The future of human beings has entered 6.50 seconds, which took decades. The future of human beings has entered 6.40 seconds, which took decades.

The future of mankind has entered 6.30 seconds, but it took more than 10 years. The first person to do it in the indoor competition was Morris Green. His 6.39 seconds back then was once considered a limit of future that humans could not surpass.

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

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

It will also be maintained for about 10 years before it will be broken.

Moreover, when recording this thing, the higher your ability, the more difficult it will be to improve. It does not mean that if you increase 0.1, it is the same as you on the previous 0.1.

Even if you want to be serious.

It's probably several times.

Even a dozen times the gap.

After 6.30, the next Qian Cheng vision of mankind will naturally enter a new stage, which is the so-called 6.20 stage.

Start from this stage.

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

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

It is unknown at present.

After all, it seems that Su Shen, Powell, and Bolt are all people with opportunities.

And history only remembers the first person, so whoever can break through 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 a 60-meter range in segments or indoor races, the first person in human history to run into the 6.30s is Su Shen Bensu.

Now, he is just doing what he should do.

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

The entire track and field industry has begun to discuss whether this game will be born in Athens on February 25.

This is very popular.

The first person, who is the pioneer and creator of 6.20.

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

The avatars and posters of the three people began to be placed gradually in Athens. As for the other former, I'm sorry, I can't go up at all.

Because this top showdown was born between these three people.

The rest of the people have no chance to intervene.

At this time, Bolt's scores were also improved——

6.34s.

Powell's latest 60-meter score is--

6.35s.

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

And this field is not something that ordinary people can enter.

In history, Green has never been in.

These three people are so terrifying and terrifying.

"I am looking forward to fighting Su in Athens. I am ready. On the evening of February 25, I will do my best to hang a gold medal around my neck again." Bolt saw that Su Shen's performance was so violent, and he had to stand up and respond. He never expected that Su Shen would actually be like this: "It's my first time participating in the 60m, but I also came for the gold medal, because I am Usain Bolt."

“I am the fastest person in the world.”

"Su's results are surprising." Powell immediately spoke after seeing the results: "This level means he is ready, and I am also looking forward to the battle in Athens, because... I have also worked hard on the whole winter training! I will not be afraid of anyone!"

"I am also the absolute king on 60 meters. I am not afraid of Bolt coming."

"We'll know when we meet on February 25."

...

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

Preparation activities are exercises performed by athletes to better participate in upcoming competitions or training, and are an indispensable and important part of sports activities. Carrying out high-quality, appropriate and sufficient preparation activities is a necessary prerequisite for athletes to better complete the next exercise.

For example, medium- and long-term low-intensity aerobic exercises: including jogging, cycling, skipping rope, doing exercises, etc. The main purpose is to increase body temperature, increase enzyme activity, increase metabolic rate, accelerate nerve conduction speed, increase muscle contraction speed, and promote oxygen supply.

For example, elastic vibration stretching and static stretching: including stretching movements for various joints of the body, including head movements, lunge leg pressing, bent down and hugging the knees, etc. The main purpose is to increase muscle elasticity, improve ligaments and muscle ductility, relax tense muscle tissue, etc.

For example, small load strength exercises: Do several rapid exercises on some body parts through heavy objects with weights or small loads, such as solid balls, small dumbbells, elastic bands, etc., such as push-ups, squat jumps, ball throws, 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.

If you are injured athletes, some more need to be added: for example, this group of people is divided into three categories of athletes who currently have injuries but can continue to compete and train, have injuries and have recovered from injuries that have made them unable to compete. The third category is unable to compete, so the focus is on rehabilitation training after sports injuries. For athletes who have injuries but have recovered, special preparation activities should be designed for their past injury history, including the massage, traction and activation and strengthening of related weak links by specialists, and the prevention means should be placed in the most important position in the preparation activities; for athletes who currently have injuries but still continue to compete, additional external force measures should be taken, such as oral administration, injection of drugs, wearing external protective gear, etc. to eliminate pain and fix the injury position, and then strengthen the muscles around the affected area to prevent compensation and cause secondary damage to other parts of the athlete.

If Liu Xiang comes out for a competition, he needs one more step to do.

Preparation for important competitions has always been a very particular situation. Whether you can do it well means whether you can show your own level in important competitions. Don’t think that only the training system is more scientific. In fact, warm-up and pre-match preparations are much stronger than before.

The theoretical and operating foundations are also begun to be formed.

"Muscle tests are a little stiff, so it is recommended to use. Myofascial combing: Through a series of auxiliary equipment such as practical foam rollers, hard balls, vibrators, etc., or manual massage, the tension muscles and fascia are combed and relaxed, so that athletes can restore their normal posture to their body is myofascial combing. This is usually placed at the forefront of the training and competition. At the same time, a certain degree of pain also has the function of awakening and activation of the central nervous system."

"The recent core tests are not peak enough, and it is recommended to carry out core stability activation: some basic exercises in the core area of ​​the body, pre-activate the main muscles around the spine and hip joints. This not only strengthens the already weak muscle groups around the lumbar spine and prevents spinal damage; it also increases the stability of the core area, which is conducive to the transmission of force, and reduces energy leakage to a certain extent, and has many functions."

"There is a problem with the loss of the shoulder joint. It is recommended to fully activate the shoulder joint recently: the shoulder joint mainly includes the scapular joint and glenohumeral joint. The muscles around the scapula are equivalent to the gluteal muscles of the lower limbs in the upper limbs, with extremely strong stability and strength. However, due to various reasons, there are inertia problems, so it must be pre-activated; the glenohumeral joint is relatively high in mobility and is easily injured. Therefore, we must stabilize our scapula by strengthening the muscles that control scapula movement, including the serrata anterior muscle, rhombus muscle, middle and lower trapezoid muscles, etc.; we are strengthening our shoulder joints by strengthening the rotator cuff muscles."

"The running breathing frequency is not smooth enough, so it is recommended to do it. Respiration activation: that is, by adjusting the breathing mode, establishing correct breathing movements, and deepening and strengthening breathing movements, in order to activate our respiratory system. This helps our respiratory system to enter the working state in advance, avoiding extremes and breathing difficulties during exercise. At the same time, it helps the respiratory muscles participate in expanding oxygen metabolism, increasing breathing efficiency, and delaying the time of respiratory fatigue to a certain extent."

...

Su Shen sweats violently here.

Because the Athens battle is imminent, the final adjustment cannot be carried out with particularly high-intensity training.

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

Su Shen and the others are here to quickly conduct the final body mass test.

“Hb is normally high.”

“BUN is normal.”

“CK is normal and low.”

“The T level is normal.”

Hb hemoglobin is the main component in red blood cells. Its abbreviation is Hb. It is a binding protein. Each hemoglobin molecule is composed of one molecule of globin and four molecules of ferroferrous heme. Globin accounts for about 96%, and heme accounts for 4%. The hemoglobin content of healthy adult men in my country 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.

Since the Hb index is relatively stable and can reflect the physical function state more sensitively, this index is often used in sports training to evaluate the athlete's functional status, training level, and predict exercise ability. Hb is also called hemoglobin or hemoglobin. Its main physiological function is to transport O2 and CO2 in the body. At the same time, Hb also maintains the acid-base balance of body fluids, thereby affecting the body's body's function. Since Hb is related to O2 transportation capacity, Hb decreases, O2 supply will also decrease, which will lead to a decrease in exercise ability. Therefore, the Hb content directly affects the exercise ability of endurance athletes.

According to Ersha Island's assessment of the normal hemoglobin value of athletes: low or too high hemoglobin will affect the athlete's athletic ability. Below the normal value, that is, anemia occurs, insufficient supply of oxygen and nutrients, which will inevitably lead to a decrease in working ability. When the Hb value is too high, the number and packing of red blood cells in the blood will inevitably increase. Practice has proved that according to the average Hb value of each athlete, the individual differences in the 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: if the standard deviation (SD) is greater than 1 gram, which is greater than 1 gram, which is less than 1 gram, which is less than 1 gram. Therefore, in theory, the athlete's

There are six types of hemoglobin. However, there are only four types that are often encountered in actual work: those with low fluctuations, those with large fluctuations, those with small fluctuations, and those with low fluctuations. Sports training practice has proved that those with high hemoglobin values ​​and small fluctuations are the best. This type of athlete can tolerate high load exercise training and engage in endurance activities, while those with low hemoglobin values ​​are the worst.

The Hb detected by Su Shen is "that is, those with low fluctuations".

It is almost the best Hb division. You should know that the higher the Hb, the better, nor the lower the better. Su Shen, the "that is, the smaller the fluctuation" is the best.

In terms of CK, under normal circumstances, the complete and functional muscle cell structure is normal, so that CK passes out of the cell membrane, so changes in CK activity can reflect the degree of adaptation of muscle cells to exercise training. After strenuous exercise, the change in CK activity can be used as a sensitive biochemical condition for evaluating the stimulation of motor skeletal muscles and understanding the muscle damage and its adaptation recovery. This is because we adjusted the training before the game, because the load becomes smaller, and muscle stimulation is lower than normal training, so naturally this indicator will fall back.

Creatine kinase (CK) acts to catalyze the reversible transfer of high-energy phosphate bonds between adenosine triphosphate and creatine phosphate.

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

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

This chapter is not over, please click on the next page to continue reading! And the athletes are obviously more than that.

Male athlete 1 0～300U/L Female athlete 1 0～200U/L.

The main reason for increased serum enzyme activity is that exercise pull increases cell membrane permeability, increase catecholamine release, or tissue cell damage, etc., causing enzyme leakage from cells to enter the blood. Therefore, the increase in serum enzyme activity and the speed of recovery after training can reflect the intensity of exercise, the size of the training volume and the body's adaptability. This is very suitable for major competition preparations. For example, changes in serum CK, LDH, ALT, and AST activities after training can indirectly assess the exercise load and reflect the damage and repair status of tissues.

In addition, CK can be divided into three subtypes, namely: 1ck-bb(ckl), brain isozyme, mainly distributed in brain, prostate, lung and other tissues; 2ck-boat (ck2), mixed isozyme, mainly distributed in myocardial muscle; 3ck-deletion (ck3), muscle isozyme, mainly distributed in skeletal muscle and myocardial muscle. Normal people's serum is mainly 94% to 96% of the total amount, so the content of ck can be roughly replaced by ck. The creatine phosphate produced by catalytic chemical reactions contains high-energy phosphate bonds, which are the direct source of energy during muscle contraction. Changes in ck concentration can be used as an important biochemical indicator for evaluating the degree of stimulation of muscles and understanding of skeletal muscle microscopic injuries and their adaptation and recovery. Regular detection of ck concentration in serum before the game can better grasp the degree of adaptation of athletes' muscles to training load.

The original evil of sudden and violent rise of ck: 1. After a long-term lack of training, ck can reach more than 1000u/l; 2. Suddenly stimulation of a certain part can increase ck by up to 2000u/l; 3. Skeletal muscle and other muscle lesions can cause ck by up to 300u/l. For athletes whose ck suddenly rises more than 1000u/l, they should be informed in time to avoid further muscle damage.

Having said so much about detecting K before the game, the meaning of: the peak of ck should be avoided before the game. Only by restoring the ck in the athlete's serum to a certain range before the game can it show good physical condition and achieve good results in the game.

Taking it into consideration, Su Shen’s CK is now at this level, which is very reasonable.

"Su, the basic test is done, there is no big problem, there are almost no physiological problems, just make up the iron." Randy looked at the physical examination report and said, "This can be said that you are ready for it physically."

Because the training was adjusted before the competition, the load became smaller and these were hard indicators. You can intuitively see the current physical condition of the athletes and it is not vague at all.

Seeing that there was no problem, Su Shen adjusted his mind and said, "Don't worry, I will do my best this time at Athens."

After taking a deep breath, with a slight sweat on his forehead, Su Shen poured a large mouthful of exercise nutrient solution and said:

"It's important to put the championship and record."
