The phrase ‘Faster, higher and stronger’ not only serves as the motto of the Olympics, but also it plays a role in other athletic events. One example is the 100m sprint.
The first IAAF100m world record of 10.6 seconds was set by Don Lippincott (USA) in 1912. Usain Bolts set the current 100m world record of 9.58 second in World Championships in Berlin in 2009. It took around 100 years to remove 1.02 seconds from the first record.
Jim Hines was the first athlete who broke the 10 second limit in 1968. He set the record of 9.9 seconds in the 100 meter sprint during the semi-finals of the U.S Championships. At that time, official records were measured manually by watch. There were 3 judges recording time and at least 2 of their measurements had to be identical in order for the record to be considered official.
It can be difficult to break these records but we can always human limitation. According to the research by American professor Weyand, major difficulties arise at the threshold of 9.48 seconds for Men and 10.19 seconds for women.
For men, Usain Bolt's record is much closer to the what appears to be the human threshold. On the other hand, for women, Griffith-Joyer’s record is still not broken after 20 years, which is already far from the threshold.
In Korea, Guk Young, KIM set men’s 100m record of 10.23 seconds in 2010, while Young Sook, Lee set the women’s 100m record of 11.49 seconds in 1994.
I am looking forward to seeing records broken in World Championships Daegu 2011.
