May 10, 1930
Southern Pacific AAU Meet
Finish of the 100 yard dash.
Frank Wycoff finishing with a world record time in the 100 yard dash… 9 2/5 seconds… at the Southern Pacific AAU meet. (Not recognized by the International Union because he used starting blocks.) Matched the time without using blocks one month later at Stagg Field in Chicago. World record recognized.

Does fully automatic timing now guarantee fair
timing?
Nope(And it’s mostly due to the Starter!)
![Page 10: Starter Position and FAT Final - ATOM OfficialsPosition+and+FAT+Final.pdf · -a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before](https://reader034.vdocuments.site/reader034/viewer/2022042109/5e88f4c16ed0b00d332fa728/html5/thumbnails/10.jpg)
Factors in AthleteReaction Times
(D) The time for sound to cross the distance between the starter and the competitor.
(A) The time for the auditory signal to be recognized by the competitor and a reaction sent to the muscles.
(G) Time shaved off when a competitor anticipates (guesses) the start.
![Page 11: Starter Position and FAT Final - ATOM OfficialsPosition+and+FAT+Final.pdf · -a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before](https://reader034.vdocuments.site/reader034/viewer/2022042109/5e88f4c16ed0b00d332fa728/html5/thumbnails/11.jpg)
Reaction Time = (D) + (A) – (G)
![Page 12: Starter Position and FAT Final - ATOM OfficialsPosition+and+FAT+Final.pdf · -a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before](https://reader034.vdocuments.site/reader034/viewer/2022042109/5e88f4c16ed0b00d332fa728/html5/thumbnails/12.jpg)
G
Guessing.
![Page 13: Starter Position and FAT Final - ATOM OfficialsPosition+and+FAT+Final.pdf · -a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before](https://reader034.vdocuments.site/reader034/viewer/2022042109/5e88f4c16ed0b00d332fa728/html5/thumbnails/13.jpg)
The one false start disqualification in high school and the starter intentionally varying the interval between “set” and the gun both serve to discourage guessing.
Unfortunately some still choose to play the guessing game.
![Page 14: Starter Position and FAT Final - ATOM OfficialsPosition+and+FAT+Final.pdf · -a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before](https://reader034.vdocuments.site/reader034/viewer/2022042109/5e88f4c16ed0b00d332fa728/html5/thumbnails/14.jpg)
Reaction Time = (D) + (A) – (0.000s)
While (G) is totally unpredictable, ideally it should be zero for any competitor reacting to the gun and not guessing.
![Page 15: Starter Position and FAT Final - ATOM OfficialsPosition+and+FAT+Final.pdf · -a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before](https://reader034.vdocuments.site/reader034/viewer/2022042109/5e88f4c16ed0b00d332fa728/html5/thumbnails/15.jpg)
A
Auditory signal.
![Page 16: Starter Position and FAT Final - ATOM OfficialsPosition+and+FAT+Final.pdf · -a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before](https://reader034.vdocuments.site/reader034/viewer/2022042109/5e88f4c16ed0b00d332fa728/html5/thumbnails/16.jpg)
Auditory Signal A study released in 2008 by the University of Alberta in Edmonton indicates the loudness of a sound has an effect on reaction time.
People hearing a 120 decibel signal reacted on average 0.018 seconds sooner than those hearing an 80 decibel signal.
So, what about (A), eh?
![Page 17: Starter Position and FAT Final - ATOM OfficialsPosition+and+FAT+Final.pdf · -a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before](https://reader034.vdocuments.site/reader034/viewer/2022042109/5e88f4c16ed0b00d332fa728/html5/thumbnails/17.jpg)
Frei Universitat Berlin determined in 1998 that nearly all weapons used to start races in track generate a 160 decibel sound 1 meter from the gun.
Even at 150 feet, starter’s gun is six times louder than the strongest sound tested in the Canadian study.
![Page 18: Starter Position and FAT Final - ATOM OfficialsPosition+and+FAT+Final.pdf · -a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before](https://reader034.vdocuments.site/reader034/viewer/2022042109/5e88f4c16ed0b00d332fa728/html5/thumbnails/18.jpg)
Do other factors make a difference, even in a “normal” starting line environment?
Maybe…

Spanish startle reflex experiments done prior to the Barcelona Olympics showed (A) values as small as 0.030 seconds.
Probably not relevant since competitors expect the gun.

(A) is flexible but on average is 0.120 second due to inconsistent recognition of gun versus background noise.

Current Position (Figure 5): “(The starter will) take a position, 8-20 feet from the starting line, on the inside
of the track. Make sure you have a line of vision that includes the entire starting line…. The second assistant will signal the first assistant (when) ready and then the first assistant will signal the starter to give the set command.”
“The first assistant should be in a position on the opposite side of the track from the starter… (and) should be in a position on the line…. The first assistant will be responsible for the outside lanes (5-8).”
“The second assistant should be on the infield positioned on the line, opposite the first assistant. The second assistant will be responsible for the inside lanes.”

Rationale for Modification: Moving the starter farther down the track reduces the FAT difference for the field from 0.026 seconds to 0.013 seconds. All competitors cannot fit into the starter’s central vision. Assistant starter 2 is moved outside and the two officials split the field. Assistant starter 1 is away from the track and in line with the back of the field to see early motion/slippage for all lanes. Assistant starter 1 is also located in the starter’s central vision.

…but based on current practice,
- we give the equivalent of a 19-inch advantage to a 50 second quarter miler in Lane 3 over one with equal talent in Lane 9.
- a 100 meter sprinter closest to the starter has the opportunity to move forward nearly a foot before the most distant competitor even has the chance to react to the gun.
- a half-miler in a center alley has a heel on the starting line advantage over middle distance runners in alleys at the edges of the track.

Positioning Assistant Starters1st Priority - Officials make calls on violations in their central vision field.
2nd Priority - The optimal view of a competitor’s start is an unobstructed profile or frontal oblique view.
3rd Priority - If a profile view is not practical, a straight on frontal view of a competitor is preferable to any view from
behind.
4th Priority - No panning of central vision is necessary for any official to observe their assigned competitors.
