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".
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 ...
All of these factors make track and "football 40" performances essentially impossible to compare. The world best time for a "football 40" is 4.17 by Deion Sanders , while the extrapolated best for an Olympic-level athlete (including reacting to a starting gun) is 4.24 by Maurice Greene at the 2001 World Championships in Athletics .
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 ...
Typical scanning speed of an audio compact disc; the speed of signals (action potentials) traveling along axons in the human cortex. 1–1.5: 3.6–5.4: 2.2–3.4: 3.3–5.0 × 10 −9: Average walking speed—below a speed of about 2 m/s, it is more efficient to walk than to run, but above that speed, it is more efficient to run. 2.39: 8.53: 5 ...
The world record in the 100-meter dash in 1924 was 10.4 seconds, while in 1948, (the first use of starting blocks) was 10.2 seconds, and was 10.1 seconds in 1956. The constant drive for faster athletes with better technology has brought man from 10.4 seconds to 9.58 seconds in less than 100 years.
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.
