Rep...Well, let's start with what we know for sure. Replays of the men's 100m final shows zero wind. I had mistakenly remembered a 0.1 m/s tailwind for the race. There was probably another race that evening that did have that ever so slight breeze. The maximum allowable wind for world records to be set is 2.0 m/s.<BR/><BR/>I find many references on the internet to times being adjusted due to both wind and altitude. Even on NBC one of the broadcasters about a minute after the race says "time adjusted officially to 9.69 seconds". I can not, however, find any sort of official rule book for the sport which would clearly say one way or the other whether adjustments are actually made. It's something that has stuck in my head from who knows where. But certainly many people out there routinely calculate adjustments, even if they aren't official.<BR/><BR/>They are common enough that someone has made an <A HREF="http://myweb.lmu.edu/jmureika/track/wind/index.html" REL="nofollow"><BR/>adjustment calculator</A> and put it on the web, and <BR/><A HREF="http://arxiv.org/PS_cache/physics/pdf/0102/0102039v1.pdf" REL="nofollow"><BR/>physicists in Canada</A> are writing papers about it.<BR/><BR/>Running at high altitude is beneficial to sprinters, as the air is thinner and offers less resistance. The lower O2 content doesn't effect them much over such short distances. 2000m elevation coupled with 2.0 m/s tail wind can aid a runner as much as 0.15 seconds over 100m. (Beijing is at about 45m elevation, so this was not a factor in Bolt's time.)<BR/><BR/>Ok, further research has turned up the <A HREF="http://www.iaaf.org/mm/Document/imported/42192.pdf" REL="nofollow"><BR/>IAFF Competition Rules</A> which makes no mention of adjusting times, but does mention that times for races up to and including the 10,000m are recorded to the next longer 1/100th of a second, that is 9.681 becomes 9.69.<BR/><BR/>And that is more on the subject than I ever wanted to know.Clarkhttps://www.blogger.com/profile/03145994948747483468noreply@blogger.comtag:blogger.com,1999:blog-7424335.post-61842657260993187742008-08-18T10:55:00.000-06:002008-08-18T10:55:00.000-06:00Clark, I'm interested in where you got your inform...Clark, I'm interested in where you got your information from. From what I can tell the tail wind for the 100 m final is officially listed at 0.0 mps (the upper limit for tailwinds in world record races is 2.0 mps). I've also never heard of the times being adjusted because of the wind. I thought they were adjusted according to rounding errors (i.e. the timer at the finish line showed 9.68, but the actual time was 9.6875 - which rounds to 9.69) and the speed of the sprinters start. I highly doubt that it was adjusted because of the wind.tysquihttps://www.blogger.com/profile/03952080446650385939noreply@blogger.comtag:blogger.com,1999:blog-7424335.post-3175930957876783642008-08-18T08:49:00.000-06:002008-08-18T08:49:00.000-06:00In sprints, world records can not be set if head/t...In sprints, world records can not be set if head/tail winds are too strong. The results from such races simply don't count towards records. Tyson Gay ran the 100m in 9.68 at the Olympic trials in June, but that didn't count as a world record because of the tail wind. In the case of Usain Bolt in these games, there was a very slight tail wind, and he actually crossed the line in 9.68 seconds. That time was then very slightly adjusted to 9.69 seconds which is what he would have run without that slight tail wind.Clarkhttps://www.blogger.com/profile/03145994948747483468noreply@blogger.comtag:blogger.com,1999:blog-7424335.post-23786283998891967242008-08-18T06:49:00.000-06:002008-08-18T06:49:00.000-06:00That was an inspirational post Tyler.

We have the exact same problem with the tivo-ing. We've been up way past midnight multiple nights in a row. And, while I am almost always falling asleep on the couch while watching I keep on doing it night after night.Sabrinahttps://www.blogger.com/profile/15431022305793390323noreply@blogger.com
