Bolt is a very talented sprinter
The important components of 1, 100 meter project are step frequency and stride length. Bolt is the tallest man sprinter in the world, with 1.96 meters. In the world series, Bolt ran 100 meters at a pace of 40.95 4 1. His stride is also the most prominent.
2. Scientists found that there is a substance called ACTN3 in Jamaican sprinters, which can improve the speed of muscle strength contraction. The hormone content and red blood cell content of Jamaican athletes are higher than the average level of ordinary people. With the high-intensity training of sprint events, they can recover fatigue faster (effectively prevent muscle strain) and ensure high-intensity training. Bolt has outstanding sports physiological ability.
Why didn't Bolt run with all his might in the race?
Bolt took part in the world competition, and was ahead of other sprinters in most of the men's 100 meter events. He was in the leading position in the later sprint stage. In particular, it set a world record of 9.58 seconds. Coaches Glenn Mills and Bolt realized that it was impossible to innovate the 100-meter performance in training, so Bolt was in a leading position in the 100-meter sprint and would finish the race with high-speed inertia.
Bolt later took part in the World 100 meter race, and most of the time, after a clear lead, he crossed the 100 meter finish line along the high-speed inertia in the sprint stage. The audience wondered why Bolt didn't run with all his might in the sprint.
In the training of 100 meters, in order to make the athletes run at high speed, the coach should relax, pace, be expensive and coordinate the technical movements. It is often used in speed training. When running on the way to the highest speed, let the athletes run for another 20 ~ 30 meters along the speed inertia to experience the relaxation ability in the process of controlling technical movements.
Bolt is in the leading position among the world famous sprinters, so he is in the leading position in the midway running of the world 100-meter event, and runs to the finish line along the high-speed inertia in the sprint stage. In the long run, it has become normal for Bolt to apply the means of high-speed inertia running to the sprint stage in the training process, so when watching Bolt's game, he wondered why Bolt didn't run with all his strength. Bolt can only apply high-speed inertial running (sprint training means) to the 100-meter event if he maintains the absolute acceleration advantage among the world-famous sprinters. It shows that Bolt's running skill is first-class in the 100 meter event, and the whole technical movement has reached the degree of automation, which stands out in the fierce competition. The technology of controlling the sprint stage makes the audience feel the relaxed feeling of Bolt, thinking that Bolt is not running with all his strength.
The 100-meter event is the extreme sport of human beings. It describes the high-intensity anaerobic exercise of human body in exercise physiology, and the anaerobic metabolic function accounts for more than 98%. The race of 100 meters is one thousandth of a second, especially in the final sprint stage of 100 meters, keep the high speed of 1, maintain the good function of the central nervous system and save the energy consumption of the body; 2. Technical movements that conform to the principles of human mechanics; 3. Overcome air resistance in the whole 100 meter race.
The human central nervous system affects muscle strength in two ways: 1, changing the number of technical movements that muscles participate in; 2. It is to change the frequency of motor nerve impulses that dominate iliac muscles. Under the adjustment of nervous system, improve the coordination between active muscle and cooperative muscle, antagonistic muscle and supporting muscle in the process of sprint technical action. Because the contraction of synergid and supporting muscles is accelerated, the ability of resisting muscle relaxation is improved, and the active muscles can complete technical movements more effectively. High-speed inertia running can improve the high tension of human central nervous system, and make the central nervous system play the role of rapid coordinated contraction of muscles in fierce competition. Efficient completion of the 100-meter technical work, saving excessive consumption of anaerobic energy supply.
The 100 meter event is on the runway with a width of 1.22 meters, and air resistance should be overcome during the competition. The whole technical action should conform to the mechanics principle of human body, such as: fingers slightly bend when the upper arm swings, elbow joint shrinks less than 90 degrees when the upper arm swings forward to increase the swing speed, and elbow joint swings more than 90 degrees around the center of human torso when the upper arm swings backward; When the thigh swings forward, the calf and thigh are closed at the knee joint, and the heel is close to the hip, and the radius is reduced. The technology that conforms to the principles of human mechanics is rational, fast, coordinated, coherent and smooth. Reasonable technical movements overcome air resistance, so that the human body can run a straight distance in the whole 100-meter running process, and prevent excessive heat consumption and slow down the running speed in the later process.
The whole 100 meter race, especially the sprint race in the third stage, will cause problems in the functional parts of the body, leading to a decrease in running speed and excessive energy consumption. The technology of the 100-meter event has reached the level of automation, which is an important indicator for high-level athletes. In the fierce competition with opponents in high-speed running, keep relaxed, reasonable, coherent and smooth technical movements. In the process of high-speed running, running 20 30 meters with the wind is an important means in sprint training. Bolt, a world-famous sprinter, can run with the tide at high speed in the competition. Let the public watching the game feel that Bolt runs the human extreme events easily, naturally and smoothly. It makes people feel why Bolt didn't run with all his strength in the game.
