"Master, I still want to give it a try."

Su Zu is very clear about the current situation, and the various attributes in his current system, such as physical fitness, agility, and strength, have grown more and more slowly after reaching 30 points.

It's not that he doesn't grow at all, for example, if he stays in the gym a little longer, and the weight is added, the strength will definitely be able to break through 30 and improve again.

But judging from the current situation of his body, the strength quality has increased again, and the muscles of the body will undoubtedly become bloated, even if the agility quality or several other qualities are improved at the same time, the speed increase brought by it is not as good as it is now.

On the contrary, reaction, endurance, and flexibility can be improved to a certain extent, but the qualities complement each other, if the endurance quality is improved, the physical fitness will increase together, but the agility and strength quality will also face a certain decline.

This is what the structure of the human body determines. A marathon runner with excellent endurance cannot be a muscular sprinter.

A sprinter needs explosive power and muscles, and his endurance cannot be as high as that of a long-distance runner.

Su Zu knew very well that if he wanted to break his current results again, from the perspective of training, he must optimize his skills and enter a new stage and field.

This may lead to a decline in results in the short term, but in the long term, it is a must in the face of the upcoming Jamaican team.

Li Zhizhong looked at Su Zu with both relief and some worry.

The gratifying point is that Su Zu is still able to maintain his original intention to continuously optimize technology to this point, and has the perseverance to surpass himself and pursue stronger.

This is especially rare for athletes, especially those who have achieved results.

The worry is that Su Zu's change is likely to not achieve the expected effect, but the current training measures he has taken are basically the experience of his predecessors, and the sub-plateau training comes from Eastern Europe, even if it is water training, it is also one of the training methods that are widely spread abroad.

If Su Zu's rhythm changes this time, his performance declines, and Li Zhizhong is not worried about entering 10 seconds or 9.90 seconds, but if he wants to be able to run 9.80 seconds again, or even within 9.70 seconds that Su Zu is pursuing, it is completely unknown.

"Su Zu, you have to think about it, you change the rhythm now, optimize the technology, and if you want to return to the original level, it may take half a year, a year, or even longer." Li Zhizhong voiced his concerns.

"Hmm." Su Zu nodded, looking at the large training ground of the Haigen base outside the track and field, "Let's try again, Master." I think I should be able to do 44 or even 43 steps, so if I can maintain my cadence or even drop it too much, hopefully I can go further. ”

"Okay, let's see how it works." Li Zhizhong did not block Su Zu's thoughts, as a world record holder, it is a manifestation of an athlete's gradual maturity to have such a pursuit of self-breakthrough.

thought about it for a while and then said, "By the way, you go back and pay attention to the time, there is a rehearsal time for the Spring Festival Gala." ”

Su Zu nodded lightly, his eyes were slightly sloppy, but he didn't seem to listen at all.

"It takes half a year, a year, or even two years to adapt to this change in rhythm, and even if he adapts to the new rhythm, it doesn't mean that the choices he makes will definitely break through the current results." Su Zu only had this sentence repeated in his mind now.

In 2007 there was the World Championships, and in 2008 there was the Olympics, and now the time is getting tighter.

During the 2006 European Golden League competition, Suzu also saw the Jamaican Lightning, and Bolt was significantly stronger than he was when he met in '04 and '05, and ran 20 seconds in the men's 200m in 2006. This means that the peak of Jamaican lightning is soon approaching.

This time, the change of pace and shortening the pace were completely different from the previous team in Hedao City, when Su Zu was still a fledgling, but he was fully implementing Li Zhizhong's training plan and ideas.

This time, it is active optimization, and after the technology is formed, it is necessary to further disrupt the original running rhythm and start to change the existing step count and rhythm.

It may seem like it's just a two-step shortening, but putting it on 100 meters means that the length of each step has to be increased.

And you have to gradually adapt to your cadence, really improve your speed, form brain and muscle memory, so that as long as you enter the arena, you can directly use your body instinct to run out.

In terms of lower limb strength, Su Zu's explosive power to support leg swings is already the top, and the explosive power of the legs comes from muscles. In general, weightlifters and bodybuilders are very strong in their leg muscles, and Suzu's leg muscles are in no way inferior. Thigh circumference is an important indicator to consider muscle strength, the standard thigh circumference of adult men is height multiplied by 0.293, Su Zu's height is 1.87 meters, so his current standard thigh circumference is 54.79 cm, but in fact, Su Zu's current leg circumference exceeds the standard by nearly 9 cm, reaching 63.6 cm, which is not inferior to some weightlifters or bodybuilders.

And the restriction of his further speed is that the current stride length is not enough, with his current leg strength, the maximum stride can also reach about 3 meters, but in different competitions, Su Zu's stride will always change to a certain extent.

In later generations, many people in China discussed and compared the stride length of Jamaican lightning and Su Bingtian. In the same 41 steps, the Jamaican lightning was able to run 100 meters, while Su Bingtian only ran about 87 meters.

Of course, stride length is not the absolute key to success, and you need to choose a suitable middle point between stride length and cadence. With Su Zu's height, supporting 44 or 43 steps to run a hundred meters is not a particularly large stride. However, such an adjustment will definitely cause a change in the starting and acceleration runs, and some series of stride lengths along the way.

The results of this adjustment are not necessarily positive, and it is very likely that after Su Zu adjusted to 43 steps, because the need for greater contact and rebound force between the ball of the foot and the ground affected the overall speed.

But in the current situation, Su Zu Li Zhizhong and the entire Su Zu research team are very clear that if he wants to break through again, in addition to improving the starting reaction, explosiveness, and speed retention ability, this stride must be changed to a certain extent.

A few days later, the track and field team training at the Haigen base discovered a very strange thing, Su Zu seemed to be enchanted.

Whether it's eating or sleeping, there seem to be words in his mouth, and in addition to completing normal training tasks, it seems that the whole person is completely addicted to it.

"45 Steps...... 44 Steps...... 43 steps ......"

In addition to constantly optimizing his pace and rhythm on the track and field track, Su Zu constantly recalled the scene of his running before going to bed at night.

Over and over again, I thought about myself from the time I stepped on the starting gear and started running after hearing the gunshots, one, two, three steps, all kinds of details and stride length were accurate.

Occasionally, when he suddenly felt that his stride was wrong, Su Zu would even jump up from the bed suddenly, and start counting again in great annoyance. Again, I designed a 100-meter length in my mind, adjusting my starting acceleration and the number of steps I would take along the way.

As the days passed, Su Zu conducted regular physical, strength, speed, endurance and rhythm training during the day, ran in the pool every day or two, and constantly reviewed in his mind at night the results of his training after changing the pace of his stride.

Simple, pure, and undisturbed, occasionally Su Zu has a feeling of returning to the time when the Hedao City team first trained under Li Zhizhong.

But such a peaceful life did not last long, on February 4, 2007, Li Chun of the lunar calendar, the third rehearsal invitation of the CCTV Spring Festival Gala had been sent, Su Zu had to temporarily leave the Haigen training base, and Zhang Pingqiu, Yu Yaling and others took a plane to the imperial capital.

Li Zhizhong still stayed at the Haigen training base, and Yuan Guohua conducted a detailed personal training plan for Zhang Peimeng, Wen Yongyi, and Su Bingtian.
