Tokyo 2020

SPRINTERS are allowed ZERO false starts at the Tokyo 2020 Olympics, and if found guilty will be instantly disqualified.From January 2010 onward, the official track and field false start regulation indicated that any athlete starting within 100 milliseconds of the gun being fired would be disqualified from the race.

Research has found that a reaction time faster than one-tenth of a second is impossible for a human, and the runner is therefore deemed to have anticipated the gun.
On the ‘Track & Field 101: Rules’ on the Olympics website, it states: “If a sprinter commences his or her starting motion from the set position before the Starter’s gun is fired, it is deemed a false start. The first false start of a race results in an automatic disqualification to the offending runner.”
How can they detect a false start?
False start detection systems were introduced in 1979 and Omega’s false start detection system made its Olympics debut at the Los Angeles Olympics Games.
In major athletics competitions, reaction times are currently detected using IAAF accredited false start detection systems.
These systems determine athletes reaction time using encased accelerometers or force sensors fixed to the rear of the starting block rail to detect changes in force or acceleration exerted on the blocks through the feet.
RT’s can now be instantly calculated accurately to 0.001 of a second, but for results, are recorded to the nearest 0.01 second.
For athletics and specifically sprint athletes reaction times and overall sprint time detection methods have improved dramatically since the original 1896 Olympic Games.
Were false starts previously allowed?
Originally, before 2010, the “one-and-done” regulation was implemented meaning one false start per race in events up to 400 metres would be allowed rather than one false start per athlete as in the past.
This means the athlete making the second false start of a race, breaking the accepted reaction time of 0.10 seconds, will be disqualified regardless of whether he or she was responsible for the first one.
However, sprinters would often take advantage of the previous false start rules, purposely jumping the gun either to play mind games with their competition and set them on edge before the race or use the extra leniency to predict the gun and gain bonus milliseconds from their efforts.
So, World Athletics just decided to just ban any false starts – it’s one and YOU’RE OUT.
Famous false starts at previous track and field events
Usain Bolt
At the 2011 IAAF World Championships in Athletics in Daegu, South Korea, Usain Bolt, 100-meter world record holder, jumped the gun in the 100-meter final over a year after the new regulations had been put into place.
Bolt walked off the track, head in hands, only to watch his Jamaican teammate Yohan Blake take the gold.

Jon Drummond
Drummond’s infamous “I did not move!” plea after his disqualification at the 2003 World Athletics Championships in Paris.
Drummond protested his disqualification by storming into the infield, repeatedly yelling in front of officials and laying on the track.
His tantrum delayed the 100-meter final by ONE HOUR.

Linford Christie
The 1992 Olympic 100-meter champion was disqualified under an even older false-start rule.

Before 2003, any sprinter could false start once and get away with just a warning however Christie reacted early twice, delayed the competition and refused to leave the track.
This was the first time a previous champion was unable to defend his title live on TV.

THE decathlon is for those athletes who are just gluttons for punishment.It is the great all-around test in athletics – a 10-event contest covering the whole range of running, jumping, throwing and hurdling disciplines, spread over two days.

What does the decathlon consist of?
Decathletes are usually masters of no discipline, but strong in all areas of track and field.
The decathlon is just for male athletes – women compete in the heptathlon.
A perfect score in the decathlon is 1,000 points in each event for a cumulative score of 10,000 points, over the ten events.
The gruelling decathlon consists of:

Pole vault
High jump
Long jump
Javelin
Shot put
Discus
110-metre hurdles
100 metres
400 metres
1500 metres

So gruelling that athletes only get a maximum of 30 minutes rest in between events.
Factor in stretching, toilet breaks, water refuelling and coach input – well that’s less than a formula one pit-stop.

Who are the greatest decathletes of all time?
United States’ Jim Thorpe became the first winner of the decathlon in 1912 although he broke amateur rules by playing professional baseball.
Thorpe had all of his Olympic titles deleted, although after his death they were later reinstated.
Fast forward some 110 odd years and Ashton Eaton’s victory at the 2016 Olympics was the 14th decathlon gold medal for the USA, who have been the most dominant nation in the event by a long way as no other country has won more than two gold medals.
He also became the fastest 100-metre runner in a decathlon, crossing the line at 10.21 seconds.

Compare that to the world record of 9.58 seconds set by Usain Bolt at the 2009 World Championships – not bad for someone who also competes in nine other events!
Team GB’s most famous decathlete is Daley Thompson, who was unbeaten in the decathlon for nine years, from 1978 to 1987, winning two Olympic gold medals, and at the age of 61 he still holds the British record.
His 8,847 points, set in 1984, is a marker of Thompson’s brilliance and a measure of how far British men in the decathlon trail in his wake. More
