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]
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]
During running, the speed at which the runner moves may be calculated by multiplying the cadence (steps per minute) by the stride length. Running is often measured in terms of pace, [54] expressed in units of minutes per mile or minutes per kilometer (the inverse of speed, in mph or km/h). Some coaches advocate training at a combination of ...
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.
For example, a runner who completes a fast 400 meter repetition at a sub-5-minute mile pace (3 minute km) may drop to an 8-minute mile jogging pace (5 minute km) for a recovery lap. Jogging is an effective way to boost endurance and improve cardiovascular health while placing less stress on the joints and circulatory system compared to more ...
The second half of the test involved subjects performing a 100-m sprint on a man-made track using radar to measure the forward speed of runners to create velocity-time curves. The main result of this study showed that the force application technique (rather than simply the total amount of force applied) is the key determinant factor in ...
The multi-stage fitness test was first described by Luc Léger [6] with the original 1-minute protocol, which starts at a speed of 8.5 km/h, and increases by 0.5 km/h each minute. Other variations of the test have also been developed, where the protocol starts at a speed of 8.0 km/h and with either 1 or 2-minute stages, but the original ...
