Sprinting is a sport that requires development of footspeed.. Footspeed, or sprint speed, is the maximum speed at which a human can run. It is affected by many factors, varies greatly throughout the population, and is important in athletics and many sports, such as association football, Australian rules football, American football, track and field, field hockey, tennis, baseball, and basketball.
For sprints, World Athletics maintains that world records and other recognised performances require: a wind assistance of not more than two metres per second (7.2 kilometres per hour (4.5 mph)) in the direction of travel; fully automatic timing (FAT) to one hundredth of a second; and no use of performance-enhancing substances.
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.
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: 5.35: 7.97 × 10 −9: World record time 50m freestyle swim 5.78: 20.81: 12.93: 1.928 × 10 −8: World record time marathon [13] 6–7: 20–25: 12–15: 1.8–2.3 × 10 −8 ...
Reindeer can reach a running speed of almost 50 miles per hour(80 km), though most recorded speeds are between 25 and 35 miles per hour (40-56 km), which is still quite impressive.
Therefore, people feel that they are not working as hard by switching from walking to running, even though their energy expenditure has increased. Humans would have to transition to running at much faster speeds than 2.0 m/s (4.5 mph) in order for the transition to represent a decrease in energy consumption. [citation needed]
"You get a lot more muscle recruitment overall when you run faster than when you run slower (for longer)," says McGrath. This works the fast-twitch muscle fibers, which help for quick movements.
Limitations of animal running speed provides an overview of how various factors determine the maximum running speed. Some terrestrial animals are built for achieving extremely high speeds, such as the cheetah, pronghorn, race horse and greyhound, while humans can train to achieve high sprint speeds. There is no single determinant of maximum ...
