Talking about Ben Johnson. He ran somewhere between 10.40 to 10.45 in the rounds, quarter finals... In Helsinki in 1983. He didn't make it to the finals.
Why we're sprinters so slow in the early 80s?
See Mike Young's slideshare images 37-46:
http://www.slideshare.net/hpcsport/breaking-barriers-to-sprint-performanceWe know more than we knew then, and one of the things we know is that you can't actually train max velocity. We have gotten faster from improved acceleration and speed maintenance. And acceleration really doesn't mean weights. The primary difference is dynamic activities, including sleds, hills, and much more acceleration on the track. Power development to accelerate to a faster top speed, rather making belief that you can train that higher top speed. There is still weight training done, but coaches now realize it is less important than people used to think, and the Jamaican coaches like Glen Mills believe that 1/2 of strength training should be dynamic activities. We also know that squat strength of 450 pounds or so is needed to maximize acceleration in the first 10 meters, but it only works in the first 10 meters. Eccentric strength like drop and depth jumps work for a longer distance.
There's a video made this year showing Bolt lifting 635 on a 45 degree press, which is worth about 350 pounds in a true squat. But Bolt has gone to 30m in 3.78, while Ben did 3.80.
There is a youtube with Kim Collins being asked about training changes after his 6.47 60m last year. He mentioned emphasizing indoors more, more starts, more speed work, work on his arm mechanics. He did not mention weights at all.
