It took decades for mankind to reach 6.50 seconds. It took several decades for the future of mankind to reach 6 seconds 40.
It still took 10 years for the future of mankind to reach 6 seconds and 30 seconds. The first person to do it in the indoor competition was Maurice Green. His time of 6.39 seconds was once considered to be the limit of human future that was difficult to surpass.
In fact, this record has been maintained for a long time.
If Su Shen hadn't reopened on this timeline.
It will also take another 10 years before it is broken.
And recording this thing, as your ability is higher, the difficulty of improving it becomes more and more difficult. It doesn't mean that if you improve by 0.1, it will be the same as the previous 0.1. It is a difficulty.
Even if you want to be more serious.
Most likely several times.
Even a gap of more than ten times.
After 6.30+, mankind’s next financial journey will naturally enter a new stage, which is the so-called 6.20+ stage.
Start with this stage.
This is the so-called real science, one of the current testing limits.
But after this limit is raised, who is the first person to do it?
It is currently unknown.
After all, it seems that Su Shen, Powell, and Bolt are all people who have a chance.
And history will only remember the first person, so whoever can be the first to break through the 6.30s and enter the 6.20+ field will become the first person to leave his name in history. In the original history, it was Su Shen, so now, will it still be him?
Whether it is the 60-meter category in the sectional or indoor competition, the first person in human history who can run 6.30 seconds is Sushen Bensu.
Now, he is just doing what he should do.
Of course, Green's words also caused an uproar.
The entire track and field world has begun to discuss whether this game, the first 6.20+ game in human history, will be held in Athens on February 25.
This is so hot.
The first person who is a trailblazer and creator on a 6.20+.
Su Shen, Bolt, Powell, choose one.
The heads and posters of the three people began to be gradually placed in Athens. As for the rest of the former, sorry, they couldn't go up at all.
Because this time the top showdown was born between these three people.
The rest of the people have no chance to intervene.
At this time, Bolt’s results also came out————
6.34s.
Powell’s latest 60-meter result is————
6.35s.
Although both of them let go, they still broke through 6.35 seconds and entered a super and absolutely promising field.
And this field is simply not accessible to ordinary people.
Historically, Green has never entered.
These three people are so terrifying and terrifying.
"I'm looking forward to fighting Su in Athens. I'm ready. On the night of February 25, I will go all out to put a gold medal around my neck again." Bolt saw Su's achievements He was so violent that he had to stand up and respond. He never expected that this guy Su Shen would be so involved: "This is my first time to participate in the 60 meters, but I also come here for the gold medal, because I am Yousse." Um. Usain Bolt.”
"I'm the fastest man in the world."
"Su's results are surprising." After seeing the results, Powell said immediately: "This level shows that he is well prepared. I am also looking forward to the game in Athens because... I have worked hard throughout the winter training! I won’t be afraid of anyone!”
"I am also the absolute king at 60 meters. I am not afraid even if Bolt comes."
"We will find out when we meet on February 25."
…
At a training ground in Athens, Su Shen and the team were making final adjustments.
Preparatory 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, suitable and sufficient preparation activities is a necessary prerequisite for athletes to be able to better complete the following sports.
For example, medium- and long-term low-intensity aerobic exercise: including jogging, cycling, skipping, doing exercises, etc., the main purpose is to increase body temperature, increase enzyme activity, increase metabolic rate, speed up nerve conduction speed, increase muscle contraction speed, and promote oxygenation. supply.
For example, elastic stretching and static stretching: include stretching exercises for various joints of the body, including head movements, lunging legs, bending and holding knees, etc. The main purpose is to increase muscle elasticity and improve ligaments and muscles. ductility, relax tense muscle tissue, etc.
For example, small-load strength exercises: use your own body weight or small-load heavy objects, such as medicine balls, small dumbbells, elastic bands, etc., to perform multiple rapid exercises on some body parts, such as push-ups, squat jumps, ball throws, etc., mainly The purpose is to warm up the muscles that are about to face high-intensity confrontation, activate muscle strength, and prevent sports injuries.
If it is an injured athlete, some additional points need to be added: For example, this group of people is divided into three categories: those who currently have injuries but are able to continue training for competitions, those who once had injuries and have recovered, and those who currently have injuries that prevent them from competing for training. Athletes. The third category cannot compete, so its focus is on rehabilitation training after sports injuries. For athletes who have had injuries but have now recovered, special preparation activities should be designed based on their past injury history, including massage and traction of the injured area by professionals, as well as activation and strengthening of related weak links, so as to integrate preventive measures. Place it at the most important position in preparation for activities; for athletes who are currently injured but continue to compete, additional external means should be taken, such as oral administration, injection of drugs, wearing external protective gear, etc. to eliminate pain and fix the position of the injury , and then strengthen the muscles around the affected area to prevent compensation and secondary damage to other parts of the athlete.
If Liu Xiang comes out to compete, he will need to take one more step.
Preparing for important games has always been a very demanding situation. Whether you can do it well means whether you can show your level in important games. Don't think that only the training system is more scientific. In fact, the warm-up and pre-match preparations are already much stronger than before.
The theoretical and operational foundations are also beginning to form.
"The muscle test is slightly stiff, so it is recommended to use myofascial combing: through a series of auxiliary equipment such as practical foam rollers, hard balls, vibrators, or manual massage, the tense muscles and fascia can be combed and relaxed to help athletes recover. A series of preparatory activities for the body's normal posture is myofascial grooming. This is generally performed at the forefront of training and competition. At the same time, a certain degree of pain also has the function of awakening and activating the central nervous system."
"The recent core test is not peak enough. It is recommended to carry out core stability activation: some basic exercises for the core area of the body to pre-activate the main muscles around the spine and hip joints. It not only strengthens the already weak muscle groups around the lumbar spine of the human body, but also prevents The spine column is damaged; it also increases the stability of the core area, which is conducive to force transmission, and also reduces energy leakage to a certain extent, which has many functions."
"There is a problem with the wear and tear of the shoulder joint. 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 scapula are equivalent to the gluteal muscles of the lower limbs in the upper limbs, and have extremely strong stability and strength, but due to various reasons there is an inertia problem, so it must be activated in advance; the glenohumeral joint is relatively highly mobile and easy to be injured. Therefore, we need to strengthen the muscles that control scapula movement, including the serratus anterior. , rhomboids, middle and lower trapezius muscles, etc. to stabilize our scapula; and stabilize our shoulder joints by strengthening the rotator cuff muscles.”
"The breathing rate during running is not smooth enough. It is recommended to perform breathing activation: that is, by adjusting the breathing pattern, establishing correct breathing movements, and deepening and strengthening the breathing movements to activate our respiratory system. This helps our respiratory system Enter the working state in advance to avoid extremes and breathing difficulties during exercise. At the same time, the participation of muscles that help breathing expands oxygen metabolism, increases respiratory efficiency, and can delay the onset of respiratory fatigue to a certain extent."
…
Su Shen is sweating profusely here.
Because the war in Athens was about to take place, I couldn't do any particularly intensive training for the final adjustments.
Otherwise, injuries and physical load alone will be a huge problem.
Su Shen and the others quickly performed the final physical quality test here.
"Hb is normally high."
"BUN is normal."
"CK is normal and low."
"T levels are 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 ferrous 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 more sensitively reflect the body's functional status, this index is often used in sports training to evaluate athletes' functional status, training level, and predict athletic 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 and affects the body's physical functions. Since Hb is related to O2 transport capacity, if Hb is reduced, O2 supply will also be reduced, which will then lead to a decrease in exercise capacity. Therefore, Hb content directly affects the athletic ability of endurance athletes.
According to Ershadao’s evaluation of the normal value of hemoglobin for athletes: too low or too high hemoglobin will affect the athlete’s athletic ability. If it is lower than the normal value, anemia will occur, and the supply of oxygen and nutrients will inevitably lead to a decrease in working ability. When the Hb value is too high, the number and packed volume of red blood cells in the blood will inevitably increase. Practice has proved that according to the average Hb value of each athlete, individual differences in Hb values can be divided into three types, namely high type, normal type and low type. Each basic type can be divided into two subtypes, namely: those with a standard deviation (SD) greater than 1 g% are those with large fluctuations, and those with a standard deviation (SD) greater than 1 g% are those with small fluctuations. Therefore, athletes' hemoglobin can theoretically be divided into six types. However, there are only four types that are often encountered in actual work: those with high fluctuations and small fluctuations, those with normal fluctuations, those with small normal fluctuations and those with low fluctuations and small fluctuations. Exercise training practice has proven that those with high hemoglobin values and small fluctuations are the best. This type of athlete can tolerate heavy-load exercise training and is better engaged in endurance sports. Those with low hemoglobin values and small fluctuations are considered worse.
The Hb detected by Su Shen is "high with little fluctuation".
It is almost the best Hb classification. You must know that Hb is not higher, the better, nor is it lower, the better. Su Shen, who is "higher and less volatile" is the best.
In terms of CK, under normal circumstances, the structure of muscle cells is complete and the functions are normal, so that CK rarely penetrates the cell membrane, so changes in CK activity can reflect the degree of adaptation of muscle cells to exercise training. CK activity increases significantly after strenuous exercise. Changes in CK activity can be used as a sensitive biochemical condition to evaluate the stimulation of exercise skeletal muscles and to understand muscle damage and its adaptation and recovery. This is because we adjusted the training before the game. Because the load is smaller and the muscle stimulation is lower than normal training, this indicator will naturally fall back.
Creatine kinase (CK) catalyzes the reversible transfer of high-energy phosphate bonds between adenosine triphosphate and creatine phosphate.
As we all know: the key enzyme for energy replenishment during short-term intense exercise and ATP recovery after exercise is 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 10～100U/L and adult women 10～60U/L.
And athletes are obviously more than that.
Male athletes 1 0～300U/L and female athletes 1 0～200U/L.
The main reason why exercise causes an increase in serum enzyme activity is that the stretch of exercise increases the permeability of cell membranes, increases the release of catecholamines, or causes tissue and cell damage, which causes an increase in enzymes leaking from cells into the blood. Therefore, the amplitude of the increase in serum enzyme activity and the speed of recovery after training can reflect the intensity of exercise and training volume, as well as the body's adaptation. This is very suitable for use in preparation for major competitions. For example, changes in serum CK, LDH, ALT, and AST activities after heavy exercise training can indirectly assess exercise load and reflect tissue damage and repair status.
In addition, CK can be divided into three subtypes, namely: CK-BB (cKl), brain-type isoenzyme, mainly distributed in brain, prostate, lung and other tissues; ②cK-BB (CK2), mixed isoenzyme Enzyme, mainly distributed in myocardium; cK3 (cK3), muscle-type isoenzyme, mainly distributed in skeletal muscle and cardiac muscle. Normal human serum is dominated by cK-caffeine, accounting for 94% to 96% of the total cK content. Therefore, the content of CK can roughly replace the content of cK-caffeine. Creatine phosphate produced by CK through 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 to evaluate the degree of muscle stimulation and to understand micro-damage of skeletal muscles and their adaptation and recovery. Regular detection of CK concentration in serum before competition can better understand the adaptation of athletes' muscles to training load. The culprits of the sudden and severe increase in degree K: after a long period of no training and sudden high-intensity training, cK can reach more than 1000u/L; ② A sudden high-intensity stimulation of a certain part can increase cK up to more than 2000u/L; three skeletal muscles And other muscle diseases can make CK reach more than 3000U/L. For athletes whose cK suddenly rises above 1000u/L, they should learn about the situation in time to avoid further muscle damage.
Having said so much, the significance of testing K before competition is: the peak of CK should be avoided before the competition. Only by restoring the cK in the athletes' serum to a certain range before the competition can they show good physical condition during the competition. ,Get good grades.
Taking all things into consideration, Su Shen's CK is currently at this level, which is very reasonable.
"Su, the basic tests are done. There are no big problems. There are almost no physical problems. Just take a good iron supplement." Randy looked at the physical examination report and said: "It can be said that physically, you are ready."
Because the training is adjusted before the competition, the load becomes smaller, which is a hard indicator. You can intuitively see the athlete's current physical condition, and it is not fake at all.
When Su Shen saw that there was no problem, he adjusted his mind and said: "Don't worry, I will go all out in Athens this time."
Taking a deep breath, with a slight amount of sweat on his forehead, Su Shen took a large gulp of sports nutrition solution and said:
"Must bring championships and records."
"You can't take them all down."
