The record is 44.72 km/h (27.78 mph), measured between meter 60 and meter 80 of the 100 meters sprint at the 2009 World Championships in Athletics by speed. [4] [5] (Bolt's average speed over the course of this race was 37.578 km/h or 23.35 mph.) [6] Compared to quadrupedal animals, humans are exceptionally capable of endurance, but incapable of great speed. [7]
The endurance running hypothesis is a series of conjectures which presume humans evolved anatomical and physiological adaptations to run long distances [1] [2] [3] and, more strongly, that "running is the only known behavior that would account for the different body plans in Homo as opposed to apes or australopithecines".
Quadrupedalism is sometimes referred to as being "on all fours", and is observed in crawling, especially by infants. [1] In the 20th century quadrupedal movement was popularized as a form of physical exercise by Georges Hebert. [2] Kenichi Ito is a Japanese man famous for speed running on four limbs in competitions. [3]
Crawling or quadrupedal movement is a method of human locomotion that makes use of all four limbs. It is one of the earliest gaits learned by human infants, [1] and has similar features to four-limbed movement in other primates and in non-primate quadrupeds. [2]
Kenichi Ito (Japanese: いとう けんいち, Hepburn: Itō Ken'ichi, real name: 伊藤 健一; born 8 May 1982) is a Japanese athlete from Tokyo.He holds the Guinness World Record for running 100 meters on all four limbs, setting a best time of 15.71 seconds in the Komazawa Olympic Park in Tokyo, 6 November 2015, shaving 0.15 seconds off the previous record of 15.86 seconds by Katsumi ...
In collegiate cross-country races in the United States, men race 8,000 or 10,000 meters, depending on their division, whereas women race 6,000 meters. [18] The Summer Olympics features four long-distance running events: the 3000 metres steeplechase (which also involves jumping over barriers and water), the 5000 metres , 10,000 metres and ...
Humans spontaneously switch from a walk to a run as speed increases. In humans, the preferred transition speed from walking to running typically occurs around 2.0 m/s (7.2 km/h; 4.5 mph), although slight differences have been shown based on testing methodology. [1] [2] [3] [4]
In terms of judging a person's speed, the best method of timing is through lasers which start and stop the times when passed through. A laser start (from a stationary position) is more accurate for measuring pure speed as it does not register a runner's reaction time, however, this method of timing a 40-yard dash can affect the accuracy by as much as 0.5 seconds with the manual stopwatch method.
