It took decades for the future of human beings to enter 6.50 seconds. It took decades for humanity to enter 6.40 seconds.

It took more than 10 years for mankind to enter 6.30 seconds. The first person to do so in the indoor race was Morris Green, whose 6.39 seconds was once considered the limit of the future that humans could not surpass.

In fact, this record has been held for a long time.

If it weren't for Su Shen reopening in this timeline.

It will also have to be maintained for more than 10 years before it will be broken.

And to record this thing, the higher your ability, the harder it will be to improve. It's not that you improve by 0.1, just as you were in the previous 0.1, it's a difficulty.

Even if you want to be more serious.

Most likely several times.

Or even a dozen times the difference.

After 6.30+, the next money of mankind is naturally to enter a new stage, which is the so-called 6.20+ stage.

Start at this stage.

This is the so-called real science, one of the existing testing limits.

But after this limit is raised, who is the first person to do it?

It is not known at this time.

After all, it seems that Su Shen, Powell, and Bolt are all people who have a chance.

And history, only the first person will be remembered, so whoever can be the first to break through the 6.30s and enter the field of 6.20+ will become the first person to leave a name in history. Originally, it was Su Shen in history, so now, will it still be him?

Whether it is the 60-meter category of the segment or the indoor race, the first person in human history who can run in 6.30s is Su Shen Bensu.

Now, he's just doing what he's supposed to do.

Of course, Green's words also caused an uproar.

The entire track and field world began to discuss whether this race, the first 6.20+ race in human history, would be born in Athens on February 25.

This is very hot.

The first person, who is a trailblazer and creator of a 6.20+.

Su Shen, Usain Bolt, Powell, choose one of the three.

The heads and posters of the three people began to be gradually put up in Athens, and as for the rest of the former, sorry, they couldn't go up at all.

Because this top showdown is born between these three people.

The rest of the people didn't have a chance to get involved.

At this time, Bolt's results were also brushed out————

6.34s。

Powell's latest 60m time is ————

6.35s。

Although both of them also let go, they still broke 6.35s and entered a super absolute future.

And this field is not accessible to ordinary people at all.

Historically, Green has never been in.

These three people are so terrible and terrifying.

"I'm looking forward to fighting the Soviet Union in Athens and I'm ready to do my best on the night of February 25 to get another gold medal around my neck." Bolt saw that Su Shen's results were so violent, and he had to stand up and respond, he never expected that Su Shen's guy would be so rolled: "I am participating in the 60m for the first time, but I am also here for the gold medal, because I am Usain. Bolt. ”

"I'm the fastest man in the world."

"Sue's results are amazing." When Powell saw the results, he immediately said: "This level shows that he is also ready, and I am also looking forward to the battle in Athens, because ...... I also worked hard for the whole winter training! I'm not going to be afraid of anyone! ”

"On the 60 meters, I am also the absolute king, and I am not afraid of Bolt coming."

"We'll see you on February 25."

……

At a training ground in Athens, Su Shen and his team made final adjustments.

Preparation activities are the exercises that athletes carry out to better participate in upcoming competitions or training, and are an indispensable and important part of sports activities. Quality, appropriate and adequate preparation activities are essential for athletes to be able to perform the next sport better.

For example, low-intensity aerobic exercise for medium and long periods of time: including jogging, cycling, skipping rope, doing exercises, etc., the main purpose is to increase body temperature, improve enzyme activity, increase metabolic rate, speed up nerve conduction, increase muscle contraction speed, and promote oxygen supply.

For example, elastic stretching and static stretching: including stretching exercises for various joints of the body, including head movements, lunge leg presses, bending over and holding knees, etc., the main purpose is to increase muscle elasticity, improve the ductility of ligaments and muscles, and relax tense muscle tissue.

For example, small load strength exercises: through their own body weight or small load weights, such as solid balls, small dumbbells, elastic bands, etc., to carry out multiple rapid exercises on some body parts, such as push-ups, squat jumps, throwing balls, etc., the main purpose is to warm up the muscles that are about to face high-intensity confrontation, activate muscle strength, and prevent sports injuries.

In the case of injured athletes, there are a few more that need to be added: for example, this group of people is divided into three categories: athletes who are currently injured but can continue to compete, those who have had injuries and have recovered from them, and those who currently have injuries that prevent them from competing. The third category is not able to compete, so the focus is on rehabilitation after a sports injury. For athletes who have had injuries but have recovered, it is necessary to design special preparation activities for their past injury history, including massage and traction of the injury site by specialized personnel, and activation and strengthening of related weak links, so as to put prevention measures in the most important position of preparation activities; For athletes who are currently injured but continue to compete, additional external means, such as oral administration, injection of drugs, wearing external protective gear, etc., should be taken to eliminate pain and fix the position of injury, and then strengthen the muscles around the affected area to prevent secondary damage to other parts of the athlete.

If Liu Xiang comes out to compete, what he has to do is need one more step.

Preparation for important competitions has always been a very particular situation, and whether you can do well or not means whether you can show your level in important competitions. Don't think that only the training system is more scientific, in fact, the warm-up and pre-game preparation are already too powerful compared to before.

The theoretical and operational basis is also beginning to take shape.

"The muscles test is somewhat slightly stiff and recommended. Myofascial combing: Through a series of auxiliary equipment such as practical foam rollers, hard balls, vibrating rods, or manual massage, the tense muscles and fascia are combed and relaxed, and a series of preparatory activities for athletes to return to their normal posture are myofascial combing. This is generally carried out at the front of training and competition, and at the same time, a certain degree of pain sensation also has the function of awakening and activating the central nervous system. ”

"The recent core test is a bit lacking in peaks, and core stability activation is recommended: some basic exercises for the core area of the body, pre-activating the main muscles around the spine and hip joint. It not only strengthens the muscles around the lumbar spine that are already weak in the human body, but also prevents damage to the spine; It also increases the stability of the core area, which is conducive to the transmission of force, and also reduces the leakage of energy to a certain extent, which has many functions. ”

"There is a problem with the wear and tear of the shoulder joint, and it is recommended to fully activate the shoulder joint recently: the shoulder joint mainly includes the scapular joint and the glenohumeral joint, and the muscles around the shoulder blade are equivalent to the gluteal muscles of the lower limbs in the upper limbs, which have strong stability and strength, but there are inertia problems for various reasons, so they must be activated in advance; The glenohumeral joint, on the other hand, has a relatively high level of motion and is also prone to injury. Therefore, we need to stabilize our scapula by strengthening the muscles that control the movement of the scapula, including the serratus anterior, rhomboid, trapezius middle and lower muscles, etc.; It strengthens the rotator cuff muscles to stabilize our shoulder joint. ”

"Running breathing rate is not smooth enough and is recommended. Respiratory activation: Activating our respiratory system by adjusting the breathing pattern, establishing the correct breathing action, and deepening the action of strengthening the breathing. This helps our respiratory system to enter the working state in advance, avoiding poles and difficulty breathing during exercise, and at the same time, the muscles that help breathe participate in expanding the oxygen metabolism capacity, increasing the breathing efficiency, and can delay the time of respiratory fatigue to a certain extent. ”

……

Su Shen sweats like rain here.

Because the Battle of Athens was imminent, the final adjustment could not be used for particularly high-intensity training.

Otherwise, injuries and physical load alone will be a huge problem.

Su Shen they are here to quickly conduct the final body weight test.

"Hb is normal and high."

"BUN is normal."

"CK is normal and low."

"T levels are normal."

Hb hemoglobin is the main component of red blood cells, its abbreviation is Hb, is a binding protein, each hemoglobin molecule is composed of one molecule of globin and four molecules of ferrous heme, globin accounts for about 96%, heme accounts for 4%. The hemoglobin content of healthy adult men in China is 12-16 grams per 100 ml of blood, with an average of 14 grams; The hemoglobin content of adult women is 11-15 grams, with an average of about 13 grams.

Because the Hb index is relatively stable and can reflect the physical performance status more sensitively, this index is often used in sports training to evaluate the functional status and training level of athletes, and predict the exercise ability. Hb, also known as hemoglobin or hemoglobin, its main physiological function is to transport O2 and CO2 in the body, and Hb also has the effect of maintaining the acid-base balance of body fluids to affect the body's body functions. Since Hb is related to O2 transport capacity, a decrease in Hb will also lead to a decrease in O2 supply, which in turn leads to a decrease in locomotor capacity. Therefore, Hb content directly affects the athletic ability of endurance athletes.

According to Ersha Island's assessment of the normal value of hemoglobin in athletes, too low or too high hemoglobin will affect the athlete's athletic ability. Below normal values, i.e. anemia appears, and the supply of oxygen and nutrients is insufficient, which inevitably leads to a decrease in the ability to work. When the Hb value is too high, the number and crit of red blood cells in the blood will inevitably increase. It has been proved that according to the average Hb of each athlete, the individual differences in Hb value can be divided into three types, namely, high type, normal type and low type. Each basic type can be divided into two subtypes, namely: the standard deviation (SD) greater than 1 g% is the large fluctuation, and less than 1 g% is the small fluctuation. Therefore, it is theoretically possible to divide the hemoglobin of athletes into six types. However, there are only four types that are often encountered in practical work: those with high fluctuations, those with large normal fluctuations, those with small normal fluctuations, and those with small normal fluctuations. Exercise training practice has proved that the best is the one with high hemoglobin value and small fluctuation. This type of athlete can tolerate heavy exercise training and is better at endurance sports. However, the hemoglobin value is low and the fluctuation is small.

Su Shen's Hb is "that is, the one with high volatility and small fluctuation".

It's almost the best Hb division, you must know that Hb is not the higher the better, nor the lower the better, Su Shen's "that is, the high fluctuation smaller" is the best.

In terms of CK, under normal circumstances, the structure of muscle cells is intact and functional, so that CK rarely penetrates the cell membrane, so the change of CK activity can reflect the degree of adaptation of muscle cells to exercise training. CK activity is significantly increased after strenuous exercise, and changes in CK activity can be used as a sensitive biochemical profile to assess the stimulation of exercise-induced skeletal muscles and to understand muscle injury and its adaptive recovery. This is because we adjusted our training before the game, because the load was a little less and the muscle stimulation was lower than normal training, so naturally this indicator went down.

Creatine kinase (CK) acts as a catalyst for the reversible transfer of high-energy phosphate bonds between adenosine triphosphate and phosphocreatine.

As we all know, the key enzymes for energy replenishment and ATP recovery after short-term intense exercise are closely related to energy balance and transfer during and after exercise. For example, at rest, the range of total serum CK activity is:

Adult men: 1 0~1 00U/L, adult women: 1 0~60U/L.

And athletes are clearly more than that.

Male athletes: 1 0~300U/L, female athletes: 1 0~200U/L.

The main reasons for the increase in serum enzyme activity caused by exercise are the increase in cell membrane permeability due to exercise traction, the increase in the release of catecholamines, or tissue cell damage, etc., which cause the increase in enzyme leakage from cells into the blood. Therefore, the magnitude of the increase in serum enzyme activity and the speed of recovery after training can reflect the intensity and amount of exercise, as well as the body's adaptation. This is very suitable for the preparation of major competitions, such as the change of serum CK, LDH, ALT, and AST activity after heavy exercise training, which can indirectly assess the exercise load and reflect the damage and repair status of tissues.

With CK, it can be divided into three subtypes, namely: a CK-BB (cKl), a brain-type isozyme, which is mainly distributed in brain, prostate, lung and other tissues; (2) CK2, a mixed isozyme, mainly distributed in myocardium; TricK-deletion (cK3), a muscular isoenzyme, is mainly distributed in skeletal muscle and myocardium. In normal human serum, cK is the main coffee, accounting for 94%~96% of the total cK, so the content of CK can roughly replace the content of cK. The phosphocreatine produced by CK catalyzes a chemical reaction contains high-energy phosphate bonds, which are a direct source of energy for muscle contraction. The change of CK concentration can be used as an important biochemical indicator to assess the degree of stimulation of muscles and understand the micro-injury of skeletal muscle and its adaptation and recovery, and the concentration of cK in serum can be regularly detected before the competition, which can better grasp the adaptation of athletes' muscles to training load, and the culprit of the sudden and violent increase in K: after a long-term intraining and sudden high-intensity training, cK can reach more than 1000u/L; (2) Sudden stimulation of a certain part with high intensity can make the cK rise to more than 2000u/L; 3. Skeletal muscle and other muscle lesions can make CK reach more than 3oooU/L. For athletes whose cK suddenly rises above l000u/L, they should be aware of the situation in time to avoid further muscle damage.

Having said so much, the significance of pre-competition K detection is that the peak of CK should be avoided before the competition, and only by restoring the cK in the athlete's serum to a certain range before the competition can they show a good physical state and achieve good results in the competition.

All things considered, Su Shen's CK is now at this level, which is very reasonable.

"Su, the basic test is done, the problem is not big, there are almost no physiological problems, just take iron supplements." Randy looked at the physical exam report and said, "Physically, you are ready. ”

Because of the adjustment of training before the competition, the load has become smaller, which is a hard indicator, and you can intuitively see the current physical state of the athletes, and it is not a void at all.

Su Shen saw that there was no problem, so he adjusted his mind and said, "Don't worry, this time Athens, I will definitely go all out." ”

Taking a deep breath, with a slight sweat on his forehead, Su Shen poured down a large mouthful of sports nutrition solution and said:

"Be sure to put the championship and the record."

"Don't take it all down."
