100 Meter Dash

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, :)

while he has been a world class 100m runner he has lost just 1 100m race, to Asafa Powell shortly before the Beijing Olympics, 9.88 to 9.89 I think.

I recall Bolt should have won, with about 10m to go, Bolt thinks Powell is too far ahead and stops running hard, he underestimates how much Powell loses ground late in the race and Powell giveing everything and dipping to the line just holds off Bolt's jogging.

The Jamaica national record holder for the 100 meters is world record holder Asafa Powell, with a time of 9.74 seconds. -------------------------------------------------- Usain Bolt with 9.58s on 16th August 2009

It takes me just under 3 minutes flat out, I'm a 38 year old man, do quite a bit of swim training and complete in triathlons.

1) Clayton Parros, HS: Seton Hall Prep, Time: 45.71

2) Dennis Mitchell, HS: Edgewood?, Time: 46.02

It's very good. He must be a very fast kid. Ask him if he is interested in any sports and he can achieve great things in life.

Linford Christie 9.87s

defentally were spikes there a kind of rinning shoe and are very light , just lookthem up if you dont no what ima talking about and once you have them at your race they will have thease things call blocks they will help you so much (:

17 seconds is horrlble u try and get 14-15sec is okay
