Huh?

Mens 400m 41/59% (aerobic v anaerobic)
mens 800m 60/40% (aerobic v anaerobic)

I am sure we can all pick holes in the research.

Firstly most of the research was done on treadmill, of the research done on the track how do you record this info? Wouldn’t that affect the result?

ooops sorry about that, got a little jumbled. My bad.
