As a follow on to Chris' observation, I think sprinters need to train "enough" which is to say enough to do the race on which you're focused.
I've found training for the 50 is different from training for the 100 by a long shot. At least in the 50 free, the race is really about turnover and keeping your stroke together. You can also get away with not breathing in the 50, but if you try that in the 100 you'll be toast as soon as you make your second turn. Lifting weights helps in terms of turnover, but you still need to swim at least every other day (IMHO).
