100 Meter Dash

well for the 2008 olympic trials they were: 100 m. freestyle-men:51.59 women:57.19 100 m. backstroke-57.99 women:1:04.59 100 m. butterfly-men:55.59 women:1:02.39 100 m. breaststroke-men:1:04.69 women:1:12.59

about 16.81

Prior to 1976, race times were only kept to the tenth of a second. As of January 1, 1950 the world record in the 100 meter dash was 10.2 seconds and had been achieved by four athletes: Jesse Owens, Harold Davis, Lloyd LaBeach, and Barney Ewell.

10.23 by Tamunosiki Atorudibo of Nigeria (DOB: 21/3/85) - 23/3/02

I'm 12 yrs old and my best time is 13.32 (i'm a girl) and I have competed in races and won overall. I think an average time would be 14 or 15 seconds.

That was Jim Hines of the United States at the U.S. National Championships in June, 1968 with a hand timed 9.9. He then became the first to run an electronically timed 100m under ten seconds at the 1968 Summer Olympics with a 9.95.

They are running a race, so they need to be fast. It is a relatively short distance, so runners run very fast in it, so a runner needs to build a high level of speed in order to win. It is the fastest race and shows who can run at the greatest speed.

That means you ran 20 meters in one second, which is about 66 feet per second. This sounds very impossible, but in miles per hour, it was 237,600 mph. (The math: 20 meters=66 feet. 66 feet per second times 60 equal 3960 feet per minute. Times 60 again gives you 237,600 feet per hour. 60 second in a minute, 60 minutes in an hour.) then divide 237,600 feet by 5,320 and the answer is 44.66 mph. There are 5,320 feet in a mile.

ATP-PC system Adenosine triphosphate.- phosphocreatine

phosphocreatine is broken down into phosphate and creatine molecules. as with any bonds that are broken energy is released. The phosphate molecule bonds to ADP (adenosine diphosphate) which produced an ATP molecule. This ATP molecule is used within cells to make energy.

It depends on the pool. Most competitive swim meets take place in 8-lane or 10-lane pools. Meets taking place in 10-lane pools typically fill the entire pool for the preliminary heats. In other words, all 10 lanes are taken up by swimmers. However, in the semi-finals and finals, only 8 lanes are used. This keeps the two outside lanes empty.

However, meets can take place in pools of any size. There can be 6-lane pools or 4-lane pools. It is not always the same.

Fort Worth OD Wyatt - 1998 - 39.76 seconds.

The reality is that there is no single "official" time in the 40-yard dash at a Combine.

That said, Bo Jackson has the best verifiable time at a Combine with his 4.12 clocking at the New Orleans Superdome in 1986.

I assume you are referring to the 40 yard dash as it applies to American Football. Currently, there is no official recognition of any 40 yard dash time. The 40 yard dash, as measured by the NFL combine, uses a method slightly different than standard track & field. In track and field, the runner reacts to the starting gun, where as the NFL combine allows the runners to start whenever they want, with the timers starting precisely when the runner does. This gives the combine method around a .15 second advantage. Also, combine participants are timed using 2 methods - by coaches with hand-held stopwatches and electronically.

With that said, the fastest 40 yard dash runners on the planet are most likely world-class sprinters (Asafa Powell, Tyson Gay, Maurice Greene, Usain Bolt) whose track and field times would translate to very low 4 second range NFL combine-style 40 times.

Regarding the fastest 40 ever run by an NFL player, there are lots of players noted to have been clocked around 4.1, such as Darrell Green, Deion Sanders, Raghib Ismail, Joey Galloway to name but a few. There are also many notable burners over the years who could have no doubt ran in the 4.1 range, such as Willie Gault, Bob Hayes, Cliff Branch and so on. There have been pure sprinters who have tried their hands at pro football who also should be mentioned, such as Renaldo Nehemiah, Alexander Wright and Jimmy Hines.

But it is Olympic athlete, Ben Johnson, who was believed to have run 40 yards faster than any human in history. Johnson is best known for injecting steroids and winning the 100 meters at the 1988 Olympics in Seoul in 9.79 seconds, only to have his gold medal and world record stripped after failing a post-race drug test.

Timing officials have since broken down that famed race into 10-meter increments, and Johnson was so preposterously fast that he went through 50 meters in 5.52 seconds and 60 meters in 6.37 - both under the current world records at the time at those distances. He went through 40 yards that day in 4.38 seconds. But, no matter how fast he was on steroids, Usain Bolt's legal 9.69 (9.55 without slowing) 100m time (40 yards of it) blows it away. Usain Bolt's 40 yard during his 100m record was likely a VERY low 4 such as 4.09 or 4.02.

Usain Bolt - He ran a time of 9.58 seconds in Berlin in 2009.

Men: Maurice Greene of the United States - 9.87 Women: Marion Jones of the United States but her medal was taken away in 2008 after she admitted to steroid use.

just back from a meet today. average time was 44-45 seconds. to qualify for aau at 7, must run 37 approximately.

A 12.5-second 100m equates to a time of 4.572 seconds in the 40-yard dash.

From a young age, Bolt was interested in sports. However it was not until his high school cricket coach encouraged him to get into track and field events that he realized his passion for sprinting.

Florence Griffith Joyner-10.49sec

Nine runners have broken 44 seconds in the 400 meter run:

1) Michael Johnson, United States - 43.18
2) Harry 'Butch' Reynolds, United States - 43.29
3) Jeremy Wariner, United States - 43.45
4) Quincy Watts, United States - 43.50
5) LaShawn Merritt, United States - 43.75
6) Danny Everett, United States - 43.81
7) Lee Evens, United States - 43.86
8) Steve Lewis, United States - 43.87
9) Larry James, United States - 43.97

Its a USA Lockdown. The USA has not lost at this event every time they competed in it in the Olympics after 1976.

The USA has not lost the relay in a very, very long time (unless DQ by performance enhancing drugs)

14:34.56 set by Grant Hackett, of Australia

Ah, what a lovely question! 400 meters is one lap around a standard track. So, if you were to walk or run around a field track that is 400 meters long, you would complete one lap. Just imagine the gentle breeze and the beautiful scenery as you take that lap - what a delightful experience!

The first person whoever moved 100 meters did.

1968 Summer Olympics in Mexico City.

Jim Hines of the United States was the first athlete to run an electronically timed 100 meter dash in under 10 seconds when he ran a 9.95 in the finals at the 1968 Summer Olympics in Mexico City.

around 16 seconds for an adverage runner i think, :)
