It's scary that women aren't hitting Flo Jo's times from 88. They are still 0.1 behind her second best and 0.25 behind her WR. This Zelinka lady is no where near that ball park in times. Her hurdles time was over 0.3 behind Pearson in an event where technique rules, not brute power. Pearson has the fourth fastest time in history and the only recent time to crack 12.3 in 20 years. Interestingly the top 4 times are all white women.
Yet in the mens pure sprint since Seould, Bolt has done 9.58, a whole 0.2 faster than Ben Johnson went. Blake, Bolt, Gatlin, Gay and Powell have all gone faster. Add in Greene and Montgomery and it's glaringly obvious the drugs help men more than women in explosive sports. The womens 400m WR from Canberra back in 87 by a Russian woman still stands. Perec and Freeman never even came close. Over a second off for Perec and almost 2 for Freeman. Actually that event is a lot slower now than 10 years back.
The 100m is about 11 intervals. The start and each subsequent 10m of the race. Adding Ben Johnson's PB's for each together, his fastest possible time if he put them all together would have been 9.55 seconds. I am not shocked Bolt is close to that. I bet in training he and the other four big boys will all be running faster than they do in actual events. They'd be literally glowing red during training. Hot enough to set off any Geiger counter and then cool down for the event and whatever testing. I reckon Bolt can run 9.4 if he wants and the rest can crack 9.6 no trouble...high 9.5 so one or two if they get their heads right.
When the ladies start beating Flo Jo's times and those of the former Soviet bloc countries, then we should starting crapping our pants.
