I don't think my opinion is worth of a hill of beans, but I would say, no, someone concentrating solely on sprints doesn't need an aerobic phase. In fact, I'd say someone who's only interested in 50s probably doesn't need an aerobic training at all. Once you get to 100s, then some aerobic training would be worthwhile. I truly like to read anyone's opinion really. And my participation to this thread is related to 50/100 specialists. Plain 50m free specialists tend to be rare.
