Football is a project with high technical proportion, but absolute strength is not enough. You also need agility, coordination and other qualities. It is not accurate to measure professional players and amateurs simply by the difference between agility and explosive power. There is a technical term called core strength in football strength training. For professional players and amateurs, the difference of core strength is often bigger and more obvious than the difference of absolute strength. Many football fans know that going to the gym to gain muscle can obviously improve the physical confrontation ability in the game. But for professional players, simple equipment in the gym is not very helpful for training core strength. Elastic belt, ladders and even weirder things, which often appear in TV clips of the training of giants and clubs, are props for professional players to train their core strength. Of course, this is only superficial. In fact, the theory of core strength training has been very systematic, and the training methods are also varied. Therefore, professional players are far stronger than amateur players in absolute strength and core strength through long-term training accumulation. In fact, the exaggeration is that professional players and amateurs have different physical structures, that is, the difference between athletes and ordinary people. Physical qualities like Ronaldo are comparable to those of aliens.
In addition to the advantages accumulated by training, there are also great differences in innate physical qualities, just like the so-called "red and white muscles" that we all know. In fact, the selection of football materials has been very scientific and systematic from development to now. I've seen runners do tests on the running platform to measure their heart rate and so on. It's quite advanced In fact, there are two indicators that can clearly distinguish whether a person is a professional player or an amateur player, that is, the maximum oxygen uptake and the blood lactic acid concentration after exercise. Of course, the training the day after tomorrow, such as running laps, can also effectively improve these indicators. Harvey of Barcelona can run a distance of 13000m in a game, and can guarantee a pass of about100ft, with a success rate of over 90%, which is largely due to the advantages of these two indicators. Amateur players and professional players have played tricks, especially those who play man-to-man tasks, often find it too difficult to stare at someone else. Usually they are breathless after running for a while, and even if they catch the ball, it is difficult to complete the technical action.
The second is the difference in basic skills. In fact, not only the skills to deal with football are called basic skills, but also a series of techniques to control the body, such as running posture, which can be broadly classified as basic skills. Just find a professional football textbook, all the single skills and their training methods are recorded, and everyone can learn about these things from the book, so I won't compare them in detail here. So professionals can easily distinguish between professional players and football lovers on the court.
