Usain Bolt
is the fastest human on Earth with a personal best of 9.58
seconds in the 100 metres sprint. Bolt
holds the second fastest time of 9.63 seconds, the current
Olympic record, and set two previous world records in the
event. In the 200 metres, Bolt's personal best of 19.19 s is the
world record. This was recorded at the 2009 World Championships
in Athletics in Berlin against a headwind of -0.3 m/s. This
performance broke his previous world record in the event, his
19.30 s clocked in winning the 2008 Olympic 200 metres title.
Bolt has been on three world-record-setting Jamaican relay teams.
The first record, 37.10 seconds, was set in winning gold at the
2008 Summer Olympics. The second record came at the 2011 World
Championships in Athletics, a time of 37.04 seconds. The third
and current pending world record was set at the 2012 Summer
Olympics, a time of 36.84 seconds.
Bolt holds the 200 metres world teenage best results for the age
categories 15 (20.58 s), 16 (20.13 s, world youth record),
17 (19.93 s) and 18 (19.93 s, world junior record).
He holds the 150 metres world best set in 2009, during which he ran
the last 100 metres in 8.70 seconds, the quickest timed 100 metres ever.
He set Olympic and World records for the 100 metre, 200 metre, and along with
his teammates, the 4x100 metre relay at the 2008 Beijing Olympic
Games. These gold medal performances made him the first man in
history to set world records in all three events at a single
Olympics. Earlier in his career, "Lightning" Bolt distinguished
himself with a 200-metre gold medal at the 2002 World Junior
Championships, making him the competition's youngest-ever gold
medalist and the first junior sprinter to run the 200 metre in
under 20 seconds.
The current World record for the 100 m sprint is 9.58 seconds and
the Olympic record is 9.63 seconds. These are over a second
better than the time of 10.8 seconds run by a number of athletes
in the 1890's and over two seconds better than that achieved at
the 1896 Olympic Games, a dramatic increase in performance.

What accounts for this increase in speed? Yellow yam or
years of scientific research to monitor and devise the best
methods of training??
