Message: [QUOTE="Kaizen, post: 3536799, member: 6183"] [B]A biological limit[/B] Let’s take the men’s 100m sprint as our example. Humans cannot run at, say, the speed of light, so there must be a limit to how fast it is possible to run. The current world record for this event is [URL='https://www.iaaf.org/records/by-category/world-records']9.58 seconds[/URL], set by Usain Bolt in 2009. His [URL='http://www.runnersworld.com/newswire/ultimate-100-meter-time-927-seconds']average speed during this race was 10.43 m/s, with a top speed of 12.34 m/s[/URL]. Were it possible for him to run at this speed for the entire 100 m (impossible because of the stationary start), Bolt could have completed the race in 8.10 seconds. Interestingly, in a 150 m race in 2009 Bolt ran the [URL='https://www.iaaf.org/news/news/bolt-runs-1435-sec-for-150m-covers-50m-150m-i']last 100 m in 8.70 seconds[/URL] – a result of starting that last 100 m at speed. Mathematicians and biologists have both tried to predict the fastest 100 m sprint possible, with varying results. A [URL='http://jeb.biologists.org/content/211/24/3836']2008 study[/URL] (before current world record was set) used computer models and statistics to suggest a time of 9.48 seconds, mathematician [URL='http://www.wired.com/2008/08/bolt-is-freaky/']Reza Noubary[/URL] has suggested 9.44 s, and [URL='http://www.wired.com/2008/08/bolt-is-freaky/']other researchers[/URL] have suggested 9.45 seconds. These predictions are based on fitting a curve to the progression of the world record over time (check out [URL='http://condellpark.com/kd/sprintlogistic.htm#Maths']this link[/URL] for an explanation of the maths involved).
