zhizhong looked at the various test data records of Su Zu collected by Zhang Pingqiu, walked to Su Zu's side and said.

"There are still a lot of good things here, and they don't have to sell them in China now." Zhang Pingqiu put away the recorded document and said. In 2004, the world's factories are still on the rise, and there are not so many purchasing agents on the market.

"There's not much you want to buy." Su Zu shook his head, "But if you go out tomorrow, you can take a look around together." ”

The winter training at IMG has been more than three months, and it is now February 1, 2005, and the Spring Festival is just over a week away.

Su Zu leaned back on the folding chair and squinted his eyes slightly, he was still quite satisfied with this winter training, and at this time, the various attributes on his system panel had increased to varying degrees.

Name: Su Zu

Age: 17

Profession: Athlete

Physical fitness: 27

Agility Qualities: 27

Strength qualities: 29

Reaction qualities: 20

Endurance qualities: 21

Flexibility qualities: 20

Potential: 11.7%

[Negative Status ......]

……

Among them, the flexibility quality has risen the most, except for 1 point for special stretching and flexibility training, the other 3 points are through the addition of points.

Flexibility seems to have little to do with Su Zu's training items, but after the recent growth, it is obvious that he has a much stronger control over his body, and some training that is particularly easy to cause joint fatigue, such as heavy weight squats, etc., is also much better. These are implicit effects, and you can see the high and low through the data, but the effect of the effect is difficult to judge numerically.

In addition, 1 point has been added to the agility quality, and after more than three months of training, the potential points obtained are only these 4 points. The other physical strength, strength and endurance gains by 1 point come from the effect of training.

And during this period of training and diet, he obviously looked much more lean than in October 04. With a height of 1.85 meters and a weight of 77.5KG, he has obvious muscle lines, and he looks slender and strong, like a leopard.

While a few people were resting and chatting, a sudden sound of footsteps sounded outside the runway.

Loren Seagrave suddenly walked up to several people with a white man in leather shoes.

"Mr. Seagrave, I haven't seen you in a few days." After seeing the two of them appear, Li Zhizhong smiled and took the lead in greeting.

"Li, are you blaming me for not doing my duty?" Loren Seagrave replied with a smile, and then said with some apologies, "I've been really busy lately, and the college arranged for me to go out for a business exchange and promotion event. ”

A coach who can be in charge of a place like IMG Academy and have a reputation for it has a much higher emotional intelligence than most people think. No matter what he thinks in his heart, an old man in his fifties can hold a high position in a commercial organization, and he will not be seen in the slightest.

"I'm here to introduce you, this is Matthew Straw, he's a sports agent at IMG, and I'd like to talk to you." Loren Seagrave introduced the white man behind him to the crowd.

"Sorry to interrupt your training. Su Zu, you are an athlete I admire very much, as well as Coach Li Zhizhong and Coach Zhang, hello. ”

To the expectations of Su Zu and several people, this white man was fluent in Chinese as soon as he spoke, except for a little weirdness in his tone, his words were clear.

"Do you still speak Chinese?" Zhang Pingqiu blurted out in surprise.

"Chinese is a broad and profound language, and I have the privilege of learning some of it." The white man said modestly, "My name is Matthew Straw, you can call me Matthew, and this is my Chinese name." ”

"So, Mr. Matthew, do you have anything looking for us?" Li Zhizhong looked at Su Zu quietly beside him and asked.

"I'm sorry, I'm a bit presumptuous on this trip, I should have invited you beforehand. But I've heard that you're going to be returning home soon, so I'm going to have to come and meet you first. ”

Matthew Straw's posture is very low, and many Western negotiation events will be invited in some more formal places in advance, and it is rare to suddenly appear directly in the track and field.

Su Zu looked at the other party's eyes and kept rolling on him, and with Loren Seagrave's introduction, he had already guessed a little.

Sports agent?!

IMG is one of the world's leading sports, entertainment and media companies, and although it was not as big as it was in 2004, it still has a tentacle that extends into various fields. Moreover, in addition to sports schools, the business of this economic company has gradually expanded by relying on the business of sports stars.

"Su Zu, and Coach Li, I took the liberty to come here this time in the hope of being able to negotiate with you about Su Zu's sports agent business."

Matthew Straw went on to say that it was obvious that he was also a China expert, and although his attention was mainly on Su Zu, he did not neglect Li Zhizhong, and knew the relationship between the two very well.

"If it's possible......" Matthew Straw pointed to the surroundings of the athletic field, "we can talk about it somewhere else." ”
