Who has the biggest blow?
The problem of identifying the "very-most" is as old as the world. From the beginning of the publication of the Guinness Book of Records, where all athletes are trying to get, we can name all the athletes with the strongest blows.
Speaking of who has the hardest blow in martial arts, boxing punches are most often implied. The unit for measuring them is kilogram or newton (about 0.1 kg). The most powerful blow currently (confirmed) has Mike Tyson - 800 kg. Such power is enough not only to knock out an opponent, but also to kill. For comparison, it is enough to give an example, in order to knock out an opponent, it is enough to hit the chin with a force of 15 kg (150 newtons).
Continuing the theme of the strongest blow in boxing, we will touch the most famous professional - Mohammed Ali. According to unconfirmed data of some witnesses, the force of the impact of this great athlete was almost 1000 kg! If we take our Nikolai Valuev, then his average blow "weighed" 510 kg.
The strongest blow to the players was marked by the German striker Lukas Podolski.The record was set at the 2010 World Cup in the game with the Australian team - 56 m / s (201 km / h). Prior to this match, the record was with Roberto Carlos - 55 m / s and 198 km / h, respectively.
The speed of serving in tennis is measured relatively recently, but there is also a record holder here - this is American Andy Roddick. The record was recorded on June 11, 2004 at the Tournament of the Royal London Club. The speed of the ball after giving Andy was 246.2 km / h. Even among the professionals of tennis there are not many players who are capable of serving the ball at a speed of more than 200 km / h. Note that in his youth, Roddick was a weak and low tennis player.
