Energy systems for 400m dash

I was recently sent a document which reviewed the literature on energy systems in the 400m. The findings for aerobic contribution in the men’s 400m race (in the 46sec range) varied from 18% up to high 50%.

This doesn’t suprise me.

I think a more important question might be (and I think P.J. might have been alluding to this) Is how much training should be aerobic vs speed vs speed end vs special end. when training a 400 runner. This is really what I’m interested in.
