Su Zu's Spring Festival at home was very short, and the head and tail added up to about ten days.

In addition to buying a mobile phone, Su Zu basically didn't have any big expenses, plus the bonus and salary for winning the 100-meter championship in the National Track and Field Championships later, adding up to 50,000 or 60,000 yuan. gave a bank card with 50,000 yuan to her mother Ye Qingmei, as for the motorcycle, after all, it was not possible to buy it for the time being under the opposition of her mother.

These tens of thousands of yuan, according to the law of the reborn, you have to find an investment channel and turn over 100,200,000. But the fact is that at this point in time, Su Zu, as a professional athlete, does not have much energy to study, and the second is to really find a suitable investment channel, put it for two or three years, and with this time, he has already earned an income that far exceeds the benefits of several times and dozens of times.

It is better to give it directly to parents, tens of thousands of yuan is not a small amount for rural families at this time. For Su Zu, the more important meaning is that he wants to reassure his parents. Tell them that he is no longer a child under Cheng Huan's knees, but that he has grown up, and it may be difficult to choose the path of competitive sports, but he has been able to gain a foothold in society, can stand on his own, and no longer needs them to carry this burden.

In the past year, the family's economic situation has been greatly improved, even if it is not as good as his tens of thousands of yuan. The biggest reason is that there is no need to provide for a person with all your heart, and you don't have to think about earning some living money all the time to cope with tuition, tuition and fees, living expenses, etc.

Quietly spent a Spring Festival with his parents, during which he visited relatives and visited the New Year, some were surprised to see Su Zu's personal changes, and some were envious when they heard that he had been selected for the national team. Between talking and laughing, no one could have imagined that there would be such a rapid change.

My cousin, who has always loved watching sports games, also teased a few words, saying that he saw Su Zu on TV, which aroused the curiosity of various relatives. However, athletes are too far away from ordinary people after all, and Su Zu's achievements and fame at this time are not enough to cause any sensation, but they are just occasionally chatting about one more thing.

On February 7, the sixth day of the first lunar month, Su Zu carried his bags, said goodbye to his parents, and left home again. Cars, trains, planes went around and around, and it was the Spring Festival again, and it took a day and a half to return to the youth training base at noon the next day.

In the afternoon, I simply cleaned the dormitory, had a good rest, and did not immediately start training. He also glanced at the athletics field when he first came back, and there were not many people returning to the academy at this time. There are only three or two athletes on the track and field who have been back for a few days and are doing some recovery training.

Since the end of the youth training convened last year, most of the athletes and coaches of the local teams have basically returned to their respective provinces and cities. There are a few seedlings who are selected by the national track and field team, including coaches, but compared to the total number of youth training, there are not too many.

During the rest and adjustment during the Spring Festival, Su Zu found that the original abnormal negative states had basically been eliminated, and they were all in moderate and light fatigue, and they recovered quickly.

On February 12, Lu Jianming also returned to the youth training base, and the first thing he did was to take Su Zu to the transportation hospital for weighing and physical examination.

"70.12 kilograms, body fat 10.5%, you went back to this Spring Festival to have a little moisturized." Looking at the physical examination report, Lu Jianming frowned, after coming back from the Spring Festival, Su Zu's weight and body fat have increased compared to before in the team.

"I practiced for a few days and then it went down." Su Zu didn't look too satisfied, his body fat increased and his weight increased, which undoubtedly increased the burden on his body and affected the speed and rhythm of running.

After all, the diet structure of going home for the Spring Festival is completely different from that in the team, not to mention the taste. No matter how delicious the nutritious meal is, few people can stand it for several months.

During this time period of the Spring Festival, in fact, it is also a headache for coaches. Because of such a grand holiday, there are no constraints, and there are few athletes who don't get fat and gain weight when they go home during the Spring Festival, and the body shape like Su Zu is very good, and it is not very obvious that he has basically grown meat.

Every year after coming back for the Spring Festival and weighing, one by one they are driven to the playground by the coach to reduce the meat first.

Su Zu has been repeatedly controlled, but because of the stagnation of training and the amount of food there, he still inevitably consumes too much energy. Last year, no one emphasized this in the training at the sports school, but this year, with the professionalization of the training, all aspects need to be paid attention to at any time.

"You have to recover quickly these days, time is very tight." Lu Jianming said with doubts.

The National Indoor Track and Field Championships is not too influential, but in domestic track and field events, it is also relatively high, and there are generally three stations in a competition. The main thing is that this competition is also a points competition for National Games players, and it is also the standard starting point for participating in large-scale international events such as the World Championships.

There are 11 events for men and women, including 60m, 200m, 400m, 800m, 1500m, 60m hurdles, high jump, pole vault, long jump, triple jump and shot put.

The participating units, local sports teams at all levels of provinces and cities, or independent colleges and clubs in their respective sports systems, can participate in the competition.

Athletes are generally required to register their individual results before commencing.

Su Zu participated in the competition in the name of the Southwest Sports Technology Institute, and his personal relationship is still attached to the Hedao City team, according to general, the qualification must be from the Ronghai Provincial team.

However, Lu Jianming understood that he did not have much intersection with the Ronghai Provincial Team, so he skipped this step directly, anyway, it was not the National Games, and after communicating with the Sports Technology College, his participating unit this time was directly the Sports Technology College.

This is also the norm in China, and it is also normal for seconded athletes to participate. It is a very distinctive system of "sharing achievements between the employer and the original talent delivery unit". This is also common for us, some athletes are obviously from Province A, but they may be wearing the uniform of Province B on the field of competition.

In fact, after athletes join the national team, even if they participate in the national team, most of the domestic events are still based on local provincial and municipal units.

Just think about Su Zu now, his relationship is in the Hedao City team, but he is also a member of the Ronghai Provincial Team, if he wants to participate in an event like the National Games, it must be in the name of the Ronghai Provincial Team.

After Lu Jianming learned some about Su Zu, the two went directly to the track and field to train.

As there is an event to prepare for the men's 60m at the Indoor Athletics Championships, the focus of training has also been adjusted. In fact, Lu Jianming's training plan, except for the original Su Zu's strength training, has been adjusted.

The 60-meter event is the shortest event in track and field, and it is also the event that most reflects the explosiveness and agility of human beings. Because the distance is short, there will not be too long a run, so the requirements for starting reaction and starting speed are higher.

Lu Jianming has analyzed Su Zu's running posture, his cadence is fast, and the acceleration is also fast, but because of the 100-meter change in the running method, the stride length has been improved by a certain amount, and the acceleration in the first half of the race will be slightly slower than before.

This kind of running method is aimed at 100 meters, and Lu Jianming is not ready to change it again in the short term, the more athletes need to adapt, the more chaotic it will be, but the focus is on improving Su Zu's starting reaction.

In sprint races, 0.10 seconds is considered the limit of an athlete's response to the starting gun, and if they are faster than that, they will be judged to be running fast.

But what is the most extreme starting reaction speed? 0.104 seconds. On September 14, 2002, at the French Grand Prix in Paris, American Montgomery set a world record in the men's 100m with a time of 9.78 seconds, when his reaction time was 0.104 seconds. In addition, Liu Feiren, who hurdles, also had an extreme 0.105-second starting reaction.

Putting aside the luck component of the gun run, this starting reaction is almost the limit of human beings, and in the field of sprinting, 0.01 seconds and 0.001 seconds mean more possibilities.

Su Zu's current starting reaction is within 0.2 seconds, and occasionally around 0.15 seconds, which is okay among ordinary sprinters, but when he really starts to compete with top masters, this is a bit insufficient. It is best to achieve a stable starting reaction speed of less than 0.15 seconds.

Especially in the 60-meter sprint race, you start 0.01 seconds slower, and you have to watch your opponent run in the first 10 or 20 meters, and when the speed is added, you will immediately reach the finish line.

There is a saying in sprinting that no matter how close the distance is or how fast the speed, there is nothing without a start.
