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 Usain Bolt. [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 fastest human footspeed on record is 44.7 km/h (12.4 m/s; 27.8 mph), seen during a 100-meter sprint (average speed between the 60th and the 80th meter) by Usain Bolt. [ 86 ] Speed over increasing distance based on world record times
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]
Jogging is running at a gentle pace; [1] its definition, as compared with running, is not standard. In general, jogging speed is between 4 and 6 miles per hour (6.4 and 9.7 km/h). In general, jogging speed is between 4 and 6 miles per hour (6.4 and 9.7 km/h).
Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis. [1] In athletics and track and field, sprints (or dashes) are races over short distances.
The world record for men is 12:35.36 (an average of 23.83 km/h) by Joshua Cheptegei of Uganda in Monaco set on 14 August 2020; The world record for women is 14:00.21 (an average of 21.43 km/h) by Gudaf Tsegay of Ethiopia in Oregon, United States set on 17 September 2023; The 10,000 metres is the longest standard track event.
Speed limit sign in the Republic of Ireland, using "km/h.". The SI representations, classified as symbols, are "km/h", "km h −1" and "km·h −1".Several other abbreviations of "kilometres per hour" have been used since the term was introduced and many are still in use today; for example, dictionaries list "kph", [3] [4] [5] "kmph" and "km/hr" [6] as English abbreviations.
Note: A circuit consists of running two shuttles followed by a 10 second rest period Table derived from "The Yo-Yo Intermittent Tests: A Systematic Review and Structured Compendium of Test Results" [4] and ESPNCricinfo [6] As a side note, "Speed Level" correlates exactly with "Running Speed (km/h)" using the formula: (Running Speed – 7.5) * 2.
